Understanding Travel Emissions
Transportation is one of the largest contributors to global CO2 emissions. Choosing the right mode of transport can significantly reduce your carbon footprint. Our calculator uses average emission factors to help you make informed decisions.
Emission Factors Used
- Train: ~0.03 kg CO2 per km (Electric/Diesel mix)
- Car (Petrol): ~0.18 kg CO2 per km (Single occupancy)
- Flight: ~0.25 kg CO2 per km (Short-haul average)
We use average emission factors: Train (0.03 kg/km), Car (0.18 kg/km), and Flight (0.25 kg/km). Values may vary based on specific vehicle, occupancy, and fuel type.
Trains are generally the most eco-friendly option, producing significantly less CO2 per kilometer compared to cars and flights, especially over medium distances.
Planes emit CO2 at high altitudes where it has a stronger warming effect. Additionally, short-haul flights are less fuel-efficient per kilometer than cars.
