Carbon Footprint Calculator
Estimate your annual carbon footprint across flights, car, diet, and home energy.
ℹ How it works
Emission factors: flights from UK DEFRA / IPCC 2023 (short-haul 255 g CO₂e/km, long-haul 195 g CO₂e/km); car from DEFRA 2023; diet from Poore & Nemecek (Science, 2018); electricity from the EU average grid mix; natural gas combustion factor 2.04 kg CO₂e/m³. National baseline: 8.1 t CO₂e/year per capita (Umweltbundesamt UBA, 2023).
