Merck Receives 2011 ENERGY STAR® Sustained Excellence Award From U.S. Environmental Protection Agency (EPA)

WHITEHOUSE STATION, N.J., - Merck (NYSE: MRK), known as MSD outside the U.S. and Canada, announced today that it has received a 2011 ENERGY STAR Sustained Excellence Award from the U.S. Environmental Protection Agency (EPA) for its continued efforts to protect the environment through energy efficiency.

Merck has been an ENERGY STAR partner since 2004 and recognized by the EPA for six consecutive years - twice as Partner of the Year and now a fourth time for Sustained Excellence. The 2011 ENERGY STAR Sustained Excellence Award recognizes the accomplishments of Merck’s energy management program, including ENERGY STAR designations for six manufacturing sites and the two corporate office buildings at the company’s headquarters campus. The company has established an aggressive greenhouse gas reduction goal of 10 percent by 2015 from a 2009 baseline.

"Managing energy well is consistent with Merck’s philosophy of being a responsible company" said Rodney Freeman, Merck’s vice president, Global Facilities Management. "We are using ’greener’ sources of energy and monitoring greenhouse gas emissions. Our partnership with ENERGY STAR helps us focus on our main goal of reducing energy consumption. We believe the greenest Kilowatt is the one not used"

"Merck has earned EPA’s highest ENERGY STAR award - the 2011 Sustained Excellence Award" said Elizabeth Craig, acting director, EPA Office of Atmospheric Programs. "Merck’s long-term leadership and commitment to energy efficiency demonstrates the types of accomplishments that we can all achieve in reducing greenhouse gas emissions and protecting our global environment. We look forward to their continued partnership and leadership"

Three Merck manufacturing sites - Stonewall, Va., Wilson, N.C., and Barceloneta, Puerto Rico - received the ENERGY STAR Challenge for Industry for reducing energy use by more than 10 percent in the previous three years. Three additional manufacturing sites - Cleveland, Tenn., Elkhorn, Neb., and Las Piedras, Puerto Rico - earned an ENERGY STAR award for ranking in the top 25 percent of pharmaceutical plant energy performance nationwide. Merck’s headquarters in Whitehouse Station, N.J., qualified for the ENERGY STAR label for the third time.

Merck will be recognized at an awards ceremony in Washington, D.C., on April 12, 2011. Corporate responsibility is embedded within Merck’s global business strategy to ensure improvement in the health and well-being of society while also delivering value to the company’s shareholders. Operating in an environmentally sustainable fashion is one of four priority areas of corporate responsibility at Merck.
