Module overview

When considering how to reduce the environmental impacts of a product, a service, an organisation, a household or even a nation, it is vital to take a life cycle approach. In this module we introduce participants to life cycle thinking, the concept of the circular economy, life cycle management and related environmental systems analysis approaches. We consider how such approaches can guard against trade-offs in sustainability, thus leading to better-informed decisions.

Module aims

This module aims to:

Introduce participants to life cycle thinking, the concept of the circular economy, life cycle management and related environmental systems analysis approaches.

Learning outcomes

On successful completion of this module, students will be able to:

  • Explain the concept of life cycle thinking (LCT) and describe the benefits and challenges of its application in practice in industry and for policy making. (K, T, P)
  • To appreciate and be able to discuss the strengths and weaknesses of the circular economy concept (K, T, P)
  • Describe the goal, key methodologies, challenges and role of systems analysis approaches such as Life Cycle Assessment (LCA) and Input-Output Analysis. (K)
  • Appreciate different types of footprints, appropriate methodologies, and to be aware of current protocols and standards used for carbon footprinting of products, services and organisations. (K, P)
  • Apply the principles and tools of Design for Sustainability to consumer products. (C, P).

Key: C-Cognitive/Analytical; K-Subject Knowledge; T-Transferable Skills; P- Professional/ Practical skills.

Module content

Indicative content includes:

  • Introduction to life cycle thinking, the circular economy, and life cycle management
  • Concepts, policy and organisational drivers, and application in practice
  • Introduction to Life Cycle Assessment methodology, simplified life cycle studies; and case studies (from academia and industry)
  • Overview of Input-Output Analysis: principles and application
  • Principles and practice of Design for Sustainability.

Methods of teaching/learning

The learning and teaching strategy is designed to take an active learning approach, in which the students are engaged in class exercises and discussions. The schedule includes guest expert speakers from industry with whom students are encouraged to engage.

The learning and teaching methods include:

  • Preparatory reading (10 hours)
  • Lectures (18 hours)
  • In-class exercises and group discussions (12 hours)
  • Post course study and assignment (110 hours).

Assessment strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate that they understand the concepts of life cycle thinking (LCT) and the circular economy, and are able to discuss the benefits and challenges of its application in practice in industry and for policy making. In the individual assignment students are asked to demonstrate their understanding by applying what they have learnt to case studies. In the group assignment they are asked to apply the principles of Design for Sustainability to a specific consumer good or service.

Thus, the summative assessment for this module consists of:

  • An Individual Post Module Report in which students are instructed to utilise case studies to critically explore how life cycle thinking can be applied to improve sustainability outcomes. Assignment length: 3,200 words maximum (excluding reference list). Deadline: 3 weeks after the end of the module
  • An In-class Group Work Report in which students apply the principles and tools of Design for Sustainability to a selected consumer product. Deadline: close of play on the day of the exercise. In cases where the In-class Group Work Report is failed, the alternative assignment will be an individual report, 800 words maximum.

Formative assessment and feedback

Students receive formative feedback during in-class group exercises and discussions. Groups are generally around 6-7 students.
