(Reuters) - The widespread adoption of returning and reusing plastic packaging could help to cut greenhouse gas emissions by up to 69%, a study by the Ellen MacArthur Foundation showed on Wednesday.

 

Such schemes not only lower companies' emissions but can also drive down costs for some items, according to the study covering over 60 organisations including national governments and consumer goods companies such as Danone, Nestlé, PepsiCo and Unilever.
