Who is this article for?: This article should be read by educators at all levels of higher education looking to embed and integrate ESD into curriculum, module, and / or programme design.
This experiential activity aims to incorporate sustainability reflections into students’ group work. It uses a selection of materials with different properties to engage participants in building a wind turbine prototype based on a contextualised negotiation of multiple facets of sustainability.
Taking a disciplinary standpoint, participants first assume one of four engineering roles to identify specific sustainability priorities based on their role’s responsibilities and expertise. Next, they represent the perspective of their assigned role in an interdisciplinary group to optimise sustainability in the design of a wind turbine.
Throughout the activity, students are given targeted and short theoretical input on a selection of transversal skills that facilitate the integration of sustainability in group work: systems thinking, negotiation skills and perspective taking.
This activity guide provides the outline and material to assist the facilitator to prepare, and the slides and handouts for teaching the activity in approximately 75min. It can be facilitated with tangible objects (e.g. LEGO) as well as online. We invite you to adapt this activity to your context and tangibles availability.

Activity: Assessment. This example demonstrates how the questions provided in Assessing ethics: Rubric can be used to assess the competencies stipulated at each level.
Authors: Dr. Natalie Wint (UCL); Dr. William Bennett (Swansea University).
This example demonstrates how the questions provided in the accompanying rubric can be used to assess the competencies stipulated at each level. Although we have focused on ‘Water Wars’ here, the suggested assessment questions have been designed in such a way that they can be used in conjunction with the case studies available within the toolkit, or with another case study that has been created (by yourself or elsewhere) to outline an ethical dilemma.
Year 1
Personal values: What is your initial position on the issue? Do you see anything wrong with how DSS are using water? Why, or why not?
Students should provide a stance, but more importantly their stance should be justified. In this instance this may involve reference to common moral values such as environmental sustainability, risk associated with power issues and questions of ownership.
Professional responsibilities: What ethical principles and codes of conduct are relevant to this situation?
Students should refer to relevant principles (e.g. from the Joint Statement of Ethical Principles). For example, in this case some of the relevant principles may include (but not be limited to) “protect, and where possible improve, the quality of built and natural environment”, “maximise the public good and minimise both actual and potential adverse effects for their own and succeeding generations” and “take due account of the limited availability of natural resources”.
Ethical principles and codes of conduct can be used to guide our actions during an ethical dilemma. How does the guidance provided in this case align/differ with your personal views? (This is a question we had created in addition to those provided within the case study to meet the requirements stipulated in the accompanying rubric.)
Students’ answers will depend upon those given to the previous questions but should include some discussion of similarities and differences between their own initial thoughts and principles/codes of conducts, and allude to the tensions involved in ethical dilemmas and the impact on decision making.
What are the moral values involved in this case and why does it constitute an ethical dilemma? (This is a question we had created in addition to those provided within the case study to meet the requirements stipulated in the accompanying rubric.)
Students should be able to identify relevant moral values and explain that an ethical dilemma constitutes a problem in which two or more moral values or norms cannot be fully realised at the same time.
There are two (or a limited number of) options for action and whatever they choose they will commit a moral wrong. The crucial feature of a moral dilemma is not the number of actions that are available but the fact that all possible actions are morally unsatisfactory.
What role should an engineer play in influencing the outcome? What are the implications of not being involved? (This is a question we had created in addition to those provided within the case study to meet the requirements stipulated in the accompanying rubric.)
Engineers are responsible for the design of technological advancements which necessitate data storage. Although this brings many benefits, engineers need to consider the adverse impact of technological advancement such as increased water use. Students may therefore want to consider the wider implications of data storage on the environment and how these can be mitigated.
Year 2
Formulate a moral problem statement which clearly states the problem, its moral nature and who needs to act. (This is a question we had created in addition to those provided within the case study to meet the requirements stipulated in the accompanying rubric.)
An example could be: “Should the civil engineer working for DSS remain loyal to the company and defend them against accusations of causing environmental hazards, or defend their water rights and say that they will not change their behaviour”. It should be clear what the problem is, the moral values at play and who needs to act.
Stakeholder mapping: Who are all the stakeholders in the scenario? What are their positions, perspective and moral values?
Below is a non-exhaustive list of some of the relevant stakeholders and values that may come up.

Trust; privacy; accountability;autonomy.
