Climate change is a global menace, and many American states are taking initiatives to combat it. A state’s green quality score is determined by variables like environmental quality, eco-friendly behavior, and its response to climate change.

These attributes ultimately contribute to an overall score reflecting the state’s commitment to environmental sustainability and its effectiveness in implementing green practices. In essence, the
the higher the score, the greater the state’s dedication to environmental protection and sustainability.

Here are 50 states, ranked in descending order from most to least green.
