For 2020, the EU has set an EU GHG emission reduction target of at least 20 % when compared to 1990. At European level, sectors covered by the EU Emissions Trading Scheme (EU ETS) should reduce their emissions by 21 % compared to 2005 levels and other sectors not covered by the EU ETS (non-ETS) should reduce their emissions by 10 % in relation to 2005 levels. Within the scope of the Climate and Energy Package for 2020, this emission reduction target was coupled with the establishment of EU targets of 20 % share of renewable energy in final energy consumption and an increase in energy efficiency by 20 % (EE).
