This inventory report accompanies the annual emission inventory submission of the European Community to the UNECE Convention on Long-Range Transboundary Air Pollution. The report presents an overview of air pollutant emission data reported by the EU-27 Member States between the years 1990 to 2005. Across the EU-27, the reported emissions of nitrogen oxides in 2005 have decreased by more than 34 %, and sulphur dioxide by around 70 % since 1990. Significant reductions have also occurred for other pollutants during this period. The emission reductions have taken place across many of the economic sectors reported by countries transport, energy, agriculture and waste..
