Who is this article for?  This article should be read by educators at all levels of higher education looking to embed and integrate sustainability into curriculum, module, and / or programme design.

Premise:

The critical role of engineers in developing sustainable solutions to grand societal challenges is undisputable. A wealth of literature and a range of initiatives supporting the embedding of sustainability into engineering curricula already exists. However, a practicing engineering educator responsible for achieving this embedding would be best supported by a practical framework providing a step-by-step guide with example resources for either programme or module/course-level embedding of sustainability into their practice. This practical framework illustrates a tested approach to programme wide as well as module alignment with SDGs, including further resources as well as examples of implementation for each step. This workflow diagram provides a visual illustration of the steps outlined below. The constructive alignment tool found in the Ethics Toolkit may also be adapted to a Sustainability context.

For programme-wide alignment:

1. Look around. The outcome of this phase is a framework that identifies current and future requirements for programme graduates.

a. Review guidelines and subject/discipline benchmark documents on sustainability.

b. Review government targets and discipline-specific guidance.

c. Review accreditation body requirements such as found in AHEP4 and guidance from professional bodies. For example, IChemE highlights the creation of a culture of sustainability, not just a process of embedding the topic.

d. Review your university strategy relating to sustainability and education. For example, Middlesex University signed up to the UN Accord.

e. Consider convening focus groups with employers in general and some employers of course alumni in particular. Carefully select attendees to represent a broad range of employers with a range of roles (recruiters, managers, strategy leaders, etc.). Conduct semi-structured focus groups, opening with broad themes identified from steps a through d. Identify any missing knowledge, skills, and competencies specific to particular employers, and prioritize those needed to be delivered by the programme together with the level of competency required (aware, competent, or expert).

2. Look back. The outcome of this phase is a programme map (see appendix) of the SDGs that are currently delivered and highlighting gaps in provision.

a. Engage in critical reflective analysis of the current programme as a whole and of individual modules.

b. Conduct a SWOT analysis as a team, considering the strengths, weaknesses, opportunities, and threats of the programme from the perspective of sustainability and relevance/competitiveness.

c. Convene an alumni focus group to identify gaps in current and previous provision, carefully selecting attendees to represent a broad range of possible employment sectors with a range of experiences (fresh graduates to mid-career). Conduct semi-structured discussions opening with broad themes identified from steps 1a-e. Identify any missing knowledge, skills, and competencies specific to particular sectors, and those missing or insufficiently delivered by the programme together with the level of competency required (aware, competent, or expert).

d. Convene a focus group of current students from various stages of the programme. Conduct semi-structured discussions opening with broad themes identified from steps 1a-e and 2a-c. Identify student perceptions of knowledge, skills, and competencies missing from the course in light of the themes identified.

e. Review external examiner feedback, considering any feedback specific to the sustainability content of the programme.

3. Look ahead. The goal of this phase is programme delivery that is aligned with the SDGs and can be evidenced as such.

a. Create revised programme aims and graduate outcomes that reflect the SDGs. The Reimagined Degree Map and Global Responsibility Competency Compass can support this activity.

b. Revise module descriptors so that there are clear linkages to sustainability competencies or the SDGs generally within the aims of the modules.

c. Revise learning outcomes according to which SDGs relate to the module content, projects or activities. The Reimagined Degree Map and the Constructive Alignment Tool for Ethics provides guidance on revising module outcomes. An example that also references AHEP4 ILOS is:

“Apply comprehensive knowledge of mathematics, biology, and engineering principles to solve a complex bioprocess engineering challenge based on critical awareness of new developments in this area. This will be demonstrated by designing solutions appropriate within the health and safety, diversity, inclusion, cultural, societal, environmental, and commercial requirements and codes of practice to minimise adverse impacts (M1, M5, M7).”

d. Align assessment criteria and rubrics to the revised ILOs.

e. Create an implementation plan with clear timelines for module descriptor approvals and modification of delivery materials.

For module-wide alignment:

1. Look around. The outcome of this phase is a confirmed approach to embedding sustainability within a particular module or theme.

a. Seek resources available on the SDGs and sustainability teaching in this discipline/theme. For instance, review these examples for Computing, Chemical Engineering and Robotics.

b. Determine any specific guidelines, standards, and regulations for this theme within the discipline.

2. Look back. The outcome of this phase is a module-level map of SDGs currently delivered, highlighting any gaps.

a. Engage in critical reflective analysis of current modules, as both individual module instructors and leaders, and as a team.

b. Conduct a SWOT analysis as a module team that considers the strengths, weaknesses, opportunities, and threats of the module from the perspective of sustainability and relevance of the module to contribute to programme-level delivery on sustainability and/or the SDGs.

c. Review feedback from current students on the clarity of the modules links to the SDGs.

d. Review feedback from external examiners on the sustainability content of the module.

3. Look ahead.

a. Create introduction slides for the modules that explicitly reference how sustainability topics will be integrated.

b. Embed specific activities involving the SDGs in a given theme, and include students in identifying these. See below for suggestions, and visit the Teaching resources in this toolkit for more options.

Appendix:

A. Outcome I.2 (programme level mapping)

B. Outcome II.5 (module level mapping) – same as above, but instead of the modules in individual lines, themes delivered within the module can be used to make sure the themes are mapped directly to SDGs.

C. II.6.b – Specific activities

Activity 1: Best carried out at the start of the module and then repeated near the end of the module to compare students perception and learning. Split students into groups of 3-4, at the start of the module use the module template (attached as a resource) to clearly outline the ILOs. Then present the SDGs and ask students to spend no more than 5 min identifying the top 3 SDGs they believe the material delivered in the module will enable them to address. Justify the selection. Can either feed back or exchange ideas with the group to their right. Capture these SDGs for comparison of the repeat exercise towards the end of the module. How has the perception of the group changed following the delivery of the module and why?
Activity 2: Variation on the above activity – student groups to arrange the SDGs in a pyramid with the most relevant ones at the top, capture the picture and return to it later in module delivery
Activity 3: Suitable particularly for the earlier stages. Use https://go-goals.org/ to increase the general awareness of SDGs.
Activity 4: The coursework geared to the SDGs, with each student choosing a goal of their choice and developing a webmap to demonstrate the role of module-relevant data and analysis in tackling that goal.

Learning and teaching notes: 

This resource describes a coursework aligned to three key pedagogical approaches of ESD. (1) It positions the students as autonomous learners (learner-centred); (2) who are engaged in action and reflect on their experiences (action-oriented); and (3) empowers and challenges learners to alter their worldviews (transformative learning). Specifically, it requires students to engage in collaborative peer learning (Einfalt, Alford, and Theobald 2022; UNESCO 2021). The coursework is an innovative Assessment for Learning” (AfL) (Sambell, McDowell, and Montgomery, 2013) internationalisation at home (Universities UK, 2021) group and individual assessment for first-year civil & environmental engineers enrolled on two programmes (BEng (Hons) / MEng Civil Engineering & BEng (Hons) / MEng Civil & Environmental Engineering). However, the coursework could easily be adapted to any other engineering discipline by shifting the theme of the example subjects. With a modification on the subjects, there is potential to consider engineering components / artifacts / structures, such as naval vessels / aeroplanes / cars, and a wide number of products and components that have particular significance to a country (i.e., Swiss Army Knife).

Learners have the opportunity to:

Engage in collaborative peer learning and socialise with students from different countries.
Gain knowledge related to the design and construction of civil engineering buildings and structures.
Develop a ‘global engineering mindset.’

Teachers have the opportunity to:

Promote, recognise, and reward intercultural engagement and the development of intercultural competence (IC).
Raise student awareness of an engineer’s role in the UNSDGs.

Learning and teaching resources: 

Rationale:

There have been several calls to educate the global engineer through imbedding people and planet issues in the engineering curriculum (Bourn and Neal, 2008; Grandin and Hirleman 2009). Students should be accepting of this practice given that prospective freshers are ‘positively attracted by the possibility of learning alongside people from the rest of the world’ (Higher Education Policy Unit, 2015:4). Correspondingly, ‘international students often report that an important reason in their decision to study abroad is a desire to learn about the host country and to meet people from other cultures’ (Scudamore, 2013:14). Michel (2010:358) defines this ‘cultural mobility’ as ‘sharing views (or life) with people from other cultures, for better understanding that the world is not based on a unique, linear thought’.

Coursework brief summary extracted from the complete brief:

Civil Engineering is an expansive industry with projects across many subdisciplines (i.e. Bridges, Buildings, Coastal & Marine, Environmental, Geotechnical, Highways, Power including Renewables. In a group students are required to consult with an international mentor and investigate civil engineering (buildings & structures) in the mentor’s home country. Each student should select a different example. These can be historical projects, current projects or projects planned for the future, particularly those projects that are addressing the climate emergency. Students will then complete two tasks:

Task 1: Group International Poster (10% weighting)
Task 2: Individual reflective Report (10% weighting)

Time frame and structure:

1. Opening lecture covering:

a. Reasoning for coursework with reference to transnational engineering employers and examples of international engineering projects and work across national boundaries.

b. Links between engineering, people, and planet through the example of biomimicry in civil engineering design (Hayes, Desha, & Baumeister, 2020) or nature-based solutions in the context of civil engineering technology (Cassina and Matthews ,2021).

c. Existence of non-governmental organisations (NGOs) such as RedR UK (2023) Water Aid (2023) and Bridges to Prosperity (2023).

d. The use of corporate social responsibility (CSR) to address problematic issues such as human rights abuses (Human Rights Watch, 2006) and bribery and corruption (Stansbury and Stansbury) in global engineering projects.

