How the calculator works
Each fuel releases a fixed amount of CO2 when burned. The calculator multiplies your consumption by that emission factor, then by the CO2 price per tonne, and adds 19% VAT because suppliers build the CO2 price into the energy price. All factors and sources are listed on the methodology page.
What is the CO2 price in 2026 and 2027?
Since 2026, Germany's national CO2 price forms within a corridor of €55 to €65 per tonne. Because the EU emissions trading system for buildings and road transport (ETS2) was postponed by a year, the German cabinet decided in August 2026 to keep the same corridor for 2027. The calculator shows a range for both years.
What changes from 2028?
From 2028 the EU-wide ETS2 is set to replace Germany's national system. The price will then be set by the market across the EU, with mechanisms to limit sharp rises. Nobody can predict it reliably, so you can pick one of three scenarios. They are assumptions, not forecasts.
Renting? Your landlord pays part of it
In rented homes, Germany splits the CO2 cost between tenant and landlord based on the building's energy performance. Use the tenant and landlord CO2 cost calculator to see your split.
Common questions
Is the CO2 price already in my gas bill?
Yes. Suppliers include it in the unit price, even if it isn't shown as a separate line.
Why is there no CO2 price on pellets?
Wood and pellets count as biogenic fuels and are exempt from both the national CO2 price and ETS2.
