Reusable packaging is in general a more sustainable choice compared to single-use packaging. Research shows that when scaled effectively, reuse systems have (1) a lower carbon impact per use, (2) higher resource efficiency per gram, and (3) lower likelihood of contributing to mismanaged waste such as littering. It is therefore correctly identified by leading organisations such as WWF and Ellen Macarthur Foundation as critical to addressing the current environmental crisis. This is also confirmed by leading coalitions of private sector economic operators, for example the Global Commitment 2022 endorsed by more than 500 organisations (>350 companies) and the Plastic Pacts signed up in many European countries.