2. Assign students to groups:

a. Identify international mentors. After checking the module registration list, identify international students and invite them to become a mentor to their peers. Seek not to be coercive and explain that it is a voluntary role and to say no will have no impact on their studies. In our experience, less than a handful have turned down this opportunity. The peer international students are then used as foundation members to build each group of four first-year students. Additional international student mentors can be sourced from outside the module to assist each group.

b. Establish team contracts and group work processes using the Carnegie Mellon Group Working Evaluation document

3. Allow for group work time throughout the module to complete the tasks (full description can be found in the complete brief).

Assessment criteria:

The coursework constitutes a 20% weighting of a 10-Credit elective module- Engineering & Society. The submission has two assessed components: Task 1) a group international poster with annotated sketches of buildings & structures (10% weighting); and Task 2) A short individual reflective writing report (10% weighting) that seeks to ascertain the students experience of engaging in a collaborative peer activity (process), and their views on their poster (product). Vogel et al, (2023, 45) note that the use of posters is ‘well-suited to demonstrating a range of sustainability learning outcomes’. Whilst introducing reflective writing in a first-year engineering course has its challenges, it is recognised that reflective practice is an appropriate task for ESD- ‘The teaching approaches most associated with developing transformative sustainability values stimulate critical reflection and self-reflection’ (Vogel et al, 2023, 6).

Each task has its own assessment criteria and process. Assessment details can be found in the complete coursework brief.

Teaching reflection:

The coursework has been undertaken by nine cohorts of first-year undergraduate civil engineers (N=738) over seven academic sessions between 2015-2024. To date this has involved (N=147) mentors, representing sixty nationalities. Between 2015-2024 the international mentors have been first-year peers (N=67); senior year undergraduate & post-graduate students undertaking studies in the department (N=58) and visiting ERASMUS & International students (N =22) enrolled on programmes within the department.

Whilst the aim for the original coursework aligns with ESD (‘ESD is also an education in values, aiming to transform students’ worldviews, and build their capacity to alter wider society’ -Vogel et al ,2023:21) the reflective reports indicate that the students’ IC gain was at a perfunctory level. Whilst there were references to ‘a sense of belonging, ‘pride in representing my country’, ‘developing friendships’, ‘international mentors’ enthusiasm’ this narrative indicates a more generic learning gain that is known to help students acquire dispositions to stay and to succeed at university (Harding and Thompson, 2011). The coursework brief fell short of addressing the call ‘to transform engineering education curricula and learning approaches to meet the challenges of the SDGs’ (UNESCO,2021:125). Indeed, as a provocateur pedagogy, ‘ESD recognises that education in its current form is unsustainable and requires radical change’ (Vogel et al ,2023, 4).

Given the above it is clear that the coursework requirement for peer collaboration and reflective practice aligns to three of the eight key competencies (collaboration, self-awareness, critical thinking) for sustainability (UNESCO, 2017:10). Scudamore (2013:26) notes the importance of these competencies when she refers to engaging home and international students in dialogue- ‘the inevitable misunderstandings, which demand patience and tolerance to overcome, form an essential part of the learning process for all involved’. Moreover, Beagon et al (2023) have acknowledged the importance of interpersonal competencies to prepare engineering graduates for the challenges of the SDG’s. Thus, the revised coursework brief prompts students to journey ‘through the mirror’ and to reflect on how gaining IC can assist their knowledge of, and actions towards the SDG’s.

Who is this article for? This article should be read by educators at all levels of higher education looking to embed and integrate sustainability into curriculum design. It may also be of interest for students practising lifelong learning to articulate and explore how their learning translates into competency development as they embark on their careers.

Premise:

Today we know that how we engineer is changing – and this change is happening at a quicker pace than in previous decades. The decisions engineers make throughout their careers shape the world we all inhabit. Consequently, the education of engineers has a profound impact on society. Ensuring our degrees are up to date is of pressing importance to prepare all future practitioners and professionals. Arguably, it is especially important for engineers to act sustainably, ethically and equitably.

How do engineers understand their roles when sustainability becomes a key driver in the context of their work? What does sustainability look like in learning journeys, and how can it be incorporated into assessments? This article does not advocate for simply adding ‘sustainability’ to degrees; rather, it encourages the connection between sustainability competencies and engineering assessments.

Developing 21st-century engineers

Choosing to become an engineer is a great way to be useful to society. Studying an engineering degree can develop what people can do (skills), what they know (knowledge) and how they think (mindset), as well as open up a diverse range of career opportunities.

The path to becoming an engineer can start at university (though there are other routes in). Weaving in a focus on globally responsible engineering throughout a degree course is about embracing the need to develop a broader set of competencies in engineers and expand the types of projects they practise on during their degree to reflect the problems they may encounter during their career.

This doesn’t mean that engineering degrees as they are aren’t valuable or useful. It’s about strengthening the building blocks of degrees to ensure that 21st-century engineers have space to play their role in addressing 21st-century societal challenges. These building blocks are what learning outcomes are prioritised, what pedagogies are used, the types of projects students work on, who they work with and the way we assess learning. All of these elements can be aggregated to develop competence in sustainable engineering practice.

What are sustainability competency frameworks saying?

There are many frameworks exploring what are the competencies most needed today (such as UNESCO Education for Sustainable Development competencies, EU GreenComp, Inner Development Goals). Many frameworks are calling for similar things that allow us to shift focus, attention and energy onto how to truly develop a person over the three to five plus years of experience they might gain at university.

By designing education to meet learning outcomes, you build and evidence a range of competencies, including developing the mindsets of learners. Practically, it is the use of different competency frameworks, and the associated updates to learning outcomes, and how we deliver education and assessment that really matters. The table below, in the second column, synthesises various competency frameworks to clearly articulate what it means a learner can then do. Rather than argue different frameworks, focusing on what a student can do as a result is really key.

Figure 1. Competencies for sustainable development in Advance HE and QAA (2021) and UNESCO Education for Sustainable Development (2017).

By reading through this table, you can see that this is more than just about ‘sustainability’ – these are useful things for a person to be able to do. Ask yourself, what if we don’t develop these in our graduates? Will they be better or worse off?

Graduates can then build on this learning they have had at university to continue to develop as engineers working in practice. The Global Responsibility Competency Compass for example points practitioners to the capabilities needed to stay relevant and provides practical ways to develop themselves. It is made up of 12 competencies and is organised around the four guiding principles of global responsibility – Responsible, Purposeful, Inclusive and Regenerative.

What needs to shift in engineering education?

The shifts required to the building blocks of an engineering degree are:

To adapt and repurpose learning outcomes.
To integrate more real-world complexity within project briefs.
To be excellent at active pedagogies and mindset development.
To ensure authentic assessment.
To maximise cross-disciplinary experience and expertise.

All of the above need to be designed with mechanisms that work at scale. Let’s spotlight two of these shifts, ‘to adapt and repurpose learning outcomes’ and ‘to integrate authentic assessment’ so we can see how sustainability competence relates.

Adapt and repurpose learning outcomes.

We can build on what is already working well within a degree to bring about positive changes. Many degrees exhibit strengths in their learning outcomes such as, developing the ability to understand a concept or a problem and apply that understanding through a disciplinary lens focused on simple/complicated problems. However, it is crucial to maintain a balance between addressing straightforward problems and tackling more complex ones that encourage learners to be curious and inquisitive.

For example, a simple problem (where the problem and solution are known) may involve ‘calculating the output of a solar panel in a community’. A complex problem (where the problem and solution are unknown) may involve ‘how to improve a community’s livelihood and environmental systems, which may involve exploring the interconnectedness, challenges and opportunities that may exist in the system.

Enhancing the learning experience by allowing students to investigate and examine a context for ideas to emerge is more reflective of real-world practice. Success is not solely measured by learners accurately completing a set of problem sets; rather, it lies in their ability to apply concepts in a way that creates a better, more sustainable system.

See how this rebalancing is represented in the visual below:

Figure 2. Rebalancing learning within degrees to be relevant to the future we face. Source: Engineers Without Borders UK.

Keeping up to date and meeting accreditation standards is another important consideration. Relating the intended learning outcomes to the latest language associated with accreditation requirements, such as AHEP4 (UK), ABET (US) or ECSA (SA), doesn’t mean you have to just add more in. You can adapt what you’ve already got for a new purpose and context. For instance, the Engineering for One Planet framework’s 93 (46 Core and 46 Advanced) essential sustainability-focused learning outcomes that hundreds of academics, engineering professionals, and other key stakeholders have identified as necessary for preparing all graduating engineers — regardless of subdiscipline — with the skills, knowledge, and understanding to protect and improve our planet and our lives. These outcomes have also been mapped to AHEP4.

