Reduction of greenhouse gas emissions from the sources within the scope of the scheme by 21% compared to their 2005 levels is set for all EU Member States through a linear factor for reducing the permitted emission ceiling for the sectors under the European Trading Scheme (ETS). The main flexibility mechanism in the revised scheme is the redistribution of rights for emission allowances trading (auctioning rights), which is expected to generate substantial financial resources for investment in the improvement of energy efficiency, promotion of renewable energy and reduction of greenhouse gas emissions. For the sectors outside the scheme the differentiated emission ceilings range from -20% to +20%. Bulgaria has an individual commitment allowing it to increase the emissions by 20% compared to their 2005 level. The national objectives of the Member States in terms of share of renewables in the final energy consumption by 2020 range from 10% to 49%. Bulgaria's goal is set at 16%, including 10% share of biofuels in the final consumption of transport fuels.
