The 10 Least-Green Cities in America: 2025

WalletHub recently released their annual ranking of the 100 largest cities in the United States, ranking them based on how well they promote an environmentally friendly lifestyle. They were ranked on 28 key “green” indicators, such as greenhouse gas emissions per capita, percentage of green space, percentage of commuters who drive vehicles, bike score, farmers markets per capita, number of smart energy policies, and more by WalletHub's experts.

In this photo gallery, we are going to take a look at the 10 cities that made up the bottom of the list. Four of the 10 least-green states hail from Arizona, with southern cities making up the rest — expect for a single outlier from the east coast. As you click through the slides, keep in mind that we have listed them in descending order from most to least green based on their ranking number.
