MGM Resorts International joined the world in shutting off their lights in observance of Earth Hour

MGM Resorts International dimmed the lights at its resorts to join millions around the world in celebrating Earth Hour on Saturday, March 29.

Exterior lighting, rooftop signage, marquees and front features at the Company's major Strip resorts and Beau Rivage Resort and Casino in Biloxi, Miss. were turned off during the one-hour celebration. The worldwide movement, sponsored by the World Wildlife Fund, raises awareness for energy conservation.

Beau Rivage in Biloxi joined the movement this year, for the first time. The Company's most iconic resorts united with some of the world's other famous landmarks in the recognition of Earth Hour; the Eiffel Tower, Burj Khalifa and the Empire State Building also dimmed their lights to promote energy conservation.

"This event is an opportunity for us to join with others all over the world, to unite in a common mission and illustrate our commitment to the planet," said Cindy Ortega, Sr. Vice President and Chief Sustainability Officer. "Yet environmental responsibility is not just a one-hour observance. It is a year-round priority for MGM Resorts that reaches into every aspect of our business."

Earth Hour began in New Zealand and progressed around the world, culminating in the Pacific Time Zone of the United States.

The company has saved 420 million kilowatt hours of energy in the past five years at its resorts -- equivalent to 37,000 homes annually or 228,000 metrics tons of CO2E.
