The aim of this study is to quantify the potential of heat pumps to save CO2-emissions in the EU’s building sector until 2030 and to assess related impacts on energy use, investments, energy costs and the necessary supply with refrigerants. Three scenarios are calculated, which all comprise the same very ambitious energy efficiency measures on the demand side, but different implementation shares for heat pumps on the supply side. In the scenario with the highest heat pump implementation share (“HP++”) the overall CO2-emissions for heating, cooling, hot water and auxiliary energy in buildings can be reduced by 47% from 2012 until 2030. Thomas Boermans, Ecofys explains “The EU sectoral target of 88-91% less emissions by 2050 in the built environment in Europe will not be met without the contribution of heat pumps”.
