Learning and teaching notes: 

This resource outlines a project brief that requires an engineer to assess the local area to understand the scale of flooding and the local context. This will highlight how climate change affects everyday life, how water usage is changing and happening on our doorstep.

The project also requires the engineer to be considerate of the needs of a local business and showcases how climate change affects the economy and individual lives, enabling some degree of empathy and compassion to this exercise.

Depending upon the level of the students and considering the needs of modules or learning outcomes, the project could follow either or both of the following pathways: 

 

Pathway 1 – Introduction to Electronic Engineering (beginner/intermediate- Level 4) 

In this pathway, the project deliverables could be in the form of a physical artefact, together with a technical specification. 

 

Pathway 2 – Electromagnetics in Engineering (intermediate/advanced- Level 5) 

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

Overview:  

A local business premises near to a river has been suffering from severe flooding over the last 10 years. The business owner seeks to install a warning system that can provide adequate notice of a possible flood situation. 

 

Time frame & structure:
This project can be completed over 30 hours, either in a block covering 2-3 weeks (preferred) or 1 hour per week over the academic term. This project should be attempted in teams of 3-5 students. This would enable the group to develop a prototype, but the Specification (Pathway 1) and Technical Report (Pathway 2) could be individual submissions without collusion to enable individual assessment.

It is recommended that a genuine premises is found that has had the issues described above and a site visit could be made. This will not only give much needed context to the scenario but will also trigger emotional response and personal ownership to the problem. 

To prepare for activities related to sustainability, teachers may want to read, or assign students to pre-read the following article:
‘Mean or Green: Which values can promote stable pro-environmental behaviour?’ 

 

Context and Stakeholders: 

Flooding in the local town has become more prevalent over recent years, impacting homes and businesses. A local coffee shop priding itself on its ethical credentials is located adjacent to the river and is one of the businesses that has suffered from severe flooding over the last 10 years, causing thousands of pounds worth of spoilt stock and loss of revenue. The local council’s flood warning system is far from adequate to protect individuals on a site-by-site basis. So the shop is looking for an individual warning system, giving the manager and staff adequate notice of a possible flood situation. This will enable stock to be moved in good time to a safer drier location. The shop manager is very conscious of wanting to implement a sustainable design that uses sustainable materials and renewable energy, to promote the values of the shop. It is becoming clear that such a solution would also benefit other businesses that experience flooding and a wider solution should also be considered. 

 

Pathway 1 

This project requires assessment of the local area and ideally a visit to the retailer to understand their needs and consider options for water level monitoring. You are required to consider environmental and sustainable factors when presenting a solution.

After a visit to the premises:  

  1. Discussion: What is your initial reaction to the effects of the flooding​ and 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 causes of the flooding​ and​ does it surprise you? What might your initial reaction reveal to you about your own perspectives and values?​
  3. ​​Discussion and activity: List the potential issues and risks to installing a device in or near to the river bank. ​
  4. ​​Activity: Research water level monitoring. What are the main technical and logistical issues with this technology in this scenario?​
  5. Activity: Both cost-benefit and sustainable 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.​​     ​​
  6. Reflection: ​Obligations to future generations: Do we have a responsibility to provide a safe and healthy environment for humans that don’t yet exist, or for an ecosystem that will eventually change?​ 

 

​​Design Process​​​:

To satisfy the learning outcomes identified above the following activities are suggested.​ 

​ 

​​​Assessment activity 1 – Physical artefact​:​ 

Design, build and test a prototype flood warning device, monitoring various water levels and controlling an output or outputs in an alarm condition to meet the following as a minimum:
 

a) The device will require the use of an analogue sensor that will directly or indirectly output an electrical signal proportional to the water level. 

b) It will integrate to appropriate Operational Amplifier circuitry. 

c) The circuitry will control an output device or devices. 

d) The power consumption of the complete circuit will be assessed to allow an appropriate renewable energy supply to be specified (but not necessarily be part of the build). 

 

​​​Assessment activity 2 – ​Technical specification:​ 

The written specification and accompanying drawings shall enable a solution to be manufactured based on the study, evaluation and affirmation of the product requirements. 

The evaluation of the product requirements and consequent component selection will reference the use of design tools and problem-solving techniques. In compiling the specification the component selection and integration will highlight the underlying engineering principles that have been followed. The specification shall be no more than 1000 words (plus illustrations and references). 

 

Pathway 2

This project requires assessment of the local area and ideally a visit to the retailer to understand their needs and consider options for water level monitoring.

You are required to consider environmental and sustainable factors when presenting a solution. 

After a visit to the premises:  

  1. Discussion: What is your initial reaction to the effects of the flooding and 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 causes of the flooding​ and​ does it surprise you? What might your initial reaction reveal to you about your own perspectives and values?​
  3. Discussion and activity: List the potential issues and risks to installing a device in or near to the river bank. ​
  4. Activity: Both cost-benefit and sustainable 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.​​     ​​ 

 

Wireless communication of information electronically is now commonplace. It’s important ​for the learners ​to understand the differences between the various types both technically and commercially to enable the most appropriate form of communication to be chosen.

Pathway 1 above explains the need for a flood warning device to monitor water levels of a river. In Pathway 2, this part of the challenge (which could be achieved in isolation) is to communicate this information from the river to an office location within the town. 

 

Design Process: 

Design a communications system that will transmit data, equivalent to the height of the river in metres. The maximum frequency and distance over which the data can be transmitted should be explored and defined, but as a minimum this data should be sent every 20 seconds over a distance of 500m. 

 

​Assessment activity – Technical report: ​​     ​ 

A set of user requirements and two possible technical solutions shall be presented in the form of a Technical Report: 

The report shall be no more than 3000 words (plus illustrations and references)

Who is this article for? This article is for educators working at all levels of higher education who wish to integrate Sustainability into their robotics engineering and design curriculum or module design. It is also for students and professionals who want to seek practical guidance on how to integrate Sustainability considerations into their robotics engineering. 

