The Green Key Eco-Rating Program is a graduated rating system designed to recognize hotels, motels and resorts that are committed to improving their environmental and fiscal performance. Based on the results of a comprehensive environmental self-assessment, lodging facilities are awarded a rating from 1 to 5 Keys, 5 Keys being the highest attainable.  In support of their efforts towards becoming a cutting-edge green lodging property, members are provided with guidance on how to “unlock” opportunities for reductions in utility consumption, waste, emissions, and operating costs. Additional recommendations are also outlined for employee training, staff and customer engagement, supply chain management, community involvement and more.
