When fans come to the Los Angeles Memorial Coliseum, they’re pushing for more than a victory from the USC Trojans. They’re also part of a sustainability effort that has helped push the stadium past the “zero waste” goal line. For a stadium with a capacity of more than 75,000, that’s no small feat. Our venue now ranks as one of the most sustainable stadiums in the country. See how the stats stack up.

What is Zero Waste?

It’s when 90 percent or more of waste materials are diverted from landfills through recycling or composting. (Why not 100 percent? Because some fans bring their own non-compostable products.)

1,100 tons

Since 2015, more than 1,100 tons of Coliseum game day waste was diverted from the landfill.

During the 2021 football season, the Coliseum’s zero waste program successfully achieved an 86% waste diversion rate. Of the 74 tons of waste generated in the stadium during the season, approximately 64 tons were recovered through recycling and composting practices. A total of 24 tons of compost has been recovered, and 40 tons of material has been recycled, compared to just 10 tons of waste sent to the landfill.

In 2022, the Coliseum was the Pac-12’s Zero Waste Challenge Winner for the third time.


That’s how many custodial and sustainability staff assist with zero-waste goals at the Coliseum during games.

48 hours

It takes two full days to process waste from a game – except on weekends when the stadium hosts back-to-back events. Then there’s as little as eight hours to clean up and divert materials.

We’re #1 (and #2)

The Los Angeles Memorial Coliseum is the largest stadium in the Pac-12 and second-largest college stadium to achieve zero waste.

Our Zero Waste Initiative partners include ABM our janitorial partner, Republic Services our waste hauler, Recycling Pays our recycle hauler and Legends Hospitality, the stadium’s concessionaire, along with BASF, EcoSafe Zero Waste, USC Office of Sustainability and Waxie Sanitary Supply Co. Together, we have accelerated stadium greening.

Sustainability in Education, Research, and Operations

President Carol Folt has positioned USC as a leader in sustainable practices and has made sustainability a core part of its curriculum, fostering global citizens who will fight climate change.

Teams from across the university have established a vision, aspirations and goals for USC across five domains: Education, Research, Equity and Inclusion, Operations, and Engagement. Assignment: Earth formalizes our commitment to addressing climate change and creating a more sustainable future. It will guide our actions through 2028 and beyond and enable us to adapt to innovations and new solutions as they emerge.

As part of that effort, the Coliseum and our partners have executed a “first of it’s kind” cross-campus beverage pouring agreement and sponsorship that incorporated USC’s sustainability goals and priorities, including the elimination of single-use plastic beverage bottles.

USC Athletics has become the 5th US university to sign on to the UNFCCC’s Sports For Climate Action Framework Agreement.
