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.

The “LEED in Motion” series is available for download exclusively for USGBC members. Go here for the report.
