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.

Learning and teaching notes:
This is an example project that could be adapted for use in a variety of contexts. It asks students to devise a “sustainability dashboard” that can not only track indicators of river system sustainability through technical means, but also communicate the resulting data to the public for the purpose of policy decisions. Teachers should ideally select a local river system to focus on for this project, and assign background reading accordingly.
Learners have the opportunity to:
Investigate the links between history, politics, and engineered systems;
Research existing data sources;
Devise a technical solution for community impact.
Teachers have the opportunity to:
Showcase real-world implications of the SDGs;
Integrate technical learning with sustainability issues;
Emphasise the importance of the engineer’s role in public life.
Two vital and unique resources for the planet are water and air. Any alterations in their composition can have detrimental effects on humans and living organisms. Water uses across New Mexico are unsustainable. Reduced precipitation and streamflows cause increased groundwater use and recharge. Serious omissions in state water policy provide no protection against complete depletion of groundwater reserves.
The water governance status quo in New Mexico will result in many areas of New Mexico running out of water, some sooner, some later, and some already have. Because Water is Life, water insecurity will cause economic insecurity and eventual collapse.
Water resources, both surface and groundwater, and total water use, determine the amount of water use that can be sustained, and then reduce total water use if New Mexico is to have water security. The public must therefore recognise that action is required. Availability of compiled, accessible data will lead to and promote our critical need to work toward equitable adaptation and attain sustainable resiliency of the Middle Rio Grande’s common water supply and air quality.
A data dashboard is needed to provide on-line access to historical, modern, and current perspectives on water, air quality, health, and economic information. A dashboard is needed to help inform the public about why everyone and all concerned citizens, institutions and levels of government must do their part!
Project brief:
The Middle Rio Grande region of New Mexico has particular sustainability and resilience requirements and enforceable legal obligations (Rio Grande Compact) to reduce water depletions of the Rio Grande and tributary groundwater to sustainable levels. However, there is a lack of accessible depictions of the Middle Rio Grande’s water supply and demand mismatch. Nothing publicly accessible illustrates the surface water and groundwater resources, water uses, and current water depletions that cannot be sustained even if water supplies were not declining. Therefore, there is a corresponding lack of public visibility of New Mexico’s water crisis, both in the Middle Valley and across New Mexico. Local water institutions and governments are siloed and have self-serving missions and do not recognise the limits of the Middle Valley’s water resources.
A water data dashboard is needed to provide online open access to historical, modern, and current perspectives on water inflows, outflows, and the change in stored surface and groundwater. This dashboard should inform the public about why everyone and all water institutions and levels of government must do their part!
Given:
Data from numerous on-line and paper or spreadsheet data sources
Law of the Rio Grande
The 2004 water budget components and historical information.
Objectives:
Engage data providers to cooperatively secure access to the public data they collect and maintain.
Create one website Dashboard to present the relevant water data of the Middle Rio Grande.
Demonstrate the function and form of the Water Data Dashboard to illustrate the value of simplified presentation of aggregated data.
Illustrate the value of creating procedures for data aggregation and presentation in simplified, accessible formats so that the prototype dashboard is taken over by an institution with the resources to build and maintain an improved second-generation version.
Provide selected water data sets as set forth in 2019 Water Data Act standards and procedures to the NM Water Data Initiative.
Find a long-term home for the dashboard project with a government agency or Middle Rio Grande water institution.

