Service contract: The impact of changes in vehicle fleet composition and exhaust treatment technology on the attainment of the ambient air quality limit value for NO2

Terms of Reference The contractor will have to undertake the following tasks: Compile and review any publicly available information relating to measured emissions of nitrogen dioxide and total NOx from the various vehicle categories across the EU. Assess the degree to which the annual average ambient air quality standard for nitrogen dioxide is likely to be exceeded in 2010 and 2015 within the EU. Assess the sensitivities of the conclusions reached under above, to changes in the proportions of directly emitted nitrogen dioxide in vehicle exhausts. Assess the extent and timeframe to which the predicted air quality exceedences would be reduced by new vehicle emissions standards for nitrogen oxide (NOx) emissions introduced after 2010
