Source-to-sea framework for marine litter prevention

Building on a holistic view of how to tackle the problem of marine litter, the Source-to-Sea Framework for Marine Litter Prevention follows a six-step approach:

• Characterize the sources, types, behaviour and impacts of plastics in riverine and marine environments.
• Identify who is impacted by plastic pollution, both directly and indirectly, who contributes to plastic leakage and who can provide solutions.
• Diagnose how waste is managed /mismanaged and how the current governance framework is or is not preventing plastic from entering the riverine and marine environments.
• Describe the changes needed to prevent plastic leakage, e.g., governance, waste management services, infrastructure, behaviour change, design, production and use of plastic goods, etc.
• Develop interventions to prevent plastic leakage, at local to global scales and identify financing mechanisms for these interventions.
• Monitor the outcomes of the interventions, identify key uncertainties and gaps in knowledge that need to be addressed, disseminate learning globally and manage for progressive development.
