• First energy-generation on The Strip through its 8.5 megawatt natural-gas co-generation plant, providing efficient electricity on site, reducing emissions and using "waste heat" to provide domestic hot water
• Water conservation technology and programs that will save between 30% and 43% of water within the buildings and 60% in outdoor landscaping
• First-ever fleet of stretch limos powered by clean-burning compressed natural gas (CNG)
• Nation's most technologically advanced hotel rooms with exclusive features allowing guests to "green their stay"
• Development of slot machine bases that serve as floor air-conditioning units, efficiently cooling guests from the ground up, rather than wasting energy on empty space by cooling from the ceiling
• Energy efficiency initiatives providing a savings equivalent to powering 8,800 households annually
• Creation of a large-scale recycling operation that enabled the recycling or reuse of more than 260,000 tons of construction waste, including 97% of the imploded Boardwalk Hotel

"CityCenter captures the energy and diversity of Las Vegas in one of the world's largest green urban developments," said Jim Murren, chairman and CEO of MGM MIRAGE. "Designing CityCenter with sustainable elements and practices reinforces its permanence and creates a healthier environment for our guests and residents, as well as for the 12,000 people who ultimately will work at CityCenter."

SUSTAINABILITY EFFORTS

Construction and Recycling

• The Boardwalk Hotel was imploded to make way for CityCenter. 80% of the previous structure has been recycled into the building materials or sent elsewhere for reuse. Crushed blocks and mortar were used in dust abatement on the construction site and as aggregate in concrete and asphalt; recycled whole and broken glass, and bathroom fixtures were shipped to other countries for reuse after being wrapped in Boardwalk curtains and carpets as recycled packing materials
• 95% of all construction waste that would have ended up in landfills has been recycled
• Ventilation systems have been completely sealed until installed, which protects them from the dust, smoke and harmful particles that are present on a construction site. No smoking is allowed on the site once the ventilation is sealed, which will give the buildings vastly higher indoor air quality when the facility opens
• CityCenter uses Forest Stewardship Council (FSC) wood, which ensures wood only is taken from forests with responsible management practices. Low volatile organic compound (VOC) paints are used, along with enough sustainable certified carpet to cover 140 American football fields
• Reclaimed water from Monte Carlo is used for dust control in place of precious drinking water, which has contributed to savings of 2.4 million gallons of potable water
• A concrete batch plant allowed concrete to be generated on site saving gas and energy
• Each room is carefully sealed to prevent migration of tobacco smoke ensuring freshness and comfort for each guest

• An 8.5 megawatt natural gas co-generation plant will provide efficient electricity on site (10% of overall CityCenter use), reduce emissions and utilize the waste heat from the power generation to provide all the domestic hot water necessary at CityCenter, including within its numerous pools
• Each tower has energy-efficient exterior features to help reduce the heat transfer from the sun onto the buildings, including air-brows, reflective rooftops, specially coated windows and high-performance glass
• CityCenter worked with manufacturers to invent designer water fixtures that deliver incredibly satisfying, pressurized showers while using a third less water
• Outdoor landscaping was carefully selected to provide a beautiful array of native desert plant life which is watered through a highly efficient irrigation system. The system is equipped with moisture controls to ensure watering is only done when necessary
• Marquees, signs and slot machines will be energy efficient

• CityCenter will offer sustainable options for meetings, conventions and events by incorporating environmentally responsible practices and services including sales kits constructed from recycled paper; ARIA's banquet server uniforms will be made from recycled polyester
• CityCenter employees will undergo LEED® training as part of orientation, educating them about CityCenter's green initiatives and how to do their jobs in line with the development's green focus
• Many restaurants will focus on farm-to-table ingredients, buying produce, meat and dairy direct from responsible local growers
• Spas will be committed to using organic or wild-crafted paraben-free products; the implementation of a recycling program and use of recycled paper for spa materials
• CityCenter will implement green cleaning practices within the hotels, using products that minimize concerns to human health and the environment. Additionally, the areas where chemical use occurs are negatively pressurized with separate outside exhaust and no recirculation of air
• All of CityCenter's facilities will have integrated recycling programs

• For the highest quality, environmentally sustainable travel, CityCenter has commissioned the world's first-ever fleet of CNG (compressed natural gas) stretch limos. The 26 silver, 24-foot Lincoln Town Cars are 100% dedicated to utilizing CNG. In addition to abundant U.S. natural gas reserves, CNG is one of the cleanest-burning alternative fuels available
• Natural gas used by the CNG limo fleet produces significantly lower amounts of harmful emissions such as nitrogen oxides (35-60 percent less), particulate matter (90-97 percent less), carcinogenic and toxic pollutants such as carbon monoxide (90-97 percent less) as well as the greenhouse gas carbon dioxide (25 percent less).

• Guests arriving at CityCenter via carpool or in alternative-fuel vehicles will have access to preferred parking spaces; bicycle valet services also will be provided
• The urban community offers numerous amenities within walking distance of the hotels, including restaurants, stores and entertainment. CityCenter's people mover will offer convenient transportation between Monte Carlo, Crystals and Bellagio
• CityCenter's hotels will feature the most technologically advanced guestrooms in the country, with exclusive technology that allows guests to "green their stay." With a simple setting, guests can indicate their preferred light level and room temperature, and the properties can automatically put a room into unoccupied status upon checkout, turning off the heating/cooling system, televisions, lights and any appliances
• Extensive natural light will be utilized through skylights and expansive windows at CityCenter to reduce energy use
• Many of the artists participating in CityCenter's public Fine Art Collection will use reclaimed material in their works of art. For instance, Maya Lin's silver cast of the Colorado River will incorporate the use of reclaimed silver; CityCenter's sustainability initiatives inspired her first work of art in Las Vegas. Richard Long's mud wall drawings will incorporate natural products, Nancy Rubins' will construct a gravity-defying display that includes recycled river and ocean vessels, and Isa Genzken's steel and aluminum rose will contain 75% recycled materials
