This report focuses on the actions and responsibilities of four of the world’s biggest plastic polluters: CocaCola, Nestlé, PepsiCo and Unilever. These companies continue to sell billions of products in single-use bottles, sachets and packets in developing countries. And they do this despite knowing that: 1) waste isn’t properly managed in these contexts; 2) their packaging therefore becomes pollution; and 3) such pollution causes serious harm to the climate and people’s health. In this report, we present the first estimates of the greenhouse gas emissions created by the open burning of each company's plastic waste in six focus countries. The challenge is clear: companies need to step up the pace and scale of their action on plastic, the burning question is: are they up to it?
