Two years after moving to the new Busch Stadium, the St. Louis Cardinals implemented their “4 A Greener Game” sustainability plan to mitigate the environmental impacts of hosting Major League Baseball games. Since 2008, the team has shown major improvements in reducing energy use and waste generation.

For the Cardinals, the biggest impacts have come in the form of reduced energy use. By switching to compact fluorescent lights (CFLs) for nearly all the lighting throughout Busch Stadium, St. Louis has cut its energy costs by 20 percent. They have also installed more energy-efficient heating, ventilation, air conditioning, and refrigeration systems throughout the ballpark.
