San Francisco was the only city in the United States to make the top 10 at No. Residents there have access to 226 square feet of green space per capita and good, effective public transportation with a score of 68.4 out of 100. The city has also invested in renewable energy with 68 percent converted to it as of 2022. This is the top 10 list of green cities, according to the Reinders Corporation.
