Learning and teaching notes:  

This case study involves an engineer who has to weigh personal values against professional codes of conduct when acting in the wake of the climate crisis. This case study allows students to explore motivations and justifications for courses of action that could be considered morally right but legally wrong.  

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 dilemma in this case is presented in three parts. If desired, a teacher can use Part one in isolation, but Parts two and three develop and complicate the concepts presented in Part one to provide for additional learning. The case study allows teachers the option to stop at multiple points for questions and/or activities, as desired.

Summary: 

Kelechi is a civil engineer in a stable job, working on the infrastructure team of a County Council that focuses on regeneration and public realm improvements. Kelechi grew up in an environment where climate change and its real impacts on people was discussed frequently. She was raised with the belief that she should live as ethically as possible, and encourage others to consider their impact on the world. These beliefs were instrumental in leading Kelechi into a career as a civil engineer, in the hope that she could use her skills and training to create a better world. In one of her engineering modules at university, Kelechi met Amanda, who encouraged her to join a student group pushing for sustainability within education and the workplace. Kelechi has had some success with this within her own job, as her employer has been willing to participate in ongoing discussions on carbon and resilience, and is open to implementing creative solutions.  

But Kelechi is becoming frustrated at the lack of larger scale change in the wake of the climate emergency. Over the years she has signed petitions and written to her representatives, then watched in dismay as each campaign failed to deliver real world carbon reduction, and as the government continued to issue new licenses for fossil fuel projects. Even her own employers have failed to engage with climate advocates pushing for further changes in local policy, changes that Kelechi believes are both achievable and necessary. Kelechi wonders what else she can do to set the UK – if not the world – on a path to net zero. 

 

Dilemma – Part one: 

Scrolling through a news website, Kelechi is surprised to see a photo of her friend and ex-colleague Amanda, in a report about climate protesters being arrested. Kelechi messages Amanda to check that she’s ok, and they get into a conversation about the protests. Amanda is part of a climate protest group of STEM professionals that engages in non-violent civil disobedience. The group believes that by staging direct action protests they can raise awareness of the climate emergency and ultimately effect systemic change.  

Amanda tries to convince Kelechi to join the group and protest with them. Amanda references the second principle of the Statement of Ethical Principles published by the Engineering Council and the Royal Academy of Engineering: “Respect for life, law, the environment and public good.” Amanda believes that it is ok to ignore the tenet about respect for the law in an effort to safeguard the other three, and says that there have been plenty of unjust laws throughout history that have needed to be protested in order for them to be changed for the public good. She also references another part of the Statement: that engineers should ”maximise the public good and minimise both actual and potential adverse effects for their own and succeeding generations”. Amanda believes that by protesting she is actually fulfilling her duty to uphold these principles.  

Kelechi isn’t sure. She has never knowingly broken the law before, and is worried about being arrested. Kelechi consults her friend Max, who is a director of a professional engineering institution, of which Kelechi is a member. Max, whilst she has some sympathies for the aims of the group, immediately warns Kelechi away from the protests. “Forget about being arrested; you could lose your job and end your career.”  

 

Optional STOP for questions and activities: 

1. Discussion: What personal values will Kelechi have to weigh in order to decide whether or not to take part in a civil disobedience protest? 

2. Discussion: Consider the tenet of the Statement of Ethical Principles “Respect for life, law, the environment and public good.” To what extent (if at all) do the four tenets of this ethical principle come into conflict with one another in this situation? Can you think of other professional situations in which they might conflict? 

3. Discussion: Is breaking the law always unethical? Are there circumstances when breaking the law might be the ethical thing to do in the context of engineering practice? What might these circumstances be? 

4. Discussion: To what extent (if at all) does the content of the Statement of Ethical Principles make a case for or against being part of a protest where the law is broken?  

5. Discussion: Following on from the previous question – does it make a difference what is being protested, if a law is broken? For example, is protesting fossil fuels that lead to climate change different from protesting unsafe but legal building practices, such as cladding that causes a fire risk? Why? 

