Carbon Footprint Estimator
Estimate your annual CO2 emissions from driving, flights, diet, and electricity usage.
Estimated Annual CO2
Carbon footprint is the total greenhouse gas emissions caused by an individual, expressed in tons of CO2 equivalent per year.
Emission factors used:
- Driving: ~0.21 kg CO2 per km (average car)
- Flights: ~0.255 kg CO2 per km; average round-trip flight ≈ 4,000 km → ~1.02 tons CO2 per round trip
- Meat meals: ~3.3 kg CO2 per meal (beef average); ~1 meat meal/week ≈ 0.17 tons/year
- Electricity: ~0.42 kg CO2 per kWh (global average grid intensity)
Global averages for comparison:
- World average: ~4.7 tons CO2/year
- USA average: ~15.5 tons CO2/year
- EU average: ~6.8 tons CO2/year
- India average: ~1.9 tons CO2/year
- Paris Agreement target: ~2.0 tons CO2/year by 2050
These are rough estimates. Actual emissions depend on vehicle type, flight distance, electricity grid mix, and meat type.
