Pittsburgh, June 3, 2025 — 3R Sustainability is proud to have supported the Green Sports Alliance (Alliance) in achieving ISO 20121 certification—the international standard for sustainable event management.
Green Sports Alliance is a major driver of environmental and social responsibility in the global sports industry and is the host of the annual Green Sports Alliance Summit—one of the largest gatherings that unites the sports and entertainment community around sustainability. The Alliance’s ISO 20121 certification is a testament to its commitment to sustainability. By achieving this internationally recognized standard, Green Sport Alliance is leading by example and showing the value of embedding sustainable practices into event management.
“Green Sports Alliance didn’t pursue ISO 20121 just to check a box—they did it to lead by example,” said Gina MacIlwraith, Director, Management Systems and Assurance, 3R Sustainability. “At 3R, we’re proud to partner with organizations like Green Sports Alliance that share our belief in walking the talk. This sustainable event management certification not only strengthens the Alliance’s credibility, but it also equips them to help others across the sports and entertainment industry realize the value of sustainability and drive meaningful change.”
3R is honored to have supported the Alliance throughout this journey—mentoring a team of dedicated undergraduate students from the University of Michigan who also participated in this project—by providing expertise and strategic guidance to help them achieve their goals. The certification process included:
- A comprehensive gap assessment
- A customized roadmap to certification
- Implementation support
- Preparation and guidance throughout the auditing process
We also want to recognize RoyalCert International Registrars for their quality and fair auditing service during the certification process.
As a Green Sports Alliance Play to Zero member, 3R is committed to supporting the sports and entertainment industry in its pursuit of a more sustainable future. This collaboration reflects a shared mission to help venues, leagues, teams, universities, and events drive positive change through sustainable event systems. Working at the intersection of sustainability, sports, and entertainment, 3R offers services that help Alliance members realize the value of sustainability across their organizations and assets. 3R is also a sponsor of the upcoming Green Sports Alliance Summit, which will be held in Miami, FL, June 10–12.
