The U.S. Postal Service saved more than $52 million in fiscal 2012 by reducing its energy, water and fuel use and by encouraging more environmentally friendly practices.
Recycling efforts allowed the Postal Service to avoid $25 million in landfill fees.
The agency also reduced spending on fuel by $12 million, facility energy use by $10 million, office supplies by $4 million, and water by $1 million.
“The Postal Service has more than 32,000 facilities, a presence in every community and one of the largest civilian fleets in the nation, so we understand how pivotal our efforts are to make a positive impact on the environment,” chief sustainability officer Thomas Day said in a news release.
Part of the savings came from the efforts of about 850 “green teams” of postal employees, the agency said.
The teams find ways to reduce waste and involve other employees in efficiency efforts at local post offices and processing centers.
