CO2 Pricing in the Building Sector and Necessary Additional Instruments

CO2 pricing provides incentives for investments in climate-friendly heating technologies and energy-efficient renovation. But a tax on greenhouse gases or an emission trading system alone will hardly be enough to make them economically attractive. Additional policy instruments are needed to do justice to the special features of the building sector. These are the key findings of a study conducted jointly by the Institute of Energy Economics at the University of Cologne (EWI) and the Institute for Public Economics at the University of Cologne (FiFo) on behalf of the Zentraler Immobilien Ausschuss e.V. (German Property Federation) (ZIA).

The Climate Protection Programme 2030 and its impacts
The calculations of the EWI on the burden and relief of households through the “Klimaschutzprogramm 2030” show the effects of the CO2 price, the commuter allowance, and the EEG compensation. For example, a 3-person family with one commuter in an unrenovated single-family-house with an old oil heating system will have additional costs of 201 euros in 2025. In contrast, a high-income family with two commuters in a partially renovated single-family house will have higher costs of 108 euros in 2025 due to the climate protection programme. For a couple in an unrenovated apartment with a gas heating system without commuters, the effects of CO2 pricing and EEG compensation almost cancel each other out.
