Learning and teaching notes:
This guide, currently under review by the Engineering Council, maps the Engineering for One Planet (EOP) Framework to AHEP4. The EOP Framework is a practical tool for curricular supplementation and modification, comprising 93 sustainability focused learning outcomes in 9 topic areas.
The Lemelson Foundation, VentureWell, and Alula Consulting stewarded the co-development of the EOP Framework with hundreds of individuals mostly situated in the United States. Now, in collaboration with the EPC and Engineers Without Borders UK, the EOP Framework’s student learning outcomes have been mapped to AHEP4 at the Chartered Engineer (CEng) level to ensure that UK educators can more easily align these outcomes and corresponding resources with learning activities, coursework, and assessments within their modules.

Educational level: Beginner.
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.
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’.
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)
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.
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).
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.
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) 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.
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.
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.
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.
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:
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:
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.

Educational aim: The objective of this activity is to provide students with an understanding of the complexity of technology development and different considerations that need to be made by stakeholders in the design and implementation of a technology. The activity is set up as a role-play where students are assigned different roles as members of an expert panel providing feedback on the use of E-Scooters on a college campus.
Educational level: Beginner.
Learning and teaching notes:
Learners have the opportunity to:
Consider sustainability issues related to the design and use of devices and technology.
Discuss concerns related to safety and accessibility, that can be overlooked or not attended to when technology is developed under time pressure and when developers lack resources – human and material.
Practice a variety of communication modes.
Engage in research and reflection.
Teachers have the opportunity to:
Highlight issues revealing the intricate links between digital technology and the environment.
Demonstrate the value of perspective-taking and stakeholder engagement in technology development.
Reveal the ethical and accessibility aspects of technology development.
Informally evaluate critical thinking and communication skills.
Supporting resources:
Several different ethical frameworks, codes, or guidelines can be provided to students to prepare for the discussion or to reflect upon during their discussion depending on the students’ disciplinary composition. Here are a few examples:
One of the goals of this exercise is to motivate students to undertake their own research on the topic to prepare for the activity. But it is important to provide them with preliminary material to start their own research. Here are a few useful resources for this case:

