But around 2.5% of emissions come from aviation (or maybe 3% of actual warming emissions). I think that puts it in the range of 10% of transportation emissions.

Apparently personal vehicles are responsible for ~58% of transportation emissions. You're likely much more effective giving up your car than giving up flights. https://ourworldindata.org/co2-emissions-from-aviation https://ourworldindata.org/co2-emissions-from-aviation https://www.epa.gov/ghgemissions/sources-greenhouse-gas-emissions https://www.epa.gov/ghgemissions/sources-greenhouse-gas-emis... https://www.cbo.gov/publication/58861 https://www.cbo.gov/publication/58861

Yeah, remote work should really be required for jobs that can do it. That's a lot more reasonable of an immediate achievable climate action.

  Yea but airlines are government subsidized and a terrible way to shelter money, whereas commercial real estate was a great way to shelter money until the plebs decided they wanted more autonomy over their lives. I hope you understand why we have chosen to prioritize things this way.

  Hmm, I don't think 'remote work' is a climate action. Many of the people I know who work remotely live in areas where they are highly dependent on personal vehicles. Some of them moved to more remote areas where they could get bigger houses which require more heating and cooling. Given a person who lives in a smaller, well-insulated apartment in the city and has a short commute by public transit, bike or on foot, vs a person in a 2000 sqft mcmansion in the exurbs who works in their home but needs the car to go to the supermarket, who has the smaller footprint?

> Apparently personal vehicles are responsible for ~58% of transportation emissions. That's because most people in the world don't fly. If you're flying coast to coast and back once (approx 1t CO2eq), that's already a significant percentage of a typical car's yearly emissions, like 20%. Add an international flight and you're getting close to an even split. > You're likely much more effective giving up your car than giving up flights. I mean, obviously ideally you'd do both. Probably easier to significantly curtail both instead of giving it up entirely. But telling most people to give up their car is like telling them to give up a kidney or both.
