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.

When the situation in Graph 23 of the 1990-2016 emissions covered by the 2018 reporting is examined; it is observed that there has been a significant decrease in some pollutants caused by combustion especially in recent years. This may be due to reduced fuel consumption in power plants and updated emission factors due to changing technologies. However, there is an increase in emissions compared to 1990 levels, highest increase was observed in NOx emissions with a rate of 63%, followed by SO2 and the other pollutants.

When the emissions compared to 2015 are examined; PM10 and CO emissions decreased by 12% and 9%, respectively, while other emissions are increased. changes in emissions both in time series and compared to the previous year are given in Table 9.

In 2016, for SO2 65.1% of the emissions were caused by energy production-power plants, 12.9% by residential heating. 47.2% of NOX emissions were caused by energy production-power plants and 9.3% by heavy-duty vehicles. Animal waste caused 18.9% and residential heating 13.3% of the total NMVOC emissions. Main reasons of the NH3 emissions were livestock farming.

Anthropogenic emissions of the main air pollutants decreased significantly in EU-28 countries between 1990 and 2016; NOX emissions decreased by 58%, SOX emissions by 91%, NMVOC emissions by 62%, NH3 emissions by 23% and PM2.5 emissions by 28% [27].
