10 November 2021 – Gland, Switzerland: Created to assist new users who wish to apply the UNEP/IUCN National Guidance for plastic pollution hotspotting and shaping action methodology, this Tutorial and its six videos take users through a national hotspotting assessment by following a step-by-step workflow. The links to the relevant videos can be found in the relevant chapters of the tutorial document as well.

The core of the methodology and requirements is presented to help users visualise the journey from data collection to intervention identification to detailed GIS modelling. With precise directions and video content, the document elaborates the 29 steps to conduct a national plastic pollution hotspotting assessment. A flowchart of each phase (A, B, and C) illustrates the data needed, the technical and strategic tools to use, how to verify results, and in which order to generate the necessary outcomes that can be synthesised as evidence and guidance for policy makers.