Integrate authentic assessment:

It is important that intended learning outcomes and assessment methods are aligned so that they reinforce each other and lead to the desired competency development. An important distinction exists between assessment of learning and assessment as or for learning:

Assessment OF learning e.g. traditional methods of assessment of student learning against learning outcomes and standards that typically measure students’ knowledge-based learning.
Assessment AS/FOR learning e.g. reflective and performance-based (e.g. self-assessments, peer assessments and feedback from educators using reflective journals or portfolios) where the learning journey is part of the assessment process that captures learners’ insights and critical thinking, and empowers learners to identify possibilities for improvement.

Assessment should incorporate a mix of methods when evaluating aspects like sustainability, to bring in authenticity which strengthens the integrity of the assessment process and mirrors how engineers work in practice. For example, University College London and Kings College London both recognise that critical evaluation, interpretation, analysis, and judgement are all key skills which will become more and more important, and making assessment rubrics more accessible for students and educators. Authentic assessment can mirror professional practices, such as having learners assessed within design reviews, or asking students to develop a portfolio across modules.

Engineers Without Borders UK | Assessing competencies through design challenges:

Below is an example of what Engineers Without Borders UK has done to translate competencies into assessment through our educational offerings. The Engineering for People Design Challenge (embedded in-curriculum focuses on placing the community context at the heart of working through real-world project-based learning experiences) and Reshaping Engineering (a co-curricular voluntary design month to explore how to make the engineering sector more globally responsible). The competencies in the Global Responsibility Competency Compass are aligned and evidenced through the learning outcomes and assessment process in both challenges.

Please note – the Global Responsibility Competency Compass points practitioners to the capabilities needed to stay relevant and provides practical ways to develop themselves.

For educators looking to keep curriculum and learning outcomes relevant, the Compass provides a useful framing to inform learning outcomes throughout the curriculum that encourages lifelong learning for emerging engineers or supports the reskilling of engineering professionals (to pursue topics that may have been absent from the user’s formal education), and constantly evolving their competency through educational activities.

For students, this may be of interest as you begin your journey as future engineering professionals and student members of professional engineering institutions exploring what continued professional development you wish to pursue in your careers.

See below an example of the logic behind translating competencies acquired by participants to assessment during the design challenges.

Figure 3. Example of the logic behind translating the Global Responsibility Competency Compass to assessment during the design challenges. Source: Engineers Without Borders UK.

1. The Competencies developed through the educational offering are orientated around the Global Responsibility Competency Compass to align with the learning journey from undergraduate to practising globally responsible individuals in learners’ future careers.
2. We then align learning outcomes to the competency and purpose of the design challenge using simple and concise language.

a. Useful resources that were used to help frame, align and iterate the learning outcomes and marking criteria are shared at the end of this article.

1. The Marking Criteria draws on the assessment methods previously mentioned under ‘Assessment OF’ and ‘Assessment AS/FOR’ while aligning to the context of intended learning i.e. design focussed, individual journals reflecting on the learning journey, and collaborating in teams.
2. We frame and align key action words from Competency to learning outcome to marking criteria using Bloom’s taxonomy (in Figure 2) to scale appropriately, the context of learning and what the intended outcome of learning/area of assessment would be.

Conclusions:

How your students think matters. How they engage in critical conversations matters. What they value matters. How we educate engineers matters.

These may feel like daunting shifts to make but developing people to navigate our future is important for them, and us. Sustainability competencies are actually about competencies that are useful – the label ‘sustainability’ may or may not help but it’s the underlying concepts that matters most. The interventions that we make to instil these competencies in the learning journeys of future engineers are required – so degrees can be continuously improved and will be valuable over the long term. Making assessment mirror real practice helps with life-long learning. That’s useful in general, not just about sustainability. This is a major opportunity to attract more people into engineering, keep them and enable them to be part of addressing urgent 21st century challenges.

“Sustainability is more than a word or concept, it is actually a culture, and if we aim to see it mirrored in the near future, what better way exists than that of planting it in the young hearts of today knowing they are the leaders of the tomorrow we are not guaranteed of? It is possible.”

Useful resources:

There are some excellent resources out there that help us understand and articulate what sustainability competencies and learning outcomes look like, and how to embed them into teaching, learning and assessment. Some of them were used in the example above. Here are some resources that we have found useful in translating the competencies in the Compass into learning outcomes in our educational offerings:

Bloom’s Taxonomy: a hierarchical model that categorises learning objectives into levels of complexity is a useful model to explore the proficiency of learning outcomes (and used in many of the resources in this list). You can use the verbs outlined in Bloom’s Taxonomy to modify or scale up the proficiency of your learning outcomes within the context of the programme and accreditation requirements. This is useful if you are unable to replace or introduce new learning outcomes into your module or programme.

Educational level: Beginner / intermediate. Learners are required to have basic (level 2) science knowledge, and ability to populate a mathematical formula and use units correctly.

Learning and teaching notes:

This activity allows students to consider the dilemmas around providing housing that is cheap to heat as well as cheap to buy or rent. It starts with researching these issues using contemporary news and policy, continues with an in-depth study of insulation, together with calculations of U values, heat energy and indicative costs.

Learners have the opportunity to:

solve given technical tasks relating to insulation properties (AHEP: SM1m)
assess the heating requirement of a given house (AHEP: EA1m)
research a contemporary issue using websites and guided material

Teachers have the opportunity to:

introduce concepts related to heating and energy theory
develop learners’ mathematical skills in a practical context.
Structure a task around a sustainability issue and recognise the economic, social and cultural issues, as well as the technical ones

Supporting resources:

To prepare for these activities, teachers may want to explain, or assign students to pre-read articles relating to heating a house with respect to:

Specific heat capacity
Energy

Introduction to the activity (teacher):

Provide the stimulus to motivate the students by considering the dilemma: How do we provide affordable housing whilst minimising heating requirement? There are not enough homes in the UK for everyone who needs one. Some of the houses we do have are expensive to run, poorly maintained and cost a fortune in rent. How do we get the housing builders to provide enough affordable, cheap to run housing for the population?

One possible solution is adopting Passivhaus standards. The Passivhaus is a building that conforms to a standard around heating requirements that ensures the insulation (U value) of the building material, including doors, windows and floors, prevents heat leaving the building so that a minimum heating requirement is needed. If all houses conformed to Passivhaus standards, the running costs for the householder would be reduced.

Teaching schedule:

Provide stimulus by highlighting the housing crisis in the UK:

McMullan, L. et al. (2021) UK housing crisis: How did owning a home become unaffordable?, The Guardian. (Accessed: 19 February 2024).

Students can then research and find the answers to the following questions using the following links, or other websites:

What is passivhaus? (no date) Passivhaus Trust. (Accessed: 19 February 2024).

Housing crisis in the UK:

How many houses are needed, now and in the future?

How many people currently live in temporary accommodation, and is this number expected to change?

Are developers required to add affordable housing to their plot? Should they be?

People requiring affordable housing for rent are likely to be among the poorest, so how many people are in ‘fuel poverty’?

Affordable housing needs to be built in such a way as to minimise the heat needed to keep the house warm. What categories of people are especially vulnerable?

What features/standards must a Passivhaus satisfy? How does this standard address the problems?

Students can work in groups to work on the extent of the problem from the bullet points provided. This activity can be used to develop design skills (Define the problem)

1. Get the engineering knowledge about preventing heat leaving a house:

If you can prevent heat leaving, you won’t need to add any more, it will stay at the same temperature. Related engineering concepts are:

Newtons law of cooling
U values
Heat transfer

2. Task:

a. Start with a standard footprint of a three-bed semi, from local estate agents. Make some assumptions about inside and outside temperatures, height of ceilings and any other values that may be needed.

b. Use the U value table to calculate the heat loss for this house (in Watts). The excel table has been pre-populated or you can do this as a group

With uninsulated materials (single glazing, empty cavity wall, no loft insulation.
With standard insulation (double glazing, loft insulation, cavity wall insulation.
If Passivhaus standards were used to build the house.

c. Costs

Find the typical cost for heating per kWh
Compare the costs for replacing the heat lost.

d. Final synoptic activity

Passivhaus costs a lot more than standard new build. How do housebuilders afford it?
Provide examples of the cost of building a Passivhaus standard building materials and reduced heating bills.
Suggest some ‘carrots’ and ‘sticks’ that could be used to make sure housing in the UK is affordable to rent/buy and run.

3. Assessment:

The spreadsheet can be assessed, and the students could write a report giving facts and figures comparing different levels of insulation and the effects on running costs.

Premise:

Projects, and thus project-based learning, offer valuable opportunities for integrating sustainability education into engineering curricula by promoting active, experiential learning through critical and creative thinking within problem-solving endeavours and addressing complex real-world challenges. Engaging in projects can have a lasting impact on students’ understanding and retention of knowledge. By working on projects related to sustainability, students are likely to internalise key concepts and develop a commitment to incorporating sustainable practices into their future engineering endeavours.

Building a brief:

Project briefs are a powerful tool for integrating sustainability into engineering education through project-based learning. They set the tone, define the scope, and provide the parameters for students to consider sustainability in their engineering projects, ensuring that future engineers develop the knowledge, skills, and mindset needed to address the complex challenges of sustainability.

