The EPA gives the Energy Star Sustained Excellence Award to companies for leadership in reducing greenhouse gas emissions, conserving energy and creating energy efficiency practices.
EPA Administrator Lisa Jackson said this year marks the 20th anniversary of the Energy Star program.
The EPA recognized the company for reducing 5 percent of energy consumption and the company said this initiative saved $5 million.
The company reduced 55,000 metric tons of greenhouse gas emissions, equivalent to removing 11,000 vehicles per year.
More than 37,000 employees took a lifetime pledge to conserve energy and the company conducted a training program to help its 1,500 sustainability volunteers.
The company shared best practices with more than 1,100 people in industry and federal, state and local organizations.
That number includes both current and prospective Energy Star partners.
