Policy issue:  Meet EU and/or international emission reduction targets for 2010


Key assessment

Transport emissions of acidifying substances, ozone precursors and particulates decreased by 26, 35 and 24 %, respectively, between 1990 and 2001 in EEA-31. This was mostly a result of emission reductions realised in road transport, which in turn was due to the increased use of catalytic converters, reduced sulphur concentrations in fuels and fleet renewal. However, further reductions for all substances will be required from all sectors in order to achieve the various environmental targets set for 2010. Unlike the steady decline of emissions from EU-15, Iceland, Lichtenstein and Norway, in AC-10 emissions of acidifying substances, ozone precursors and particulates decreased by 16, 16 and 22 % between 1990 and 1993 but then remained largely stable until 1998 before decreasing further in 1999-2001 to 61, 59 and 67 % of the 1990 levels respectively. The initial sharp decline in the early 1990s was mainly due to the economic recession that impacted strongly on traffic volumes. The stabilisation of emissions, despite rising transport volumes in the second half of the 1990s, was a result of fleet renewal. Emissions from CC-3 fluctuated in the same period, ending down by 16, 12 and 18 %.
