Paris Agreement Calculator — measure your paris agreement impact. Evidence-based formula with reduction tips.
Home electricity: Grid emission factor varies by country — approximately 0.05–0.50 kgCO₂e/kWh depending on energy mix (renewables vs coal).
Natural gas: approximately 0.183 kgCO₂e/kWh (combustion and supply chain)
Petrol car: approximately 0.170 kgCO₂e/km (average-sized petrol car)
Short-haul flight (economy): approximately 0.255 kgCO₂e/km per passenger
Long-haul flight (economy, including radiative forcing): approximately 0.195 kgCO₂e/km per passenger
Worked example: 3,500 kWh electricity at 0.207 kgCO₂e/kWh (724 kgCO₂e) + 15,000 kWh gas (2,745 kgCO₂e) + 10,000 km car at 0.170 (1,700 kgCO₂e) + 2 long-haul return flights (20,000 km × 0.195 = 3,900 kgCO₂e) = approximately 9.1 tCO₂e before diet.
