Introduction to LCA (learning about Life Cycle Assessment) and modelling using GaBi

The purpose of this handbook is to support your learning about Life Cycle Assessment (LCA). We understand that learning new concepts can be difficult. And everyone has different ways of learning. Some people react best to visual learning, some aural. Some need to draw relationship charts. Some need to read and read and read and some are lucky enough just to absorb everything. Through the GaBi Learning Centre we’re trying to provide ways of learning that appeal to most of you. This handbook is intended to support the video tutorials found in the GaBi Learning Centre but can also be used completely independent from them. After completing the video tutorials or stepping through the content contained in this handbook you should: • Understand the concept of LCA; • Be able to build an LCA model using the GaBi software.

Please note that one example (a paper clip) is used throughout the video tutorial series and this handbook. Startint with chapter 3 the tutorial will outline a step-by-step procedure for conducting an LCA in GaBi. It contains two types of text: 1. Numbered text indicates that a step should be completed. Text in italics provides explanatory comments about why you might do something or how something works. You will also notice that there are headings scattered throughout the procedure. These correspond (mostly; there are a couple of extra headings here) with the contents found in the video tutorial. The titles let you know what video chapter you are up to.