 

Premise:  

There is an urgent global need to address the social and economic challenges relating to our world and the environment (Raper et al., 2022). The United Nations Sustainable Development Goals (SDGs) provide a framework for individuals, policy-makers and industries to work to address some of these challenges (Gutierrez-Bucheli et al., 2022). These 17 goals encompass areas such as clean energy, responsible consumption, climate action, and social equity. Engineers play a pivotal role in achieving these goals by developing innovative solutions that promote sustainability and they can use these goals to work to address broader sustainability objectives. 

Part of the strategy to ensure that engineers incorporate sustainability into their solution development is to ensure that engineering students are educated on these topics and taught how to incorporate considerations at all stages in the engineering process (Eidenskog et al., 2022). For instance, students need not only to have a broad awareness of topics such as the SDGs, but they also need lessons on how to ensure their engineering incorporates sustainable practice. Despite the increased effort that has been demonstrated in engineering generally, there are some challenges when the sustainability paradigm needs to be integrated into robotics study programs or modules (Leifler and Dahlin, 2020). This article details one approach to incorporate considerations of the SDGs at all stages of new robot creation: including considerations prior to design, during creation and manufacturing and post-deployment. 

 

1. During research and problem definition:

Sustainability considerations should start from the beginning of the engineering cycle for robotic systems. During this phase it is important to consider what the problem statement is for the new system, and whether the proposed solution satisfies this in a sustainable way, using Key Performance Indicators (KPIs) linked to the SDGs (United Nations, 2018), such as carbon emissions, energy efficiency and social equity (Hristov and Chirico, 2019). For instance, will the energy expended to create the robot solution be offset by the robot once it is in use? Are there long-term consequences of using a robot as a solution? It is important to begin engagement with stakeholders, such as end-users, local communities, and subject matter experts to gain insight into these types of questions and any initial concerns. Educators can provide students with opportunities to engage in the research and development of robotics technology that can solve locally relevant problems and benefit the local community. These types of research projects allow students to gain valuable research experience and explore robotics innovations through solving problems that are relatable to the students. There are some successful examples across the globe as discussed in Dias et al., 2005. 

 

2. At design and conceptualisation:

Once it is decided that a robot works as an appropriate solution, Sustainability should be integrated into the robot system’s concept and design. Considerations can include incorporating eco-design principles that prioritise resource efficiency, waste reduction, and using low-impact materials. The design should use materials with relatively low environmental footprints, assessing their complete life cycles, including extraction, production, transportation, and disposal. Powered systems should prioritise energy-efficient designs and technologies to reduce operational energy consumption, fostering sustainability from the outset. 

 

3. During creation and manufacturing:

The robotic system should be manufactured to prioritise methods that minimise, mitigate or offset waste, energy consumption, and emissions. Lean manufacturing practices can be used to optimise resource utilisation where possible. Engineers should be aware of the importance of considering sustainability in supply chain management to select suppliers with consideration of their sustainability practices, including ethical labour standards and environmentally responsible sourcing. Robotic systems should be designed in a way that is easy to assemble and disassemble, thus enabling robots to be easily recycled, or repurposed at the end of their life cycle, promoting circularity and resource conservation. 

 

4. Deployment:

Many robotic systems are designed to run constantly day and night in working environments such as manufacturing plants and warehouses. Thus energy-efficient operation is crucial to ensure users operate the product or system efficiently, utilising energy-saving features to reduce operational impacts. Guidance and resources should be provided to users to encourage sustainable practices during the operational phase. System designers should also implement systems for continuous monitoring of performance and data collection to identify opportunities for improvement throughout the operational life. 

 

5. Disposal:

Industrial robots have an average service life of 6-7 years. It is important to consider their end-of-life and plan for responsible disposal or recycling of product components. Designs should be prioritised that facilitate disassembly and recycling (Karastoyanov and Karastanev, 2018). Engineers should identify and safely manage hazardous materials to comply with regulations and prevent environmental harm. Designers can also explore options for product take-back and recycling as part of a circular economy strategy. There are various ways of achieving that. Designers can adopt modular design methodologies to enable upgrades and repairs, extending their useful life. Robot system manufacturers should be encouraged to develop strategies for refurbishing and reselling products, promoting reuse over disposal. 

 

Conclusion: 

Sustainability is not just an option but an imperative within the realm of engineering. Engineers must find solutions that not only meet technical and economic requirements but also align with environmental, social, and economic sustainability goals. As well as educating students on the broader topics and issues relating to Sustainability, there is a need for teaching considerations at different stages in the robot development lifecycle. Understanding the multifaceted connections between sustainability and engineering disciplines, as well as their impact across various stages of the engineering process, is essential for engineers to meet the challenges of the 21st century responsibly.

Premise:  

Global challenges that call for environmental, sustainable and innovative solutions have consistently pushed us to be open to the changes and challenges within engineering education (Graham, 2012; Graham, 2018; Crawley et al., 2014; Lawlor, 2013; The Royal Academy of Engineering, 2007). Despite the prevalence of the UN Sustainable Development Goals (SDGs) since 2015, several reports and studies (Mulder et al., 2012; Buckler and Creech, 2014; Lazzarini et al., 2018; Morrissey, 2013; Neubauer et al., 2017; Wals, 2014; Miñano Rubio et al. 2019) have noted that the incorporation of sustainability within universities finds the greatest barrier in the field of teaching, with curricula often failing to address key environmental and ethical issues. This situation reflects the need for educators to develop a toolkit of resource materials that can serve as a reference guide for the effective and systematic integration of sustainability into university engineering curricula (Thürer et al., 2018).  

