The Leadership in Energy and Environmental Design (LEED) Certification program, which was developed by the US Green Building Council (USGBC), has become the standard against which most other green building models are measured by and is used by architects, facility managers, real estate professionals, construction managers, lenders, government officials, and interior designers to develop sustainable building designs. Today, the LEED Certification rating system is used in the US as well as Canada, Brazil, India, and Mexico.
LEED green building standards are developed through a committee-run, consensus-based process.

The LEED Certification system is available for a wide variety of building types, including:
