In celebration of Earth Day, Johnson Controls, Milwaukee, a provider of solutions that increase energy efficiency in buildings, released its Top Earth Day Champions list to highlight organizations saving the carbon equivalent of 45,000 acres of pine forests through energy efficiency and renewable energy projects at their facilities. That’s the interesting part — which organizations and vertical markets made the list. Schools, a laboratory, a United States Army facility, even a waste water treatment plant make the list.

Carbon emissions from building energy use are predicted to grow faster than any other sector in the next 25 years, according to the U.S. Green Building Council, making building efficiency critically important for the protection of the environment. Here are Johnson Controls’ 2012 Top Earth Day Champions and the equivalent amount of carbon dioxide emissions they are saving annually through projects with Johnson Controls.
