Charge for emissions of nitrogen oxides

Companies who are subject to the Environmental Charge for Emissions of Nitrogen Oxides from the Energy Production Act (1990:613) must declare their emissions once a year.

Information about the nitrogen oxides charge

The nitrogen oxides charge (NOx charge) is applied to reduce emissions of nitrogen oxides from combustion plants that produce energy. Companies operating boilers, gas turbines and stationary combustion engines for electricity and/or heat production with an annual output of at least 25 gigawatt hours are subject to the NOx charge.

The Act (1990:613) sets out who is subject to the charge and which exemptions apply.
