In 2015, the energy sector was responsible for 87.93% of Estonia's greenhouse gas emissions. The majority of energy emissions are due to extensive use of fossil fuels in the production of heat and electricity. In October 2017, the Estonian Government adopted the Estonian Energy Development Plan until 2030 that aims to reduce greenhouse gas emissions in the energy sector by 70% compared to 1990 levels, while also increasing the share of renewable energy sources in final energy consumption to 50%.