6. Activity: Research other professional codes of engineering: do these have clear guidelines for this situation? Assemble a bibliography of other professional codes or standards that might be relevant to this scenario. 

7. Discussion: What are the potential personal and professional risks or benefits for Kelechi if she takes part in a protest where the law is broken? 

8. Discussion: From a professional viewpoint, should Kelechi take part in the protest? What about from a personal viewpoint? 

 

Dilemma – Part two: 

After much deliberation, Kelechi decides to join the STEM protest group. Her first protest is part of a direct action to blockade a busy London bridge. To her own surprise, she finds herself volunteering to be one of two protesters who will climb the cables of the bridge. She is reassured by the risk assessment undertaken by the group before selecting her. She has climbing experience (although only from her local leisure centre), and safety equipment is provided.  

On the day of the protest, Kelechi scales the bridge. The police are called and the press arrive. Kelechi stays suspended from the bridge for 36 hours, during which time all traffic waiting to cross the bridge is halted or diverted. Eventually, Kelechi is convinced that she should climb down, and the police arrest all of the protesters.  

Later on, Kelechi is contacted by members of the press, asking for a statement about her reason for taking part in the protest. Kelechi has seen that press coverage of the protest is so far overwhelmingly negative, and poll results suggest that the majority of the public see the protesters’ actions as selfish, inconvenient, and potentially dangerous, although some have sympathy for their cause. “What if someone died because an ambulance couldn’t use the bridge?” asks someone via social media. “What about the five million deaths a year already caused by climate change?” asks another, citing a recent news article.  

Kelechi would like to take the opportunity to make her voice heard – after all, that’s why she joined the protest group – but she isn’t sure whether she should mention her profession. Would it add credibility to her views? Or would she be lambasted because of it? 

 

Optional STOP for questions and activities: 

1. Discussion: What professional principles or codes is Kelechi breaking or upholding by scaling the bridge?  

2. Activity: Compare the professional and ethical codes for civil engineers in the UK and elsewhere. How might they differ in their guidance for an engineer in this situation?  

3. Activity: Conduct a risk assessment for a) the protesters who have chosen to be part of this scenario, and b) members of the public who are incidentally part of this scenario. 

4. Discussion: Who would be responsible if, as a direct or indirect result of the protesters blocking the bridge, a) a member of the public died, or b) a protester died? Who is responsible for the excess deaths caused directly or indirectly by climate change? 

5. Discussion: How can Kelechi best convey to the press and public the quantitative difference between the short-term disruption caused by protests and the long-term disruption caused by climate change? 

6. Discussion: Should Kelechi give a statement to the press? If so, should she discuss her profession? What would you do in her situation? 

7. Activity: Write a statement for Kelechi to release to the press. 

8. Discussion: Suggest alternative ways of protesting that would have as much impact in the news but potentially cause less disruption to the public. 

 

Dilemma – Part three: 

Kelechi decides to speak to the press. She talks about the STEM protest group, and she specifically cites the Statement of Ethical Principles as her reason for taking part in the protest: “As a professional civil engineer, I have committed to acting within our code of ethics, which requires that I have respect for life, the environment and public good. I will not just watch lives be destroyed if I can make a difference with my actions.”  

Whilst her statement gets lots of press coverage, Kelechi is called out by the media and the public because of her profession. The professional engineering institution of which Kelechi is a member receives several complaints about her actions, some from members of the public and some from other members of the institution. “She’s bringing the civil engineering profession into disrepute,” says one complaint. “She’s endangering the public,” says another. 

It’s clear that the institution must issue a press release on the situation, and it falls to Kelechi’s friend Max, as a director of the institution, to decide what kind of statement to put out, and to recommend whether Kelechi’s membership of the institution could – or should – be revoked. Max looks closely at the institution’s Code of Professional Conduct. One part of the Code says that “Members should do nothing that in any way could diminish the high standing of the profession. This includes any aspect of a member’s personal conduct which could have a negative impact upon the profession.” Another part of the Code says: “All members shall have full regard for the public interest, particularly in relation to matters of health and safety, and in relation to the well-being of future generations.” 

