4 A Greener Game

The Cardinals began the "4 A Greener Game" program at Busch Stadium during the 2008 season as a two month pilot program. After tremendous success, the program averages over 25 volunteers per game with numbers increasing year after year.

Since its inception, the program has diverted over 9,270 tons of waste from the stadium trash disposal and local landfills. The program's success can be partially credited to 550 conveniently placed recycling bins around the stadium, making it easy for fans to recycle when they come to a baseball game. Success is also due in large part to volunteers who collect recyclables during games, and the maintenance staff who separate additional recyclables from the trash after a game.

Help to make a difference!

The in-game volunteer Green Team is back for the 2024 season. The St. Louis Cardinals would like to invite you to be an important part of the excitement!

Once again, we are looking for friendly volunteers from local colleges, community organizations, church groups – even friends and families – to join our Green Team initiative and help collect recyclables from fans throughout each game at Busch Stadium.

The Green Team is a group of volunteers who walk down the aisles of the seating bowl in-between innings collecting recyclables from fans and promoting recycling at Busch Stadium. Volunteers are asked to arrive an hour prior to game time for a brief training session. Recycling collection begins in the 2nd inning, continues throughout the game and ends 15 minutes following the conclusion of the game.

In exchange for your services, you're able to watch the game in standing room only sections of Busch Stadium, as collections are only done in-between innings and during pitching changes so as not to disturb fans trying to watch the game.

U.S. Environmental Protection Agency (EPA) 2019 Food Recovery Challenge Regional Award
As part of EPA's Food Recovery Challenge, organizations pledge to improve their sustainable food management practices and report their results. The St. Louis Cardinals have a proven track record of promoting sustainability and making a positive impact on their community. Since 2010, they have worked with concessionaire Delaware North and Operation Food Search to keep almost 44 tons of unused food from going to the landfill. Annual food donations doubled in 2018 from 4 tons to almost 10 tons, and composting increased from 157 tons to almost 216 tons. Efforts in 2018 to reduce food waste as part of the Food Recovery Challenge resulted in the ability to provide an estimated 13,000 meals in conjunction with Operation Food Search.

Solar Power

The Cardinals partnered with Microgrid Energy, the Electrical Connection, and Sachs Electric, to bring solar energy to Busch Stadium. Fans attending the games will enjoy food, beverage and retail shops powered by 106 solar panels, producing approximately 32,000 kilowatt hours of solar energy per year.

The two solar arrays are located on the roof of the ticket building on Clark Street and atop a canopy in the left centerfield bleachers at the Ford Family Plaza. To raise awareness of solar energy, an educational kiosk providing information about the project and solar energy in general is being installed in Ford Family Plaza.

The Electrical Connection is a partnership of the International Brotherhood of Electrical Workers (IBEW) Local One and the St. Louis Chapter, National Electrical Contractors Association (NECA).

The solar panels - manufactured by Schott Solar in the U.S. - produce electricity that feeds into the stadium's electrical distribution system and mixes with the power from the grid for use throughout the stadium. There are no batteries and all the energy produced is used in the stadium. The solar energy will offset the grid power used by stadium operations, reducing electrical bills. Although the offset is a relatively small percentage of the stadium's power use, it will result in a large amount of savings over the life of the system.
