Frequently Asked Questions
Why are short flights worse per km?
Takeoff/landing burn disproportionate fuel. Short-haul: ~250 g CO2/km/passenger. Long-haul: ~150 g/km. Plus radiative forcing (water vapor at altitude) ~2× the CO2 effect.
Is train always better?
In Europe + Japan: yes, dramatically (15-40 g/km). In US: depends on diesel-electric vs electric. In coal-heavy grids, EV may emit more than train. Choose train where high-speed exists.
Video calls vs flights?
1-hour video call: ~50-200g CO2 (depending on data center, screen energy). Transatlantic flight: ~1500 kg. Video call replacement: 7000-30000× lower carbon. Single biggest "skip the flight" lever.
