Emission ceilings

In Europe the regional air pollution is regulated by a number of protocols under the UNECE CLRTAP (United Nations Economic Commission for Europe Convention on Long Range Transboundary Air Pollution) Convention.

The objectives of the new protocol – the Gothenburg Protocol – is to control and reduce the emissions of SO2, NOx, NMVOC and NH3. In contrary to the former protocols the parties to the convention are not obliged to comply with certain reduction ratios from a baseline year. Instead emission ceilings have been set from the knowledge of critical loads and environmental impact on ecosystems within the geographical area of Europe. The table shows the emission ceilings for Denmark in 2010 together with the emissions in 2010.

Emission ceilings 2010

The same emission ceilings are given in the following EU directive also called the NEC-directive:
Directive 2001/81/EC of the European Parliament and of the Council of 23 October 2001 on National Emission Ceilings for certain atmospheric pollutants.

Regional air pollution is regulated by a number of protocols under the United Nations Economic Commission for Europe (UNECE) Convention on Long-Range Transboundary Air Pollution (CLRTAP). The objectives of the most recent of these protocols – the Gothenburg Protocol – is to control and reduce emissions of SO2, NOx, NMCOV and NH3 in order to reduce exceedances of critical loads with regard to acidification, eutrophication and the effect of photochemical air pollution (ozone). In contrast to the earlier protocols, the individual countries are not obligated to achieve a certain reduction target, but emission ceilings have been set in order to reduce exceedance of the critical loads, based on the knowledge of critical loads and effects on the ecosystems within the geographic area of Europe.

In 2012 the Gothenburg Protocol was amended to establish emission reduction commitments for 2020 and beyond. Furthermore, reduction commitments for particulate matter (PM2.5) were introduced for the first time. In the amended Gothenburg Protocol, the reduction commitments are given as a percentage reduction compared to the emission level in 2005. The emission ceilings for Denmark in 2010 according to the Gothenburg Protocol are shown in Table below together with the reduction percentages for 2020 recalculated to a “ceiling” value.

Emission ceilings for air pollutants

The emission ceilings for 2010 are also included in the EU directive: Directive 2001/81/EC of the European Parliament and of the Council of 23 October 2001 on national emission ceilings for certain atmospheric pollutants. A revision of the National Emission Ceilings Directive is expected to be initiated during 2013.