To ensure sustainability has a central and/or clear role within an engineering project, consider the following as you develop the brief:

1. Sustainability as part of goals, objectives, and requirements. By explicitly including sustainability objectives in the project brief, educators communicate the importance of considering environmental, social, and economic factors in the engineering design and implementation process. This sets the stage for students to integrate sustainability principles into their project work.

2. Context: Briefs should always include the context of the project so that students understand the importance of place and people to an engineered solution. Below are aspects of the context to consider and provide:

What is the central problem for the project?
Where is the problem/project located? What data will be given to students to describe the context of the problem? Why is the context important and how does it relate to expectations of solving of the problem or the project solution
Who are the people directly impacted by the scenario and central to the context? What is the problem that they face and why? How are they associated with the project and why do they need to be considered?
When in time does this scenario/context exist? How does the data or information re. the context support the time of the scenario?

3. Stakeholders: Sustainability is intertwined with the interests and needs of various stakeholders. Project briefs can include considerations for stakeholder engagement, prompting students to identify and address the concerns of different groups affected by the project. This reinforces the importance of community involvement and social responsibility in engineering projects. Below are aspects of the stakeholders to consider and provide:

Who are the main stakeholders (i.e. users) and why are they important to the context? (see above) What are their needs and what are their power positions
Who else should be considered stakeholders in the project? How do they influence the project by their needs, interest and power situations?
Have you considered the earth and its non-human stakeholders, its inhabitants or its landscape?
Do you want to provide this information to the students or is this part of the work you want them to do within the project?

4. Ethical decision-making: Including ethical considerations related to sustainability in the project brief guides students in making ethical decisions throughout the project lifecycle. The Ethics Toolkit can provide guidance in how to embed ethical considerations such as:

Explicitly state ethical expectations and frame decisions as having ethical components.
Prompt and encourage students to think critically about the consequences of their engineering choices on society, the environment, and future generations.

5. Knowns and unknowns: Considering both knowns and unknowns is essential for defining the project scope. Knowing what is already understood and what remains uncertain allows students to set realistic and achievable project goals. Below are aspects of considering the knowns and unknowns aspects of a project brief to consider and provide:

What key information needs to be provided to the students to address the problem given?
What is it that you want the students to do for themselves in the early part of the project – i.e. research and investigation and then in the process of their problem solving and prototyping/testing and making?

6. Engineering design process and skills development: The Project Brief should support how the educator wants to guide students through the engineering design cycle, equipping them with the skills, knowledge, and mindset needed for successful problem-solving. Below are aspects of the engineering design process and skills development to consider and provide:

What process will the students follow in order to come to a final output or problem solution? What result is required of the students (i.e. are they just coming up with concepts or ideas? Do they need to justify and thus technical argue their chosen concept? Do they need to design, build/make and test a prototype or model to show their design and building/making skills as well? Do they need to critically analyse it using criteria based on proof of concept or sustainability goals – ie. It is desirable? Viable? Responsible? Feasible?)
What skills should students be developing through the project? Some possibilities are (depending on how far they expect students to complete the solution), however the sustainability competencies are relevant here too:

a. Research – investigate,

b. Creative thinking – divergent and convergent thinking in different parts of the process of engineering design,

c. Critical thinking – innovation model analysis or other critical thinking tools,

d. Decision making – steps taken to move the project forward, justifying the decision making via evidence,

e. Communication, collaboration, negotiation, presentation,

f. Anticipatory thinking – responsible innovation model AREA, asking in the concept stages (which ideas could go wrong because of a double use, or perhaps thinking of what could go wrong?),

g. Systems thinking.

7. Solution and impact: Students will need to demonstrate that they have met the brief and can demonstrate that they understand the impact of their chosen solution. Here it would need to be clear what the students need to produce and how long it is expected to take them. Other considerations when designing the project brief to include are:

Is the brief for a module or a short activity? What is the ideal number of students in a team? Is it disciplinary-based or interdisciplinary (and in this case – which disciplines would be encouraged to be included).
We would want the students to understand and discuss the trade-offs that they had to consider in their solution.

Important considerations for embedding sustainability into projects:

1. Competences or content?

Embedding and/or developing competences is a normal part of project work. When seen as a set of competences sustainability is crosscutting in the same way as other HE agendas such as employability, global citizenship, decolonisation and EDI. See the Global Responsibility competency compass for an example of how competencies can be developed for engineering practice.

Embedding sustainability content often requires additional material, even if it is only in adapting one of the project phases/outcomes to encourage students to think through sustainable practice. For more guidance on how to adapt learning outcomes, see the Engineering for One Planet Framework (aligned to AHEP4).

2. Was any content added or adapted?

Was any content adapted to include sustainability awareness?

– What form of content, seminars, readings, lectures, tutorials, student activity

Were learning objectives changed?

Did you have to remove material to fit in the new or adapted content?

Were assessments changed?

3. Competencies

UNESCO has identified eight competencies that encompass the behaviours, attitudes, values and knowledge which facilitate safeguarding the future. These together with the SDGs provide a way of identifying activities and learning that can be embedded in different disciplinary curricula and courses. For more information on assessing competences, see this guidance article.

Did you map the competences that you already support before changing anything?
What kind of activities did you add to support the development of the competences you wish to target?
Did you explain to the students that these were the competences that you were targeting and that they are considered necessary for all who go on to work and live in a warming world?

SDG 7: Affordable and Clean Energy – Understand the global emphasis on clean energy and its implications
African Development Bank: Off-Grid Revolution
The World Bank : Mini Grids in Africa
International Energy Agency : Energy Access Outlook: from Poverty to Prosperity
James P Dunlop; Photovoltaic systems; ISBN: 978-0826913081; American Technical Publishers. Photovoltaic Systems is a comprehensive guide to the design and installation of several types of residential and commercial PV systems.
DGS; Planning and installing photovoltaic systems: A guide for installers, architects and engineers; ISBN: 978-1849713436; Planning and installing series.

In accordance with a report from the International Energy Agency (IEA) and statistics provided by the World Bank, approximately 633 million individuals in Africa currently lack access to electricity. This stark reality has significant implications for the remote villages across the continent, where challenges related to energy access persistently impact various aspects of daily life and stall social and economic development. In response to this critical issue, the deployment of off-grid renewable solutions emerges as a promising and sustainable alternative. Such solutions have the potential to not only address the pressing energy gap but also to catalyse development in isolated regions.

Situated in one of Egypt’s most breathtaking desert landscapes, Siwa holds a position of immense natural heritage importance within Egypt and on a global scale. The region is home to highly endangered species, some of which have restricted distributions found only in Siwa Oasis. Classified as a remote area, a particular community in Siwa Oasis currently relies predominantly on diesel generators for its power needs, as it remains disconnected from the national grid. Moreover, extending the national grid to this location is deemed economically and environmentally impractical, given the long distances and rugged terrain.

Despite these challenges, Siwa Oasis possesses abundant renewable resources that can serve as the foundation for implementing a reliable, economical, and sustainable energy source. Recognising the environmental significance of the area, the Egyptian Environmental Affairs Agency (EEAA) declared Siwa Oasis as a protected area in 2002.

Part one: Household energy for Siwa Oasis

Imagine being an electrical engineer tasked with developing an off-grid, sustainable power solution for Siwa Oasis village. Your goal is to develop a solution that not only addresses the power needs but also is sustainable, ethical, and has a positive impact on the community. The following data may help in developing your solution.

Data on Household Energy for Siwa Oasis:

Activities:

Analyse typical household appliances and their power consumption (lighting, refrigeration, pressing Iron).
Simulate daily energy usage patterns using smart meter data.
Identify peak usage times and propose strategies for energy conservation (example LED bulbs, etc)
Calculate appliance power consumption and estimate electricity costs.
Discussion:

a. How does this situation relate to SDG 7, and why is it essential for sustainable development?

b. What are the primary and secondary challenges of implementing off-grid solutions in remote villages?

Part two: Power supply options

Electricity supply in Siwa Oasis is mainly depends on Diesel Generators, 4 MAN Diesel Generators of 21 MW which are going to be wasted in four years, 2 CAT Diesel Generators of 5.2 MW and 1 MAN Diesel Generator 4 MW for emergency. Compare and contrast various power supply options for the household (renewable vs. fossil fuel).

Renewable: Focus on solar PV systems, including hands-on activities like solar panel power output measurements and battery sizing calculations.
Fossil fuel: Briefly discuss diesel generators and their environmental impact.

The Siwa Oasis community is divided over the choice of power supply options for their households. On one hand, there is a group advocating for a complete shift to renewable energy, emphasising the environmental benefits and long-term sustainability of solar PV systems. On the other hand, there is a faction arguing to continue relying on the existing diesel generators, citing concerns about the reliability and initial costs associated with solar power. The community must decide which power supply option aligns with their values, priorities, and long-term goals for sustainability and energy independence. This decision will not only impact their day-to-day lives but also shape the future of energy use in Siwa Oasis.

Optional STOP for questions and activities:

Debate: Is it ethical to impose new technologies on communities, even if it’s for perceived improvement of living conditions?
Discussion: How can engineers ensure the sustainability (environmental and operational) of off-grid solutions in remote locations?
Activities: Students to design a basic solar PV system for the household, considering factors like energy demand, solar resource availability, and budget constraints.

