How Sports Stadiums Are Becoming More Sustainable

By Kristin Hunt

It’s tough to be sustainable when you’re housing 50,000 hungry people for three hours. Just as a concept, sports arenas are a massive drain on energy and resources. Think of all the plastics cups of beer and hot dogs in paper trays that get passed around baseball stadiums. Consider the big, blazing lights required to illuminate the football field. Add it all up and you have a pretty inefficient hub of activity, even if the fans carpooled over.

But several stadiums are working to reduce their impact. They’re adding eco-friendly design touches and implementing better waste management systems, all in an effort to make their games a little greener.

Yale Climate Connections recently reported on the the solar-powered pavilion at Chase Field, home to the Arizona Diamondbacks. The structure provides fans with some shade near the entrance, all while generating clean energy for the grid — and it isn’t the only eco-friendly feature of the sprawling stadium. Chase Field also boasts LED concourse lights, low-flow sinks, and EV charging stations. The concessions team saves the grease from their churro dogs and other treats, recycling it into a biodegradable diesel fuel.
