Introduction to Life Cycle Assessment The following is just a brief list of the groups that use LCAs and of the possibilities that an LCA could be used for. 1.1.1 Industry Large companies use LCAs as a way of identifying environmental hot spots and to develop and advertise their environmental management strategies. LCA studies are often conducted by industry associations and environmental concepts and tools research organizations including the: Canadian Wood Council; International Copper Association; International Lead and Zinc Research Organization; International Iron and Steel Institute; International Aluminum Institute and the Nickel Development Institute. 1.1.2 Government Governmental departments around the world are active promoters of LCA. Governments use LCA for data collection and developing more effective environmental policies related to materials and products. 1.1.3 Universities There are many universities researching and developing LCA methodology and data. 1.2 How is an LCA created? The ISO 14040 standard provides an introduction to LCA and contains applicable definitions and background information. The ISO 14044 describes the process of conducting an LCA. The detailed procedure for LCA, outlined in Chapter 2, is in accordance with the standards ISO 14040 and ISO 14044. 1.3 GaBi overview With features refined through experience on thousands of PE consulting projects, GaBi supports every stage of an LCA, from data collection and organization to presentation of results and stakeholder engagement. GaBi automatically tracks all material, energy, and emissions flows, as well as defined monetary values, working time and social issues, giving instant performance accounting in dozens of environmental impact categories. With a modular and parameterized architecture, GaBi allows rapid modeling even of complex processes and different production options. This architecture also makes it easy to add other data such as economic cost or social impact information to a model, making GaBi a holistic life cycle analysis tool. The GaBi software is complemented by the most comprehensive, up-to-date Life Cycle Inventory database available. With over 4,500 Life Cycle Inventory datasets based on primary data collection during our global work with companies, associations and public bodies GaBi Databases span most industries. . 10
Conducting Life Cycle Assessments 2 Conducting Life Cycle Assessments Life Cycle Assessments are conducted according to the ISO 14040 and ISO 14044 standards. LCAs consist of four steps, as shown in Figure 2: 1. Goal and Scope Definition 2. Inventory Analysis 3. Impact Assessment 4. Interpretation These four steps are described in detail in the following sections. Figure 2: Steps of a Life Cycle Assessment According to ISO 14044 2.1 Goal and Scope Definition According to the ISO 14040 standard the first phase of an LCA is the definition of the goal and scope. In this step all general decisions for setting up the LCA system are made. The goal and scope should be defined clearly and consistently with the intended application. An LCA is an iterative process and this allows redefining the goal and scope later in the study based on the interpretation of the results. 2.1.1 Goal In the goal definition, the following points need to be determined: 11
