In a recent reportMcKinsey examines the performance of plastic against its most commonly used alternatives for industries including packaging and consumer goods, in a bid to understand where its environmental advantages emerge. The company found that plastics offer lower greenhouse gas (GHG) emissions than alternatives in 13 out of 14 cases, including for grocery bags, beverage containers, pet food packaging, and fresh meat packaging.

Recent studies, for example, have helped to quantify annual flows of plastic into oceans or highlighted the need for further research into chemicals of concern in plastic packaging that comes into direct contact with food.
