This Swedish action plan provides municipalities with a framework for minimising and managing marine litter through local government responsibilities and activities. It focuses on identifying sources and pathways of litter, strengthening prevention and improving practical management. The plan is designed to help municipal departments understand where litter can arise, what measures can be taken and how responsibilities can be coordinated. It links local environmental management with the wider objective of reducing marine litter reaching coastal waters and the sea. The resource can support municipal planning, prioritisation and implementation of measures addressing litter prevention, collection, awareness and cooperation with relevant stakeholders.
