BeCause will collect data on hotels certified according to 33 recognised Global Sustainable Tourism Council (GTSC) standards and port this to the operator’s systems, underpinning its "eco-certified" hotel collection.

Through the new partnership, this data will be automatically updated on easyJet’s database, ensuring users have up-to-date information about a particular property’s sustainability credentials.

"We’re committed to our holidays being a force for good and making a positive impact on the environment and local communities in the destinations our customers visit,” said Matt Callaghan, easyJet holidays director of customer and operations.

“We know holidaymakers are caring more than ever about the eco-credentials of the hotels they’re choosing to stay at. So, we needed a partner to help us connect and communicate hotel sustainability data more efficiently and scale with us as we grow."

Listings on the easyJet holidays website carry an "eco-certified" tag, with the website also carrying a dedicated search function for sustainable holidays.
