BOSTON – Two Massachusetts-based companies with Rhode Island ties were recognized for their climate leadership by the U.S. Environmental Protection Agency at its Climate Leadership Conference this month.

The companies are Waltham-based defense contractor Raytheon, which has a production facility in Portsmouth, and office-supplies retailer Staples, based in Framingham.

Raytheon and Staples will receive Goal Achievement Awards for Excellence in Greenhouse Gas Management, EPA said. Both companies publicly report and verify their GHG inventories and have achieved their aggressive GHG-emissions reduction goals.

According to the agency, Raytheon set a goal of reducing total GHG emissions by 10 percent from 2008 to 2015. Raytheon achieved a 16 percent reduction by the end of 2011, meeting its goal several years ahead of schedule and exceeding its 10 percent reduction goal.

In 2003, Staples established a goal of reducing total GHG emissions by 7 percent from 2001 to 2010 under the EPA’s former Climate Leaders program. Staples exceeded its goal and cut 30 percent of its GHG, despite significant growth and acquisitions. •