Students assigned to the role of Eva Walker serve as the moderator and lead the conversation based on the script below.
The script provided below is there to guide the discussion, but you should leave room for the conversation to flow naturally and allow everyone to contribute.
One way to ensure students are prepared for the discussion is to assign a few questions from the script as a pre-discussion assignment (short answers). Similarly, to ensure students reflect on the discussion, they can be assigned the last question from the script as a post-discussion exercise. They can also be asked specifically about frameworks and concepts related to sustainability.
Role-play scenario narrative and description of roles:
Eva Walker recently started reporting about on-campus traffic issues for the student newspaper. She would have preferred to do more human-interest stories, but as a new member of the staff who had just moved from intern to full-time, she was happy to get whatever opportunity she could. Eva was studying both journalism and creative writing, and this was her dream on-campus job. She also realised that, even though many stories at first didn’t appear to her as though she would be interested in them, as she dug deeper she eventually found an angle with which she could strongly relate.
One weekday morning, Eva was working on yet another story on parking woes when Amina Ali, one of the editorial staff members, texted her to say that there had been an accident on campus; she just passed it at the intersection of the library and the recreation building, and it might be worth covering. Eva was at the library, and within no time, reached the spot of the accident.
When Eva arrived, a police vehicle, an ambulance, and a fire engine were all present at the scene, and near the accident site, an e-scooter lay smashed into a tree. It looked like the rider was sitting in the ambulance and was being treated by the medical staff. A little further away, Eva noticed the police speaking to a young woman in a wheelchair. Although Eva’s first instinct was to try to talk to the police or the medical staff to ascertain what had happened, she realised this probably wasn’t the best moment and she would have to wait until later for the official version of the event.
She looked around and saw a group of four students leaning against a wall with drinks in their hands. A couple of them were vaping. Eva thought that they looked like they had been here for a while, and she walked over to ask them what had happened. From the account they gave her, it appeared as if the e-scooter rider was coming around the bend at some speed, saw the woman in the wheelchair a little too late to ride past her, and, to avoid hitting her, leapt off his e-scooter and let the vehicle hit the tree. Things happened very quickly and no one was exactly sure about the sequence of events, but this was the rough story she got.
Later, she called the police department on campus and was able to speak with one of the officers to get an official account. The story was very similar to what she already knew. She did find out that nobody was seriously hurt and that the only injuries were to the e-scooter rider and were taken care of at the scene by the medical staff. When she asked about who was to blame or if any legal action was expected, she was told that there were no laws around the use of helmets or speeding for e-scooters yet and that she should reach out later for more information. Eva wrote up what she had so far, sent it over to the editorial staff, and considered her work done.
But as she was walking back to her halls of residence that evening, her attention was drawn to the large number of e-scooters parked near the library. As she crossed the central campus, she noticed even more e-scooters lying about the intersections, and there was a litter of them around the residence hall. She wondered why she hadn’t noticed them before. Her attention was drawn today, she thought, because of the accident and also because she saw a good Samaritan remove an e-scooter from the sidewalk, as it was blocking the path of one of the self-driving food delivery robots. It’s a sign, Eva thought, this is what she needs to look for more in her next article, the use of e-scooters on campus.
Eva recognised that, to write a balanced and informative article, as she had been taught to do, she would have to look at many different aspects of the use of e-scooters as well as look broadly at mobility on campus and the use of battery powered vehicles. She had also recently seen e-bikes on campus and, in addition to the food delivery robots, service robots in one of the buildings that she assumed was either delivering paperwork or mail. The accident had also made her realise that, when it came to mobility, accessibility was something that never crossed her mind but that she now understood was an important consideration. She hoped to learn more about it as her research progressed.
As background research for the article, Eva started reading up on articles and studies published about e-scooters, e-bikes, and urban mobility and came across a range of concerns that had been raised beyond accessibility. First, there were reports that e-scooters are not as environmentally friendly as many service providers had made them out to be. This is related to the production of the battery as well as the short lifespan of the vehicles, and as of yet, there has been no procedure implemented to reuse them(Pyzyk, 2019). Second, there were reports of littering, where e-scooters are often left on sidewalks and other places where they restrict movement of other vehicles, pedestrians, and in particular, those in wheelchairs (Iannelli, 2021). Finally, it was also clear from the reports that accidents and injuries have increased due to e-scooters, especially since many riders do not wear safety gear and are often careless, even inebriated, as there were little to no regulations (2021). When she approached her editor with an outline for an article, she was advised to do some more reporting by talking with people who could shed more light on the issue.
After some research, Eva shortlisted the following experts across fields related to e-scooters for an interview, and once she spoke with them, she realised that it would help her if she could get them to have a dialogue and respond to some of the questions that were raised by other experts. Therefore, she decided to conduct a focus group with them so that she achieved her goal of a balanced article and did not misrepresent any expert’s point of view.
Experts/roles for discussion:
