"The tax rate evolved from 1.12/t CO2 in 1990 to ?20/t CO2 in 2010. Some deviations existed: natural gas met a reduced rate, and peat was exempted in 2005-2010. In 1994-1996 a combined tax base of carbon+energy content was applied. Since 1997 the carbon tax was imposed only on traffic fuels and heating fuels; electricity was taxed per kWh and the fuels were exempted. CO2 tax revenues in 2010 were approximately 500 million (some 15% of total energy taxes). "