Part three: Community mini-grid via harnessing the desert sun

Mini-grid systems (sometimes referred to as micro-grids) generally serve several buildings or entire communities. The abundant sunshine in Siwa community makes it ideal for solar photovoltaic (PV) systems and based on the load demand of the community, a solar PV mini grid solution will work perfectly.

Electrical components of a typical PV system can be classified into DC and AC.

DC components: The electrical connection of solar modules to the inverter constitutes the DC part of a PV installation. Its design requires particular care and reliable components, as there is a risk of significant accidents with high DC voltages and currents, especially due to electric arcs.

The key DC components are:

PV cables and connectors: PV modules are usually delivered with a junction box and pre-assembled cables with single-contact electrical connectors. They enable easy interconnection of individual modules in strings. Solar cables are made of copper or aluminum (more cost-efficient).
Combiner boxes: Here, incoming strings are connected in parallel, and the resulting current is channeled through an output terminal to the inverter. A combiner box usually contains all required protection devices, disconnectors, and measuring equipment for string monitoring.

AC components: The equipment installed on the AC side of the inverter depends on the size and voltage class of the grid connection (low-voltage (LV), medium-voltage (MV), or high-voltage (HV) grid). Utility-scale PV plants usually require the following equipment:

Transformers, to increase the inverter output voltage to the grid voltage level
AC cables, buried
Circuit breakers, switchgears, and protection devices, for large PV plants (MV/HV connection)
Electricity meters

Activities:

Research and discuss the safety precautions and regulations for working with DC systems.
Analyse the DC components of a typical PV system, including cables, connectors, and combiner boxes.
Calculate the voltage and current levels at different points in the DC circuit based on the system design.
Investigate the concept of power factor and its significance in grid stability and energy bills.
Analyse the power factor of common household appliances and discuss its impact on the mini-grid.
Propose strategies to improve the overall power factor of the mini-grid, such as using capacitors or choosing energy-efficient appliances.

Learning and teaching notes:

This case study provides students an opportunity to explore the role of hydrogen fuel in the aviation industry. Considerable investments have been made in researching and developing hydrogen as a potential clean and sustainable energy source, particularly for hydrogen-powered aircraft. Despite the potential for hydrogen to be a green and clean fuel there are lingering questions over the long-term sustainability of hydrogen and whether technological advancements can progress rapidly enough to significantly reduce global carbon dioxide emissions. The debate around this issue is rich with diverse perspectives and a variety of interests to consider. Through this case study, students will apply their engineering expertise to navigate this complex problem and examine the competing interests involved.

This case is presented in parts, each focusing on a different sustainability issue, and with most parts incorporating technical content. Parts may be used in isolation, or may be used to build up the complexity of the case throughout a series of lessons.

Learners have the opportunity to:

Understand the principles of hydrogen production, storage, and emissions in the context of aviation.
Assess the environmental, economic, and social impacts of adopting hydrogen technology in the aviation industry.
Develop skills in making estimates and assumptions in real-world engineering scenarios.

There are several free and available sources for this purpose (refer to the Hydrogen Fundamentals Resources above).

Introduction

“At Airbus, we believe hydrogen is one of the most promising decarbonisation technologies for aviation. This is why we consider hydrogen to be an important technology pathway to achieve our ambition of bringing a low-carbon commercial aircraft to market by 2035.” – Airbus, 2024

As indicated in the industry quote above, hydrogen is a growing area of research interest for aviation companies to decarbonise their fleet. In this case study, you are put in the role of working as an engineering consultant and your customer is a multinational aerospace corporation. They are keen to meet their government issued targets of reducing carbon emissions to reach net zero by 2050 and your consultancy team has been tasked with assessing the feasibility of powering a zero-emission aircraft using hydrogen. The key areas your customer is interested in are:

The feasibility of using green hydrogen as a fuel for zero-emission aviation;
The feasibility of storing hydrogen in a confined space like an aircraft;
Conducting a stakeholder analysis on the environmental impact of using hydrogen for aviation.

Part one: The aviation landscape

Air travel connects the world, enabling affordable and reliable mass transportation between continents. Despite massive advances in technology and infrastructure to produce more efficient aircraft and reduce passenger fuel consumption, carbon emissions have doubled since 2019 and are equivalent to 2.5 % of global CO2 emissions.

Activity: Discuss what renewable energy sources are you aware of that could be used for zero-emission aviation?

Your customer is interested in the feasibility of hydrogen for aviation fuel. However, there is a debate within the management team over the sustainability of hydrogen. As the lead engineering consultant, you must guide your customer in making an ethical and sustainable decision.

Hydrogen is a potential energy carrier which has a high energy content, making it a promising fuel for aviation. Green hydrogen is produced from water and is therefore potentially very clean. However, globally most hydrogen is currently made from fossil fuels with an associated carbon footprint. Naturally occurring as a gas, the low volumetric density makes it difficult to transport and add complications with storage and transportation.

Activity: From your understanding of hydrogen, what properties make it a promising fuel for aircraft? And what properties make it challenging?

Optional activity: Recap the key properties of hydrogen – particularly the low gas density and low boiling point which affect storage.

Part two: Hydrogen production

Hydrogen is naturally abundant but is often found combined with other elements in various forms such as hydrocarbons like methane (CH4) and water (H2O). Methods have been developed to extract hydrogen from these compounds. It is important to remember that hydrogen is an energy carrier and not an energy source; it must be generated from other primary energy sources (such as wind and solar) converting and storing energy in the form of hydrogen.

Research: What production methods of hydrogen are you aware of? Where does most of the world’s hydrogen come from currently?

The ideal scenario is to produce green hydrogen via electrolysis where water (H2O) is split using electricity into hydrogen (H2) and oxygen (O2). This makes green hydrogen potentially completely green and clean if the process uses electricity from renewable sources. The overall chemical reaction is shown below:

However, the use of water—a critical resource—as a feedstock for green hydrogen, especially in aviation, raises significant ethical concerns. Your customer’s management team is divided on the potential impact of this practice on global water scarcity, which has been exacerbated by climate change. You have been tasked with assessing the feasibility of using green hydrogen in aviation for your client. Your customer has chosen their London to New York route (3,500 nmi), one of their most popular, as a test-case.

Activity: Estimate how much water a hydrogen plane would require for a journey of 5000 nmi (London to New York). Can you validate your findings with any external sources? Hint: How much water does it take to produce 1 kg of green hydrogen? Consider the chemical equation above.

Activity: Consider scaling this up and estimate how much water the entire UK aviation fleet would require in one year. Compare your value to the annual UK water consumption, would it be feasible to use this amount of water for aviation?

Discussion: From your calculations and findings so far, discuss the practicality of using water for aviation fuel. Consider both the obstacles and opportunities involved in integrating green hydrogen in aviation and the specific challenges the aviation industry might face.

Despite its potential for green production, globally the majority of hydrogen is currently produced from fossil fuels – termed grey hydrogen. One of your team members has proposed using grey hydrogen as an interim solution to bridge the transition to green hydrogen, in order for the company to start developing the required hydrogen-related infrastructure at airports. They argue that carbon capture and storage technology could be used to reduce carbon emissions from grey hydrogen while still achieving the goal of decarbonisation. Hydrogen from fossil fuels with an additional carbon capture step is known as blue hydrogen.

However, this suggestion has sparked a heated debate within the management team. While acknowledging the potential to address the immediate concerns of generating enough hydrogen to establish the necessary infrastructure and procedures, many team members argued that it would be a contradictory approach. They highlighted the inherent contradiction of utilising fossil fuels, the primary driver of climate change, to achieve decarbonisation. They emphasised the importance of remaining consistent with the ultimate goal of transitioning away from fossil fuels altogether and reducing overall carbon emissions. Your expertise is now sought to weigh these options and advise the board on the best course of action.

Optional activity: Research the argument for and against using grey or blue hydrogen as an initial step in developing hydrogen infrastructure and procedures, as a means to eventually transition to green hydrogen. Contrast this with the strategy of directly implementing green hydrogen from the beginning. Split students into groups to address both sides of this debate.

Discussion: Deliberate on the merits and drawbacks of using grey or blue hydrogen to catalyse development of hydrogen aviation infrastructure. What would you recommend—prioritising green hydrogen development or starting with grey or blue hydrogen as a transitional step? How will you depict or visualise your recommendation to your client?

Part three: Hydrogen storage

Despite an impressive gravimetric energy density (the energy stored per unit mass of fuel) hydrogen has the lowest gas density and the second-lowest boiling point of all known chemical fuels. These unique properties pose challenges for storage and transportation, particularly in the constrained spaces of an aircraft.

Activity: Familiarise yourself with hydrogen storage methods. What hydrogen storage methods are you aware of? Thinking about an aviation context what would their advantages and disadvantages be?

As the lead engineering consultant, you have been tasked with providing expert advice on viable hydrogen storage options for aviation. Your customer has again chosen their London to New York route (3,500 nmi) as a test-case because it is one of their most popular, transatlantic routes. They want to know if hydrogen storage can be effectively managed for this route as it could set a precedent for wider adoption for their other long-haul flights. The plane journey from London to New York is estimated to require around 15,000 kg of hydrogen (or use the quantity estimated previously estimated in Part 2 – see Appendix for example).

