Developing benchmarks for consumer-oriented life cycle assessment-based environmental information on products, services and consumption patterns

摘要

Life cycle assessment (LCA) has been recognized in the EU in the context of 'Integrated Product Policy' (IPP) as providing "the best framework for assessing the potential environmental impacts of products currently available." A study to promote the use of LCA-based product information was designed, with the following objectives: (a) to develop different benchmarks to which the LCA results of various products can be compared, (b) to study how consumers understand the different benchmarks and what proposals for improvement they have, and (c) to propose a few presentation formats and benchmarks for presenting LCA-based information in communications to consumers. Here we present the final results, i.e., the suggested benchmarks and presentation formats, 'eco-benchmark'. We also present some lessons derived from the feedback gained from consumers and other stakeholders, and point out future directions for improving the benchmarks and their utilization.
