Life Cycle Sustainability Assessment—A Survey Based Potential Future Development for Implementation and Interpretation

Year: 2021

Type: article

Abstract: The aim of this study is to define, via an online expert survey, current challenges and possible future approaches in and for the implementation, application, and interpretation of the Life Cycle Sustainability Assessment (LCSA). Using an online survey, sustainability experts from around the world were surveyed over a period of five weeks, resulting in 71 experts answering 25 questions. The experts were invited by e-mail and through networks; the online questionnaire was the preferred survey choice particularly for reasons of time, cost, and the pandemic. The survey evaluation shows that no change in LCSA is needed. Nevertheless, (1) a detailed optional baseline LCSA framework, with pre-selected fixed indicator sets, (2) a supporting optional but unified visualization tool, (3) a clear and transparent communication on assumptions, targets and system boundaries and (4) early defined stakeholders were identified as relevant for further LCSA implementation and interpretation. Due to natural subjectivity, the results of this written survey are to be understood as recommendations for action and orientation, not explicitly as a prediction. Finally, an action outlook for future LCSA-development is given.
