Sectoral shares of acidifying pollutants (SO2, NOx, NH3; energy and non-energy components) of total emissions, EEA-32. Values within the segments indicate the level of emissions (kt) emitted from each sector.: The emissions of acidifying pollutants (sulphur dioxide SO2, nitrogen oxides NOx and ammonia NH3) are each weighted by an acid equivalency factor prior to aggregation to represent their respective acidification potentials. The acid equivalency factors are given by: w(SO2) = 2/64 acid eq/g = 31.25 acid eq/kg, w(NOx) = 1/46 acid eq/g = 21.74 acid eq/kg and w(NH3) = 1/17 acid eq/g = 58.82 acid eq/kg.

Overall change in emissions of ozone precursors by country, 1990-2007: The graph shows the change in energy-related emissions of ozone precursors (NOx, NMVOC, CO and CH4) each weighted by an ozone formation factor prior to aggregation to represent their respective ozone forming potentials. The relative impact of the combined contribution of NOx, NMVOC, CO and CH4 to ozone formation can be assessed based on their tropospheric ozone forming potentials (TOFP): nitrogen oxides 1.22, non-methane volatile organic compounds 1.0, carbon monoxide 0.11 and methane 0.014 (de Leeuw 2002).

Sectoral shares of tropospheric ozone precursors (energy and non-energy components) in total emissions, EU-27.: The emissions of ozone precursors (NOx, NMVOC, CO and CH4) are each weighted by an ozone formation factor prior to aggregation to represent their respective ozone forming potentials. The relative impact of the combined contribution of NOx, NMVOC, CO and CH4 to ozone formation can be assessed based on their tropospheric ozone forming potentials (TOFP): nitrogen oxides 1.22, non-methane volatile organic compounds 1.0, carbon monoxide 0.11 and methane 0.014.

Changes (%) in emissions of ozone precursors by source category, 1990-2007, EEA-32 (weighted by tropospheric ozone forming potential): The graph above shows the emissions of ozone precursors (methane CH4; carbon monoxide CO; non-methane volatile organic compounds NMVOCs; and nitrogen oxides NOx) each weighted by a factor prior to aggregation to represent their respective tropospheric ozone formation potential (TOFP). The TOFP factors are: NOx 1.22, NMVOC 1, CO 0.11 and CH4 0.014 (de Leeuw 2002). Results are expressed in NMVOC equivalents (kilotonnes - kt). Data not available for Iceland (emissions of CO, NMVOC, NOx were not reported) and Malta (CO). 'Energy combustion' includes all energy-related emissions minus fugitive.

Total greenhouse gas emissions by sector (%) in EU-27, 2007: Annual emissions of CO2, CH4, N2O, HFC, PFC and SF6 in the UNFCCC reporting format are converted to their global warming potential GWP (100 year time horizon) for addition and comparison with the Kyoto Protocol targets: 1 t CH4 = 21 t CO2-equivalent, 1 t N2O = 310 t CO2-equivalent, 1 t SF6 = 23 900 t CO2-equivalent. HFCs and PFCs have a wide range of GWPs depending on the gas and emissions are already reported in tonnes CO2-equivalent. International transport emissions (Memo items: international aviation and international maritime transport) are shown in the chart because they are the fastest growing source of emissions in the EU. They are however not included in the national totals reported as part of the national greenhouse gas inventories under the UNFCCC.

Changes (%) in greenhouse gas emissions by source category in the EU, 1990-2007: International bunkers are international transport emissions (Memo items: international aviation and international maritime transport) and are shown in the chart because they are the fastest growing source of emissions in the EU. They are however not included in the national totals reported as part of the national greenhouse gas inventories under the UNFCCC. The sector LULUCF (Land use, land use change and forestry) is not included in the national totals under the UNFCCC either. LULUCF in the EU is a net carbon sink, resulting from higher removals by sinks than emissions from sources. A positive change in LULUCF means a reduction in emissions (i.e. a removal of emissions).

European Union emission inventory report 1990 — 2008 under the UNECE Convention on Long-range Transboundary Air Pollution (LRTAP): This document is the European Union emission inventory report under the United Nations Economic Commission for Europe (UNECE) Convention on Long-range Transboundary Air Pollution (LRTAP). It includes information on the formal institutional arrangements that underpin the European Union's emission inventory, emission trends for the EU‑27 and Member States, and the contribution of important individual emission sources to total emissions, sector group emission trends for key pollutants, information on recalculations and future planned improvements.

Is Europe's transport getting greener? Partly: While technological advances produce cleaner vehicles, more and more passengers and goods are travelling further distances, thereby offsetting efficiency gains. Based on analysis of long-term trends, a new European Environment Agency (EEA) report calls for a clear vision defining Europe's transport system by 2050 and consistent policies to achieve it.
