Decision support

Chapter 41 in Elgar Encyclopedia of Life Cycle Sustainability Assessment, 2026, pp 143-145 from Edward Elgar Publishing

Abstract: Life cycle assessment (LCA) has been recognized as an important environmental systems analysis tool due to its potential for providing systematic results about the environmental impacts of alternative production and consumption systems that can lead to decisions towards greater sustainability in both private and public-policy contexts. However, LCA has been under increased scrutiny due to the wide range of published results on similar systems, which can be contrasting. This variability is, in part, due to the proliferation of guidelines that have emerged over the last 20 years, which may undermine the perceived robustness of LCA as a decision-support tool. The increased need for real environmental improvements means that it is of the utmost importance that LCA practice be harmonized, thereby allowing the results generated to be both reproducible and meaningful in expressing the likely consequences of alternative courses of action.