 

Basic principles for embedding sustainability and ethics:  

The principles for integrating sustainability into mathematical problems and exercises within the engineering curricula share strong parallels to the embedding of ethical components, as documented within several guidance articles from the EPC’s Engineering Ethics Toolkit. Some of these include:  

 

 

 

 

 

Examples of mathematical problems with embedded sustainability:  

The following three example problems from Chiodo and Muller, 2023 with minor adaptations (as permitted under the Creative Commons License CC BY-SA 4.0), illustrate ways in which sustainability aspects can be integrated within traditional technical exercise questions found in engineering mathematics courses:  

Partial solution comments have been included here for brevity, please refer to Chiodo and Muller, 2023 for full solution details.  

 

Problem 1: Pipeline construction 

Topic: Optimisation. 

SDG mapping: SDG 7 (Affordable and Clean Energy), SDG 9 (Industry, Innovation and Infrastructure), SDG 14 (Life Below Water), SDG 15 (Life on Land). 

An oil company wants to build a pipeline connecting an oil platform to a refinery (on land). The coastline is straight. The oil platform is at a distance of 13km from the coast. The refinery is on the coastline, a distance 10km from the point on the coast closest to the platform. Building the pipeline will lead to a cost of £90,000 per km at sea and £60,000 per km on land.  

 

Calculate the optimal length for building the pipeline. What are the factors that need to be considered when providing a response to this question?  

 

Solution comments: The cost-minimising path is given by Snell’s law and is an exercise in trigonometry and calculus. But who said we were optimising over cost? This is an assumption often engrained into engineers while they are students, but it need not always be the right way to optimise. How many decisions made by government agencies (often based on advice offered by mathematical consultants) use economics as the sole criterion for optimisation?  

Economic actions almost always have externalities, such as possible damage to the environment (the pipe may go through a coral reef or protected habitat) or to existing infrastructure (it may go through a school or a site of archaeological significance). How could we mathematically model the environmental and human impact of laying this pipe? There are numerous factors to consider and students, much like policymakers would, should take a holistic view of these effects and at least be aware of, and question the implications of basing decisions solely on economic factors. 

 

Problem 2: Environmental disasters 

Topic: Differential equations. 

SDG mapping: SDG 6 (Clean Water and Sanitation), SDG 12 (Responsible Consumption and Production). 

A chemical accident took place near a small village in Peru. The region’s local water reservoir has a volume V. The inflow and outflow of the reservoir is given by the flow rate r. Let x(t) be the amount of mercury in the reservoir at time t. Assume that the reservoir was clean at the beginning i.e., x(0) = 0. Let C(t) be the concentration of mercury flowing into the reservoir.  

 

a. Set up and solve a differential equation describing the concentration of the reservoir.  

b. How can you use your solution to model repeated pollution (e.g., criminals dumping mercury near the reservoir every weekend)?  

c. What are some relevant questions you can ask about the concentration of mercury in the reservoir?  

d. Suppose that the polluter is caught and after some cleaning, the incoming water is clean. How can you use your model to analyse when the water in the reservoir will be safe again? How sure are you of your answer and how much does it matter?  

 

Solution comments: This question is designed to show students that very simple mathematics can be used to model local environmental disasters, which can often be an example of how it may be used unsustainably. It teaches students to find good questions instead of merely answering someone else’s questions. 

For part c), possible questions for students to consider can include:  

For part d) for the sub question “How sure are you?”, students will need to explore what the ‘known’ unknowns are e.g., errors in the measurement apparatus, non-uniform mixing, samples taken in a very clean/dirty part of the stream or reservoir. They may also need to consider any ‘unknown’ unknowns e.g., other sources of pollutants, samples being tampered with accidentally or deliberately, etc. 

For part d) for the sub question “How much does it matter?”, students should identify that we are dealing with poison in drinking water, so it matters immensely! They should understand that this is an estimate, which helps forecast when the water might be safe to drink (the only way to actually know is to thoroughly test it). This question helps students to realise that the mathematics is simply one part of a much bigger solution and should not be relied upon as a definitive answer to a question as serious as the safety of drinking water.  

 

Problem 3: Simpson’s paradox 

Topic: Probability. 

SDG Mapping: SDG 5 (Gender Equality), SDG 10 (Reduced Inequalities). 

In a particular admissions cycle, a mathematics department observes a higher success rate for male applicants than for female applicants. To investigate whether this is the same across he two sub-departments of Pure Mathematics and Applied Mathematics, the following year the department asks each applicant to give their preference for pure or applied mathematics (they are not allowed to be ambivalent) and records the resulting statistics as shown in Figure 4 below:  

                                                                            Total

Applications Successful
Female 300 30
Male 1000 210
              Prefer applied

Applications Successful
Female 270 18
Male 350 15
                     Prefer pure

Applications Successful
Female 30 12
Male 650 195

 

 

          Figure 4: Admission statistics for male and female applications to study mathematics  

 

 

a. Compare the success rates for male and female applicants that prefer applied mathematics, prefer pure mathematics and their success rates overall.  

b. What do you notice? Why is this possible? This is known as Simpson’s Paradox.  

c. If possible, find the admission statistics by gender and mathematics preference (pure/applied) from your university’s mathematics department and see if the same phenomenon occurs.  

 

Solution comments: The purpose of this question is to demonstrate Simpson’s paradox in which a trend appears in several different groups of data but disappears or reverses when these groups are combined. It also attempts to highlight the immense gender disparity in many mathematics departments around the world.  

For part b) it is evident from the calculations in part a) that females with a given preference (pure/applied mathematics) have a higher success rate than males with the same preference, but lower overall. This is Simpson’s Paradox. The heuristic reason for why this is possible is that the largest male cohort (those that prefer pure) has a much higher acceptance rate than the largest female cohort (those that prefer applied). So, the overall acceptance of men is dominated by those who prefer pure, while the overall acceptance of women is dominated by those who prefer applied. This is a great lesson in why it is usually a terrible idea to take “averages of averages”. 

