What makes a city the greenest? Is it the environmental or sustainable initiatives that the city is undertaking? Or does it have more to do with characteristics of the city itself?

Career research company Zippia compared 99 cities based on their walkability, car ownership, commute length, tons of waste per person and parkland per 1,000 people. The data for the rankings came from the U.S. Census, Save on Energy and the Trust for Public Land. Zippia then ranked the 99 cities after taking all five factors equally into account to determine the greenest cities in America.

We’ve included the top 10 cities here. Is yours on the list?
