Public and private sector efforts for reuse solutions have increased significantly in the last years. Notably, leading consumer goods companies have set commitments and implemented plans, amid a burgeoning innovation landscape. New policy frameworks such as the European Union’s Packaging and Packaging Waste Regulation and the forthcoming United Nations Plastics Treaty will provide additional ballast to mainstream reuse systems.Against these developments, it is becoming urgent to harmonize the way in which standards are set and progress measured. A fragmented approach in target-setting and measurement would slow down the widescale adoption of reuse models, create inconsistency in the quality of reporting and lead to a loss of consumer confidence.It is with this objective in mind that the World Economic Forum’s Consumers Beyond Waste initiative has been convening a multistakeholder working group since early 2022 to discuss reuse guidelines and standards.This white paper provides guidance on standardized reuse measurement and offers corporate stakeholders, policy-makers, standard-setters and ecosystem actors a framework to track success on reuse models. It is the culmination of working group member inputs and based on recommendations from the team. Select companies in the group also piloted a preliminary version of the guidelines agains...