The main purpose of part c) is not so much for students to redo the calculation (it is not a given that Simpson’s Paradox will always arise here), but rather to illustrate the immense gender disparity in many mathematics departments around the world.  

  

Conclusion:  

The aim of this article is to provide academics and educators in higher education with an insight into how sustainability concepts may be integrated into technical, mathematical problems prevalent throughout engineering curricula. This should hopefully motivate lecturers to design their own versions of similar exercises to embed within their own courses and help build on ongoing calls to enhance the restructuring of our university programmes to better prepare future engineers to tackle global sustainability challenges by drawing not only on their technical and scientific knowledge, but also on their creativity, ethical, professional and leadership skills.

Who is this article for? This article should be read by educators at all levels in higher education who wish to consider how to navigate tradeoffs between economic and environmental sustainability as they apply to engineering. Engaging with this topic will also help to prepare students with the soft skill sets that employers are looking for. 

 

Premise:  

In the face of the ever-growing need for economic progress and the escalating environmental crises, the engineering profession finds itself at a crossroads. Striking a delicate balance between economic growth and environmental sustainability is no longer an option but an imperative. This article delves into the pivotal role of engineering educators in shaping the mindset of future engineers, offering an expanded educational framework that fosters a generation capable of harmonising economic prosperity with environmental responsibility. 

  

The uneasy truce:  

Developing nations, with burgeoning populations and aspirations for improved living standards, grapple with the paradox of rapid economic expansion at the expense of environmental degradation. This necessitates a shift in focus for engineering educators, who bear the responsibility of cultivating engineers with a foresighted perspective. Rather than demonising economic growth, the goal is to instill a nuanced understanding of its interdependence with environmental well-being. For example, in developing countries like Brazil, rapid economic expansion driven by industries such as agriculture and logging has resulted in extensive deforestation of the Amazon region. This deforestation not only leads to the loss of valuable biodiversity and ecosystem services but also contributes to climate change through the release of carbon dioxide. Similarly, in industrialised nations, the pursuit of economic growth has often led to the pollution of air, water, and soil, causing adverse health effects for both humans and wildlife. 

 

Equipping our future stewards: 

To navigate this delicate landscape, educators must move beyond traditional technical expertise, fostering a holistic approach that integrates ethical awareness, interdisciplinary collaboration, localised solutions, and a commitment to lifelong learning. 

1. Ethical awareness: One potential counterargument to the expanded educational framework may be that the focus of engineering education should remain solely on technical expertise, with the assumption that ethical considerations and interdisciplinary collaboration can be addressed later in a professional context. However, research has shown that integrating ethical awareness and interdisciplinary collaboration early in engineering education not only enhances problem-solving skills but also cultivates a sense of responsibility and long-term thinking among future engineers. 

2. Holistic thinking: Research has shown that interdisciplinary collaboration between engineering and social science disciplines can lead to more effective and sustainable solutions. For instance, a study conducted by the World Bank’s Water and Sanitation Program (WSP) found that by involving sociologists and anthropologists in the design and implementation of water infrastructure projects in rural communities, engineers were able to address cultural preferences and local knowledge, resulting in higher acceptance and long-term maintenance of the infrastructure. Similarly, a case study of a renewable energy project in Germany demonstrated how taking into account the geographic nuances of the region, such as wind patterns and solar radiation, led to more efficient and cost-effective energy solutions. Presently, Germany boasts the world’s fourth-largest installed solar capacity and ranks amongst the top wind energy producers.  

3. Localised solutions: Students must be required to consider the social, cultural, and geographic nuances of each project. This means moving away from one-size-fits-all approaches and towards an emphasis on the importance of context-specific solutions. This ensures that interventions are not only technologically sound but also culturally appropriate and responsive to local needs, fostering sustainability at both the project and community levels. 

4. Lifelong learning: Empower students with the skills to stay abreast of emerging technologies, ethical frameworks, and policy landscapes. Recognise that the landscape of sustainability is dynamic and ever evolving. Foster a culture of continuous learning and adaptability to ensure that graduates remain true stewards of a sustainable future, equipped to navigate evolving challenges throughout their careers. 

 

A compass for progress:  

By integrating these principles into engineering curricula, educators can provide students with a moral and intellectual compass—an ethical framework guiding decisions toward a future where economic progress and environmental responsibility coexist harmoniously. Achieving this paradigm shift will require collaboration, innovation, and a willingness to challenge the status quo. However, the rewards are immeasurable: a generation of engineers empowered to build a world where prosperity thrives alongside a healthy planet—a testament to the true potential of the engineering profession. 

Engineering teachers can raise a generation of engineers who can balance economic growth with environmental responsibility by embracing a broader educational framework that includes ethical awareness, cross-disciplinary collaboration, localised solutions, and a commitment to lifelong learning. Through the adoption of these principles, engineering curricula can provide students with a moral and intellectual compass, guiding them toward a future where economic progress and environmental sustainability coexist harmoniously.

Who is this article for? This article should be read by educators at all levels in higher education who are seeking an overall perspective on teaching approaches for integrating sustainability in engineering education. Engaging with this topic will also help to prepare students with the soft skill sets that employers are looking for. 

 

Premise: 

As stated in the 1987 United Nations Brundtland Report, ‘sustainability’ refers to “meeting the needs of the present without compromising the ability of future generations to meet their own needs” (GH, 1987 p.242). It is underpinned by a tripartite definition encompassing environmental, social and economic sustainability. The necessity for embracing sustainability is underscored by several pressing challenges we face as a global society, ranging from climate change to economic crises.  

Against the backdrop of these global challenges, the role of the engineering profession assumes significant importance. While the scientific principles that underpin the various engineering disciplines remain largely the same, the responsibility of the engineering profession is to leverage these principles to address current and future challenges. Consequently, education for sustainable development (ESD) becomes a vital aspect of an engineer’s training, since the profession will guide the design and implementation of innovative solutions to challenges crosscutting environmental impact, judicious use of resources and social wellbeing.   

