There are no CO2 taxes for these types of heating

For homeowners using certain heating systems, it will become increasingly expensive in the years to come. But those who renovate energetically can avoid additional costs for CO2 prices.

Owners of old buildings should think about an energetic renovation of their property. That is the advice of the Future Old Buildings program, which is funded by the Ministry of the Environment in Baden-Württemberg. Because rising CO2 prices could otherwise tear bigger holes in the coffers in the coming years.

As of January 1, 2022, the CO2 price will increase from 25 to 30 euros per tonne of carbon dioxide. For owners who still heat with oil or gas, this means a significant increase in operating costs. In a sample calculation, Zukunft Altbau calculated for a 150 square meter old building with an annual consumption of 3,000 liters of heating oil that from 2021 to 2025 additional costs totaling around 1,800 euros are to be calculated.

No CO2 tax for heat pumps and pellet heating systems

Because the CO2 price is to be increased step by step in the coming years, the additional costs could be much higher in the future. In a scenario in which the CO2 price increases to 275 euros per tonne by 2040, the owners of the example property would then face additional costs of 26,000 euros over the next 20 years, Zukunft Altbau has calculated.

The additional costs for gas heating during this period amounted to 21,000 euros. Anyone who uses a heat pump or pellet heating system instead is not affected by the CO2 tax.

Renovation increases the attractiveness of the old building

Frank Hettler from Zukunft Altbau therefore advises opting for renewable energies when planning a heating replacement. In addition, energy-related renovations such as the insulation of the facade reduced energy consumption and made the property more attractive for a possible sale. According to the information, up to 50 percent of the costs of such complete renovations are borne by the state.
