Pollution

Pollution from our activities is mainly related to NOx emissions from gas power plants and district heating plants and emissions of SO2 from district heating plants.

The operation of gas power plants and district heating plants causes NO_x emissions. The emissions increased in 2009 due to the fact that we took over two new gas power plants through the E.ON agreement. District heating plants also cause SO_x emissions and discharge of spill water.

The activities can also result in some accidental emissions of gases, primarily halon and SF₆. There is also some risk of oil spills from vehicles, construction machinery and production equipment. Noise can occur locally in connection with transport and operation of plants, and there are some thermal discharges to water in connection with gas power plants.

In 2009, emission of 105 kg of SF₆ and 183 kg of halon were recorded. In addition, several minor oil spills were recorded, but none of them had any significant negative environmental effects.