 

Integrated course design: 

Integrating ESD in engineering education requires programme and module designers to take a deliberate approach. Drawing on initial attempts to integrate sustainability in management and business education (Rusinko, 2010), four pedagogical approaches of ESD can be identified:  

  1. piggybacking,  
  2. mainstreaming,  
  3. specialising,  
  4. connecting.  

The last two approaches are for creating new curriculum structures with a narrow discipline-specific focus and a broad transdisciplinary focus, respectively. The other two, piggybacking and mainstreaming, are approaches to embed sustainability within existing curriculum structures. Although piggybacking is the easier-to-implement approach, achieved by additional sessions or resources on sustainability being tagged onto existing course modules, mainstreaming enables a broader cross-curricular perspective that intricately intertwines sustainability with engineering principles. 

The mainstreaming approach is also an elegant fit with the accreditation requirements for sustainability; the latest edition of the Accreditation of Higher Education Programmes (AHEP) emphasises competence in evaluating ‘environmental and societal impact of solutions’ to ‘broadly-defined’ and ‘complex’ problems. In order to foster this ability, where sustainability is a guiding principle for developing engineering solutions, a holistic (re)consideration of all elements of constructive alignment (Biggs, 1996) – intended learning outcomes (ILOs), teaching and learning activities, and student assessment – is needed. To this end, the Integrated Course Design (ICD) pedagogical framework can be leveraged for a simultaneous and integrated consideration of course components for embedding sustainability.  

 

Sustainability learning outcomes: 

Bloom’s taxonomy (also see here), which conventionally guides formulation of ILOs, can be extended to incorporate sustainability-based learning outcomes. The action verb in the AHEP guidance for the learning outcome on sustainability is ‘evaluate’, signifying a high cognitive learning level. ILOs framed at this level call for application of foundational knowledge through practical, critical and creative thinking. Although the cognitive domain of learning is the main component of engineering education, sustainability competence is greater than just a cognitive ability. For more information, see the Reimagined Degree Map.   

ESD is a lifelong learning process and as stated by UNESCO, it ‘enhances the cognitive, socio-emotional and behavioural dimensions of learning’. This integration of cognitive learning outcomes with affective aspects, referred to as ‘significant learning’ in the ICD terminology, is of utmost importance to develop engineers who can engage in sustainable and inclusive innovation. Furthermore, mapping programme and module ILOs to the UN Sustainable Development Goals (SDGs) is another way to integrate sustainability in engineering with connections between technical engineering competence and global sustainability challenges becoming more explicit to students and educators. Similarly, the ILOs can be mapped against UNESCO’s sustainability competencies to identify scope for improvement in current programmes. See the Engineering for One Planet Framework for more information and guidance on mapping ILOs to sustainability outcomes and competencies. 

 

Teaching and learning activities: 

Activities that engage students in ‘active learning’ are best placed to foster sustainability skills. Additional lecture material on sustainability and its relevance to engineering (piggybacking approach) will have limited impact. This needs to be supplemented with experiential learning and opportunities for reflection. To this end, design and research projects are very effective tools, provided the problem definition is formulated with a sustainability focus (Glassey and Haile, 2012). Examples include carbon capture plants (chemical engineering), green buildings (civil engineering) and renewable energy systems (mechanical and electrical engineering).  

Project-based learning enables multiple opportunities for feedback and self-reflection, which can be exploited to reinforce sustainability competencies. However, with project work often appearing more prominently only in the latter half of degree programmes, it is important to consider other avenues. Within individual modules, technical content can be contextualised to the background of global sustainability challenges. Relevant case studies can be used in a flipped class environment for a more student-led teaching approach, where topical issues such as microplastic pollution and critical minerals for energy transition can be taken up for discussion (Ravi, 2023). Likewise, problem sheets or simulation exercises can be designed to couple technical skills with sustainability.    

  

Student assessment: 

With sustainability being embedded in ILOs and educational activities, the assessment of sustainability competence would also need to take a similar holistic approach. In other words, assessment tasks should interlace engineering concepts with sustainability principles. These assessments are more likely to be of the open-ended type, which is also the case with design projects mentioned earlier. Such engineering design problems often come with conflicting constraints (technical, business, societal, economic and environmental) that need careful deliberation and are not suited for conventional closed-book time-limited examinations.  

More appropriate tools to assess sustainability, include scaled self-assessment, reflective writing and focus groups or interviews (Redman et al., 2021). In a broader pedagogical sense, these are referred to as authentic assessment strategies. Given the nexus between sustainability and ethics, inspiration can also be drawn from how ethics is being assessed in engineering education. Finally, pedagogical models such as the systems thinking hierarchical model (Orgill et al., 2019), can be used to inform the design of assessment rubrics when evaluating sustainability skills.

Professional situations: EDI; Communication; Conflicts with leadership/management; Quality of work; Personal/professional reputation.

Educational level: Intermediate.

Educational aim: Practising Ethical Analysis: engaging in a process by which ethical issues are defined, affected parties and consequences are identified, so that relevant moral principles can be applied to a situation in order to determine possible courses of action.

 

Learning and teaching notes:

This case involves an early-career consultant engineer working in the area of sustainable construction. She must negotiate between the values that she, her employer, and her client hold in order to balance sustainability goals and profit. The summary involves analysis of personal values and technical issues, and parts one and two bring in further complications that require the engineer to decide how much to compromise her own values.

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 two parts. If desired, a teacher can use the Summary and Part one in isolation, but Part two develops and complicates the concepts presented in the Summary and 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.

Summary:

Originally from rural Pakistan, Anika is a construction engineer who has recently finished her postgraduate degree, having been awarded a fully funded scholarship. During her studies, Anika was introduced to innovative projects using mass timber and off-site methods of construction. After completing her studies, she was inspired to start her own consultancy practice in the UK, aiming to promote the use of sustainable materials within the construction industry.

