Thank you for the comparison. According to this site https://co2.myclimate.org/en/portfolios?calculation_id=1057086 https://co2.myclimate.org/en/portfolios?calculation_id=10570..., London-Bangkok round trip by coach is 3.6 tons of CO2, so two r/t flights would be 7.2. The ones I know travel that much several times a year, which puts them over an order of magnitude above a suburban commuter, at least for travel costs. So compared to most of the world, who don't have cars to commute, they're multiple orders of magnitude over. Darn. I had hoped they weren't polluting so much. I hope they enjoy the environments they are helping pollute before they're gone.
