Green Business Certification Inc.

Green Business Certification Inc. (GBCI) is an American organization that provides third-party credentialing and verification for several rating systems relating to the built environment. It was established as the Green Building Certification Institute in January 2008 with the support of the U.S. Green Building Council to provide independent oversight of the Leadership in Energy and Environmental Design (LEED) project certification and professional credentialing processes. The organization's current name was adopted on 16 April 2015 after the organization starts to provide third-party certification for the International WELL Building Institute's evidence-based building standard WELL Building Standard on 4 April 2014, the Perfect Power Institute's PEER standard, and the Global Real Estate Sustainability Benchmark.
