The main priorities under the Convention Implementation of and compliance with protocols in force: 1985 and 1994 Sulphur Protocols 1988 NOx Protocol 1991 VOC Protocol Review and extension of protocols: 1998 POPs and Heavy Metals Protocol 1999 Gothenburg Protocol to Abate Acidification, Eutrophication and Ground-level Ozone

Intergovernmental bodies, expert groups and scientific centres under the Convention

Covered by benefit assessment The multi-pollutant, multi-effect approach of the Gothenburg Protocol extended by PM Primary PM PM pollution Covered by benefit assessment

Effects included in the assessment made before the Gothenburg Protocol Health (aerosols, ozone, SO2) Acute, chronic - mortality and morbidity Materials SO2 / acid effects on utilitarian buildings Crops/Forests Direct effects of SO2 and O3 on crop yield Indirect SO2 and O3 effects on livestock N deposition as fertilizer Acidification/liming O3 effects on timber production Visibility Change in amenity Ecological damage - missing

The Gothenburg Protocol review The review will commence the review in 2004 (dependant on entry into force in 2003) Re-examine acidification, eutrophication and ground-level ozone damage Use 2015 and 2020 as target years (to be re-evaluated in the light of data quality and uncertainty) Cover PM and its health impacts Take into account hemispheric air pollution and, possibly, synergies with climate change policies

Economic assessment of air pollution abatement benefits remains a high priority area of work