Educational level: Beginner.
Learning and teaching notes:
The purpose of this exercise is to encourage students to think in a socio-technical perspective of delivering extreme low carbon housing (e.g. Passivhaus), in order to support the occupants in adapting to new technologies and low-carbon lifestyle, shifting the paradigm from building isolated energy efficient homes to forming low-carbon communities.
Learners have the opportunity to:
Practice stakeholder engagement;
Consider physiological and ecological effects of engineering design and technology;
Practice communication in multiple modes;
Teachers have the opportunity to:
Integrate technical learning on energy-efficient buildings such as emerging technologies and sustainability analysis;
Highlight the effects that engineering design and technology has on human behaviour;
Informally evaluate collaboration, critical thinking, and communication.
Before beginning the activity, teachers and learners will want to become familiar with the following concepts.
Performance gap:A performance gap is a disparity that is found between the energy use predicted and carbon emissions in the design stage of buildings and the energy use of those buildings in operation.
Rebound effect: The rebound effect deals with the fact that improvements in efficiency often lead to cost reductions that provide the possibility to buy more of the improved product or other products or services (Thiesen et al., 2008).
Adaptive comfort:The adaptive approach to thermal comfort recognises that people are not passive with regard to their thermal environment, but actively control it to secure comfort. Thermal comfort can thus be seen as a self-regulating system, incorporating not only the heat exchange between the person and the environment but also the physiological, behavioural and psychological responses of the person and the control opportunities afforded by the design and construction of the building (Humphreys & Nicol, 2018).
Energy behaviour: Energy behaviour denotes behaviour or behavioural patterns related to energy use. Research has stressed the important role occupants play in determining the energy use of buildings (Janda, 2011).
Usability and control: This presents how accessible and user-friendly the control systems are in a building. For instance, where the control panels are located, how easy it is to open a window, or to understand the control panel. (Stevenson et al., 2013).
Resident engagement plan:A resident engagement plan or strategy maps out a path to communicate and support residents for general or specific tasks. Examples can be found here (Home Upgrade Hub, 2022 p20 and p30; Social Housing Retrofit Accelerator, n.d.)
Activity overview:
Students will role-play the post occupancy stage of inhabiting a Passivhaus home by playing different characters with different priorities (and personalities). Students will need to learn what new technologies and features are included in Passivhaus and what difficulties/problems the residents might encounter, and at the same time familiarise themselves with contemporary research on energy behaviour, performance gap, rebound effect, as well as broader issues in decarbonisation transition such as social justice and low carbon community building. Through two community meetings, the community manager needs to resolve the residents’ issues, support the residents in learning and adapting their behaviours, and devising an engagement plan to allow the residents to form a self-governed low-carbon community.
Step one: Preparation prior to class:
Provide a list of reading materials on ‘performance gap’, ‘rebound effect’, ‘adaptive comfort’, energy behaviour, usability and control literature, as well as on Passivhaus and examples of low-carbon features and technologies involved to get a sense of what difficulties residents might encounter.
To prepare for the role-play activity, assign students in advance to take on different roles (randomly or purposefully), or let them self-assign based on their interests. They should try to get a sense of their character’s values, lifestyle, priorities, abilities. Where no information is available, students can imagine the experiences and perspectives of the residents. Students assigned to be community managers or building associations will prepare for the role-play by learning about the Passivhaus system and prepare ways to support occupants’ learning and behaviour adaptation. The goal is to come up with an engagement plan, facilitate the residents to form their own community knowledge base and peer support. (Considering 1. Who are you engaging (types of residents and their characteristics); 2. How are you engaging (level of engagement, types of communication; 3. When are you engaging (frequency of engagement)
Step two: In class, starting by giving prompts for discussions:
Below are several prompts for discussion questions and activities that can be used. Each prompt could take up as little or as much time as the educator wishes, depending on where they want the focus of the discussion to be.
Discuss what support the residents might need in post occupancy stage? Who should provide (/pay for) the support? For how long? Any examples or best practice that they might know? Does support needs to be tailored to specific groups of people? (see extra prompts at the end for potential difficulties)
Discuss what the risks are involved in residents not being sufficiently supported to adapt their behaviour when living in a low-carbon house or Passivhaus? (reflect on literature)