1. Bryan Avery is co-founder and chief technology officer (CTO) of RideBy, an e-scooter company. RideBy is one of the options available on campus. Born in a small town, Bryan used to ride his bicycle everywhere while growing up, and for him, founding and leading an e-scooter company provided a chance to merge his interests in personal transportation and new forms of energy. He was a chemical engineer by training, and at a time when most of his friends ended up working for big oil companies, Bryan decided to work on alternative fuels and found himself developing expertise and experience with batteries. For most of the software- and mobile device-related development, RideBy outsourced the work and utilised ready-to-configure systems that were available. By only keeping the core device and battery functionality in-house, they could focus on delivering a much stronger product. Overall, he is quite happy with the success of RideBy so far and can’t help but extol the difference it can make for the environment.
2. Abiola Abrams is a professor of transportation engineering and an expert on mobility systems. Her work combines systems engineering, computer science, and data analytics. Her recent research is on urban mobility and micro-mobility services, particularly e-bikes. In her research, Dr. Abrams has looked at a host of topics related to e-bikes, many of which are also applicable to e-scooters, including the optimisation of hubs for availability, common path patterns of users, subscription use models, and the e-waste and end of lifecycle for these vehicles. Increasingly, she has become concerned about the abuse of some of these services, especially in cities that attract a lot of tourists, and about the rough use of the vehicles, so much so that many do not even last for a month. In a new project, she is investigating the effect of e-vehicles on the environment and has found that there is mixed evidence for how much difference battery-operated vehicles will actually make for climate change compared to vehicles that use fossil fuels.
3. Marco Rodrigues works as transportation director for the local county government where the university is based. As part of a recent bilateral international exchange, he got the opportunity to spend time in different cities in Germany to learn about local transportation. He realised very quickly that local transportation was very different in Germany; residents had a range of public, shared options that were missing in the United States. However, he also realised that e-mobility services were being considered across both countries. He investigated this further and found that Germany waited until it could pass some regulations before allowing e-mobility operators to offer services; helmets were mandatory on e-scooters and e-bikes, and riders had to purchase a nominal insurance policy. He also learned that there were strict rules around the sharing of data generated by the vehicles as well as the apps used by riders.
4. Judy Whitehouse is director of infrastructure and sustainability on campus and responsible for planning the long-term development of the campus from a space perspective, but also increasingly from a sustainability dimension. As the number of students has increased, so has the need for more infrastructure, including classrooms and halls of residence. This has also resulted in greater distances to be traveled on campus. Judy regards e-mobility options as a necessary component of campus life and has been a strong supporter for them. Lately, she has been called into meetings with safety and emergency management people discussing the issue of increased accidents on campus and the littering of e-vehicles across the campus. Not only is it bad for living on campus, but it is also bad for optics. A recent photo featured in the campus newspaper was a stark reminder of just how bad it can look. She is further divided on the use of e-scooters due to misgivings about the sustainability of battery use, as new research suggests that manufacturing batteries and disposing them are extremely harmful for the environment.
5. Aaron Schneider heads Campus Mobility, a student interest group focused on autonomous vehicles development and use. The group members come from different degree programmes and are interested in both the technical dimensions of mobile solutions and the policy issues surrounding their implementation. Aaron himself is a computer science student with interests in data science, and with some of his fellow members from the policy school, he has been analysing a range of mobility-related datasets that are publicly available online. Of these, the data on accidents is quite glaring, as the number of accidents in which e-scooters are involved has gone up significantly. Aaron and his friends were intrigued by their findings and approached some of the companies to see if they would share data, but they were disappointed when they could not get access. Although the companies said it was due to privacy reasons, Aaron was not too convinced by that argument. He was also denied access to any internal reports about usage patterns of accidents. Ideally, he would have liked to know what algorithms were used for optimising delivery and access, but he knew he was not going to get that information.
6. Sarah Johnson is the head of accessibility services on campus and is responsible for both technology- and infrastructure-related support for students, faculty, and staff. The growth of the physical campus and the range of technological offerings has significantly increased the workload for her office, and they are really strained in terms of people and expertise. The emphasis from the university leadership is largely on web and IT accessibility, as teaching and other services are shifting quickly online, but Sarah realises that there is still an acute need to provide physical and mobility support to many members of the community. Although all the new buildings are up to code in terms of accessibility, there is still work to be done both for the older buildings and especially for mobility. Campus beautification does not always go along with access. She is also worried about access to devices, as taking part in any campus activity requires not just a computer, but also access to mobile devices that are out of reach economically for many and not easy to use.
Role-play script:
To help get the dialogues started and based on her prior conversation with the group, Eva has prepared some initial questions:
What role are you playing and, from your perspective, what do you see as the biggest pros of using e-vehicles, especially e-scooters on campus?
From your perspective, what do you see as the biggest downside of using e-vehicles, especially e-scooters on campus?
Can you confidently say that e-scooters are an environmentally friendly option?
What current accessibility accommodations would be impacted by the use of e-vehicles, and what new, potential accessibility accommodations might arise from increased use of e-vehicles?
Would we be better off waiting for more regulations to come before deploying these vehicles on campus and, if so, what should those regulations look like?
Should we use automatic regulation of speed on the vehicle based on where it is and/or inform authorities if it is violated?
Can we control where it can go or penalise if not put back?
What guidelines do you recommend for e-scooter usage on campus?

