Key assessment

Since 1990 NOx EU15 emissions have decreased by 25%. The decrease between 1999 and 2000 was 1.3%. The anthropogenic emission of NOx originates mainly from the road transport sector (46%). The main sources of NOx in 2001 were: road and other transport (a combined contribution of 61% of total NOx emissions), energy industries (18%) and industry (14%).
Since 1990 the emissions from road transport have been reduced by 28% and emissions from the energy sector by 38%. The emission reduction is mainly due to the introduction of catalysts on new cars in Western Europe and improved abatement and the introduction of Combined Cycle Gas Turbine (CCGT) power generation in the energy and industry sectors. Increasing road travel has, however, partly offset reductions achieved by emission abatement.
