The U.S. Green Building Council released its LEED in Motion: Venues report, which highlights the efforts of convention centers, sports venues, performing arts centers, community centers and public assembly spaces to transform their environmental, social and economic footprint through LEED certification.

The report aims to showcase some of the most impressive green venues around the world.

“The scope and scale of the venues industry is enormous, and the leaders creating these spaces have an important role to play in reducing environmental impact,” USGBC CEO Mahesh Ramanujam said. “By incorporating green practices, venues around the world are positively impacting their triple bottom line—people, planet, profit—while inspiring others to be proactive in [social responsibility and sustainability].”

The U.S. Bureau of Labor Statistics reports that the number of conventions and events is expected to expand by 44 percent from 2010 to 2020—far outpacing the average projected growth of other industries.

Annually, the top 200 stadiums in the U.S. alone draw roughly 181 million visitors, and roughly 60 million people worldwide attend a consumer or industry tradeshow. Waste Management estimates that the NFL, MLB, NBA and NHL generate a combined 35,000 metric tons of CO2 each year from their fans’ waste. Meanwhile, the convention and tradeshow industry produces an estimated 60,000 tons of garbage each year.

Venues that incorporate LEED into their buildings tend to experience increased cost-savings, decreased annual operating costs and a higher return on investment overall. According to the 2015 Green Building Economic Impact Study, from 2015-2018, it is estimated that LEED-certified buildings in the U.S. will have saved more than $2.1 billion in combined energy, water, maintenance and waste savings.

The LEED in Motion report highlights the green strategies and savings of more than 30 LEED-certified venues across the globe, including Orlando Magic’s Amway Center, the first NBA arena to earn LEED Gold certification using the LEED Building Design + Construction: New Construction rating system, was able to save nearly a million a year, including close to $700,000 in annual energy costs alone because of LEED certification.
