In this report Ecofys presents an approach to share the energy and climate related targets between EU Member States simultaneously. The method includes the EU’s greenhouse gas (GHG) emission reduction target (-20% or 30% in 2020), the renewable target (20% by 2020), and the energy efficiency target (20% better than reference by 2020) as well as the EU Emission Trading Scheme. The study demonstrates that greenhouse gas emissions (GHG) could be reduced by more than 30%, if the already agreed targets on renewable energy and energy efficiency are implemented and action is taken in other sectors.
