39. Fort Worth, TX

Air is everywhere in Fort Worth’s green agenda. The city is teaming up with neighboring Dallas to alleviate air quality problems in a plan that proposes a 55 percent reduction in pollution from 1999 levels. The plan is an ambitious one, with a call to reduce ozone forming pollutants by nearly 90 tons per day. As part of the Texas Clean School Bus Program, over 230 Fort Worth Independent School District busses have been revamped to reduce emissions. The focus on air doesn’t mean that Fort Worth is forgetting about its water—the city is also working to reduce water consumption by converting recreational fields to turf, saving an estimated 11.5 million gallons of water per year. If that amount sounds staggering, try this one: Fort Worth’s water reuse program saves over three billion gallons of water each year – and the city is looking to expand it.
