Air emission

In order to reduce ambient air pollution, the Company focuses on limiting the amount of pollutants emitted from Ülemiste and Paljassaare boiler houses, particularly the pollutants of primary importance, such as nitrogen dioxide, carbon monoxide and volatile organic compounds, as well as CO2 greenhouse gas emissions. Also the emissions of ozone produced for drinking water treatment are regulated. The Company pays a pollution charge for pollutants emitted into ambient air.

Emissions from both Ülemiste Water Treatment Plant and Paljassaare Wastewater Treatment Plant have been relatively low and remained stable throughout the years. Also in 2015, there were no significant changes in this regard.