Activity: Estimate the volume required to store the 15,000 kg of hydrogen as a compressed gas and as a liquid.

Discussion: How feasible are compressed gas and liquid hydrogen storage solutions? The space taken up by the fuel is one consideration but what other aspects are important to consider? How does this compare to the current storage solution for planes which use conventional jet fuel. Examples of topics to consider are: materials required for storage tanks, energy required to liquify or compress the hydrogen, practicality of hydrogen storage and transport to airports, location and distance between hydrogen generation and storage facilities, considerations of fuel leakage. When discussing encourage students to compare to the current state of the art, which is jet fuel.

Part four: Emissions and environmental impact

In Part four, we delve deeper into the environmental implications of using hydrogen as a fuel in aviation with a focus on emissions and their impacts across the lifecycle of a hydrogen plane. Aircraft can be powered using either direct combustion of hydrogen in gas turbines or by reacting hydrogen in a fuel cell to produce electricity that drives a propeller. As the lead engineering consultant, your customer has asked you to choose between hydrogen combustion in gas turbines or the reaction of hydrogen in fuel cells. The management team is divided on the environmental impacts of both methods, with some emphasising the technological readiness and efficiency of combustion and others advocating for the cleaner process of fuel cell reaction.

Activity: Research the main emissions associated with combustion of hydrogen and electrochemical reaction of hydrogen in fuel cells. Compare to the emissions associated with combustion of standard jet fuel. Students should consider not only CO2 emissions but also other pollutants such as NOx, SOx, and particulate matter.

Discussion: What are the implications of these emissions on air quality and climate change. Discuss the trade-offs between the different methods of utilising hydrogen in terms of the environmental impact. Compare to the current standard of jet fuel combustion.

Both combustion of hydrogen in an engine and reaction of hydrogen in a fuel cell will produce water as a by-product. The management team are concerned over the effect of using hydrogen on the formation of contrails. Contrails are clouds of water vapour produced by aircraft that have a potential contribution to global warming but the extent of their impact is uncertain.

Activity: Investigate how combustion (of both jet fuel and hydrogen) and fuel cell reactions contribute to contrail formation. What is the potential climactic effect of contrails?
Optional extension: How can manufacturers and airlines act to reduce water emissions and contrail formation – both for standard combustion of jet fuel and future hydrogen solutions?
Discussion: Based on your findings, which hydrogen propulsion technology would you recommend to the management team?

So far we have considered each aspect of the hydrogen debate in isolation. However, it is important to consider the overall environmental impact of these stages as a whole. Choices made at each stage of the hydrogen cycle – generation, storage, usage – will collectively impact the overall environmental impact and sustainability of using hydrogen as an aviation fuel and demonstrates how interconnected our decisions can be.

Activity: Assign students to groups based on the stage of a hydrogen lifecycle (generation, storage/transport, usage). Each group could research and discuss the potential emissions and environmental impacts associated with their assigned stage. Consider both direct and indirect emissions, like energy used in production processes or emissions related to infrastructure development. Principles such as life cycle assessment can be incorporated for a holistic view of hydrogen emissions.

Activity: After the individual group discussions, each group could present their findings and perspectives on their stage of the lifecycle. The whole class could then reflect on the overall environmental impacts of hydrogen in aviation. How do these impacts compare across different stages of the lifecycle? What are the trade-offs involved in choosing different types of hydrogen (green, blue, grey) and storage/transportation solutions?

Discussion: Conclude with a reflective discussion. Students bring together their findings on the life cycle stages of hydrogen and present their overall perspectives on the environmental sustainability of using hydrogen in aviation.

Part five: Hydrogen aviation stakeholders

Hydrogen aviation is an area with multiple stakeholders with conflicting priorities. Understanding the perspectives of these key players is important when considering the feasibility of hydrogen in the aviation sector.

Activity: Who are the key players in this scenario? What are their positions and perspectives? How can you use these perspectives to understand the complexities of the situation more fully?

Your consultancy firm is hosting a debate for the aviation industry in order to help them make a decision around hydrogen-based technologies. You have invited representatives from consumer groups, the UK government, Environmental NGOs, airlines, and aircraft manufacturers.

Activity: Take on the role of these key stakeholders, ensuring you understand their perspective and priorities. This could form part of a separate research exercise, or students can use the key points given below. Debate whether or not hydrogen fuel should be used to help the aviation sector reach net zero.

Stakeholder	Key priorities and considerations
Airline & Aerospace Manufacturer	Cost efficiency (fuel, labour, fleet maintenance) – recovering from pandemic. Passenger experience (commercial & freight). Develop & maintain global supply chains. Safety, compliance and operational reliability. Financial responsibility to employees and investors. Need government assurances before making big capital investments.
UK Government	Achieve net zero targets by 2050 Promote economic growth and job creation (still recovering from pandemic). Fund research and innovation to put their country’s technology ahead. Fund renewable infrastructure to encourage industry investment.
Environmental NGOs	Long-term employment for aviation sector. Demand a sustainable future for aviation to ensure this – right now, not in 50 years. Standards and targets for industry and government and accountability if not met. Some NGOs support drastic cuts to flying. Want to raise public awareness over sustainability of flying.
Consumer	Environmentally aware (understand the need to reduce carbon emissions). Also benefit greatly from flying (tourism, commercial shipping, etc.). Safety and reliability of aircraft & processes. Cost effectiveness – want affordable service

Appendix: Example calculations

There are multiple methods for approaching these calculations. The steps shown below are just one example for illustrative purposes.

Part two: Hydrogen production

Challenge: Estimate the volume of water required for a hydrogen-powered aircraft.

Assumptions around the hydrogen production process, aircraft, and fuel requirement can be given to students or researched as a separate task. In this example we assume:

All hydrogen is generated via electrolysis of fresh water with an efficiency of 100%.
A mid-size aircraft required with ~300 passenger capacity and flight range of ~3500 nmi (London to New York).
Flight energy requirement for a kerosene-fuelled jet is the same as a hydrogen-fuelled jet.

Example estimation:

1. Estimate the energy requirement for a mid-size jet

No current hydrogen-fuelled aircraft exists, so we can use a kerosene-fuelled analogue. Existing aircraft that meet the requirements include the Boeing 767 or 747. The energy requirement is then:

2. Estimate the hydrogen requirement

Assuming a hydrogen plane has the same fuel requirement:

3. Estimate the volume of water required

Assuming all hydrogen is produced from the electrolysis of water:

Electrolysis reaction:

For this reaction, we know one mole of water produces one mole of hydrogen. We need to calculate the moles for 20,000 kg of hydrogen:

With a 1:1 molar ratio, we can then calculate the mass of water:

This assumes an electrolyser efficiency of 100%. Typical efficiency values are under 80%, which would yield:

Challenge: Is it feasible to power the UK aviation fleet with water?

The total energy requirement for UK aviation can be given to students or set as a research task.

Estimation can follow a similar procedure to the above.

Multiple methods for validating and assessing the feasibility of this quantity of water. For example, the UK daily water consumption is 14 billion litres. The water requirement estimated above is < 1 % of this total daily water consumption, a finding supported by FlyZero.

Part three: Hydrogen storage

Challenge: Is it feasible to store 20,000 kg of hydrogen in an aircraft?

There are multiple methods of determining the feasibility of storage volume. As example is given below.

1. Determining the storage volume

The storage volume is dependent on the storage method used. Density values associated with different storage techniques can be research or given to students (included in Table 2). The storage volume required can be calculated from the mass of hydrogen and density of storage method, example in Table 2.

Table 2: Energy densities of various hydrogen storage methods

2. Determining available aircraft volume

A straightforward method is to compare the available volume on an aircraft with the hydrogen storage volume required. Aircraft volumes can be given or researched by students. Examples:

This assumes hydrogen tanks are integrated into an existing aircraft design. Liquid hydrogen can feasibly fit into an existing design, though actual volume will be larger due to space/constraint requirements and additional infrastructure (pipes, fittings, etc) for the tanks. Tank size can be compared to conventional kerosene tanks and a discussion encouraged over where in the plane hydrogen tanks would need to be (conventional liquid fuel storage is in the wings of aircraft, this is not possible for liquid storage tanks due to their shape and infrastructure storage is inside the fuselage). Another straightforward method for storage feasibility is modelling the hydrogen volume as a simple cylinder and comparing to the dimensions of a suitable aircraft.

Part one:

In the heart of an urban revitalisation project, the company CityScape Builders is embarking on a transformational journey to convert a neglected area into a vibrant urban centre which will be named ReviveRise District. This urban centre will mostly be formed by tall buildings.

Avery, the project manager at CityScape Builders, is under immense pressure to meet tight budget constraints and deadlines. Avery understands the project’s economic implications and the importance of delivering within the stipulated financial limits. However, the conflict arises when Rohan, a renowned environmental advocate and consultant, insists on prioritising sustainable construction practices to reduce the project’s embodied carbon. Rohan envisions a future where construction doesn’t come at the cost of the environment.

On the other side of the situation is Yuki, the CFO of CityScape Builders, who is concerned about the project’s bottom line. Yuki is wary of any actions that could escalate costs and understands that using low-embodied carbon materials often comes with a higher price tag.

