III. Governmental strategies and projects Ambitious objectives of the federal government Integrated energy and climate change programme with 30 targeted measures, 23.08.

20 III. Governmental strategies and projects Ambitious objectives of the federal government Integrated energy and climate change programme with 30 targeted measures, % reduction of greenhouse gas emissions by 2020 compared to 1990 Share of 25-30% of electricity produced from renewable energy sources by 2030 Share of 25% of electricity produced from CHP by 2020 Increase share of bio fuels to 17% by 2020 Government declaration, Reduction of electricity consumption by 11% through a massive increase of energy efficiency Increase share of renewable energy sources in the heat sector by 14% Coalition agreement between CDU, CSU and SPD, Double the energy productivity (economic performance per primary energy use) in Germany from 1990 until 2020 Meeting of the cabinet, Meseberg, 23./24. August 2007
