Green Action League is a Collaborative Effort
Kalin Ned — September 28, 2025The Green Action League stands out as a collaborative environmental campaign organized by a consortium of major professional sports franchises across different leagues and continents. The list includes Arsenal, Los Angeles Rams, Denver Nuggets, and Colorado Avalanche.
The Green Action League is a time-bound competition that leverages the passionate rivalries between fan bases to encourage participation in eco-friendly activities. Supported by the packaging company Ball Corporation and hosted on the Planet League platform, the program allows supporters to earn points for their chosen team by completing specific tasks such as recycling aluminum, choosing plant-based food options, or participating in community clean-ups. The Green Action League campaign is structured to crown both an individual "greenest fan" and a winning team whose collective supporters accumulate the most points.
