Purpose of this Handbook 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. Chapter 1 briefly outlines the ‘who’ and ‘what’ of LCA. Chapter 2 provides an extensive introduction to LCA methodology. Chapter 3 outlines a step by step procedure for building a model in GaBi. Please note that one example (a paper clip) is used throughout the video tutorial series and this handbook. 8
Introduction to Life Cycle Assessment 1 Introduction to Life Cycle Assessment This section of the handbook introduces the concept of Life Cycle Assessment (LCA). It is accompanied by Video 2, of the GaBi Paper Clip video tutorial series. 1.1 What is LCA? Figure 1: Overview of Life Cycle Assessment There are two LCA standards created by the International Organization for Standardization (ISO): the ISO 14040 and ISO 14044. Life Cycle Assessment, as defined by the ISO 14040 and ISO 14044 is the compiling and evaluation of the inputs and outputs and the potential environmental impacts of a product system during a product’s lifetime. Who uses LCA? LCAs are used by a variety of users for a range of purposes. According to the ISO standards on LCA, it can assist in: Identifying opportunities to improve the environmental aspects of products at various points in their life cycle; Decision making in industry, governmental or non-governmental organizations (e.g. strategic planning, priority setting, product and process design or redesign); Selection of relevant indicators of environmental performance, including measurement techniques; and Marketing (e.g., an environmental claim, eco-labeling scheme or environmental product declarations). 9
