Paper or plastic? Hybrid or conventional vehicles? Which is
better for the environment? To answer these questions, one must take
a holistic systems view using a quantitative approach known as life cycle
assessment.
Life cycle assessment (LCA) is a fundamental method for assessing the
environmental impacts of products and technologies from a "cradle to grave"
systems perspective. It is an essential tool for anyone who performs
environmental analyses or uses the results of such analyses for decision
making.
The course will provide an introduction to LCA methods and applications.
Students taking this course will emerge with a solid understanding of why
an LCA systems perspective is important, basic skills for sound application
of the LCA method and proper interpretation of its results, and an appreciation
for the strengths and limitations of LCA in practice. The course
will cover the four major steps in LCA: (1) goal definition and scope;
(2) life-cycle inventory compilation; (3) life-cycle impact assessment;
and (4) interpretation and management. The course will include a
hands-on modeling project, which the students will perform in parallel
to the lectures to reinforce learning objectives and to gain experience
in LCA application.
- The basics of energy and mass flows and exchanges with the environment
- Working with environmental data: strategies and pitfalls
- Study design: goal definition, system boundaries, and functional units
- Compiling the data: life-cycle inventory methods (process-based and
input-output methods)
- Understanding impacts: life-cycle impact analysis for land, air, water,
and health
- Dealing with data uncertainties: scenario, sensitivity, and uncertainty
analysis
- Results interpretation and system improvements
- Parting thoughts: advice and next steps for continuous learning
In this course you will learn the basics of the life-cycle assessment (LCA) method for holistic environmental analysis of products, technologies, and systems. LCA sheds light on the environmental implications of the consumption and behavioral choices we all make on a daily basis.
