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: Power-to-food technologies

Activity: An ethical evaluation of the technology and its impacts.

Author: Dr Fiona Truscott (UCL).

 

Overview:

This enhancement is for an activity found in the Dilemma Part one, Point 1 section of the case: “Identify different aspects of the production process where ethical concerns may arise, from production to delivery to consumption.” Below are 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.

In this group activity, students will act as consultants brought in by the Power to Food team to create an ethical evaluation of the technology and any impacts it may have throughout its lifetime. The aim here is for students to work together to discuss the potential ethical issues at each stage of the production process as well as thinking about how they might be addressed. Groups will need to do research, either in class or at home. Depending on the timeframe you may want to give them a starting point and some basic information found in the case study’s learning and teaching resources.

 

Suggested timeline:

 

Team briefing:

You are a team of consultants brought in by the company who has developed Power to Food technology. Before they go to market they want to understand the ethical issues that may arise from the technology and address them if possible. They want you to look at the process as a whole and identify any ethical issues that might come up. They also want to know how easy these issues might be to address and want you to suggest potential ways to address them. You will need to provide the company with a briefing on your findings.

 

Tools:

It’s useful to give teams some frameworks through which they can do an analysis of the production process. One of those is to discuss who is harmed by the process at each stage. This is harm in the widest possible sense: physical, environment, political, reputational etc. What or who could be impacted and how? Another framework is the values of the people or entities involved in the process: what are they trying to achieve or what do they want and are any of these in conflict? Topics such as sustainability and accessibility also have an ethical dimension, and using these as a lens can help students to look at the problem from a different viewpoint.

 

Prompts for questions:

These are questions that you can get students to answer in class or suggest that they cover in an assessment. This could also be information you give the team so that they can use it as a foundation.

 

Assessment:

This group activity lends itself to a few different assessment formats, depending on what fits with your programme and timeframe. The two key things to assess are whether students can understand and identify ethical issues across the whole Power to Food production process and whether they can discuss ways to address these issues and the complexities that can be involved in addressing these issues. These two things can be assessed separately; for example through a written report where teams discuss the potential issues and a presentation where they talk about how they might address these issues. Or one assessment can cover both topics. This can be a written report, a live or recorded presentation, a video, podcast or a poster. Teams being able to see other teams’ contributions is both a good way of getting them to discuss different viewpoints and makes for a fun session. You can get teams to present their final work or a draft to each other.

Depending on the timeframe, you may also want to build in some skills assessment too. The AAC&U’s VALUE rubrics are a great starting point for assessing skills and IPAC is a good tool for assessing teamwork via peer assessment.

 

Marking Criteria:

Good Average Poor
Understanding and identification of ethics issues across the whole Power to Food production process Has identified and understood context specific ethical issues across the production process. May have shown some understanding of how issues may impact on each other. Has identified and understood broad/general ethical issues around production processes but hasn’t linked much to the specific context of the case study. Some stages may be more detailed than others. Has not identified many or any ethical issues and seems to have not understood what we’re looking for.
Discussing ways to address these issues and the complexities that can be involved Has identified context specific ways to address the ethical issues raised and has understood the potential complexities of addressing those ethical issues. Has identified broad/general ways to address the ethical issues raised and made some reference to differing levels of complexity in addressing ethical issues. Has not identified many or any ways to address the ethical issues raised and seems to have not understood what we’re looking for.
Communication Very clear, engaging and easy to understand communication of the ethical issues involved and ways to address them. Right language level for the audience. Generally understandable but not clear in places or uses the wrong level of language for the audience (assumes too much or not enough prior knowledge). Difficult to understand the point being made either due to language used or disconnection to the point of the assessment or topic.

Learning and teaching notes:

This case requires an engineer with strong convictions about sustainable energy to make a decision about whether or not to take a lucrative contract from the oil industry. Situated in Algeria, 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 financial wellbeing 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 the environment and its connection to human life and services.