As well as the institution’s Code of Conduct, Max considers the historic impact of civil resistance in achieving change, and how those engaging in such protests – such as the suffragettes in the early 1900s – could be viewed negatively at the time, whilst later being lauded for their efforts. Max wonders at what point the tide of public opinion begins to turn, and what causes this change. She knows that she has to consider the potential impacts of the statement that she puts out in the press release; how it might affect not just her friend, but the institution’s members, other potential protesters, and also her own career.  

 

Optional STOP for questions and activities: 

1. Discussion: Historically, has civil resistance been instrumental or incidental in achieving systemic change? Research to find out if and when engineers have been involved in civil resistance in the past. 

2. Discussion: Could Kelechi’s actions, and the results of her actions, be interpreted as having “a negative impact on the profession”? 

3. Discussion: Looking at Kelechi’s actions, and the institution’s code of conduct, should Max recommend that Kelechi’s membership be revoked? 

4. Discussion: Which parts of the quoted code of conduct could Max emphasise or omit in her press release, and how might this affect the tone of her statement and how it could be interpreted? 

5. Activity: Debate which position Max should take in her press release: condemning the actions of the protesters as being against the institution’s code of conduct; condoning the actions as being within the code of conduct; remaining as neutral as possible in her statement. 

6. Discussion: What are the wider impacts of Max’s decision to either remain neutral, or to stand with or against Kelechi in her actions?  

7. Activity: Write a press release for the institution, taking one of the above positions. 

8. Discussion: Which other authorities or professional bodies might be impacted by Max’s decision? 

9. Discussion: What are the potential impacts of Max’s press release on the following stakeholders, and what decisions or actions might they take because of it? Kelechi; Kelechi’s employer; members of the STEM protest group; the institution; institution members; government policymakers; the media; the public; the police; fossil fuel businesses; Max’s employers; Max herself.

Learning and teaching notes: 

This case study requires a newly appointed engineer to make a decision about whether or not to sell unsuitable equipment to a developing country. Situated in Ghana, the engineer must weigh perspectives on environmental ethics that may differ from those informed by a different cultural background, as well as navigate unfamiliar workplace expectations. 

The engineer’s own job security is also at stake, which may complicate decision-making. As a result, this case has several layers of relations and potential value-conflicts. These include values that underlie assumptions held about honesty, integrity, the environment and its connection to human life and services. 

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. 

This case study 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 study allows teachers the option to stop at multiple points for questions and/or activities as desired.

Dilemma – Part one: 

You have just graduated from university as a mechanical engineer and you are starting your first job as a sales engineer for JCD Engineering, a company that designs and manufactures pumping equipment. JCD has recently expanded operations in sub-Saharan Africa and you took the job because you were excited for the opportunity to travel and work in a country and culture different from your own.  

For your first project, you have been asked to put together quite a large bid for a water pumping aid project for some farms in northern Ghana. It just so happens that there is a trade show being held in Accra, so your manager has suggested you attend the show with a colleague to help on the company stand and combine this with a site visit to where the pumping equipment is to be installed. A representative from the aid organisation agrees to drive you to where the project will be sited before the trade show takes place. 

On arrival in Ghana, you are met by the rep to take you on your journey up country. This is your first visit to a developing country; you are excited, a little apprehensive and quite surprised by disorganisation at the airport, poor infrastructure, and obvious poverty in the villages up country. Still, you immediately see the difference that water pump installation could make to improve quality of life in villages. After two days of travelling, you eventually arrive at the village where the project JCD is bidding on will be situated. You are surprised to hear that the aid rep is quite cynical about engineering aid projects from the UK; this is because many have failed and she hopes that this won’t be another one. She is very busy and leaves you with local school teacher Amadou, who will host you during your stay and act as your interpreter. 

