Emissions to air (EN20)
CO2 is the predominant emission to air from Vattenfall’s operations, see Greenhouse gas emissions (EN 16–18).
Other emissions to air include SO2, NOX and particles, which have decreased in recent decades due to the modernisation of generation facilities and installation of flue-gas cleaning equipment. In 2008, decisions were made to further invest in flue gas cleaning in Poland, see also Technology as a tool to cut emissions.

Emissions of SO2, NOX and particles per kWh of generated energy from Vattenfall’s power plants are decreasing steadily as a result of improved flue gas cleaning and increased generation from low-emitting energy sources. A significant proportion of the reduction of NOX emissions is a result of the installation of SCR equipment at the Fyn Power Plant in Denmark in early 2008.
