Thanks for providing this perspective!

I think it would be super interesting to look at CO2 emission per capita broken down by states (i.e. perhaps states along the coasts would show a very different picture than less populated states).

309 people per mi2 (France) vs 421 for the NY state.

even better, by zipcode: https://coolclimate.org/maps

its astonishing how the difference between "live in a city" and "live in the suburbs outside a city" is more than 3:1

Without controlling for income, it's hard to draw good conclusions here. Looking at the area I am familiar with (Boston and its inner suburbs), CO2 emissions seem to correlate pretty well with income for areas which are a similar distance from downtown Boston and similarly dense/built-up.

Of course there's the open question of whether something like Brookline or even more so Cambridge or Somerville count as "suburbs outside a city".

Also from the area, I get the sense that the Boston area is generally increasing in carbon efficiency (at least pre covid). There simply isn't space to build more/bigger highways into Boston, the only feasible way to expand capacity is increasing density and more transit/biking.
