These efforts make MGM National Harbor a destination as a premier environmentally sustainable urban community. The 3,544,000 square foot (includes 2,220,000 sf of covered/below grade parking), multi-use development incorporates a variety of environmentally minded practices and sustainability elements, including: energy efficient systems, occupancy comfort and wellness minded material selection, preferred parking spaces for electric and high-efficiency vehicles, and emphasis on a number of technologies and innovations to manage water. With properties hosting millions of visitors every year, MGM Resorts International recognizes its responsibility to positively influence its guests to embrace environmental stewardship. The MGM National Harbor project integrates environmentally responsible practices, effectively lowering the carbon footprint of its operations, including our resorts, restaurants, retail spaces, meetings and conventions. MGM National Harbor features a 23-story, 308-room luxury hotel with amenities including: fine dining from local and celebrity chefs, world-class entertainment, luxury retail shops, and a 3,000-seat theater and a resort spa.
