Under the LRTAP Convention, Parties are requested to report emission data for a number of important air pollutants, including sulphur oxides (SOX), nitrogen oxides (NOX), non-methane volatile organic compounds (NMVOCs), ammonia (NH3), carbon monoxide (CO), heavy metals (HMs), persistent organic pollutants (POPs), and primary particulate matter (PM).
The subsequent sections of this report provide general information on the institutional arrangements and data sources that underpin the European Community's LRTAP Convention Inventory (Chapter 1), emission trends by pollutant
(Chapter 2), the contribution made to emissions by key categories (Chapter 3) and the recalculations that have been made to previously-reported emission estimates (Chapter 4) by the EU-27 Member States (MS) *).
Due to gaps in the data reported by MS, aggregated EU-15 *) and EU-12 *) totals have been calculated for NOX, CO, NMVOCs, SOX, and NH3 only. Across the EU-27, the reported emissions of nitrogen oxides in 2005 had decreased by more than 34 %, and sulphur dioxide by around 70 % since 1990. Significant reductions have also occurred for the other pollutants during this period. A reduction in emissions has taken place across many of the sectors
reported by countries including transport, energy, agriculture and waste.
