Green Key Global Eco-Rating Program V4 Resources

The Green Key Eco-Rating Program has undergone an extensive review and has been updated to version 4 (V4), which is now available to you. This update exceeds the industry’s sustainability standards and boosts bookings from eco-conscious travellers.

The new V4 update is a game-changer for sustainability in the hospitality industry, and will benefit your property greatly.

  • Many properties have improved their score when updating to V4, including several who have reached 5 keys.
  • You will not lose your certification during the process.
  • Your previous answers will be carried forward, so you will only need to revise them and answer new questions.

For more information on the transition, please see the listed resources, outlining everything you need to know about V4 of Green Key Global’s Eco-Rating program.


Green Key Global has compiled a comprehensive portfolio of documents to provide an understanding of V4 and guide properties through the assessment and audit process.

Explainer Videos

Green Key Global offers a diverse range of animated videos. These videos can help properties through the process of assessment and audit and enable them to prioritize sustainability. The animated videos are easy to follow and can be a great tool to understand and promote Green Key Global initiatives at both the property and brand level.
