Fact Sheet: The Swedish NOX emissions tax
Soil acidification and water eutrophication caused partly by emissions of NOX from combustion processes in transport, industry and power plants has been a major problem in Sweden since the 1980s. The NOx tax and reimbursement system were introduced in 1992 with the intent of reducing emissions of NOX from energy generation in combustion plants and combined heat and power plants. The NOX tax is an economic instrument that aims to give incentive for operators to reduce emissions and invest in advanced combustion and pollution abatement technologies.
The overall purpose is to achieve environmental objectives for acidification, eutrophication and fresh air. From the time the tax was introduced in 1992, NOX emissions from such plants was continuously reduced proportional to the energy produced. Since 1991, emissions per unit of energy produced have decreased from 0,4 kg/GWh to 0,18 kg/GWh.