Discuss what are the barriers to domestic behaviour change? What are the barriers to support the residents in changing behaviour and to build low-carbon community?
Step three: Class 1 Role Play
Prior to the Role Play, consider the following prompts:
Consider the variety of residents and scenarios:
Their varying demographics, physical and mental abilities, lifestyle and priorities. The following characters are examples. Students can make up their own characters. Students can choose scenarios of
1) social housing or;
2) private owner-occupier
Social housing tenants will likely have a more stretched budget, higher unemployment rate and a bigger proportion of disabled or inactive population. They will have different priorities, knowledge and occupancy patterns than private owner-occupier, and will be further disadvantaged during decarbonisation transition (Zhao, 2023). They will need different strategies and motivations to be engaged. The characters of residents could be chosen from a variety of sources (e.g. RIBA Brief generator), or based on students’ own experiences. Each character needs to introduce themselves in a succinct manner.
Other stakeholders involved include:
Developer/ housing association/ council
Passivhaus designer/architect
Engineer
Community/property manager
They are role-specific characters that don’t necessarily need a backstory. They are there to listen, take notes, give advice and come up with an engagement plan.
Consider the post occupancy in different stages:
Prior to move-in
Move-in day
The initial month
Change of season
Quarterly energy audit meeting
Consider the difficulties the residents might encounter:
Where is the thermostat?
Where is the radiator?
How do I increase the temperature in the room?
It’s very stuffy and hot in the south-facing bedroom
What does the MVHR do?
Why is the MVHR so noisy?
Does PV panel supply electricity to my washing machine? When should I put my washing on?
Do I get paid from the electricity generated from the PV panel?
Why is my energy bill higher than expected?
Consider the different engagement levels of the residents:
20-60-20: 20% very engaged, 60% follows, 20% not engaged
How do you ensure the maximum level of satisfaction from all residents, including the ones not so engaged?
How to encourage the residents to take ownership and responsibility?
The role-play consists of two community meetings over two classes. The first meeting is held at two weeks after move-in date. The second meeting at 6 months of occupancy. The meeting should include a variety of residents on one side, and the ‘chair’ of the meeting on the other. (Consider the accessibility and inclusivity of the meetings as when and where those will be held). In the first meeting, residents will get to know each other, ask questions about house-related problems occurred in the first two weeks, voice concerns. Community managers/council members will chair the meeting, take notes and make plans for support. The teacher should act as a moderator to guide students through the session. First the teacher will briefly highlight the issue up for discussion, then pass it to the ‘chair’ of the meeting. The ‘chair’ of the meeting will open the meeting with the purpose of the meeting – to support the residents and facilitate a self-governed low carbon community. They then ask the residents to feedback on their experience and difficulties. At the end of the first meeting, the group of students will need to co-design an engagement plan, including setting agendas for the second meeting in a 6-month interval (but in reality will happen in the second class) and share the plan with the residents and the class. The teacher and class will comment on the plan. The group will revise the plan after class so it’s ready for the second meeting.
Step four: Homework tasks: Revising the plan
The students will use the time before the second class to revise the plan and prepare for challenges, problems occurred over the 6-months period.
Optional wild cards could be used as unpredictable events occur between the first and second meeting. Such events include:
Energy price dramatically increase (or decrease)
Heat wave
Heavy rain for three months (no solar gain)
Whole grid decarbonisation (might affect occupants with gas central heating)
Step five: Class 2 Role play
The second meeting in the second class will either be chaired by community managers/council members, or be chaired by a few residents, monitored by community managers/council members. The second meeting begins the same way. The students playing residents should research/imagine problems occurred during the 6 months period (refer to literature), and what elements of the engagement plan devised at the end of the first meeting worked and what hasn’t worked. The ‘chair’ of the meeting will take notes, ask questions or try to steer the conversations. At the end of the second meeting, the ‘chair’ of the meeting will reflect on the support and engagement plan, revise it and make a longer-term plan for the community to self-govern and grow. At the end of this class, the whole class could then engage in a discussion about the outcome of the meetings. Teachers could focus on an analysis of how the process went, a discussion about broader themes of social justice, community building, comfort, lifestyle and value system. Challenge students to consider their personal biases and position at the outset and reflect on those positions and biases at the end of the meeting.

