Plastic pollution is a major threat to the oceans, with litter reaching alarming levels. Stakeholders recognize the need for effective strategies to limit plastic discharge, including bans, accountability measures, and awareness-raising efforts. However, assessing the success of these actions is challenging due to the lack of standardized measurement methods. Accurate data is essential for decision-makers to tackle plastic pollution effectively.
The purpose of this report is to conduct a review of the existing methodologies which assess plastic waste flows and leakage into the environment and more specifically, plastic leakage into waterways and entering oceans and seas.
By developing a comparative framework, the reader can find support in identifying the methodology which best enables monitoring projects or national programs to be assessed within their context of application and in terms of their added value for preventing plastic pollution and marine litter.
