CSR Press Release

WASHINGTON, D.C. – March 21, 2007 – Marriott International, Inc. (NYSE:MAR) announced today that it is the first lodging company to receive the 2007 ENERGY STAR Sustained Excellence Award from the U.S. Environmental Protection Agency (EPA). Marriott is being recognized in an awards ceremony tonight for its continued leadership in protecting the environment through energy management.

Since 2004, Marriott has received the Partner of the Year Award for Excellence in Energy Management, and awarded more ENERGY STAR labels (160) than any other hotel company. After much success with energy-saving programs like Linen Reuse, Group ReLamp and the replacement of showerheads, light fixtures and more, Marriott has plans to certify eighty-five additional Marriott hotels with the ENERGY STAR label this year.

"Marriott is an outstanding leader in protecting our environment through energy efficiency," said Bill Wehrum, acting assistant administrator for EPA's Office of Air and Radiation. "As one of the 2007 ENERGY STAR Sustained Excellence winners, Marriott has taken energy efficiency to new heights year after year and we all benefit."

In 2005, Marriott proactively joined the prestigious EPA's Climate Leaders as the next step in its six-year partnership with ENERGY STAR. As a Climate Leader, Marriott made a commitment to reduce greenhouse gases by 40,000 tons annually. Earlier this year, Marriott announced it has surpassed its goal in 2006 and reduced its greenhouse gases by 70,000 tons.
