Are gasoline powered commuter vehicles really at the center of the climate problem? I was under the impression that most emissions came from the commercial and military sectors.

The thing is there isn’t really any “center” of the climate problem. It’s a billion different things. Just about every part of the global economy is at least a little bit underwritten by fossil fuels.

Yeah the commercial and military sectors contribute a lot, but not overwhelmingly so, and also “commercial” isn’t even that useful of a category since it groups a lot of different things together (it could mean production of anything from medical equipment to children’s toys).

This has a good chart showing how diffuse it all is: https://www.vox.com/2014/10/22/18093114/where-do-greenhouse-gas-emissions-come-from
