The numbers behind this
- Short return flight: 250 kg CO2e
- Medium return flight: 600 kg CO2e
- Long haul return flight: 1800 kg CO2e
- Car: 0.17 kg CO2e per km (average petrol car)
- Electricity: 0.25 kg CO2e per kWh (EU grid average)
- Natural gas: 1.9 kg CO2e per m3
- Food: 2500 kg (meat every day), 1700 kg (average), 1100 kg (plant based) per year
Factors are rounded averages based on published figures from the UK DEFRA conversion factors, the European Environment Agency and peer reviewed diet studies. Your real footprint depends on your car, your energy supplier and where you live, so treat this as an estimate rather than an audit.