James is the director of a well-established, family-owned architectural firm, originally started by his great-grandfather who was also a prominent societal figure. In the last year, James and his colleagues have sought to develop a sustainability policy for the firm. A key feature of this new policy is a commitment to adopt innovative, sustainable construction solutions wherever possible. James has been contacted by an important client who wants to commission his firm to work on a new residential development.

James first met Anika at university when they were both studying for the same postgraduate degree. Having a high regard for Anika’s capability and professionalism, James contacts Anika to propose working together to develop a proposal for the new residential development.

James hopes that Anika’s involvement will persuade the client to select construction solutions that are aligned with the new sustainability policy adopted by his firm. However, the important client has a reputation for prioritising profit over quality, and openly admits to being sceptical about environmental issues.

Anika schedules a meeting with the client to introduce herself and discuss some initial ideas for the project.

 

Optional STOP for questions and activities:

1. Discussion: Personal values – What are the different personal values for Anika, James, and the client? How might they conflict with each other?

2. Activity: Professional communication – Elevator pitch activity part 1 – Working in groups of 2-3 and looking at the three different stakeholders’ personal values, each group will create a persuasive pitch of 1 minute used by Anika to convince the client to focus on sustainability.

3. Activity: Technical Analysis – Assemble a bibliography of relevant projects using mass timber and off-site methods of construction, and identify the weaknesses and strengths of these projects in terms of sustainability and long- and short-term costs and benefits.

4. Activity:  Professional communication – Elevator pitch activity part 2 – After conducting your technical analysis, work in groups of 2-3 to revise your elevator pitch and role play the meeting with the client. How should Anika approach the meeting?

 

Dilemma – Part one:

After the first meeting, the client expresses major concerns about Anika’s vision. Firstly, the client states that the initial costings are too high, resulting in a reduced profit margin for the development. Secondly, the client has serious misgivings about the use of mass timber, citing concerns about fire safety and the durability of the material.

Anika is disheartened at the client’s stance, and is also frustrated by James, who has a tendency to contradict and interrupt her during meetings with the client. Anika is also aware that James has met with the client on various occasions without extending the invitation to her, most notably a drinks and dinner reception at a luxury hotel. However, despite her misgivings, Anika knows that being involved in this project will secure the future of her own fledgling consulting company in the short term – and therefore, reluctantly, suspects she will have to make compromises.

 

Optional STOP for questions and activities:

1. Discussion: Leadership and Communication – Which global responsibilities does Anika face as an engineer? Are those personal or professional responsibilities, or both? How should Anika balance her ethical duties, both personal and professional, and at the same time reach a decision with the client?

2. Activity: Research – Assemble a bibliography of relevant projects where mass timber has been used. How might you design a study to evaluate its structural and environmental credentials? What additional research needs to be conducted in order for more acceptance of this construction method?

3. Activity: Wider impact – Looking at Anika’s idea of using mass timber and off-site methods of construction, students will work in groups of 3-4 to identify the values categories of the following capital models: Natural, Social, Human, Manufactured and Financial.

4. Activity: Equality, Diversity, and Inclusion – Map and analyse qualities and abilities in connection with women and how these can have a positive and negative impact in the construction industry.

5. Discussion: Leadership and Communication – Which are the competitive advantages of women leading sustainable businesses and organisations? Which coping strategy should Anika use for her working relationship with James?

 

Dilemma – Part two:

Despite some initial misgivings, the client has commissioned James and Anika to work on the new residential development. Anika has begun researching where to locally source mass timber products. During her research, Anika discovers a new off-site construction company that uses homegrown mass timber. Anika is excited by this discovery as most timber products are imported from abroad, meaning the environmental impact can be mitigated.

 

Optional STOP for questions and activities:

1. Activity: Environmental footprint – Research the Environmental Product Declaration of different construction materials and whole life carbon assessment.

2. Discussion: Is transportation the only benefit of using local resources? Which other values (Natural, Social, Human, Manufactured and Financial) can be maximised with the use of local resources? How should these values be weighted?

3. Discussion: Professional responsibility – How important is Corporate Social Responsibility (CSR) in Construction? How could the use of local biogenic materials and off-site methods of construction be incorporated into a strategic CSR business plan?

Learning and teaching notes:

At COP26, H.E. President Muhammadu Buhari announced Nigeria’s commitment to carbon neutrality by 2050. This case involves an engineer who is one of the stakeholders invited by the president of Nigeria to implement an Energy Transition Plan (ETP). It requires the engineer, who is a professional and well experienced in renewable energy and energy transition, to deliver a comprehensive decarbonisation roadmap that will ensure net zero emissions.

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.

Dilemma – Part one:

You are an electrical engineer working as a technical consultant in an international organisation aiming to  transform the global energy system to secure a clean, prosperous, zero-carbon future for all. The organisation is one of the stakeholders invited by the federal government of Nigeria to implement the country’s new Energy Transition Plan (ETP) and you are given the task of creating a comprehensive decarbonisation roadmap and presenting it at the stakeholder meeting.

 

Optional STOP for questions and activities:

1. Discussion: In what ways could an electrical engineer bring needed expertise to the ETP? Why are engineers essential to ensuring a zero-carbon future? Should engineers be involved in policy planning? Why or why not?

2. Activity: Wider context research: Nigeria is currently an oil-producing country. What might policy makers need to consider about this reality when implementing an ETP? How strongly should you advocate for a reduction of the use of fossil fuels in the energy mix?

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

4. Activity: Research and outline countries that have attained a zero emission target. What are their energy distribution mixes? Based on this information, what approach should Nigeria take and why?

5. Activity: What will be your presentation strategy at the stakeholder meeting? What will you advocate for and why? What ethical justifications can you make for the plan you propose?

