AG2800 Life Cycle Assessment 7.5 credits

Livscykelanalys

Products, services, and infrastructure cause environmental impact over their entire life cycle - from raw material extraction, through use, to waste management. LCA is a methodology to quantify impacts over the life cycle. It’s used to identify environmental hotspots and avoid problem-shifting. LCA and life cycle thinking is used for decision-making in industry and public planning and policy making. In this course, you learn the basics of the methodology, learn to use LCA software, and practice in projects.

Course information

Content and learning outcomes

Course contents *

The course includes lectures and a group project. Lectures will cover the following areas:

  • LCA in relation to other environmental systems analysis tools.
  • Methodology for the different phases of an LCA (goal definition and scoping, inventory analysis, impact assessment and interpretation).
  • Methodology for simplified LCA.
  • LCA software tools and databases.
  • Critical review of an LCA study.
  • Application areas of LCA and limitations.

Intended learning outcomes *

The overall aim of this course is to develop your skills of systems thinking in environmental issues, related to your own area of expertise. This course will give you a basic analyst’s competence in Life Cycle Assessment (LCA).
After completing the course, you should be able to: 

  • Explain the overall purpose and principles of LCA.
  • Discuss possible applications and limitiations of LCA.-Describe the content and explain the purpose of the analytical steps of LCA.
  • Carry out a complete LCA of a product or service system, including:  
    1. identify and delimit the system,  
    2. specify and handle allocation problems,  
    3. identify and use relevant data from LCA databases,  
    4. collect and use data from other sources,  
    5. choose characterisation method based on coverage and relevance to the intended application,  
    6. implement and use a computer model of the system in the LCA software SimaPro,  
    7. analyse, explain, and interpret model results.
  • Write a report of the performed LCA, applying to the reporting guidelines and terminology as defined in the ISO standard for LCA.
  • Make a critical review of another LCA.

Course Disposition

The course includes lectures and a group project. Groups of 2-4 students will perform projects in which an LCA is performed with the software SimaPro. Projects are presented in a report and at a seminar. Each group will also make a critical review of the LCA of another group.
