The legal requirements of the Heating Costs Ordinance have so far stipulated that all costs of the CO2 price end up with the consumer, i.e. with the tenant; this encourages tenants to heat sparingly, but does not encourage landlords to make buildings more energy-efficient. That is why countermeasures are now being taken with a new law, the cumbersome Carbon Dioxide Cost Allocation Act (CO2KostAufG).
In the future, the CO2 price will be based on a Stage model between tenants and landlords divided up. The less climate-friendly the house is, the higher the landlord’s share of the costs. A price currently applies 30 euros per tonne of CO2, which is emitted when heating and fuels are burned. He is said to be progressively up to 55 euros increase in 2025.
For non-residential buildings, a flat-rate 50-50 solution will be introduced, with tenants and landlords sharing the costs. In the case of residential buildings, the landlord must Calculate carbon emissions per square meter of living space and year. This value is used to distribute the costs, as shown in the table.
In contrast to the draft law, there seems to have been a change over the last few meters. In the case of particularly poor values, the landlord should 95 percent of the cost have to shoulder.