Non-humanstakeholders
Environmental sustainability.
What are some of the possible courses of action in the situation. What responsibilities do you have to the various stakeholders involved? What are some of the advantages and disadvantages associated with each? (Reworded from case study.)
Students should provide a stance but may recognise the tensions involved. For example, at a micro level, tensions between loyalty to the profession and loyalty to the company/personal financial stability. Responsibilities to fellow employees may include the degree to which you risk their jobs by being honest. They may also feel that they should protect environmental and natural resources.
At a macro level, they may consider the need for engineers to inform decisions regarding issues that engineering and technology raise for society (e.g. increased water being needed for data storage) and listen to the aspirations and concerns of others, and challenging statements or policies that cause them professional concern.
What are the relevant facts in this scenario and what other information would you like to help inform your ethical decision making? (This is a question we had created in addition to those provided within the case study to meet the requirements stipulated in the accompanying rubric.)
Students should identify which facts within the case study are relevant in terms of making an ethical decision. In this case, some of the relevant facts may include:
Water use permissible by law (“the data centre always uses the maximum amount legally allotted to it.”)
This centre manages data which is vital for the local community, including the safe running of schools and hospitals, and that its operation requires sufficient water for cooling.
In more arid months, the nearby river almost runs dry, resulting in large volumes of fish dying.
Water levels in farmers’ wells have dropped, making irrigation much more expensive and challenging.
A new green battery plant is planned to open nearby that will create more data demand and has the potential to further increase DSS’ water use.
Obtaining water from other sources will be costly to DSS and may not be practically possible, let alone commercially viable.
Studentsshouldbeawarethatincompleteinformationhindersdecisionmakingduring ethical dilemmas, and that in some cases, further information will be needed to help inform decisions. In this case, some of the questions may pertain to:
Exactly how much water is being used and the legal rights.
Relationship between farmer and DSS/contractual obligations.
How costly irrigation is to the farmers (economic impact), as well as the knock-on impact to their business and supply chain.
How many people DSS employ and how important they are for local economy.
Detail regarding biodiversity loss and its wider impact.
How likely it is that the green battery plant will open and whether DSS is the only eligible supplier.
How much the green battery plant contract is worth to DSS.
How much water the green battery plant will use in the case that DSS get the contract.
Whether DSS is the only option for hospital and university.
What will happen if the services DSS provide to the hospital and university stop or becomes unreliable.
Year 2/Year 3
(At Year 2, students could provide options; at Year 3 they would evaluate and form a judgement.)
Make use of ethical frameworks and/or professional codes to evaluate the options for DSS both short term and long term. How do the uncertainty and assumptions involved in this case impact decision making?
Students should list plausible options. They can then analyse them with respect to different ethical frameworks (whilst we don’t necessary make use of normative ethical theories, analysis according to consequences, intention or action may be a useful approach to this). Below we have included a non-exhaustive list of options with ideas in terms of analysis.
Option
Consequences

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.

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:
Each student is assigned a role a week before the discussion.
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?

Ethical issues: Social responsibility; Human rights; Risk.
Professional situations: Legal implications; Company/organisational reputation; Conflicts with leadership/management.
Educational level: Beginner.
Educational aim: Practising Ethical Reasoning: the application of critical analysis to specific events in order to evaluate and respond to problems in a fair and responsible way.
Learning and teaching notes:
This case study puts students in the shoes of an engineer who is required to select a subcontractor to manufacture systems and parts. There are stipulations around who can be selected, among which are legal and ethical concerns around suspicions of slavery or forced labour. The engineer must navigate communication with both their supervisors and their potential subcontractor, and ultimately justify their decision.
This case study addresses two of the themes from the Accreditation of Higher Education Programmes fourth edition (AHEP4): The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills). To map this case study to AHEP outcomes specific to a programme under these themes, access AHEP 4 here and navigate to pages 30-31 and 35-37.
The case is presented in three parts. If desired, a teacher could use the Summary and Part one in isolation, but Parts two and three enable additional professional situations to be brought into consideration. The case study allows teachers the option to stop at multiple points for questions and/or activities as desired.
Learners have the opportunity to:
analyse ethical dimensions and complexities of a professional situation;
analyse risks associated with potentially questionable practice, considering short- and long-term consequences to both business and social interests;
make and justify an ethical decision;
communicate these risks and judgements to public and business audiences.
