Many event clients hold sustainability as a strategic corporate priority and look to champion their commitment in their events. At MGM Resorts, we are proud of the unique environmental attributes of our large event venues, including the Mandalay Bay Conference Center, which features America's largest contiguous rooftop solar array. We optimize energy and water use, increase our use of renewable electricity and adopt extensive materials and waste reduction programs into our venues, recognizing that a venue’s environmental programs and practices drive much of its carbon footprint.

Our approach to sustainable events aims to save water and energy, reduce materials and waste and engage the community. For this, we focus on four areas: venue and space, décor and signage, food and beverage, and outreach and education. To assist clients in improving the environmental efficiency of their events, MGM Resorts has designed a custom deck of playing cards featuring 52 sustainable event ideas. The ideas also support one or more of the United Nations Sustainable Development Goals (UN SDGS), which are also visually highlighted on the cards, as well as an assessment of the likely cost impact. The ideas on the cards combat the common misconception that environmental and societal benefits from events are cost prohibitive.
