The city of Phoenix is getting rid of some of its garbage trucks and earning a million dollars to do it.

Mayor Kate Gallego announced the Cleaner Trucks initiative, a project partnered with the EPA to reduce pollutants in the air.

Ten diesel garbage trucks in Phoenix are set to be permanently removed and replaced with ultra-low nitrogen oxide emission vehicles.

In addition, the city will receive $1 million as part of Diesel Emission Reduction Act grants, a program that provides diesel-emission reduction funds.

Arizona ranks 16th in air quality, according to the U.S. Air Quality Index, and Phoenix contributes a significant amount of pollution to the state. Gallego believes this project will help lower the severity.

“EPA chose Phoenix to kick off this initiative because of our aggressive sustainability goals and efforts to curb air pollution. Our residents deserve clean air and the city of Phoenix is continuing to seek out innovative opportunities and solutions,” Gallego said.

The mayor says the transportation sector is the biggest source of emissions in Phoenix, and that the new fleet of vehicles is projected to save more than 75,000 gallons of diesel fuel.
