This article presents a first scholarly review of the trade policies and measures applied to trade in plastics, including those relevant to plastic pollution. It reviews existing tariff policies applied to plastics (section 1) and non-tariff measures applied to plastics (section 2). Section 3 provides a synopsis of environment-related trade measures relevant to plastic pollution. Analysis of the current state of play provides important insights that can inform both the United Nations ongoing discussions on intergovernmental cooperation to address plastic pollution and the dialogue underway at the WTO to identify how trade related policies could support the Sustainable Development Goals.
