The results show that within U.S. cities, economic circumstances and climate change measures are correlated: cities like Baton Rogue, Louisiana, and Detroit, Michigan, which scored the lowest on the index, had high levels of relative poverty and unemployment as well as higher emission rates.
- Coastal regions consistently rank the highest overall, and six regions in the Top 10 list are located on the West Coast. The San Jose-Sunnyvale-Santa Clara metro region is at the top of the Index, with a score of 61.04. San Jose, which is the tenth most populous city in the U.S., has pioneered environmental sustainability in part by partnering with its robust tech sector and scored the highest ranking of cities creating partnerships to reach their goals.
- Poverty, malnutrition, and obesity are endemic problems in cities across the country. The average percent of the population living below the national poverty line 15.6 percent, or 33.28 million people, but the southwestern states are seeing the worst rates of poverty. However, this does not necessarily correlate with personal income, as cities on the West Coast (aside from San Francisco and San Jose) tended to score the lowest.
- Rust Belt states have the worst carbon footprints in the U.S., but no cities are cutting carbon emissions enough to meet the 2 degree Celsius temperature change goal set under the Paris agreement. Annual carbon emissions per capita in the U.S. are around 17 tons, and even the U.S. cities which scored the best in this category scored below 40. The analysis attributes Rust Belt cities’ performance to the region’s high rates of vehicle ownership and a lack of serviceable public transportation.
