The European Commission insisted December 15 that the European Union should adopt new renewable energy targets by 2014 in order to enhance energy independence and eliminate CO2 emissions from the electricity sector by 2050. In an energy road map, released to meet a goal of reducing emissions to 80 to 85 percent below 1990 levels, the Commission also found that new targets beyond the 20 percent goal for 2020 were vital for investors. The road map identified five decarbonization scenarios, including high energy efficiency, particularly in the building sector; diversified energy supply; high renewable energy sources; delayed carbon capture and storage technologies; and low nuclear production.
