Courtney Miller, NerdWallet

A solid majority, 71% of Americans, believe the country “should do whatever it takes to protect the environment,” according to a 2014 poll by the Pew Research Center.

This strong public interest in our environment extends to urban living, prompting NerdWallet’s curiosity: Even though we all know that the city we live in influences our transportation and energy choices, how do environmental impacts differ across the U.S.?

We explored the data for the nation’s 150 largest cities to shed light on the best places for those seeking a green lifestyle and a healthy environment.
