The Green Parking Council (GPC), a nonprofit organization and affiliate of the International Parking Institute provided leadership and oversight for the green conversion of parking facilities to sustainable, environmentally responsible assets. GPC expanded green parking practices and promoted sustainable urban mobility through its Certified Green Garage rating system. The Certified Green Garage rating system was acquired by the United States Green Building Council (USGBC) and is administered by the Green Business Certification Inc. (GBCI), the certification arm of the USGBC. Rebranded and launched as the Parksmart rating system, Parksmart is now aligned with the full suite of LEED programs under the USGBC organization.
