This report presents a framework for preventing marine litter based on the source-to-sea conceptual framework presented in Granit et al., 2017 and the practitioners’ guidance for implementing the source-to-sea approach in Mathews et al., 2019. Addressing issues from the holistic perspective of the source-to-sea system and strengthening coordination between sectors is central to the source-to-sea approach. The Source-to-Sea Framework for Marine Litter Prevention is intended to be useful when determining measures concerning governance, management, practices and behaviour which facilitate progress toward a reduction in the quantities of plastic entering the oceans. It can guide both the public and private sectors in addressing the issue of plastic waste in rivers and oceans.
