The 1999 Protocol to Abate Acidification, Eutrophication and Ground-level Ozone

The Executive body adopted the  Gothenburg protocol (GP) on 30 November 1999. The Protocol entered into force on 17 May 2005.      
 Status of ratification

The objective of the 1999 Protocol was to control and reduce emissions of sulphur, nitrogen oxides, ammonia and volatile organic compounds that are caused by anthropogenic activities and are likely to cause adverse effects on human health, natural ecosystems, materials and crops, due to acidification, eutrophication or ground-level ozone as a result of long-range transboundary atmospheric transport.

Once the Protocol is fully implemented, Europe’s sulphur emissions should be cut by at least 63%, its NOx emissions by 41%, its VOC emissions by 40% and its ammonia emissions by 17% compared to 1990.

Each Party having an emission ceiling in any table in annex II of GP shall reduce and maintain the reduction in its annual emissions in accordance with that ceiling and the timescales specified in that annex. Each Party shall, as a minimum, control its annual emissions of polluting compounds in accordance with the obligations in annex II.