Learning and teaching notes:
This case study is focused on the role of engineers to address the problem of plastic waste in the context of sustainable operations and circular business solutions. It involves a team of engineers developing a start-up aiming to tackle plastic waste by converting it into infrastructure components (such as plastic bricks). As plastic waste is a global problem, the case can be customised by instructors when specifying the region in which it is set. The case incorporates several components, including stakeholder mapping, empirical surveys, risk assessment and policy-making. This case study is particularly suitable for interdisciplinary teamwork, with students from different disciplines bringing their specialised knowledge.
The case study asks students to research the data on how much plastic is produced and policies for the disposal of plastic, identify the regions most affected by plastic waste, develop a business plan for a circular business focused on transforming plastic waste into bricks and understand the risks of plastic production and waste as well as the risks of a business working with plastic waste. In this process, students gain an awareness of the societal context of plastic waste and the varying risks that different demographic categories are exposed to, as well as the role of engineers in contributing to the development of technologies for circular businesses. Students also get to apply their disciplinary knowledge to propose technical solutions to the problem of plastic waste.
The case is presented in parts. Part one addresses the broader context of plastic waste and could be used in isolation, but parts two and three further develop and add complexity to the engineering-specific elements of the topic.
Learners have the opportunity to:
apply their ethical judgement to a case study focused on a circular technology;
understand the national and supranational policy context related to the production and disposal of plastic;
analyse engineering and societal risks related to the development of a novel technology;
develop a business model for a circular technology dealing with plastic waste;
identify the key stakeholder groups in the development of a circular business model;
reflect on how risks may differ for different demographic groups and identify the stakeholder groups most vulnerable to the negative effects of plastic waste;
develop an empirical survey to identify the risks that stakeholders affected by or working with plastic waste are exposed to;
develop a risk assessment to identify the risks involved in the manufacturing of plastic waste bricks;
provide recommendations for lowering the risks in the manufacturing of plastic bricks.
Teachers have the opportunity to include teaching content purporting to:
Physico-chemical properties of plastic waste;
Manufacturing processes of plastic products and plastic bricks;
Sustainable policies targeting plastic usage and reduction;
Climate justice;
Circular entrepreneurship;
Risk assessment tools such as HAZOP and their application in the chemical industry.
Plastic pollution is a major challenge. It is predicted that if current trends continue, by 2050 there will be 26 billion metric tons of plastic waste, and almost half of this is expected to be dumped in landfills and the environment (Guglielmi, 2017). As plastic waste grows at an increased speed, it kills millions of animals each year, contaminates fresh water sources and affects human health. Across the world, geographical regions are affected differently by plastic waste. In fact, developing countries are more affected by plastic waste than developed nations. Existing reports trace a link between poverty and plastic waste, making it a development problem. Africa, Asia and South America see immense quantities of plastic generated elsewhere being dumped on their territory. At the moment, there are several policies in place targeting the production and disposal of plastic. Several of the policies active in developed regions such as the EU do not allow the disposal of plastic waste inside their own territorial boundaries, but allow it on outside territories.
Optional STOP for activities and discussion
Conduct research to identify 5 national or international regulations or policies about the use and disposal of plastic.
Compare these policies by stating which is the issuing policy body, what is the aim and scope of the policy.
Reflect on the effectiveness of each policy and debate in class what are the most effective policies you identified.
Write a reflection piece based on a policy of your choice targeting the use or disposal of plastic. In this reflection, identify the benefits of the policy as well as potential limitations. You may consider how you would improve the policy.

