GS-33 Hotels and Lodging Properties

GS-33 establishes requirements for hotels and lodging properties. This standard does not include swimming pools, golf courses, or restaurants associated with the property.

GS-33 has three levels under which a lodging property may apply for certification: bronze, silver and gold.

Since it was first published in 1999,GS-33 has represented leadership in the industry.

Key Evaluation Categories:

  • waste minimization
  • energy conservation and management
  • management of fresh water resources and waste water management
  • pollution prevention
  • environmentally sensitive purchasing.
The standard also serves as a tool to help hotels and lodging properties consider practical steps for reducing the impacts of their operations.
