The Working Group on Strategies and Review (WGSR) is the principal negotiating body for the Convention. It assists the Executive Body in policy-oriented matters including: assessing scientific and technical activities relating to the preparation and revision of protocols; negotiating revisions to existing protocols and the preparation of new ones; reviewing draft guidance documents produced under different protocols; providing a forum for reporting on strategies, policies and measures; and preparing proposals for any strategic development under the Convention.
For these activities it works in close cooperation with the EMEP Steering Body and the Working Group on Effects. It also receives reports from the Task Forces on Reactive Nitrogen and on Techno-economic issues. Previous task forces worked on Heavy Metals, Persistent Organic Pollutants, Benefits and Economic Instruments, Particulate Matter and Ammonia Abatement.
