This report provides options for how to achieve a 30% reduction in greenhouse gas emissions, in the EU, from 1990 to 2020. The EU has agreed a set of goals and related instruments for 2020. The most significant objectives are the 20% or 30% reduction of greenhouse gases, the 20% improvement of energy efficiency and the 20% of renewable energy use by 2020. The stringency of the instruments used to reach these goals, must be set carefully to ensure overall consistency. Particularly after the economic crisis of 2008/2009, the Climate and Energy Package has to be tuned again to be fully consistent, e.g. fast take up of renewable energy and fewer emissions due to the recession may cause an over-allocation in the EU-ETS.
