Key policy question: Is the contribution of the transport sector to air quality reducing?

Key messages

The data analysed from selected stations in major urban agglomerations, indicate that during the period 1999-2007 mean values of NO2 concentrations at road traffic stations remain relatively stable (trend is smaller than the statistical uncertainty on estimate) whereas an increase is observed in the maximum observed concentrations after 2003 and then again a slight reduction in 2007. The background concentrations remain relatively stable throughout the period 1999-2007. For PM10, a slight increase was observed in 2003 in the maximum background concentrations, but these have followed a downward trend since. In 2004 and 2005 a reduction was observed in the maximum concentrations at traffic stations, but this trend was not continued in subsequent years. Throughout the period 2002-2007 mean traffic and mean background concentrations remain relatively stable, with a slightly downward trend observed in the mean background concentrations.

Key assessment

In 2007 road transport still remained the largest contributor to NOx emissions in the EEA, the second largest contributor to particulate formation pollutants overall (PM10, SO2, NOx and NH3) and primary PM2.5 and the third largest contributor for primary PM10. Despite the significant reduction of NOx, SO2, CO, PFP and TOFP (Total Ozone Formation Pollutants) road transport emissions achieved since 1990 across the EEA, the decrease in emissions does not appear to have a statistically significant influence on the air quality in urban agglomerations and the increase in the number of vehicles is off-setting the technological and fuel quality improvements. During 1999-2007, the maximum NO2 concentration at traffic stations is observed in London, whereas the maximum background concentration is observed in Paris. The maximum PM10 traffic value during 2002-2006 was observed in Rome, but as data from the traffic station was not available in 2007 the maximum PM10 traffic value for this year was observed in London. The maximum background concentration is observed in Prague for the period 2002-2004 and 2006-2007 and in Bratislava for 2005.
