Odds are pretty good that you or someone you know spends part of the day in a green-certified structure.

That was the finding from the U.S. Green Building Council’s “LEED in Motion: People and Progress” report, which says that an estimated 4.3 million people either live or work in offices or homes certified under the Leadership in Energy and Environmental Design building rating system.

And 6.2 million more people pass through such structures daily, the report said.

“LEED is a transformative force that works at the intersection of a variety of societal and economic interests, including the construction, real estate and environmental communities,” said Rick Fedrizzi, president, CEO and founding chairman of the USGBC. “The new ‘LEED in Motion’ report reflects that incredible cross-section of people — diverse in background, geography and vocation — who are working together to fulfill USGBC’s mission of a sustainably built environment within a generation.”
