21:06, 23 May 2023 Elie talk contribs created page Passenger emissions metrics (Created page with "Is it better to travel by car, bus, plane or train? A common approach would be to look at the average "carbon emissions per passenger kilometer" for each mode of transportation. But if we want a fair comparison, we have to make sure they are all calculated the same way: Two ways to calculate: * A. Assume the vehicle is packed with some arbitrary number of people.
