🌊How can we assess and address plastic pollution effectively to support a robust Global Plastics Treaty? Find out in our webinar series on methods for assessing plastic leakage!

​

We have officially wrapped up our PREVENT webinar series, “From Assessment to Action – Tackling Plastic Leakage for a Global Plastics Treaty”. This series explores different plastic leakage assessment methods at global, national, and local levels – highlighting how data-driven approaches can inform policies and actions to reduce plastic pollution. These assessments provide the data needed to set targets, track progress, and design effective policy measures for a strong Global Plastics Treaty.