Teachers have the opportunity to:
highlight the ethical considerations within business and supply chain decisions relating to an engineering project;
introduce or reinforce concepts and methods related to risk analysis and ethical decision-making;
evaluate critical thinking, argumentation, and/or communication skills.
Autonomous Vehicle Corporation (AVC) has recently been awarded a contract to provide a bespoke design unmanned air vehicle to India. AVC is a UK certified B Corp that prides itself on maintaining the highest standards of social and environmental performance, transparency, and accountability.
A stipulation of the newly awarded contract is that at least 30% of the contract value is spent on the manufacture of sub-systems and parts from subcontractors based in India. AVC is responsible for identifying and contracting these suppliers.
After many years working as a Systems Engineer for AVC, you have been selected as the Lead Engineer for the project, responsible for the selection of the Indian suppliers. You are aware from your initial research of reports regarding slave and forced labour in the region’s manufacturing industry and are concerned that this situation might affect the project and the company. Additionally, you would personally feel uncomfortable knowing that you might contract a supplier who engaged in those practices.
Optional STOP for questions and activities:
1. Activity: To consider how AVC might be impacted from engaging a supplier that utilises slave or forced labour, chart out the viewpoints of different stakeholders, such as customers, investors, other suppliers, communities, and employees.
2. Discussion: Are there other factors besides ethical considerations that may influence your selection of supplier? What are these?
3. Discussion: How would you weigh the importance of ethical considerations, such as the use of slave or forced labour, against the other factors identified in the previous question? What information or resources might you use in guiding your weighting of these considerations?
4. Activity: Contrast the UK Engineering Council’s code of ethics with the Engineering Council of India’s Code of Ethics. How do the two differ? Which code should you be primarily guided by in this situation? Why? How might cultural expectations and norms influence what is seen as ethical?
Dilemma – Part one:
One supplier you are considering is Quality Electronics Manufacturing Pvt. Ltd. (QEM), a company based outside Naya Raipur in one of India’s poorest provinces. During a video call, QEM’s managing director assures you that they comply with a strict code of ethics and conduct all recruitment through a carefully selected list of brokers and agencies. He tells you that QEM sources raw materials from around the world, and none of their suppliers have ever been convicted of any offences relating to slavery. He invites you to tour their factory when you are in the country next month and will personally escort you to answer any questions you may have.
Optional STOP for questions and activities:
1. Activity: Does anything you have heard give you cause for concern regarding the risk of slave or forced labour at QEM in particular? Research this issue from the perspective of various sources, such as investigative journalism, academic papers, government reports, and industry publications. Do their conclusions align or differ in any significant ways? Are there any gaps in knowledge that these sources haven’t adequately covered?
2. Discussion: QEM mentions that they source raw materials from around the world. The reality of modern supply chains is that they often involve multiple complex layers of subcontractors. Does AVC have an ethical duty to consider the whole supply chain? Would this be the same if AVC were further down the supply chain? If AVC were further down the supply chain, would they have to consider the upstream elements of the supply chain? What are the business implications of considering an entire supply chain?
3. Activity: List possible contextual risk factors and potential indicators of slave and forced labour. Which are present in the case of QEM?
4. Activity and discussion: Create a set of questions you wish to answer during your visit to QEM to help assess the risk that they are engaged in the use of slave or forced labour. How will you get this information? Who will you need to talk to? What evidence would you expect to see and collect? To practise business communication, students could draft a memo to their supervisor explaining the situation and outlining their proposed course of action.
Dilemma – Part two:
During your visit to QEM’s factory, you meet with workers at all levels and you review QEM’s policies and procedures. You identify some potential risk factors that could indicate QEM is using forced labour in its workforce. You raise this with QEM’s managing director, but he responds indignantly, “QEM creates good jobs for our workers and without us they would not be able to feed their families. Your contract would allow us to sustain those jobs and create many more for the local community.”
You know that QEM is the lowest cost supplier for the work you want them to undertake, and you are under pressure to keep budgets down. You have no conclusive evidence that QEM uses forced labour. You also know that the alternative suppliers you could use are all based in regions with high employment, which means the risk of not being able to staff your work (resulting in schedule delays) is high.
Upon your return to the UK, your project manager calls you into her office and tells you she needs your decision on whether to utilise QEM by the end of the week.
