Emission trends for the main air pollutants, PM, HMs and POPs

Note: Parties to the Convention on Long-range Transboundary Air Pollution (LRTAP) are formally requested to report emissions of PM only for the year 2000 and onwards. Hence emission trends for these years only are shown. PM₁₀: particulate matter with a diameter of 10 μm or less; PM_2.5: particulate matter with a diameter of 2.5 μm or less; TSP: Total suspended particulate; NMVOC: Non-methane volatile organic compounds; NH₃: ammonia; NO_X: nitrogen oxides; CO: carbon monoxide; SO_X: sulphur oxides.
