MILWAUKEE (AP) -- The home of the Milwaukee Brewers is being honored for going green.

Miller Park has been certified as a LEED building. The L-E-E-D stands for Leadership in Energy and Environmental Design and provides a set of international standards for energy-efficient and environmentally friendly methods and materials.

It's the first stadium with a retractable roof with the designation and third in Major League Baseball. The other two stadiums are AT&T Park in San Francisco and Target Field in Minneapolis.

The Brewers made improvements to the stadium's heating, ventilation, air conditioning, plumbing, electrical and power systems.

Team officials say the changes resulted in reducing more than 1,100 metric tons of carbon dioxide emissions annually, the equivalent to taking 220 cars off the road each year.