In light of this situation, Avery proposes exploring different options of construction methods and materials that could be used in the design of their skyscrapers. Avery needs to do this quickly to avoid any delay, and therefore consider just the most important carbon-emitting aspects of the different options.

Optional STOP for questions and activities

Activity: research and calculate the embodied carbon of three different options that could be used to build one of the buildings at ReviveRise District. Make sure to consider all key aspects involved (e.g., project’s location, possible materials, etc.). Students can be encouraged to challenge the need to build skyscrapers.

Activity: conduct a cost-benefit analysis for the different options. What are the potential financial gains and losses? Students may want to consider the gains and losses from the perspectives of different stakeholders, such as engineers (e.g., construction programme savings) or quantity surveyors/cost consultants (e.g., security of supply material, insurance premiums).

Discussion: what are the key challenges in reducing embodied carbon in a construction project?

Discussion: how can the construction industry minimise activities that cause conflict between profitability and sustainability, and maximise activities that mutually-benefit sustainability and profitability?

Discussion: what are some strategies for convincing stakeholders of the long-term benefits of sustainable practices? In class, this can be done in different ways (e.g., class debate, elevator pitches).

Part two:

CityScape Builders is now embarking on a new challenge, ResilientCoast, a construction project located in a coastal area that is susceptible to climate change-related disasters. This region is economically disadvantaged and lacks the financial resources often found in more developed areas.

Micha, the resilience project manager at CityScape Builders, is tasked with ensuring the project’s durability in the face of disasters and the impacts of climate change. Micha’s primary concern is to create a resilient structure that can withstand extreme weather events but is equally dedicated to sustainability goals. To navigate this complex situation, Micha seeks guidance from Dr. Ravi, a climate scientist with expertise in coastal resiliency. Dr. Ravi is committed to finding innovative and sustainable solutions that simultaneously address the climate change impacts and reduce embodied carbon in construction.

In this scenario, Bao, the local community leader, also plays a crucial role. Bao advocates for jobs and economic development in the area, even though Bao is acutely aware of the inherent safety risks. Bao, too, understands that balancing these conflicting interests is a substantial challenge.

In this situation, Micha wonders how to construct safely in a vulnerable location while maintaining sustainability goals.

Optional STOP for questions and activities

Activity: investigate sustainable construction practices that enhance resilience. Create a list of methods and materials designed to withstand climate challenges,and evaluate their effectiveness to date.

Discussion: how can the construction industry minimise activities that cause conflict between safety and sustainability, and maximise activities that mutually-benefit sustainability and safety?

Discussion: what are the ethical considerations when constructing in areas prone to natural disasters and resource scarcity?

Discussion: what are some innovative solutions to promote safety and sustainability in construction projects in challenging environments, and what is their effectiveness in this situation?

Part three:

Robin and Samir are two independent sustainability consultants that are supporting the projects in ReviveRise District and ResilientCoast respectively. They are concerned that sustainability is just being assessed by embodied carbon and cost sustainability, and they believe that sustainability is a much broader concept than just those two indicators. Robin is the independent environmental consultant working with ReviveRise District officials and is responsible for assessing the broader environmental impacts of the construction project. Robin’s analysis spans beyond embodied carbon, considering local job creation, transportation effects, pollution, biodiversity, and other aspects of the project.

Samir, on the other hand, is a municipal board member of ResilientCoast. Samir’s role involves advocating for the local community while striving to ensure that sustainability efforts do not compromise the safety and resilience of the area. Samir’s responsibilities are more comprehensive than just economic considerations; they encompass the entire well-being of the community in the face of climate change.

Robin and Samir recognise the need for cross-city collaboration and information sharing, and they want to collaborate to ensure that the sustainability efforts of both projects do not create unintended burdens for their communities. They acknowledge that a comprehensive approach is necessary for analysing broader impacts, and to ensure both the success of the construction projects and the greater good of both communities. They believe in working collectively to find solutions that are not only sustainable but also beneficial to all stakeholders involved.

Optional STOP for questions and activities

Activity: work in pairs or small groups to analyse the holistic impacts of a construction project in their local area. Consider environmental, social, and economic factors and propose potential solutions. This can be supported by PESTLE and SWOT analysis, systems diagrams, or similar techniques.

Activity: envision a scenario where two cities, like in the case study, collaborate on a large construction project. Outline the key challenges, benefits, and potential strategies for success.

Discussion: how can different stakeholders work together to mitigate unintended burdens in construction projects?

Discussion: what are some effective strategies for cross-city collaboration on sustainability initiatives?

Discussion: how can construction projects contribute positively to their local communities while addressing environmental concerns?

The above questions and activities call for the involvement of cross-disciplinary teams, requiring expertise not only in engineering but also in planning, policy, and related fields. Ideally, in the classroom setting, students with diverse knowledge across these disciplines can be grouped together to enhance collaboration and address the tasks proposed. In cases where forming such groups is not feasible, the educator can assign specific roles such as engineer, planner, policymaker, etc., to individual students, ensuring a balanced representation of skills and perspectives.

Premise:

The role of engineering is to enhance the safety, health and welfare of all, while protecting the planet and reversing existing environmental damage by deploying engineering solutions that can meet urgent global and local needs across all sectors (Engineering Council, 2021). The socioeconomic and environmental problems are strongly linked and finding responsible solutions is of imminent urgency that requires a holistic interdisciplinary perspective.

Sustainability and Equality, Diversity and Inclusion (EDI):

Equality, diversity, and Inclusion are interlinked concepts that emphasise equal opportunities, the inclusion of underrepresented groups, and the benefits that derive from diverse perspectives within the engineering field. Because sustainability is a global phenomenon, achieving the objective of “providing for all” should be a priority for all engineering professionals to ensure solutions are developed that benefit all (Jordan et al., 2021). To address sustainability challenges, engineers need to keep in mind that some communities are disproportionately impacted by climate change and environmental harm. It is essential to empower these communities to create systematic change and advocate for themselves.

A strategic pedagogical approach to sustainability and EDI:

A variety of pedagogical strategies can be applied to incorporate diversity and inclusion perspectives into sustainability engineering. Rather than adopting an “add-on” approach to the existing programmes it is recommended to fully embed inclusive and sustainable perspectives in the existing curriculum. These perspectives should be incorporated following a learning path of the students, from the beginning of the programme in the engineering fundamentals, starting with raising awareness and understanding of these perspectives and gradually improving student knowledge supported by evidence and further to implementing and innovating in engineering practice and solutions. By the end of the programme, diversity and inclusion and sustainability perspectives should be fully incorporated into the attitude of the graduates so that they will consider this when approaching any engineering task. This approach would go hand-in-hand with incorporating an ethics perspective.

Some practical examples of implementation in the programme and gradually deepening student learning are:

1. Awareness and understanding:

a. Define sustainability and its relation to EDI.

b. Engage with practical examples in modules that can be considered and discussed from EDI, ethical, and sustainability perspectives (e.g. present a product related to the subject of a class; in addition to discussing the product’s engineering characteristics, extend the discussion to sustainability and diverse stakeholders perspective – who are the end users, what is the affordability, where does the raw material comes from, how could it be recycled etc.)

2. Applying and analysing:

Seek out case studies which can expose the students to a range of EDI issues and contexts, e.g.:

a. Examples of “sustainable” engineering solutions aimed toward “wealthy” users but not available or suitable for the “poor”. Question if EDI was considered in stakeholder groups (who are the target end users, what are their specific needs, are the solutions applicable and affordable for diverse socioeconomic groups (e.g. high-tech expensive sophisticated medical devices, luxury cars).

b. Examples of product design suffering from discriminatory unconscious bias (e.g. medical devices unsuitable for women (Phillips SP, 2022); “affordable housing projects” being unaffordable for the local community, etc.).

c. Positive examples of sustainable engineering solutions with strong EDI perspectives taken that are also financially viable (e.g. sustainable water and sanitation projects, seaweed farming for food security and climate change mitigation (Sultana F, 2023), sustainable gem production (Center for Responsible Business (CRB), 2023) etc.)

3. Implementing, evaluating, and creating:

a. Use existing scenario-based modules to focus on finding solutions for the sustainability problems that will improve socioeconomic equality, access to water, improvement of healthcare, and reduction of poverty. This will guide students to implement sustainability principles in engineering while addressing social issues and inequalities.

b. In project-based modules, ask students to link their work with a specific UNSDG and evidence an approach to EDI issues.

4. Provide visibility of additional opportunities:

Extracurricular activities (maker spaces, EWB UK’s Engineering for People Design Challenge, partnership with local communities, etc.) can represent an additional mechanism to bolster the link between sustainable engineering practice and EDI issues. Some of these initiatives can even be implemented within modules via topics, projects, and case studies.

A systematic strategic approach will ensure that students gain experience in considering the views of all stakeholders, and not only economic and technical drivers (Faludi, et al., 2023). They need to take account of local know-how and community engagement since not all solutions will work in all circumstances (Montt-Blanchard, Najmi, & Spinillo, 2023). Engineering decisions need to be made bearing in mind the ethical, cultural, and political questions of concern in the local setting. Professional engineers need to develop a global mindset, taking into account diverse perspectives and experiences which will increase their potential to come up with creative, effective, and responsible solutions for these global challenges. (Jordan & Agi, 2021).