Learning and teaching notes:
This learning activity is designed to build students’ awareness of different dimensions of sustainability through reflection on their everyday activities.This activity is presented in two parts. If desired, a teacher can use Part one in isolation, but Part two develops and complicates the concepts presented in Part one to provide for additional learning. Educators could incorporate shorter or longer versions of the activity as fits their needs and contexts. This activity could be presented without a focus on a specific area of engineering, or, students could be asked to do this around a particular discipline. Another powerful option would be to do the activity once at the beginning of term and then again at the end of term, asking students to reflect on how their perceptions have changed after learning more about sustainability.
This activity could be delivered as an in-class small group discussion, as an individual writing assignment, or a combination of both. Students could even make a short video or poster that captures their insights.
Learners have the opportunity to:
Develop awareness around personal connections to sustainability issues;
Engage in reflection;
Undertake informal research;
Practice communication in multiple modes.
Teachers have the opportunity to:
Introduce topics of sustainable development the UNSDGs, and dimensions of sustainability;
Evaluate critical thinking and/or written and/or verbal communication skills;
Introduce or contextualise issues around materials, manufacturing, supply chain, energy/water consumption, and end-of-life.
Choose 3 activities that you do every day. These could be things like: brushing your teeth, commuting, cooking a meal, messaging your friends and family, etc. For each activity, consider the following as they connect to this activity:
Materials and energy required to do the activity;
Manufacturing and transportation required to enable you to do it;
Water consumed and waste generated for all of the above.
To help you consider these elements, list the “stuff” that is involved in doing each activity—for example, in the case of brushing your teeth, this would include the toothbrush, the toothpaste, the container(s) the toothpaste comes in, the sink, the tap, and the water.
What are the “ingredients” or materials that make up this stuff?
Where is this stuff made? If you don’t know, can you find out? If you can’t find out, why?
How did this stuff get to you? Can you uncover the “chain of custody” from where it was made to how it arrived in your possession? If not, what links in the chain are missing and what might that mean?
Where does it go when you are done with it, and whose responsibility is it? How circular is the waste disposal system related to this stuff?
Who besides you is involved in this process of supply, use, and disposal? This could include companies, government entities, and/or community and financial organisations.
Which engineering disciplines inform the creation, distribution, use, and disposal of this stuff?
Part two:
Teachers may want to preface this part of the activity through an introduction to the SDGs, or, they may want to allow students to investigate the SDGs as they are related to these everyday activities. Students could engage in the following:
Research and report on which SDG(s) are connected to this daily activity.
Compare and contrast how this daily activity is conducted in different countries—how do differences in policies and infrastructure affect how it is done, and how sustainable it is?
Suggest improvements to systems that would enable a more sustainable approach to this activity, from the perspective of design, manufacture, use, and disposal.
Debate the challenges, risks, and benefits to enacting these improvements.
Create a solution to an aspect of the activity that is not as sustainable as it could be.
Develop a campaign to influence a stakeholder to change a process in such a way that would make the activity more sustainable.

