Key policy question: Are emissions of acidifying substances, particulates and ozone precursors from transport decreasing?

Key messages

With the exception of NH3, transport related emissions of all main contributors to acidification and particulate and ozone formation (CO, CH4, NH3, NOx, NMVOCs, SOx and primary particulates (PM10 and PM2.5)) decreased in the EEA-32 between 1990 and 2008. The maximum of transport related NH3 emissions in the EEA-32 was reached in 2000. NH3 contributes to both acidification and particulate formation.

Transport emissions of acidifying substances in EEA member countries

Note: Transport emissions of acidifying substances (NOx, SOx, NH3) in EEA member countries. The transport emissions data include all of road transport and other transport/mobile sources, less the memo items, which include international aviation (LTO (Landing and Take Off) and cruise) and international marine (international sea traffic- bunkers).

Key assessment

Acidifying substances

In the EEA-32 transport emissions of SOx and NOx were reduced by 68 and 32 % respectively between 1990 and 2008. The introduction of both catalytic converters and reduced sulphur in fuels has contributed substantially to this reduction, offsetting the pressure from increased road traffic in the same period. For the EEA-32 NH3 emissions from transport contributed only 2 % to total NH3 emissions in 2008. However, transport related NH3 emissions increased by 330 % in the EEA-32 between 1990 and. The NH3 emissions from road transport, have been rising as a result of the increasing use of three-way catalytic converters in the vehicle fleet (this is due to an unwanted reaction involving hydrogen which reduces NO to NH3). However, emissions are projected to fall in the future as the second generation of catalysts (which emit lower levels of NH3 than the first generation catalysts) penetrate the vehicle fleet.
The EU-27 contributed 89, 87 and 96 % to transport related NOx, SOx and NH3 emissions of the EEA-32.

Ozone precursors

Within the group of the ozone precursors (CH4, NOx, NMVOC and CO) transport emissions of all pollutants decreased (64, 32, 72 and 71 % respectively) in the EEA-32 between 1990 and 2008. Reductions have occurred mainly because of increasing prevalence of catalytic converters for road vehicles and as a result of tightening of EU regulations on new vehicle emissions limits.
The EU-27 contributed 87, 89, 82 and 89 % to transport related CH4,CO, NMVOC and NOx emissions of the EEA-32.

Particulate matter

The secondary inorganic particulates (NOx, SOx and NH3) precursors are the same as the acidifying substances. Their trends are described above. In the EEA-32 transport emissions of PM10 and PM2.5 were reduced by 21 and 31 % respectively between 1990 and 2008. Particulate filters contributed to the reduction of primary particulates from transport.
The EU-27 contributed 97 and 98 % to transport related PM10 and PM2.5 emissions of the EEA-32.
