More than 4 million people live and work in LEED-certified buildings, according to a new report from the United States Green Building Council.

The report is part of a new series from USGBC called “LEED in Motion.” The series of reports will aim to provide a look at the green building and sustainability movement, as well as LEED certification. This first report, “LEED in Motion: People and Progress,” includes a foreword written by Platinum-level USGBC member company Hines, and highlights what is driving green building forward. The report also focuses on building occupants, LEED professionals, and USGBC members and chapters.