 

Dilemma – Part two:

At the stakeholder meeting, you were given the opportunity to present your decarbonisation roadmap and afterwards faced serious opposition by the chief lobbyist of the Fossil Fuel and Mining Association, Mr. Abiola. Mr. Abiola is of the opinion that because Nigeria contributes less than 1% to the global emissions, it should not be held accountable for climate change, and therefore no country-wide climate policy is necessary. Furthermore, he fears the domestic market for coal that is used to produce electricity as well as the global market for fossil fuels will shrink because of the new policy. He also argues that a shift away from coal and fossil fuels could result in challenges to the security of supply, since renewables are by definition unreliable and volatile. Other stakeholders, such as activists and environmental experts, also voiced different concerns and opinions. They argue that time has already run out, and no country can delay decarbonisation plans no matter how small their impact on the global total. This conflict has resulted in disagreements in the negotiation.

 

Optional STOP for questions and activities:

1. Debate: Do different countries have different ethical responsibilities when it comes to decarbonisation? Why or why not? If so, for what reasons?

2. Discussion: How should countries weigh the short-term versus long-term benefits and burdens of the energy transition? What role do governments and corporations play in managing those? What role should citizens play?

3. Discussion: How will you prepare for and handle opposing questions to your roadmap plan? 

4. Activity: Create a participatory stakeholder engagement plan embedded in the overall decarbonisation strategy.

5. Activity: How will you utilise the different renewable energy mix to provide 100% access to electricity and ensure security of supply as an electrical engineer?

Learning and teaching notes:  

This case study involves a young engineering student on an industrial placement year at a firm that manufactures cosmetics. The student has been working hard to impress the company as they are aware that this may lead to them being offered a job upon graduation. They are involved in a big project that focuses on alternative, more environmentally friendly cosmetic chemistries. When they notice a potential problem with the new formulation, they must balance their commitment towards environmental sustainability with their desire to work for the company upon graduation.  

This dilemma can be addressed from a micro-ethics point of view by analysing personal ethics, intrinsic motivations and moral values. It can also be analysed from a macro-ethics point of view, by considering corporate responsibility and intergenerational justice. The dilemma can also be framed to emphasise global responsibility and environmental justice whereby the engineers consider the implications of their decisions on global communities and future generations.  

This case study addresses two of the themes from the Accreditation of Higher 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).

Microplastics are solid plastic particles composed of mixtures of polymers and functional additives; they also contain residual impurities. Microplastics generally fall into two groups: those that are unintentionally formed as a result of the wear and tear of larger pieces of plastic, and those that are deliberately manufactured and added to products for specific purposes (primary microplastics). Microplastics are intentionally added to a range of products including cosmetics, in which they act as abrasives and can control the thickness, appearance, and stability of a product.  

Legislation pertaining to the use of microplastics varies worldwide and several loopholes in the regulations have been identified. Whilst many multinational companies have fought the introduction of such regulations, other stakeholders have urged for the use of the precautionary principle, suggesting that all synthetic polymers should be regulated in order to prevent significant damage to both the environment and human health. 

Recently, several changes to the regulation of microplastics have been proposed within Europe. One that affects the cosmetics industry particularly concerns the intentional addition of microplastics to cosmetics. Manufacturers, especially those who export their products, have therefore been working to change their products. 

 

Optional STOP for questions and activities:  

1. Discussion: Professional values – What ethical principles and codes of conduct are applicable to the use of microplastics? Should these change or be applied differently when the microplastics are used in products that may be swallowed or absorbed through the eyes or skin?

2. Activity: Research some of the current legislation in place surrounding the use of microplastics. Focus on the strengths and limitations of such legislation.  

3. Activity: Technical integration – Research the potential health and environmental concerns surrounding microplastics. Investigate alternative materials and/or technological solutions to the microplastic ‘problem’.  

4. Discussion: Familiarise yourself with the precautionary principle. What are the advantages and disadvantages of applying the precautionary principle in this situation?  

 

Dilemma – Part two: 

Alex is a young engineering student on an industrial placement year at a firm that manufactures cosmetics. The company has been commended for their sustainable approach and Alex is really excited to have been offered a role that involves work aligned with their passion. They are working hard to impress the company as they are aware that this may lead to them being offered a job upon graduation.  

Alex is involved in a big project that focuses on alternative, more environmentally friendly cosmetic chemistries. Whilst working in the formulation laboratory, they notice that some of the old filler material has been left near the preparation area. The container is not securely fastened, and residue is visible in the surrounding area. The filler contains microplastics and has recently been taken out of products. However, it is still in stock so that it could be used for comparative testing, during which the performance of traditional, microplastic containing formulations are compared to newly developed formulations. It is unusual for the old filler material to be used outside of the testing laboratory and Alex becomes concerned about the possibility that the microplastics have been added to a batch of the new product that had been made the previous day. They raise the issue to their supervisor, asking whether the new batch should be quarantined.  

“We wouldn’t ever hold such a large, lucrative order based on an uncertainty like that,” the supervisor replies, claiming that even if there was contamination it wasn’t intentional and would therefore not be covered by the legislation. “Besides, most of our products go to countries where the rules are different.” 

Alex mentions the health and environmental issues associated with microplastics, and the reputation the company has with customers for being ethical and sustainable. They suggest that they bring the issue up with the waste and environmental team who have expertise in this area.  

Their supervisor replies: “Everyone knows that the real issue is the microplastics that are formed from disintegration of larger plastics. Bringing up this issue is only going to raise questions about your competence.”  

 

Optional STOP for questions and activities: 

1. Discussion: Personal values – What competing personal values or motivations might trigger an internal conflict for Alex? 

2. Activity: Research intergenerational justice and environmental justice. How do they relate to this case? 

3. Activity: Identify all potential stakeholders and their values, motivations, and responsibilities. 

4. Discussion: Consider both the legislation in place and the RAEng/Engineering Council Ethical Principles. What should Alex do according to each of these? Is the answer the same for both? If not, which set of guidance is more important? 

