German EU-presidentship in the first half of 2007

„Resolution of the European Parliament in march 2007:

until 2020…

• Reduction of global warming gases of a minimum of 20 %

compared to1990

• Increasing energy efficiency by 20 % compared to the trend

• A share of renewable energy in energy demand of 20 %

as a binding target
