Estimate your trip's carbon footprint and offset with trees
distance = great-circle distance between airports (shortest path on Earth)1.1 = detour factor (adds 10% for indirect routing, holding patterns, ATC paths)Domestic (<500 km): 0.255 kg/kmShort-haul (500–3,700 km): 0.156 kg/kmLong-haul (>3,700 km): 0.150 kg/km30.9 kg CO₂e per night = estimated average derived from Cornell Hotel Sustainability
Benchmark data and related hospitality emission studies.0.089 kg CO₂e per passenger-km = average emissions for shared vehicle transport (vans,
minibuses, tour buses).Car emissions are calculated by multiplying the total distance traveled (km) by an emission factor of 0.171 kg CO₂e per km. This factor represents the average emissions of a standard passenger vehicle including fuel combustion and associated greenhouse gases.
