LAS VEGAS, Jan. 29, 2013 /PRNewswire/ -- Fifteen resorts operated by MGM
Resorts International (NYSE: MGM) have achieved the prestigious Green Key
rating for environmental conservation from the largest sustainable operations
certification body in the world. The accomplishment peaks MGM Resorts'
previous achievement of 12 properties designated with "Green Key" honors.

Since a previous assessment in 2010, Bellagio has risen in rank from "4 Green
Keys" to "5 Green Keys" by updating energy efficient equipment and initiating
new maintenance programs. Bellagio has also implemented new operating
policies and procedures, and enhanced its recycling efforts and sustainable
food and beverage practices. Circus Circus Las Vegas rose from "3 Green Keys"
to "4 Green Keys" in the most recent assessment.

Three other properties - ARIA Resort & Casino, Vdara Hotel & Spa and Mandalay
Bay Resort have maintained their "5 Green Keys" designation since 2010. Less
than two percent of all current hotels that are rated have reached the elite
"5 Keys" category.

MGM Resorts properties that achieved a "4 Green Keys" rating during the recent
assessment include: Luxor, Excalibur, New York-New York, Monte Carlo, The
Mirage, Circus Circus Las Vegas, MGM Grand Las Vegas, The Signature at MGM
Grand, MGM Grand Detroit, Beau Rivage in Biloxi, Miss. and Gold Strike in
Tunica, Miss.

This is the first-ever Green Key assessment conducted at The Signature at MGM
Grand, Beau Rivage in Biloxi, Miss., and Gold Strike in Tunica, Miss.