The local chief, farmers, and their families are very excited to see you and you are taken aback by the lavish food, dancing, and reception that they have laid on especially for you. You exchange social media contacts with Amadou, who you understand has been instrumental in winning this contract. You get excited about working with Amadou on this project and the prospect of improving the livelihoods of the locals with better access to clean water. 

After some hours you get shown some of the existing pumping equipment, but you don’t recognise it and it has obviously been left idle for some time and looks to be in a poor state. The farmers appear confused and are surprised that you aren’t familiar with the pumps. They explain that the equipment is from China and was working well for many years. They understand how it operates and have even managed to repair some of the fittings in local workshops, but there are now key parts they have been waiting many months for and they assume that you have brought them with you. 

You try to explain through Amadou that there has been some misunderstanding and that you don’t have the spares but will be quoting for replacement equipment from your company in the UK. This is not what the farmers want to hear and the mood changes. They have spent many years getting to know this kit and now they can even locally fabricate some of the parts. Why would you change it all now? The farmers start shouting and Amadou takes you to one side and suggests you should respond by offering them something in return. 

What should you offer them? 

 

Optional STOP for questions and activities: 

1. Discussion: What is your initial reaction to the miscommunication? Does it surprise you? What might your initial reaction reveal to you about your own perspectives and values? 

2. Discussion: What is your initial reaction to the reception given to you? Does it surprise you? What might your initial reaction reveal to you about your own perspectives and values? 

3. Activity: Technical integration – undertake an electrical engineering technical activity related to water pumps and their power consumption against flow rates and heads. 

4. Discussion and activity: List the potential benefits and risks to implementing water pump technology compared to traditional methods of water collection. Are these benefits and risks the same no matter which country they are implemented in? 

5. Activity: Research water pumping in developing countries. What are the main technical and logistical issues with this technology? Are there any cultural issues to consider?  

6. Activity: This activity is related to optional pre-readings on environmental ethics. Consider how your perspective is related to the following environmental values, and pair/share or debate with a peer. 

 

Dilemma – Part two: 

You reluctantly backtrack a little on what you said earlier and convince Amadou and the farmers that you will be able to sort something out. Back in Accra at the local trade show, you manage to source only a few spares as a quick fix since you had to pay for them yourself without your colleague noticing. The aid representative agrees to take them up country next time she travels. 

You arrive back in the UK and begin to prepare the JCD bid. You are aware that the equipment from your company is very different to the Chinese kit that the farmers already have. It is designed to run on a different voltage and uses different pipe gauges throughout for the actual water pumping. The locally fabricated spares will definitely not connect to the JCD components you will be specifying. 

You voice your concerns to your manager about the local situation but your manager insists that it is not your problem and the bid will not win if it is not competitive. Sales in your department are not good at the moment, and after all you are a new employee on probation and you want to make a good first impression. 

Having further investigated some comments Amadou made on the trip, you discover that the water table has dropped by several metres in this part of Ghana over the last five years and you realise that the equipment originally quoted for might not even be up to the job! 

 

Optional STOP for questions and activities: 

1. Discussion: Should you disclose these newly discovered concerns about the water table height or keep quiet? 

2. Discussion: Do you continue to submit the bid for equipment that you know may be totally inappropriate? Why, or why not? 

3. Activity: Role-play a conversation between the engineer and the JCD manager about the issues that have been discovered. 

4. Discussion and activity: Research levels of the water table in West Africa and how they have changed over the last 50 years. Is there a link here to climate change? What other factors may be involved? 

5. Discussion: Environmental ethics deals with assumptions that are often unstated, such as the obligation to future generations. Some people find that our obligation is greater to people who exist at this moment than to those that don’t yet exist. Do you agree or disagree with this position? Why? Can we maintain an obligation to future generations while simultaneously saying that this must be weighed against the obligations in the here and now? 

6. Activity: Both cost-benefit and value trade-off analyses are valuable approaches to consider in this case. Determine the possible courses of action and undertake both types of analysis for each position by considering both short- and long-term consequences. (Use the Mapping actors and processes article to help with this activity.) 

