Buildings play a special role in Germany’s energy transition. Accounting for up to 30% of the country total GHG emissions, this sector has one of the most ambitious targets set by the German Energy Concept and the Climate Action Plan 2050. To decrease energy demand and emissions from buildings, the policy focus lies on increasing energy efficiency and producing the remaining energy through renewable sources. Substantial additional investments are needed to reach cli-mate targets and finance the energy transition. This report aims to track how much capital was invested in climate and energy transition measures in the German building sector in 2016.
