This link https://3yemud1nnmpw4b6m8m3py1iy-wpengine.netdna-ssl.com/wp-content/uploads/Climate-Index-Top100-FullList.pdf measures how the 100 largest US metros rank in terms of climate impact from everything from walkability to vehicles miles.
Ohio cities don’t rank highly, unfortunately. Columbus clocks in at #85, with its worst ranking coming from how much its residents drive. Columbus’ bus system only goes so far, and without any other form of transit, much of the area is completely car-dependent.
Streetlight, which makes the rankings, gives an explanation on the methodology here: https://www.streetlightdata.com/2020-climate-index-methodology/