Optional STOP for questions and activities:
1. Activity: Conduct a risk analysis that identifies what might be the impact of not using QEM and what might be the impact of using QEM.
2. Debate: Do you use QEM as one of your suppliers? Why, or why not? You may wish to consider your answer using the lens of uncertainty and risk.
3. Discussion: What actions could you put in place with QEM to reduce the incidence/risk of slave or forced labour in its workforce? Which of these would you recommend, and which would you require, QEM to implement as part of contracting with them? How would you enforce them, and what evidence of them being successfully implemented would you need?
Dilemma – Part three – Postscript:
If you chose to use QEM: It is now two years after you subcontracted QEM. An investigation by an NGO has uncovered the rampant use of slave and forced labour within the global electronics manufacturing industry by companies with B-Corp status. AVC is named as one of the perpetrators, and a story about workers at QEM is scheduled to run in a leading tabloid newspaper tomorrow morning. AVC has called an emergency press conference to give its side of the story.
If you chose not to use QEM: The following week, your project manager calls you into her office again. She tells you that she has just stepped out of a meeting with the board, and they are deeply concerned about spiralling costs on your project. In particular, they are concerned that you rejected QEM’s proposal in favour of another supplier who is more than twice as expensive. You have been asked to present your reasoning to the board when they reconvene shortly.
Optional STOP for activity:
1. Roleplay either the press conference or the board meeting and defend your decision.

Activity: Role-play the council meeting, with students playing different characters representing different perspectives.
Author: Cortney Holles (Colorado School of Mines, USA).
Overview:
This enhancement is for an activity found in the Dilemma Part two, Point 6 section: “Role-play the council meeting, with students playing different characters representing different perspectives.” 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.
Prompts for questions:
After discussing the case in class, and completing the stakeholder mapping activity (Dilemma Part one, Point 4 – repeated below) from the Water Wars case study, this lesson guides teachers through conducting a role-play of the council meeting scenario.
1. Discuss the stakeholder mapping activity: Who are all the characters in the scenario? What are their positions and perspectives? How can you use these perspectives to understand the complexities of the situation more fully?
2. To prepare for the council meeting role-play activity, assign students in advance to take on different stakeholder roles (randomly or purposefully), or let them self-assign based on their interests. Roles can include any of the following:
Suggestions from Stakeholder mapping activity:
Data Storage Solutions
Farmers’ union
Local Green party
Local council
Member of the public
Stakeholders who use DSS’s data storage services (such as the local hospital and schools)
Non-human stakeholders – for example, the fish, birds and insects.
Additional stakeholders to consider:
Councillors – you can choose to have them represent different political stances in your area
Environmental representatives or activists – speaking on behalf of the ecosystem and the species within it
Local citizens worried about their water supply
Local citizens in support of DSS and its economic importance in the area
DSS employee representatives – arguing on behalf of the company and their jobs
Farmers who are worried about their crops and the water supply
Clients of DSS who use data storage (hospitals, schools)
Others you or your students want to include (businesses, community groups, local politicians).
3. Before the class session in which the role-play will occur, students should research their stakeholder to get a sense of their values and motivations in regard to the case. Where no information is available, students can imagine the experiences and perspectives of the stakeholder with the goal of articulating what the stakeholder values and what motivates them to come to the council meeting to be heard on this issue. Students should prepare some statements about the stakeholder position on the water use by DSS, what the stakeholder values, and what the stakeholder proposes the solution should be. Students assigned to be council members will prepare for the role-play by learning about the conflict and writing potential questions they would want to ask of the stakeholders representing different views on the conflict.
4. In class, students prepare to role-play the council meeting by first connecting with others in the same stakeholder role (if applicable – you may have few enough students to have only one student assigned to a stakeholder) and deciding who can speak (you may want to require each student to speak or ask that one person be nominated to speak on behalf of the stakeholder group).
5. As the session begins, remind students to jot down notes from the various perspectives’ positions so there can be a debrief conversation at the end. Challenge students to consider their personal biases and position at the outset and reflect on those positions and biases at the end of the council meeting. If they were a lead member of the council, what solution would they propose or vote for?
