5.1 Especially critical in LCAs conducted to compare products
5.1.1 Plastic VS. Paper bag
6 Uncertainty in Results of Life-Cycle Inventories
6.1 • Use of regional or global data

7 SUMMARY
7.1 • Assumptions made when choosing system boundaries and data sources
7.2 • LCAs are a tool for assessing and minimising the impact of human activities.
7.3 • Life-cycle stages of a product include raw material acquisition, manufacturing, use and disposal.
7.4 LCA techniques have been adopted in industry and the public sector to serve a variety of purposes.
7.5 • Choices made during the planning phase of an LCA have a profound impact on the results obtained. The choice of functional unit, particularly when LCAs are conducted to compare products, is especially influential.
