The study identifies and elaborates options for the basic financial set-up and approaches to resource mobilisation and delivery that ensure an effective national and international operation and implementation of a global agreement on plastic pollution. Four key messages stand out:1. The transition to a more circular global plastics economyprovides significant environmental, economic and social opportunities.2. The current availability, mobilisation and provision of public and private financial resources is overall insufficient3. Substantial contributions from business actors in the global plastics economy are needed to mobilise and provide sufficient financial resources.4. An effective global agreement on plastic pollution can establish a legislative framework that stimulates necessary investments and that assists countries in mobilising and delivering financial resources.