6. As the Council Meeting begins, 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 students representing the Council members. Council members will open the meeting with their description of the matter at hand between DSS and other local parties. They set the tone for the meeting with a call for feedback from the community members. The teacher can help the Council members call up the stakeholders in turn. Each stakeholder group will have a chance to state their argument, values, and reasons for or against DSS’ water use. Each stakeholder will have an opportunity to suggest a proposed solution and Council members can engage in discussion with each stakeholder to clarify anything about their position that was unclear.
7. At the end of the meeting, the council members privately confer and then publicly vote on a resolution for the community. All students, no matter their role, end the class by reflecting on the outcome and their original position on the case. Has anything shifted in their position or rationale after the council meeting? Why or why not?
8. The whole class could then engage in a discussion about the outcome of the council meeting. Teachers could focus on an analysis of how the process went, a discussion about the persuasiveness of different values and positions, and/or an exploration of the internal thinking students went through to arrive at their positions.

Topic: Data centres’ impact on sustainable water resources.
Professional situations: Law or policy, Communication, Integrity.
Educational level: Intermediate.
Educational aim: Practise ethical judgement. Ethical Judgment is the activity of thinking about whether something has a moral attribute. Judgments involve reaching moral decisions and providing the rationale for those decisions.
Learning and teaching notes:
This case involves a situation where environmental damage may be occurring despite the mechanism causing this damage being permissible by law. The engineer at this centre of the case is to represent the company that is responsible for the potential damage, at a council meeting. It requires the engineer to weigh up various harms and goods, and make a decision that could seriously impact their own job or career. There is also a section at the end of this case study that contains technical information providing further details about the water cooling of ICT equipment.
This case study addresses two of AHEP 4’s themes: The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills). To map this case study to AHEP outcomes specific to a programme under these themes, access AHEP 4here and navigate to pages 30-31 and 35-37.
The dilemma in this case 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. The case allows teachers the option to stop at multiple points for questions and/or activities as desired.
Students have the opportunity to:
apply their ethical judgement to a case study relating to environmental sustainability;
judge the societal impact of a technical solution to a complex problem;
identify and analyse objective and subjective risk;
consider the concept of consensus;
communicate the risks and judgements to technical and non-technical audiences.
Teachers have the opportunity to:
introduce environmental ethics concepts related to water;
highlight the components and processes of risk analysis;
integrate technical content related to heat transfer and flow;
informally evaluate students’ critical thinking and communication skills.
The company Data Storage Solutions (DSS) has built a large data centre on land that was historically used for agriculture and owned by a farming operation. DSS was incorporated as a subsidiary of the farming company so that it could retain the water rights that were attached to the property. This ensured access to the large amount of water needed to cool their servers. This centre manages data from a variety of sources including the local hospital and university.
When the property was used as a farm, the farming operation never used its full allocation of water. Now, the data centre always uses the maximum amount legally allotted to it. For the rainy half of the year, this isn’t a problem. However, in more arid months, the nearby river almost runs dry, resulting in large volumes of fish dying. Other farmers in the area have complained that the water level in their wells has dropped, making irrigation much more expensive and challenging.
Dilemma – Part one:
You are a civil engineer working for DSS and have been requested by your boss to represent the company at a forthcoming local council meeting where the issue will be discussed. Your employer is sending you to justify the company’s actions and defend them against accusations of causing an environmental hazard in the local area which is reducing the water table for farmers and affecting local biodiversity. Your boss has told you that DSS has a right to the water and that it does not intend to change its behaviour. This meeting promises to be a contentious one as the local Green party and farmers’ union have indicated that they will be challenging the company’s water usage. How will you prepare for the meeting?
Optional STOP for questions and activities:
1. Discussion: Personal values – What is your initial position on the issue? Do you see anything wrong with DSS’s water use? Why, or why not?
2. Discussion: Professional responsibilities – What ethical principles and codes of conduct are relevant to this situation?
3. Activity: Define and identify the relevant data you should compile to take to the meeting. What information do you need in order to be prepared?
4. Activity: Stakeholder mapping – Who are all the characters in the scenario? What are their positions and perspectives? How can you use these perspectives to understand the complexities of the situation more fully? Examples include:
Data Storage Solutions
Farmers’ union
Local Green party
Local council
Member of the public
Stakeholders who use DSS’s data storage services (such as the local hospital and schools)
Non-human stakeholders – for example, the fish, birds and insects.