7. Activity: Using reasoning and evidence, create arguments for choosing one of the possible courses of action. 

8. Activity: Use heuristics to analyse possible courses of action. One heuristic is the Environmental ethics decision making guide. Another is the 7-step guide to ethical decision-making.

Case enhancement: Water wars: managing competing water rights

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:

Additional stakeholders to consider:

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.

Case Enhancement: Choosing to install a smart meter

Activity: Technical integration – Practical investigation of electrical energy.

Author: Mr Neil Rogers (Independent Scholar).

 

Overview:

This enhancement is for an activity found in the Dilemma Part two, Point 1 section of the case: “Technical integration – Undertake an electrical engineering technical activity related to smart meters and the data that they collect.”

This activity involves practical tasks requiring the learner to measure parameters to enable electrical energy to be calculated in two different scenarios and then relate this to domestic energy consumption. This activity will give technical context to this case study as well as partly address two AHEP themes:

This activity is in three parts. To fully grasp the concept of electrical energy and truly contextualise what could be a remote and abstract concept to the learner, it is expected that all three parts should be completed (even though slight modifications to the equipment list are acceptable).

Learners are required to have basic (level 2) science knowledge as well as familiarity with the Multimeters and Power Supplies of the institution.

Learners have the opportunity to:

Teachers have the opportunity to:

 

Suggested pre-reading:

To prepare for these practical activities, teachers may want to explain, or assign students to pre-read articles relating to electrical circuit theory with respect to:

 

Learning and teaching resources:

 

Activity: Practical investigation of electrical energy:

Task A: Comparing the energy consumed by incandescent bulbs with LEDs.

1. Power in a circuit.

By connecting the bulbs and LEDs in turn to the PSU with a meter in series:

a. Compare the wattage of the two devices.

b. On interpretation of their data sheets compare their luminous intensities.

c. Equate the quantity of each device to achieve a similar luminous intensity of approximately 600 Lumens (a typical household bulb equivalent).

d. now equate the wattages required to achieve this luminous intensity for the two devices.

 

2. Energy = Power x Time.

The units used by the energy providers are kWh:

a. Assuming the devices are on for 6 hours/day and 365 days/year, calculate the energy consumption in kWh for the two devices.

b. Now calculate the comparative annual cost assuming 1 kWh = 27p ! (update rate).

 

3.  Wider implications.

a. Are there any cost-benefit considerations not covered?

b. How might your findings affect consumer behaviour in ways that could either negatively or positively impact sustainability?

c. Are there any ethical factors to be considered when choosing LED lightbulbs? For instance, you might investigate minerals and materials used for manufacturing and processing and how they are extracted, or end-of-life disposal issues, or fairness of costs (both relating to production and use).

 

Task B: Using a plug-in power meter.

1. Connect the power meter to a dishwasher or washing machine and run a short 15/30 minute cycle and record the energy used in kWh.

2. Connect the power meter to a ½ filled kettle and turn on, noting the instantaneous power (in watts) and the time taken. Then calculate the energy used and compare to the power meter.

3. Connect the power meter to the fan heater and measure the instantaneous power. Now calculate the daily energy consumption in kWh for a fan heater on for 6 hours/day.

4. Appreciation of consumption of electrical energy over a 24 hour period (in kWh) is key. What are the dangers in reading instantaneous energy readings from a smart meter?

 

Task C: Calculation of typical domestic electrical energy consumption.

1. Using the list of items in Appendix A, calculate the typical electrical energy usage/day for a typical household.

2. Now compare the electrical energy costs per day and per year for these three suppliers, considering how suppliers source their energy (i.e. renewable vs fossil fuels vs nuclear etc).

 

Standing charge cost / day Cost per kWh Cost / day Cost / year
A) 48p 28p
B) 45p 31p
C) 51p 27p

 

3. Does it matter that data is collected every 30 minutes by your energy supplier? What implications might changing the collection times have?

