Only about 22% of Columbus’ land is made up by tree cover, which is lower than many of its national peers. Because of this, the city has come up with the Columbus Urban Forestry Plan, which in part seeks to plant millions of trees in the coming years, potentially beginning next year. You can view the plan, timeline, tree canopy statistics and neighborhood maps all the way down to a block by block level at the following link: Forestry Plan
The Transportation Climate Impact Indexmeasures 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 for the transportation climate impact index, gives an explanation on the methodology here: https://www.streetlightdata.com/2020-climate-index-methodology/
