Review of the global evolution of regulations on single-use plastics and lessons drawn for Canada.

Plastic pollution is a global problem and many countries are strengthening their regulations to mitigate the related environmental degradation and health risks and to support the development and deployment of circular economy for various types of plastics. As Canada also develops its strategy for regulating single-use plastic as one element of the plastic pollution, aligned federal and provincial policies are essential. This study presents an analysis of existing and emerging policies to provide guidance on Canada's future regulations. Qualitative and quantitative data regarding plastic regulations were gathered from similar countries including Australia, the United Kingdom, the European Union, the United States and relevant scientific articles. Analysis was also conducted of current Canadian regulations that both impact and guide the path for plastic regulation, international examples provided guidance for future Canadian regulations. The analysis found that there is a need for public education on the gravity of plastic pollution to gain their support; for establishing pioneering provinces or cities in plastic regulations to learn from and provide other cities with support; and to start with banning items with available alternatives, to be followed by phasing out other items that are more difficult to replace. The study also showed potential areas of improvement in impact data. The need for reliable regulatory performance data against a baseline scenario; consistency in methodology; and proper scoping to reduce the risk of displacement or exclusivity in policy were identified.
