What Is the Eco-Rating Program?
The Green Key Global Eco-Rating Program evaluates hotel sustainability performance across five core areas:
- Corporate Environmental Management
- Housekeeping
- Food & Beverage Operations
- Conference & Meeting Facilities
- Engineering
Hotels complete a self-assessment questionnaire followed by a virtual or in-person audit. Based on your results, you’ll receive a 1 to 5 Key rating and a detailed action plan for continued improvement.
Why Certification Matters
Today’s guests, corporate clients, and travel booking platforms may expect hotels to operate sustainably. Green Key Global’s third-party verified certification helps hotels meet those expectations while gaining operational, reputational, and financial benefits.
When your property earns Eco-Rating certification, it can help:
- Generate additional bookings by getting automatically listed on Online Travel Agencies (OTAs) like Booking.com, Google, and Expedia
- Improve cost savings by lowering energy, water, and waste costs
- Boost credibility in corporate travel RFPs and win more business
- Qualify for green financing, sustainability grants, and incentives