Learning and teaching notes:
The following are a set of use cases for a maturity model designed to improve energy and resource efficiency in manufacturing facilities. This guide can help engineering educators integrate some of the main concepts behind this model (efficient use of energy and resources in factories in the context of continuous improvement and sustainability) into student learning by showcasing case study examples.
Teachers could use one or all of the following use cases to put students in the shoes of a practicing engineer whose responsibility is to evaluate and improve factory fitness from a sustainability perspective.
Factory assessment in multiple assembly facilities for an aircraft manufacturer:
The assessment is part of the following use case on this industrial energy efficiency network (IEEN):
The company operates in the aerospace sector and runs 11 manufacturing sites that employ approximately 50000 people across 4 European countries. Most of the sites are responsible for specific parts of the aircraft i.e. fuselage, wings. These parts once manufactured are sent to two final assembly sites. Addressing energy efficiency in manufacturing has been a major concern for the company for several years.
It was not until 2006 that a corporate policy was developed that would formalize efforts towards energy efficiency and set a 20% reduction in energy by the year 2020 across all manufacturing sites. An environmental steering committee at board level was set up which also oversaw waste reduction and resource efficiency. The year 2006 became the baseline year for energy savings and performance measures. Energy saving projects were initiated then, across multiple manufacturing sites. These were carried out as project-based activities, locally guided by the heads of each division and function per site.
A corporate protocol for developing the business case for each project is an initial part of the process. It is designed to assign particular resources and accountabilities to the people in charge of the improvements. Up to 2012, improvement initiatives had a local focus per site and an awareness-raising character. It was agreed that in order to replicate local improvements across the plants a process of cross-plant coordination was necessary. A study on the barriers to energy efficiency in this company revealed three important barriers which needed to be addressed:
Lack of accountability: The site energy manager is responsible for reducing the site’s energy consumption but only has authority to act within a facility’s domain–that is, by improving facilities and services, such as buildings and switchgear. They are not empowered to act within a manufacturing operations parameter. Therefore, no one is responsible for reducing energy demand.
No clear ownership: Many improvements are identified but then delayed due to a lack of funding to carry out the works. This is because neither facilities nor manufacturing operations agree whether the improvement is inside their parameter: typically, facilities claim that it is a manufacturing process improvement, and operations claim that any benefit would be realized by facilities. Both are correct, hence neither will commit resources to achieve the improvement and own the improvement.
No sense of urgency: A corporate target exists for energy reduction–but the planned date for achieving this is 2020.
The solution that the environmental steering committee decided to support, was the creation of an industrial energy efficiency network (IEEN). The company had previously done something similar when seeking to harmonize its manufacturing processes through process technology groups (Lunt et al., 2015). This approach consists of each plant nominating a representative who is taking the lead and coordinating activities. It is expected that the industrial network would contribute to a significant 7% share out of the 20% energy reduction target for the year 2020 since its establishment as an operation in 2012.
The network’s operations are further facilitated with corporate resources such as online tools that help practitioners report and track the progress of current projects, review past ones, and learn about best-available techniques. This practice evolved into an intranet website that is further available to the wider community of practitioners and aims to generate further interest and enhance the flow of information back to the network. Additionally, a handbook to guide new and existing members in engaging effectively with the network and its objective has been developed for wider distribution. These tools are supported by training campaigns across the sites.
Most of the network members also act as boundary spanners (Gittell and Weiss, 2004) in the sense that they have established connections to process technology groups or they are members of these groups as well. This helps the network establish strong links with other informal groups within the organization and act as conductor for a better flow of ideas between these groups and the network. Potentially, network members have a chance to influence core technology groups towards energy efficiency at product level.
On average, a 5-10% work-time allocation is approved for all network members to engage with the network functions. In case a member is not coping in terms of time management there is the option of sub-contracting the improvement project to an external subcontractor who is hired for that particular purpose and the subcontractor’s time allocation to the project can be up to 100%.
“….by having the network we meet and we select together a list of projects that we want to put forward to access that central pot of money. So we know roughly how much will be allocated to industrial energy efficiency and so we select projects across all of the sites that we think will get funded and we put them all together as a group…so rather than having lots of individual sites making individual requests for funding and being rejected, by going together as a group and having some kind of strategy as well…”
Each dot on each of the model rows represents the relative efficiencies that a factory achieves in saving energy and resources through best practice (5 of 11 factories represented here, each delivering an aircraft part towards final assembly). The assessment allowed this network of energy efficiency engineers and managers to better understand the strengths and weaknesses in different factories and where the learning opportunities exist (and against which dimension of the model).
2. The perception problem in manufacturing processes and management practice:
The following assessment is performed in a leading aerospace company where two senior engineering managers (green and orange lines) find it difficult to agree on the maturity of different practices currently used at the factory level as part of their environmental sustainability strategy.
This assessment was part of the following use case:
The self-assessment was completed by the head of environment and one of his associates in the same function. These two practitioners work closely together and are based in the UK headquarters. Even though the maturity profiles do not vary significantly (1 level plus or minus) it is clear that there is very little overall agreement on the maturity levels in each dimension.
3. Using the maturity model as a consensus building tool in a factory:
Seven practitioners from different parts of the business (engineering, operations, marketing, health and safety etc.) were brought together to understand how they think the factory performs. The convergence between perceptions was very small and this would indicate high levels of resistance to change and continuous improvement. For example, if senior managers think they are doing really well, they will not invest time and effort in better practices and technologies.
A timeline (today +5years) was used to understand where they think they are today and where they want to be tomorrow.
This can be one of the ways of thinking about improvements that need to occur, starting with areas of interest that are underperforming and developing the right projects to address the gaps.

Educational level: Intermediate.
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.
Explore the ethical dimensions of engineering decisions, particularly concerning sustainability and resource management.
Examine the influence of policy and stakeholder perspectives on the adoption of green hydrogen within the aviation industry.

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

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.

Learning and teaching notes:
Before engaging with the case study, learners should be familiar with the process of calculating embodied carbon and conducting a cost-benefit analysis. The case study is presented in three parts. In Part one, an ambitious urban revitalisation project is under development, and a project manager needs to find a balance between financial considerations and the urgent need for sustainable, low-embodied carbon construction. In Part two, the project being developed is located in a coastal area prone to climate change-related disasters. The team needs to ensure that the project is durable in the face of disasters and, at the same time, upholds sustainability principles. Lastly, in Part three, stakeholders involved in the two previous projects come together to identify potential synergies.
Learners have the opportunity to:
Assess the ethical dimensions of construction scenarios, particularly the trade-offs between socio-economic constraints and environmentally-friendly practices.
Identify potential conflicts between environmental advocacy and financial considerations, fostering critical thinking in real-world construction project dilemmas.

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.

Who is this article for: This article should be read by educators at all levels in Higher Education who wish to understand how engineering practice can promote sustainable and ethical outcomes in equality, diversity, and inclusion.

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.