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:

You are an electrical engineer who had a three-year contract with a charity in Algeria to install solar systems on remote houses and farms that were not yet connected to the grid. The charity’s project came to an end and you have set up your own company to continue the work. It has been difficult raising money from investors to fund the project and the fledgling business is in debt. It is doubtful that your company will survive for much longer without a high-profit project.

During your time in Algeria, you have made many local and regional contacts in the energy industry. Through one of these contacts, you learn of an energy company operating a large oil field in the region that is looking to convert to solar energy to power its injection pumping, monitoring, and control systems. In doing so, the oil field will eliminate its dependency on coal-fired electricity, increasing production while boosting the company’s environmental credentials. It also hopes to make use of a governmental tax credit for businesses that make such solar conversions.

 

Optional STOP for questions and activities:

1. Discussion: What is your initial reaction to using solar energy for oil and gas production? What might your initial reaction reveal to you about your own perspectives and values?

2. Discussion and activity: List the potential benefits and risks to implementing this technology. Are these benefits and risks the same no matter which country they are implemented in?

3. Activity: Research the trend for using solar energy in oil and gas production. Which companies are promoting it and which countries are using this technology?

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

 

Dilemma – Part one:

The following week you receive a phone call in your home office. It is a representative of the energy company named Sami. He asks you to bid for the solar installation contract for the oilfield. At first you are reluctant, it doesn’t seem right to use solar power to extract fuel that will contribute to the ongoing climate emergency. You explain your hesitation, saying “I got into the solar business because I believe we have a responsibility to future generations to develop sustainable energy.” Sami laughs and says “While you’re busy helping people who don’t exist yet, I’m trying to provide energy to the people who need it now. Surely we have a responsibility to them too?”

Sami then quotes a figure that the company is willing to pay you for the project work. You are taken aback at how large it is – the profit made on this contract would be enough to pay off your debts and give your business financial security moving forward. Still, you hesitate, telling Sami you need some time to think it over. He agrees and persuades you to attend dinner with him and his family later that week.

 

Optional STOP for questions and activities:

1. Discussion: Have you done anything wrong by accepting Sami’s dinner invitation?

2. Discussion: Environmental ethics deals with assumptions that are often unstated, such as the obligation to future generations. Like Sami, some people find that our obligation is greater to people who exist at this moment, not 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?

3. 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].

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

5. Activity: Undertake technical calculations in the areas of chemical and / or electrical engineering related to carbon offset and solar installations.

 

Dilemma – Part two:

When you arrive at Sami’s house for dinner you are surprised to find you aren’t the only guest. Leila, a finance manager at the oil company is also present. During the meal, she suggests they are considering investing in your business. “After all,” she points out, “many of our employees and their families could really use solar at their homes. We have even decided to subsidise the installation as a benefit to them.”

You are impressed by the oil company’s commitment to their workers and this would also guarantee you an income stream for 3-5 years. Of course, to guarantee the investment in your company, you will have to agree to undertake the oil field installation. You comment to Leila and Sami that it feels strange to be having these formal discussions over a family meal. “This is how we do business here,” says Sami. “You become part of our family too.”

 

Optional STOP for questions and activities:

1. Discussion: Do you accept the contract to complete the installation? Do you accept the investment in your company? Why, or why not?

2. Discussion: Is this bribery? Why, or why not?

3. Activity: Role-play the conversation between Sami, Leila, and the engineer.

4. 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.

Educational level: Advanced.

Educational aim: Practise ethical reasoning. Ethical reasoning applies 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 involves an engineer navigating multiple demands on a work project. The engineer must evaluate trade-offs between social needs, technical specifications, financial limitations, environmental needs, legal requirements, and safety. Some of these factors have obvious ethical dimensions, and others are more ambiguous. The engineer must also navigate a professional scenario in which different stakeholders try to influence the resolution of the dilemma.