5. Activity: Undertake a technical activity such as civil and / or electronic engineering related to the measurement of stream flow and calculating data centre cooling needs.
Dilemma – Part two:
As you prepare for the meeting, you reflect on several competing issues. For instance, you are an employee of DSS and have a responsibility to represent its interests, but can see that the company’s actions are environmentally harmful. You appreciate that the data centre is vital for the local community, including the safe running of schools and hospitals, and that its operation requires sufficient water for cooling. Your boss has told you that you must not admit responsibility for any environmental damage or biodiversity loss. You also happen to know that a new green battery plant is planning to open nearby that will create more data demand and has the potential to further increase DSS’s water use. You know that obtaining water from other sources will be costly to DSS and may not be practically possible, let alone commercially viable. What course of action will you pursue?
Optional STOP for questions and activities:
1. Activity: Debate what course of action you should take. Should you take the company line despite knowing about the environmental impacts? Should you risk your reputation or career? What responsibilities do you have to fellow employees, the community, and the environment?
2. Activity: Risk analysis – What are the short- and long- term burdens and benefits of each course of action? Should environmental concerns outweigh others? Is there a difference between the environment locally and globally?
3. Activity and discussion: Read Sandra Postel’s case for a Water Ethic, and consider New Zealand’s recent legislation that gives a rainforest the same rights as a human. With this in mind, does the stream have a right to thrive? Do the fish have a right to a sustainable environment? Are humans ultimately at risk here, or just the environment? Does that answer change your decision? Why?
4. Activity: Prepare a statement for the council meeting. What will you argue?
You could take the company line and refuse to consider any compromise. After all, you have the legal right to the water.
You could take the environmentalists’ side and go against your boss, admitting that the company is aware of the environmental damage, but that they refuse to do anything about it.
You could work up a proposal for obtaining the water from a different source, or alternative technical solutions, despite not having the backing of your boss.
Are there other alternatives available to you?
5. Activity: The students should interrogate the pros and cons of each possible course of action including the ethical, the practical, the cost, the local relationship and the reputational damage implications. They should decide on their own preferred course of action and explain why the balance of pros and cons is preferable to other options.The students may wish to consider this from other perspectives, such as:
What actions are available to individuals at each level of hierarchy in DSS – for example, a junior engineer compared to a senior manager?
What would the best outcome be if the business or cost considerations were of no consequence?
What course of action would be taken if different perspectives were taken as the priority – for example, if the environmental perspective were the main priority what action would be taken, compared with action taken if the cost to the local economy were the main priority?
What are the wider implications of data storage on the environment and how can these be mitigated?
What could be other direct and indirect benefits of data centres, other than being a place to house data – for example, is there an opportunity for the waste heat from DSS to become a benefit? (Use theThe city where the internet warms people’s homes article.)
What are the possible solutions open to you?
Are there any short-term solutions versus longer-term solutions?
7. Activity: Allow students to reflect on how this case study has enabled them to see the situation from different angles, and whether this has helped them to understand the ethical concerns and come to an acceptable conclusion.
Annex – Accompanying technical information:
ICT equipment generates heat and so most devices must have a mechanism to manage their temperature. Drawing cool air over hot metal transfers heat energy to that air, which is then pushed out into the environment. This works because the computer temperature is usually higher than the surrounding air. There are several different mechanisms for data centre cooling, but the general approach involves chillers reducing air temperature by cooling water – typically to 7–10 °C, which is then used as a heat transfer mechanism. Some data centres use cooling towers where external air travels across a wet media so that the water evaporates. Fans expel the hot, wet air and the cooled water is recirculated. Other data centres use adiabatic economisers – where water is sprayed directly into the air flow, or onto a heat exchange surface, thereby cooling the air entering the data centre. With both techniques the evaporation results in water loss. A small 1 MW data centre using one of these types of traditional cooling can use around 25.5 million litres of water per year. Data centre water efficiency deserves greater attention. Annual reports show water consumption for cooling directly paid for by the operator, so there is an economic incentive to increase efficiency. As the total energy share of cooling has fallen with improving PUEs (Power Usage Effectiveness metric), the focus has been on electricity consumption, and so water has been a low priority for the industry. However, the largest contributor to the water footprint of a data centre is electricity generation. Where data centres own and operate the entire facility, there is more flexibility for exploring alternative sources of water, and different techniques for keeping ICT equipment cool.