4. With reference to Sam growing marijuana in the case, how do you think this will show up in his energy bill?

 

Appendix A: Household electrical devices power consumption:

Typical power consumption of electrical devices on standby (in Watts).

Wi-Fi router 10
TV & set top box 20
Radios & alarms 10
Dishwasher  5
Washing machine  5
Cooker & heat-ring controls 10
Gaming devices 10
Laptops x2 10

 

Typical consumption of electrical devices when active (in Watts) and assuming Gas central heating.

TV & set top box (assume 5 hours / day) 120
Dishwasher (assume 2 cycles / week) Use calculated
Washing machine (assume 2 cycles / week) Use calculated
Cooking (oven, microwave etc 1 hour / day) 1000
Gaming devices (1 hour / day) 100
Laptop ( 1 hour / day) 70
Kettle (3 times / day) Use calculated
Heating water pump (2 hours / day) 150
Electric shower (8 mins / day) 8000

Engineering disciplines: Civil engineering, Electronic engineering.

Ethical issues: Sustainability, Respect for environment, Future generations, Risk, Societal impact.

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 4 here and navigate to pages 30-31 and 35-37.

Summary:

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

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?

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:

6. Activity: Role-play the council meeting, with students playing different characters representing different perspectives.

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.

Topic: Smart meters for responsible everyday energy use.

Engineering disciplines: Electrical engineering

Ethical issues: Integrity, Transparency, Social responsibility, Respect for the environment, Respect for the law

Professional situations: Communication, Privacy, Sustainability

Educational level: Beginner

Educational aim: To encourage ethical motivation. Ethical motivation occurs when a person is moved by a moral judgement, or when a moral judgement is a spur to a course of action. 

 

Learning and teaching notes:

This case is an example of ‘everyday ethics’. A professional engineer must give advice to a friend about whether or not they should install a smart meter. It addresses issues of ethical and environmental responsibility as well as public policy, financial burdens and data privacy. The case helps to uncover values that underlie assumptions that people hold about the environment and its connection to human life and services. It also highlights the way that those values inform everyday decision-making.

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 4 here and navigate to pages 30-31 and 35-37.

The dilemma in this case is presented in three parts that build in complexity. If desired, a teacher can use Part one in isolation, but Part two and Part three develops and complicates the concepts presented in Part one in order to provide additional learning. The case allows teachers the opportunity to stop at various points to pose questions and/or set activities.

Summary – Part one:

Sam and Alex have been friends since childhood. As they have grown older, they have discovered that they hold very different political and social beliefs, but they never let these differences of opinion get in the way of a long and important friendship. In fact, they often test their own ideas against each other in bantering sessions, knowing that they are built on a foundation of respect.

Sam works as an accountant and Alex has become an environmental engineer. Perhaps naturally, Alex often asks Sam for financial advice, while Sam depends on Alex for expert information related to sustainability and the environment. One day, knowing that Alex is knowledgeable about the renewable energy industry and very conscious of the impact of energy use at home, Sam messages Alex to say he is getting pressure from his energy company to install a smart meter.

Sam has been told that smart metering is free, brings immediate benefits to customers by helping them to take control of their energy usage, and is a key enabler for the transition away from fossil fuels use and towards the delivery of net zero emissions by 2050. Smart meters give consumers near real-time information on energy use, and the associated cost, enabling them to better manage their energy use, save money and reduce emissions. A further benefit is that they could charge their electric car far more cheaply using a smart meter on an overnight tariff.

Yet Sam has also read that smart meters ‘go dumb’ if customers switch providers and, as a pre-payment customer, this option may not be available with a smart meter. In addition, Sam suspects that despite claims that the smart meter roll out is free, the charge is simply being passed on to customers through their energy bills instead. Alex tries to give Sam as much good information as possible, but the conversation ends with the decision unresolved.

 

Optional STOP for questions and activities: 

1. Discussion and activity: Personal values – We know that Sam and Alex have different ideas and opinions about many things. This probably stems from a difference in how they prioritise values. For instance, valuing transparency over efficiency, or sustainability over convenience. Using this values activity as a prompt, what personal values might be competing in this particular case?

