Frequently Asked Questions
Understanding travel carbon emissions and offsets.
How much COβ does a flight produce per kilometer?
Short-haul flights (under 1,500 km) produce approximately 195 g COβe per passenger-km due to fuel-intensive takeoff and landing phases. Medium-haul flights produce 158 g/km and long-haul flights 140 g/km. Business class seats produce roughly 3x more per passenger due to larger seat footprints.
Which transport mode has the lowest carbon emissions?
Among motorized transport, coach/long-distance buses produce the lowest emissions at 22 g COβ/km per passenger, followed by high-speed trains at 28 g COβ/km. Electric cars produce about 50 g COβ/km depending on the electricity grid carbon intensity in each country.
How much does carbon offsetting cost?
Carbon offsets through certified programs like Gold Standard ($12-25/tonne), Verra VCS ($8-20/tonne), or Plan Vivo ($15-30/tonne). A London to New York return flight produces approximately 1.8 tonnes of COβ, costing $14-54 to offset.
