7. In 2009, the EU established internal rules under the target compliance architecture - the "2020 Climate and Energy package" - that distributes the mitigation burden among the Member States and the sectors. The package is intended to combat climate change, as well as to contribute to a common energy policy after 2012. Therefore, besides reducing the level of GHG emissions by 2020 by 20 % compared to 1990, it therefore also defines headline targets in the energy field for 2020: reaching 20 % of clean, renewable energy sources in the final energy consumption, increasing energy efficiency by 20 % and, as part of the renewable energy effort, reaching, in each Member State, a 10 % share for sustainably produced biofuels and other renewable fuels in final energy consumption of the transport sector. Following controversial discussions on agricultural production dedicated to biofuels - fear of shortages and of increasing prices for food-related crops - the European Commission published, in October 2012, a proposal to limit global land conversion for biofuel production, and to raise the climate benefits of biofuels used in the EU. Accordingly, the use of food-based biofuels to meet the 10 % renewable energy target will be limited to 5%.
