While gas-fired power plants emit greenhouse gases, they are an environmentally friendly alternative to other carbon-based energy sources. Gas-fired power plants constructed with the best technology currently available emit around 50% less CO2 than coal power plants. As the first of its kind, the Kårstø plant has been constructed with its own NOx cleaning facilities.

District heating is produced by incineration of various energy sources, which produces CO2 emissions. In 2007 incineration resulted in emissions of 55,700 tonnes of fossile CO2.  The percentage of heat generation based on waste is between 70 % to 80 %. This means that around 120,000 tonnes of waste is converted to heat  in the Group’s plants.

Other emissions of greenhouse gases stem from transport from the Group’s own vehicle fleet and the accidental discharge of halon and SF6. 

From 2008 the Group has purchased climate quotas in the voluntary carbon quota market for greenhouse gas emissions resulting from transport and environmental non-compliances.
