The latest UN ECE protocol aims to minimise the damage caused by acidification, eutrophication, and ground level ozone (known as “Göteborg multi-component protocol”, s. NEC Directive of the EC, adopted in German law through the 33rd Ordinance – 33. BImschV) and obliges the Federal Republic of Germany to reduce NMVOC emissions to 995 kt by 2010.

Main drivers

NMVOC total emissions show a falling trend from 1990 onwards, with emission reductions of 69% between 1990 and 2012 with a bump in 2010 after the dent of 2008 and 2009 due to the economic situation. 2012 shows emissions close to the 2008/2009 levels again. The Main Drivers for NMVOC emissions are Fuel Combustion (NFR 1.A) with over 53% of total 1990 emissions and a 87% reduction between 1990 and 2012. In the Fuel Combustion category, Road Transport (NFR 1.A.3.b) is responsible for about three quarters of the 1990 emissions, with Passenger Cars (NFR 1.A.3.b.i) emitting nearly all of it. Reductions about 90% in those categories between 1990 and 2012 are mainly due to increasingly stricter regulations, especially incentives for automobile users to retrofit/buy cars with catalytic converters. Furthermore the implementation of the Technical Instruction on Air Quality Control (TA-Luft 2002), to decreases in emissions from petrol storage and from fuelling of motor vehicles (1.B.2.a.v) - as a result of implementation of the 20th and 21st Ordinances on the Execution of the Federal Imission Control Act (BImSchV) - and to reduced petrol consumption play a major role in the reduction of NMVOC emissions within the category Fugitive Emissions from fossil fuels (NRF 1.B.2). Substancial emissions also come from Paint Application (NFR 3.A) and Other Sources in Solvent and Other Product Use (NFR 3.D), as a sum (NFR 3) emitting over 37% of total 1990 emissions and a 43% reduction between 1990 and 2012.
