FAQ
Frequently Asked Questions
What is the average CO2 footprint per person in Germany?
The average German CO2 footprint is about 10-11 tonnes per year. The global average is about 4.7 tonnes. The climate-compatible target is about 1 tonne per person per year.
How can I reduce my CO2 footprint?
The biggest levers are reducing air travel, driving less or switching to electric, eating less meat, reducing energy consumption at home, and choosing green electricity.
Which electricity prices are baked into the calculation?
An average household electricity price of about 36 ct/kWh is used (Germany 2026). Actual prices vary by provider and tariff — the calculator allows you to enter your own value.

Key Data and Facts
Average CO2 footprint Germany: approx. 10.8 t/year. Climate target: under 2 t/person. Largest items: heating, car, flying and diet.
Step-by-Step Guide
How to calculate your CO2 footprint step by step: 1. Housing: Enter your heating energy consumption (kWh of gas, oil, district heating). Emission factors: natural gas approx. 0.20 kg CO2/kWh, heating oil approx. 0.27 kg/kWh, district heating approx. 0.18 kg/kWh. Electricity: depending on the mix, approx. 0.38 kg CO2/kWh (Germany 2024). 2. Mobility: Enter your annual mileage (km) and consumption. Petrol car: approx. 2.37 kg CO2/litre, diesel: approx. 2.65 kg/litre. Air travel: short haul approx. 200 g CO2/km, long haul approx. 300-400 g/km (incl. RFI factor). 3. Diet: Mixed diet approx. 1.7 t CO2/year, vegetarian approx. 1.2 t, vegan approx. 0.8 t. 4. Consumption: Clothing, electronics, services -- on average approx. 2-3 t CO2/year. 5. Compare the result: German average approx. 10.8 t CO2/year. Climate target: below 2 t per person.
Calculation Example
Example person: gas heating 15,000 kWh (3.0 t) + electricity 2,500 kWh (0.95 t) + car 12,000 km on 7 l/100 km petrol (1.99 t) + 1 flight (0.8 t) + mixed diet (1.7 t) + consumption (2.5 t) = approx. 10.9 t CO2/year.