2. Discussion and activity: Everyday ethics – Consider what values are involved in your everyday choices, decisions, and actions. Write a reflective essay on three events in the past week that, upon further analysis, have ethical components.

3. Discussion: Professional values – Does Alex, as an environmental engineer, have a responsibility to advocate installing smart meters? If so, does he have more responsibility than a non-engineer to advocate for this action? Why, or why not?

4. Discussion: Wider impact – Are there broader ethical issues at stake here?

5. Activity: Role-play a conversation between Sam and Alex that includes what advice should be given and what the response might be.

 

Dilemma – Part two:

After getting more technical information from Alex, Sam realises that, with a smart meter, data on the household’s energy usage would be collected every 30 minutes.  This is something they had not anticipated, and they ask a number of questions about the implications of this. Furthermore, while Sam has already compared tariffs and costs as the main way to choose the energy provider, Alex points out that different providers use different energy sources such as wind, gas, nuclear, coal, and solar. Sam is on a tight budget but Alex explains that the cheaper solution is not necessarily the most environmentally responsible choice. Sam is frustrated: now there is something else to consider besides whether or not to install the smart meter.

 

Optional STOP for questions and activities:  

1. Activity: Technical integration – Undertake an electrical engineering technical activity related to smart meters and the data that they collect.

2. Activity: Research what happens with the data collected by a smart meter. Who can access this data and how is privacy protected? How does this data inform progress towards the energy transition from fossil fuels?

3. Activity: Research different energy companies and their approach to responsible energy sourcing and use. How do these companies communicate that approach to the public? Which company would you recommend to your friend and why?

4. Activity: Cost-benefit analysis – Sometimes the ethical choice is the more expensive choice. How do you balance short- and long-term benefits in this case? When, if ever, would it be ethically right to choose energy from non-renewable sources? How would this choice differ if the context being considered was different? For example, students could think about responsible energy use in industrialised economies versus the developing world and energy justice.

 

Dilemma – Part three:

Following this exchange with Sam, Alex becomes aware that one of the main obstacles in energy transition concerns communication with the public. Ideally, Alex wants to persuade family and other friends to make more responsible choices; however, it is clear that there are many more factors involved than can be seen in one glance. This includes what kinds of pressure is put on consumers by companies and the government. Alex begins to reflect on how policy drives what engineers think and do, and joins a new government network on Engineering in Policy.  

Alex and Sam meet up a little while later, and Sam announces that yes, a smart meter has been installed. At first Alex is relieved, but then Sam lets it slip that they are planning to grow marijuana in their London home. Sam asks whether this spike in energy use will be picked up as abnormal by a smart meter and whether this would lead to them being found out.

 

Optional STOP for questions and activities:  

1. Discussion: Personal values – What are the ethics involved in trying to persuade others to make similar choices to you?

2. Discussion and activity: Legal responsibility – What should Alex say or do about Sam’s disclosure? Role-play a conversation between Sam and Alex.

3. Discussion: Professional responsibility – What role should engineers play in setting and developing public policy on energy?

4. Activity: Energy footprint – Research which industries use the most energy and, on a smaller scale, which home appliances use the most energy.

Keywords: Ethical principles; Code of conduct; Engineering professionals; Ethical decision-making; Ethical behaviour.

Who is this article for?: This article should be read by educators at all levels in higher education who wish to integrate ethics into the engineering and design curriculum or module design. It will also help to prepare students with the integrated skill sets that employers are looking for.

 

Premise:

The Statement of Ethical Principles published by the Engineering Council and the Royal Academy of Engineering in 2005 (revised in 2017) contains the recommendations to which all UK engineers should comply. It sets out four fundamental principles that all engineering professionals should aspire to follow in their working habits and relationships.

At the launch of the revised document, the Chair of the Engineering Council said “The profession needs to ensure that the principles are embedded at all stages of professional development for engineers and those technicians, tradespeople, students, apprentices and trainees engaged in engineering.”