Leading by example:

It is of paramount importance that students experience that the HE institution itself embraces an inclusive and sustainable mindset. This should be within the institutional strategy and policies, everyday operations and within the classroom. Providing an experiential learning environment with an inclusive and sustainable mindset can have a paramount impact on the student experience and attitudes developed (Royal Academy of Engineering, 2018).

Conclusion:

Engineering education must prepare future professionals for responsible and ethical actions and solutions. Only the meaningful participation of all members of a global society will bring us to a fully sustainable future. Thus, the role of engineering educators is to embed an EDI perspective alongside sustainability in the attitudes of future professionals.

Who is this article for? This article should be read by educators at all levels in higher education who are seeking an overall perspective on using PBL for integrating sustainability in engineering education. Engaging with this topic will also help to prepare students with the soft skill sets that employers are looking for.

Premise:

Engineering graduates are increasingly required to implement sustainability-focussed initiatives within industry, alongside enhanced expectations from professional bodies and the UK specification (UK-SPEC) for engineers (Engineering Council, 2024). However, a recent study of UK Higher Education institutions highlighted that only a handful have implemented Education for Sustainable Development (ESD) into their curricula in a systemic manner (Fiselier et al., 2018), which suggests many engineering institutions still need support in this area. This article aims to explain opportunities and challenges for integrating ESD into engineering programmes via project-based learning.

1. An overview of problem-based learning as a tool for teaching sustainability within engineering:

To develop sustainability-literate graduates, the Higher Education Academy (AdvanceHE) and the UK Quality Assurance Agency for Higher Education (QAA) emphasise that students need to:

understand what the concept of environmental stewardship means for their discipline and their professional and personal lives;
think about issues of social justice, ethics, and wellbeing, and how these relate to ecological and economic factors; and
develop a future-facing outlook by learning to think about the consequences of actions, and how systems and societies can be adapted to ensure sustainable futures (QAA & HEA, 2014).

Problem-Based Learning (PBL) provides a suitable teaching method for addressing these educational objectives. It is an influential approach in engineering education that emphasises real-world problem-solving and student-centred investigation. PBL deeply engages engineering students, prompting them to develop higher-level thinking skills while they personally confront and navigate economic, social, and environmental issues. This method fosters holistic systems thinking, interdisciplinary insights, ethical considerations, and an emphasis on the long-term viability of technical solutions (Cavadas and Linhares, 2023), while also inspiring and motivating learners (Loyens, 2015).

While PBL can be delivered through theoretical case study examples, the term is used interchangeably with Project-Based Learning within engineering education. Both problem-based learning and project-based learning share characteristics such as collaboration and group work, the integration of knowledge and practice, and foregrounding problem analysis as the basis of the learning process (De Graaff and Kolmos, 2003). One of the main differences is where the parameters lie: with problem-based learning the parameters are defined at the beginning and students are able to find a range of solutions; with project-based learning the parameters lie at the end and students are expected to reach a specific end solution (Savery, 2006). There is also a difference in the role of the tutor and the information they provide: in problem-based learning the tutor facilitates but gives little information, while in project-based learning they are both a facilitator and a source of knowledge (Savery, 2006). Project based learning may be more accepted within engineering education since it is considered to more closely resemble the reality of the profession (Perrenet, Bouhuijs and Smits, 2000), hence Aalborg’s working definition of PBL as “Problem-Oriented, Project-Organized, Learning” (Dym et al., 2005).

PBL thus facilitates the creation of immersive student-centric environments where group projects enable collaborative learning (Kokotsaki, Menzies and Wiggins, 2016). As Lozano et al. (2017) highlight, the nature of PBL advances critical thinking and problem-solving in engineering contexts, enabling students to critically reflect on sustainability concepts and apply this understanding to real-world challenges. Importantly, it is paramount in engineering education to foster action-oriented competencies and incorporate social contextualisation aspects (Fogg-Rogers et al., 2022), such as ethical nuances, justice, and equality, ensuring a comprehensive grasp of an engineer’s role amidst evolving societal and environmental challenges (Wang et al., 2022).

2. Overcoming challenges within PBL:

While PBL presents an obvious approach for embedding sustainability, there are a series of challenges which engineering educators need to overcome to facilitate transformational learning. This section presents some of the most common challenges encountered, along with pedagogic solutions.

Lack of apparent topic relevance
Sustainability topics can sometimes be treated as isolated topics, rather than an integrated aspect of an engineering problem. A perception of sustainability in engineering is that it is not implicit in design, manufacture, and operation; rather it is often perceived as an ‘add-on’ to technical skill development. This applies to both students and teachers: both require support to understand the relevance and complexities of sustainability. When academics delivering sustainability materials may struggle to relate the topic to their own engineering disciplines, students may fail to see how they can impact change. Students must work on real-world projects where they can make a difference locally or globally, and they are more inclined towards sustainability topics that are relevant to their subject discipline with subject experts.

Dealing with an overwhelming amount of information
Students can be overwhelmed by the large amounts of multidisciplinary information that needs to be processed when tackling real-world problems. This can also be a challenge for academics delivering teaching, especially if the topic is not related to their speciality. Additional support (and training), along with allocation of teaching workload, are needed to successfully integrate sustainability contexts for both staff and students.

Group work challenges
PBL is best conducted by mixing individual study and group work. However, groups can fail if group creation, monitoring, supporting, and assessing processes are inconsistent, or not understood by academic tutors or students. Tutors need to act as group facilitators to ensure successful collaborative learning.

Issues with continual engagement
PBL often requires active engagement of students over an extended period (several weeks or months). This can be a challenge, as over time, students’ focus and priorities can change. We suggest that whole programmes need to be designed around PBL components, so that other modules and disciplines provide the scaffolding and knowledge development to the relevant PBL topics.

Delivering PBL online

PBL is best delivered using experiential hands-on learning. For example, at UWE Bristol, this is provided through civic engagement with real-world industry problems and service learning through engagement with industry, schools, and community groups (Fogg-Rogers et al., 2017). This experiential learning was exceptionally challenging to deliver online during the COVID-19 pandemic, and programmes would need to be re-designed for online learning.

3. Recommendations for successful implementation of PBL:

Sustainability topics need to be embedded within engineering education so that each discipline-specific engineering problem is explored within PBL from a technical, economic, ethical, and sustainability perspective. Drawing from UWE Bristol’s journey of ESD implementation using PBL, key recommendations are outlined below.

Managing academic workload
In the initial phases of ESD integration at UWE Bristol, a small number of committed academics contributed a lot of time, effort, and dedication to push through and enable ESD acceptance from staff and students. Programme-wide implementation of ESD required wider support at the institutional level, alongside additional support for module leaders and tutors, so they felt capable of delivering ESD with a realistic workload.

Structured delivery of ESD
Structuring delivery over time and throughout different modules enables students to work through large amounts of information. Providing summative feedback/assessments during key phases of the PBL exercise can also help students stay on track and manage their workload. At UWE Bristol, group presentations with pass/fail grading are introduced mid-project, so students can present information gathered about the context, before beginning problem-solving.

Managing group work challenges
PBL is best conducted by mixing individual study and group work. Ensuring assessment briefs have implicit sustainability requirements is vital to embedding ESD concepts, so that students can see the need for engagement. This is further enhanced by stating the relevance to workplace contexts and UK-SPEC requirements. Tutors need to facilitate group dynamics and engagement, along with providing support structures for students who, for whatever reason, are unable to engage with group work.

Creating an enabling environment for ESD integration
The integration of sustainable development throughout the curricula at UWE Bristol has been supported at the institutional level, and this has been critical for the wide scale rollout. An institution-wide Knowledge Exchange for Sustainability Education (KESE) network was created to support staff by providing a platform for knowledge sharing. Within the department, Staff Away days were used to run sustainability workshops to discuss ESD and topics of interest to students. An initial mapping exercise was conducted to highlight where sustainability was already taught within the curriculum and to identify the discipline relevant contexts (Lamere et al., 2022). Further training and industrially relevant contexts were provided to convince some staff that sustainability needed to be included in the curriculum, along with evidence that it was already of great relevance in the wider engineering workplace. This led to the development of an integrated framework of key learning requirements which embedded professional attributes and knowledge of the UK-SPEC.

Student motivation and continual engagement

For sustainability education to be effective, the content coverage should be aligned, or better still, integrated, with the topics that form part of students’ disciplinary studies. To maintain continual engagement during the PBL delivery and beyond, clear linkages need to be provided between learning and future career-related practice-based sustainability activities. Partnerships have been developed with regional stakeholders and industry, to provide more context for real-world problems and to enable local service learning and community action (Fogg-Rogers, Fowles-Sweet, 2018). Industry speakers have also been invited to contribute to lectures, touching on a wide range of sustainability and ethical issues. ESD teaching is also firmly linked to the individual’s own professional development, using the UK-SPEC competency requirements, and linked to end-point assessments. This allows students to see the potential impact on their own professionalism and career development.

These recommendations can enable engineering educators to integrate sustainability topics within the curriculum using PBL to enhance student learning and engagement.
