The largest source of the emission of CO2 is the energy sector, which includes the combustion of fossil fuels such as oil, coal and natural gas. Transport is the dominant source contributing 42.0 % of the total CO2 emission. Energy industries contributes with 27.4 %. The CO2 emission (excl. LULUCF) decreased by 10.9 % from 2018 to 2019. The main reason for this large decrease is decreasing emissions from energy industries due to a decrease in the consumption of fossil fuels. Emissions from the transport sector decreased slightly driven by decreased diesel consumption. In general, CO2 emissions fluctuate significantly as a result of the electricity trade with neighbouring countries. In 2019, the actual CO2 emission (excl. LULUCF, incl. indirect CO2) was 43.0 % less than the emission in 1990.
