- Abstract
This document discusses the importance of methodological requirements in comparative life cycle assessment (LCA) studies for single-use and reusable packaging and products. The authors emphasize that variations in assumptions, functional unit, and system boundaries can significantly impact the results of LCAs. They argue that studies comparing reusable and single-use packaging should include sensitivity and scenario analyses to determine the break-even point, which is the minimum number of times a reusable product must be used to be considered environmentally better than single-use products. The authors also propose a list of criteria that LCA studies should meet to ensure scientific robustness and objective impartiality. They highlight the need for peer-reviewed and independent studies that follow ISO LCA standards and evaluate the full life cycle of the products. The authors caution against relying on LCA studies that do not meet these requirements, as they may lack reliability and mislead decision-makers.