5. Discussion: How do you think the issue of microplastics should be controlled? 

6. Activity: Alex and their boss are focused on primary microplastics. Consider the lifecycle of bulk plastics and the various stakeholders involved. Who should be responsible for the microplastics generated during the disintegration of plastic products?

7. Discussion: What options for action does Alex have available to them? What are the advantages and disadvantages of each approach? What would you do if you were Alex? 

8. Activity: Technical integration related to calculations or experiments on microplastics.

Topic: Maintenance of an offshore wind farm.

Engineering disciplines: Mechanical; Energy.

Ethical issues: Sustainability; Risk.

Professional Situations: Public health and safety; Quality of work; Conflicts with leadership/management.

Educational level: Beginner.

Educational aim: Becoming Ethically Aware: determining that a single situation can be considered from a ethical point of view.

 

Learning and teaching notes:

The case is based on a genuine challenge raised by a multinational energy company that operates an offshore wind farm in the North Sea. It involves three professional engineers responsible for various aspects of the project to negotiate elements of safety, risk, environmental impact, and costs, in order to develop a maintenance plan for the wind turbine blades.

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.

This case is presented in two parts. In the first part, the perspectives and responsibilities of the three engineers are outlined so that students can determine what professional and ethical responsibilities are inherent in their roles. In the second part, a scenario is developed that puts the roles into potential conflict. Students then have the opportunity to work through a real-world brief that requires them to negotiate in order to present a solution to management. Teachers can choose to use Part one in isolation, or some or all of Part two to expand on the issues in the case. The case allows teachers the option to stop at multiple points for questions and / or activities, as desired.

Dilemma – Part one:

Offshore wind has huge benefits to the electricity industry as a renewable, low carbon resource.  The size and scale of the turbines, together with the remoteness – the wind farm referred to in this case is 200 km from shore – are a problem. However, it is a rapidly maturing industry and many of the issues around accessibility during installation have been solved. A wind farm is expected to generate for twenty years and so a system of inspection and maintenance needs to be put in place. At the same time, the environmental impact of industrial activity (including ongoing maintenance and repairs) needs to be managed in order to mitigate risks to ecosystem resources and services provided by the open sea.

In this wind farm there are one hundred turbines, each with three blades. The blades are 108 m long. Clearly, they need to be kept in good condition. However, inspecting the blades is a difficult and time consuming job.

There are three engineers that are responsible for various aspects of maintenance of the wind turbine blades. They are:

1. Blade engineer: My job is to make sure the blades are in good condition so that the wind farm operates as it was designed and generates as much power as possible. I am responsible for:

2. Health and safety engineer: My job is to make sure that the technicians who inspect and maintain the turbine blades are at minimal risk. I need to ensure compliance with:

3. Environmental engineer: My job is to ensure that the ecosystem is damaged as little as possible during turbine inspection and maintenance, and to rectify as best as possible any adverse effects that are incurred. After all, wind power is considered to be “green” energy and so wind farms should do as little damage to the environment as possible. This work helps:

 

Optional STOP for questions and activities:

1. Discussion: What sort of instances might cause damage to the turbine blades? (Possible answers: bird strike, collision with a vessel, storm, ice etc.)

2. Discussion: What problems might a damaged blade cause? (Possible answers: a damaged blade cannot generate properly; it might unbalance the other two blades until the whole turbine is affected. If a blade were to come loose it could strike another turbine blade, a vessel, sea creatures etc.)

3. Activity: Research how blade inspection is done. (Answer: a combination of photos from drones and reports from crew who need to use rope access to take a close look.)

a. If a drone is used, what issues might the drone have? (Answers: needs to be operated from a nearby vessel; weather (wind!); getting good resolution photos from a vibrating and moving drone; energy (battery) to power the drone.)

b. If a technician goes onsite, what issues are there with rope access? (Answers: time consuming; dangerous; can only be done in good weather; have to stop the turbine to access; training the inspection team; recording the findings.)

4. Discussion: What competing values or motivations might conflict in this scenario? Explain what constraints each engineer might be operating under and the potential conflicts between the roles.

5. Activity: Research what health and safety, environmental, and legal policies affect offshore wind farms. If they are in the open sea, which country’s laws are applied? Who is responsible for maintaining ecosystem health in the open sea? How are harms identified and mitigated?

 

Dilemma – Part two:

So, the blade engineer wants maintenance done effectively, with as little down time as possible; the H&S engineer wants it done safely, with as little danger to crew as possible; while the environmental engineer wants it done with as little damage to the ecosystem as possible. These three people must together develop an inspection plan that will be approved by upper management, who are largely driven by profitability – limited downtime in maintenance means increased profits as well as more energy delivered to customers.

 

Optional STOP for questions and activities:

The students are then presented with a brief that gives some background to the wind farms and the existing inspection regime. The brief is structured to allow engineering design, engineering drawing and technical research to take place alongside consideration of potential ethical dilemmas.

Brief: In teams of three, where each team member is assigned a different role outlined above (blade engineer, health and safety engineer, environmental engineer), propose a feasible method for blade inspection that:

Aspects to consider:

Teachers could task teams to work together to:

The pitch could include details of:

 

1. Activity: Working in groups, consider possible solutions:

a. Explore 2 or 3 alternatives to answer the need or problem, identifying the ethical concerns in each.

b. Analyse the alternative solutions to identify potential benefits, risks, costs, etc.

c. Justify the proposed solution.

 (Apart from the design process, this activity allows some discussion over the choice of solution. Looking at more than one allows the quieter students to speak out and justify their thinking.)

2. Activity: Working in groups, present a solution that consists of one or more of the following:

a. Make a CAD or drawn prototype.

b. Make a physical or 3D model.

c. Create a poster detailing the solution which could include technical drawings.

d. Presentation.

 

Students will be assessed according to:

a. Quality of final solution

b. Construction and testing of model

c. Innovation and originality

d. Communication skills