These principles are based on the premise that engineering professionals work to enhance the wellbeing of society, and in so doing they are required to maintain and promote high ethical standards, as well as to challenge unethical behaviour. The principles are the foundation for making decisions when faced with an ethical dilemma in engineering.

 

The four principles:

The code defines four fundamental principles of ethical behaviour: Honesty and integrity; Respect for life, law, the environment and public good; Accuracy and rigour; and Leadership and communication.

The requirement for engineers to embody honesty and integrity is based on the expectation that engineers can be trusted. It seeks to position the engineering community as one that possesses the respect and confidence of the public. People should feel confident that the word of an engineer is a reliable one, and that decisions taken by engineers are fair and without compromise or conflict.

Respect for life, law, the environment and public good demands that engineers are law-abiding and have the public’s best interests at heart. This allows people to feel safe when they drive over bridges, fly in aircrafts, and use electrical equipment. It reassures them that engineering designs have been tested, are legally compliant, and that the engineer puts, above all else, the wellbeing of the public, future generations, other members of the profession, and the environment in which we live. This principle also covers the protection of data and privacy of the public.

Accuracy and rigour ensures that engineers are trained, competent and knowledgeable, and that they do not pass themselves off as experts in areas where they are not competent. It requires that engineers keep their knowledge up-to-date, and share their knowledge and understanding with others in their profession. It calls for engineers to take a broad approach to problem-solving, considering a variety of external factors which may influence the risks of any project.

And finally, the principle of leadership and communication ensures that engineers lead by example, that diversity and inclusion are valued, and that people are treated fairly and with respect. It is concerned with the impact of engineering on society in the broadest sense – with how the public sees engineering and how engineering addresses public, social and environmental justice concerns. It requires engineers to be considerate and truthful when acting in a professional capacity, and to raise concerns where necessary.

These four principles underpin professional codes of conduct for engineers, and they provide guidance on how ethical decisions should be made, giving a set of values against which engineers can behave.

 

Using the principles to unpick right from wrong and make the best decision:

While these principles can form a useful basis for ethical decision-making within engineering, it is often the case that conflicts arise that prevent the decision pathway from being straightforward, when there is no obvious right or wrong answer. There may be other principles that need to be considered, relating to the organisation or the institution that the engineer is working for. Furthermore, there may be other considerations associated with a person’s religion, culture or belief system. We shouldn’t forget that other constraints such as cost and time will also impact on the possible options available.

So, decision-making in engineering is rarely straightforward. It is not like a mathematical equation with right and wrong answers, but rather with degrees of rightness, balances of pros and cons and, often, with some costs incurred for the sake of a greater good. Various tools and frameworks exist to help the decision-maker with ethical problems. Probably the simplest logical method considers each of the possible solutions against the ethical principles that are to be complied with. These can then be considered in relation to the stakeholders affected, and a list of pros and cons can be developed. They can even be scored and weighted.

What if a decision is required quickly? How do we ensure that we are likely to make the best one? These questions are partly due to the values that we subscribe to as engineers, and as individuals. They become embedded in our subconsciousness through our training and practice. When decisions need to be made in a hurry, we rely on heuristics, or simple rules or instincts that feel consistent with the ethical knowledge and expertise that we have built up during our career. These heuristics, however, are subject to cognitive biases – psychological patterns of thought that divert us from purely rational approaches. Being aware of these biases can help to minimise or compensate for them.

 

Conclusion:

Engineers should utilise the Statement of Ethical Principles and knowledge of the specific context they are working in, to make the best decisions on the situation or dilemmas at hand. Ultimately, decisions that we make as a professional engineer are our individual responsibility, and whatever decision results, we should be prepared to justify and stand by them, knowing that we have taken these in good faith and for the right reasons. Ethical decision-making can be practised throughout an engineer’s education by using a variety of case studies to explore a range of scenarios an engineer could face. The Royal Academy of Engineering and Engineering Professors’ Council’s Engineering ethics case studies can be used for this.
