Online Course Objectives

Our Impact Assessment Methods course delves into the science behind the evaluation of the effect of emissions on the environment. We will demystify how impact assessment methods are modeled and calculations made.

This interactive online training course provides an overview of commonly used and accepted impact assessment methods, including background on how these methods model the fate, transport and exposure pathways (causality chain) of emissions, allowing you to understand each impact category and why your results change when you use different impact assessment methods. The class will point out the strengths and weaknesses of the major internationally accepted impact assessment methods, allowing you to choose the best approach for your life cycle assessment (LCA) study.

Using slides, your instructor will visually show you the structure of impact assessment and how various impact categories are assessed.
