5.1- Air Pollutant Emissions

An important pressure indicator is identified as the emissions of air pollutants  and shows the amount of national emissions of major air pollutants by years and source sectors.

Within the reporting requirements of the UNECE CLRTAP (United Nations Economic Commission for Europe, Convention on Long-Range Transboundary Air Pollution (CLRTAP),  a national air emissions inventory for, NOX (nitrogen oxides), SO2 (sulphur dioxide), NMVOC (non-methane volatile organic compounds), NH3 (ammonia), PM10 (particulate matter) and CO (carbon monoxide) is prepared each year by the Ministry of Environment and Urbanization and reported to the UNECE Secretariat through European Environment Agency, comprising the inventory data of the second previous year. In this book, latest available data belongs to 2015.

General increase was observed in the trend of emissions between 1990 and 2015, despite a small decrease of combustion emissions within recent years.

Compared to the 1990 emissions data, NOX emissions showed a high increase with a percentage of 57%, followed by NMVOC and other emissions respectively.

Compared to the emissions in 2014, SO2 and NH3 emissions decreased by 9.7% and 2.7%, respectively. Other emissions appear to be increasing. Table 12 shows the emission changes compared to 1990 and the previous year.

In 2015, for SO2 61.8 % of the emissions were caused by energy production-power plants, 14.3 % by residential heating. 27.3 % of NOX emissions were caused by heavy-duty vehicles and 30.5 % by energy production-power plants. Residential heating caused 15.5% and animal waste 17.9 % of the total NMVOC emissions. Main reasons of the NH3 emissions were synthetic fertilizer use and livestock farming.

Anthropogenic emissions of the main air pollutants decreased significantly in EU-28 countries between 1990 and 2015; NOX emissions decreased by 56%, SOX emissions by 89%, NMVOC emissions by 61%, NH3 emissions by 23% and PM2.5 emissions by 26% [25].