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:

Power-to-X (P2X) describes a number of pathways for the transformation of electricity to alternative forms. This can be utilised for storing energy for later use, in order to balance periods of excesses and deficits resulting from the use of renewable energy technologies. It can also be used in applications that do not use electricity, such as through the transformation of electricity to hydrogen or other gases for industrial use.

One area that has seen significant development in recent years is power-to-food (PtF). This pathway results in CO2 being transformed, through chemical or biological processes powered by renewable energy, into food. One such process uses electrolysis and the Calvin cycle to create hydrocarbons from CO2, water and bacteria. The end result is a microbial protein, a substance that could be used in animal feed. Ultimately, the technology could produce a meat alternative suitable for human consumption, further reducing the carbon emissions produced by intensive animal farming.

 

Optional STOP for questions and activities: 

1. Activity: Identify the potential harms and risks of this technology, both objective and subjective. For example, could the shift of food production from soil to chemical industries concentrate power in the hands of a few? What public perceptions or cultural values might impact the acceptance or uptake of the technology? 

2. Discussion: Wider context – What social, technological, economic, environmental, political, or legal factors might need to be considered in order to implement this technology?

3. Activity: Research companies that are currently developing P2X technologies. Which industries and governments are promoting P2X? How successful have early projects been? What obstacles exist in upscaling?

4. Activity: Undertake a technical activity in the area of biochemical engineering related to the storing and transforming of renewable energy.

 

Dilemma – Part one:

You are the Chief Technical Officer at a company that has developed PtF technology that can convert CO2 to edible fatty acids (or triglycerides). The potential of CO2 capture is attractive to many stakeholders, but the combination of carbon reduction tied in with food production has generated positive media interest. The company also intends to establish its PtF facility near a major carbon polluter, that will reduce transport costs. However, some nearby residents are concerned about having a new industrial facility in their area, and have raised additional concerns about creating unsafe food.

As part of the process to commercialise this technology, you have been tasked with completing an ethical assessment. This includes an analysis of the technology’s short and long-term effects in a commercial application.

 

Optional STOP for questions and activities: 

1. Discussion and Activity: Identify different aspects of the production process where ethical concerns may arise, from production to delivery to consumption. Which ethical issues do you consider to be the most challenging to address?

2. Discussion: What cultural values might impact the ethical assessment? Does trust play a role in our ethical and consumption decisions? What internal logics / business goals might steer, or influence, the acceptance of various ethical considerations?

3. Discussion: Which areas of the ethical assessment might stakeholders be most interested in, or concerned about, and why?

4. Discussion: Does the choice of location for PtF facilities influence the ethical assessment? What problems could this PtF technology solve?

5. Discussion: What competing values or motivations might come into conflict in this scenario? What codes, standards, or authoritative bodies might be relevant to this? What is the role of ethics in technology development?

6. Activity: Assemble a bibliography of relevant professional codes, standards, and authorities.

7. Activity: Research the introduction of novel foods throughout history and / or engineering innovations in food production.

8. Activity: Write up the ethical assessment of the business case, and include findings from the previous questions and research.

 

Dilemma – Part two:

You deliver your ethical assessment to your manager. Shortly afterwards you are asked to edit the report to remove or downplay some ethical issues you have raised. The company leadership is worried that potential investors in an upcoming financing round may be dissuaded from investing in the company if you do not edit these sections.

 

Optional STOP for questions and activities: 

1. Discussion: Professional and ethical responsibilities – What are the ethical implications of editing or not editing the report? What consequences could this type of editing have? Think about stakeholders such as the company, potential investors and society.

2. Discussion: Wider considerations of business ethics – How would you recognise an ethical organisation? What are its characteristics? What is the role of ethics in business?

Educational aim: To develop ethical awareness. Ethical awareness is when an individual determines that a single situation has moral implications and can be considered from an ethical point of view.

