If politicians left the heating transition exclusively to the market, heating costs for households would in all likelihood rise dramatically. This is the conclusion of a new joint study by the Öko-Institut and the „Paritätischer Gesamtverband.“ Their analysis is based on the assumption that the Building Energy Act (GEG) would be overturned and a carbon price alone would be used to make heating climate-friendly. The key result: „It would require a CO2 price of 524 euros for CO2 emissions to fall as much as they are expected to do by 2030 as a result of the Heating Act.“
