LAS VEGAS, March 30, 2012 /PRNewswire/ -- The resorts of MGM Resorts International (NYSE: MGM) in Las Vegas will mark EARTH HOUR by turning off exterior lighting, rooftop signage, marquees, and front features from 8:30-9:30 pm Pacific Daylight Savings Time (PDST) on March 31, 2012.

"This event is designed to build awareness of the importance and impact of conservation and begins in New Zealand and progresses around the world, culminating in the Pacific Time Zone of the United States. Las Vegas is always recognized as one of the flagship cities for EARTH HOUR in the U.S.," said Cindy Ortega, Senior Vice President and Chief Sustainability Officer for MGM Resorts International.

Ortega said that environmental responsibility is a core company value for MGM Resorts that is woven into and throughout its culture and business operations.

"For our guests, environmental stewardship is becoming a key area of awareness. Our customers are becoming increasingly sophisticated in their expectations, and we are proud to be a leader in demonstrating that environmental responsibility and a superior guest experience go hand-in-hand with world-class hospitality and entertainment," Ortega said.

The company has saved 200 million kilowatt hours of energy at its properties -- equivalent to 17,400 homes -- while reducing 56,000 metric tons of carbon dioxide.

MGM Resorts also co-developed CityCenter, the largest Leadership in Energy and Environmental Design - New Construction Gold certification rating in the world for the six buildings within the CityCenter campus, including the ARIA hotel tower and convention center. LEED certification is awarded by the U.S. Green Building Council based on a project's environmental design, construction and operations. 

For the second consecutive year, MGM Resorts is listed among Newsweek Magazine's 500 most environmentally responsible companies in the United States, and also as the highest ranking company in the casino resort industry.