 

Learning and teaching notes:

This case involves a dilemma that most engineering students will have to face at least once in their careers: which job offer to accept. This study allows students to consider how personal values affect professional decisions. The ethical aspect of this dilemma comes from weighing competing moral goods –that is, evaluating what might be the better choice between two ethically acceptable options. In addition, the case offers students an introduction to ethical principles underpinning EU environmental law, and a chance to debate ethical aspects surrounding emerging technologies. Finally, the case invites consideration of the injustices inherent in proposed solutions to climate change.

This case study addresses two AHEP 4 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 two parts.

Summary:

Olivia is a first-generation university student who grew up on a farm in rural Wales and was often frustrated by living in such a remote environment. When she received excellent A levels in maths and sciences, she took a place on a chemical engineering course in London.

Olivia became passionate about sustainability and thrived during her placements with companies that were working on innovative climate solutions. One of the most formative events for her  was COP26 in Glasgow. Here, she attended debates and negotiations that contributed to new global agreements limiting global warming to 1.5°C. Following this experience, Olivia has been looking for jobs that would allow her to work on the front line combating climate change.

 

Dilemma – Part one:

Olivia has received two job offers. One is a very well-paid position at CarGro, a small firm not far from her family farm. This company works on chemical analysis for soil carbon storage – the ability of soil’s organic matter to sequester carbon-rich compounds and therefore offset atmospheric CO2. 

The other offer is for an entry-level position at EnSol, a company developing the feasibility of stratospheric aerosol injection. This technology aims to mimic the effect that volcanic eruptions have on the atmosphere when they eject particles into the stratosphere that reflect sunlight and subsequently cool the planet. EnSol is a start-up located in Bristol that has connections with other European companies working on complementary technologies.

While considering these two offers, Olivia recalls an ethics lesson she had in an engineering design class. This lesson examined the ethical implications of projects that engineers choose to work on. The example used was of a biomedical engineer who had to decide whether to work on cancer cures or cancer prevention, and which was more ethically impactful. Olivia knows that both CarGro and EnSol have the potential to mitigate climate change, but she wonders if one might be better than the other. In addition, she has her own goals and motivations to consider: does she really want to work near her parents again, no matter how well-paid that job is?

 

Optional STOP for questions and activities: 

1. Discussion: Personal values – what personal values will Olivia have to weigh in order to decide which job offer to accept? 

2. Activity: research the climate mitigation potential of soil carbon sequestration (SCS) and stratospheric aerosol injection (SAI).

3. Discussion: Professional values – based on the research, which company is doing the work that Olivia might feel is most ethically impactful? Make an argument for both companies.

4. Discussion: Wider impact – what impact does the work of these two companies have? Consider this on local, regional, and global scales. Who benefits from their work, and who does not?

5. Discussion: Technical integration – undertake a technical activity in the areas of chemical engineering, energy and / or environmental engineering related to the climate mitigation potential of SCS and SAI.

 

Dilemma – Part two:

To help her with the decision, Olivia talks with three of her former professors. The first is Professor Carrera, whom Olivia accompanied to COP26. Professor Carrera specialises in technology policy, and tells Olivia about the precautionary principle, a core component of EU environmental law. This principle is designed to help governments make decisions when outcomes are uncertain.

The second is Professor Adams, Olivia’s favourite chemical engineering professor, who got her excited about emerging technologies in the area of climate change mitigation. Professor Adams emphasises the opportunity at EnSol provides, to be working on cutting-edge research and development – “the sort of technology that might make you rich, as well!”

Finally, Olivia speaks to Professor Liu, an expert in engineering ethics. Professor Liu’s latest book on social responsibility in engineering argues that many climate change mitigation technologies are inequitable because they unfairly benefit rich countries and have the potential to be risky and burdensome to poorer ones.

Based on these conversations, Olivia decides to ask the hiring managers at CarGro and EnSol some follow-up questions. Knowing she was about to make these phone calls, both her mother and her best friend Owen (who has already secured a job in Bristol) have messaged her with contradictory advice.  What does Olivia ask on the calls to CarGro and EnSol to help her make a decision?