Impressed by the magnitude of the problem of plastic waste faced today, together with a group of friends you met while studying engineering at the Technological University of the Future, you want to set up a green circular business. Circular business models aim to use and reuse materials for as long as possible, all while minimising waste. Your concern is to develop a sustainable technological solution to the problem of plastic waste. The vision for a circular economy for plastic rests on six key points (Ellen McArthur Foundation, n.d.):
Elimination of problematic or unnecessary plastic packaging through redesign, innovation, and new delivery models is a priority
Reuse models are applied where relevant, reducing the need for single-use packaging
All plastic packaging is 100% reusable, recyclable, or compostable
All plastic packaging is reused, recycled, or composted in practice
The use of plastic is fully decoupled from the consumption of finite resources
All plastic packaging is free of hazardous chemicals, and the health, safety, and rights of all people involved are respected

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.

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.

To encourage students to propose innovative and comprehensive solutions for sustainable urban development.
Educational level: Intermediate.
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.

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.

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.

Who is this article for? This article should be read by Chemical Engineering educators in higher education who are seeking to integrate sustainability in their project modules. Engaging with this topic will also help to prepare students with the soft skill sets that employers are looking for.
Premise:
The design project (DP) is considered to be the major focus of the CE curriculum, where students work in groups to design a complete chemical process – feeds, products process routes, energy requirements, financial aspects and emissions. It is considered challenging for various reasons including the following: the requirement to recall and combine knowledge covered previously in taught classes (some of which may have been forgotten), dealing with a huge corpus of data (unavailability, uncertainty, some being in conflict and some being superfluous) and all the design decisions that need to be made from many options. This is a major contrast with standard taught modules where all the data required is normally provided in advance. Just making decisions is not enough – they need to be timely and justified otherwise the project may be rushed and may not complete by the deadline. This is why the DP is valued by employers. Furthermore, if Education for Sustainable Development (ESD) is embedded in the design project, it is more likely that students will take forward sustainability into the workplace. Figure 1 illustrates Chemical processes and the design project.
1.Subject (CE) and DP pictorial representations:
Part (a) is a generic representation of a chemical process and shows the input-output nature of chemical processes. A chemical process takes a feed and converts it to useful products (the process shown has two equipment units and four streams). Part (b) is a representation of the design project, where the specification (or brief) is provided to groups at the start (DSpec) and the final submission (or solution) is the information in part (a). Part (c) shows that specifications can be product-based (the top two) or feed-based (the bottom two). The dashed lines indicate specifications where the flowrate and composition of the feed/product is subject to design choice – a typical factor that will extend the design procedure and require more decision-making.
2. Inclusion of sustainability in the project topic and communication with students:
This is fairly straightforward in CE design projects, because of the circular economy and the associated waste minimisation. So, from Figure 1, a feed-based (rather than product-based) specification can be employed. Topics that have been used at Strathclyde in recent years have been the utilisation of coffee grounds, food waste and (in 2024) green and garden waste. It is helpful that such topics can be linked to many of the UN SDGs. Furthermore, waste products are often complex with many components, and one of the characteristics of chemical engineering is the various separation techniques. These two factors should be communicated to students to improve engagement.
3. Inclusion of sustainability as an ESD activity to be carried out by groups:
One of the complicating factors about the UN SDGs is that there are so many, meaning that there is the possibility of a chemical process having both positive and negative impacts on different SDGs. This means that groups really need to consider all of the SDGs. This might be conveniently demonstrated as per Table 1. Certainly, it would be hoped that there are more ticks in column 2 than in column 3. Column 4 corresponds to minimal change, and column 5 where there is not enough information to determine any impact.
Table 1: Sustainability rating form for design project submissions
As an example, consider a design project which is based on better utilisation of green waste. Let us say that this results in less greenhouse gas emissions, as well as there being less need to plant and harvest plants. This will result in positive outcomes for SDG12 and SDG13. There are also positive effects because more land can be used for crops, and there will be higher plant coverage during the year. It could be argued then that there are minor positive effects om SDG2 and SDG3. The subsequent SDG profile in Table 1 shows two major impacts and two minor impacts – this might be typical for DPs.
4. Assessment of sustainability in the design project:
Table 2 shows the typical sections in a DP submission. For convenience these are shown as having equal 20-mark contributions. One way of determining marks is to divide these sections into a number of dimensions, for example: use of the literature, technical knowledge, creativity/innovation and style/layout. Sustainability could then be included as a fifth dimension. It is then a case of determining the sustainability dimension for each of the marking sections. It could be argued that sustainability is particularly important at the start of the project (when feeds and amounts are being decided) and at the end (when the final process is being assessed). This explains the larger weightings in Table 2. Coherence refers to how well the submission reads in terms of order and consistency and is thus independent of sustainability. The weightings are subject to debate, but they do at least give the potential for consistent (and traceable) grading between different assessors.
