Earth Day may be over, but the march to go green continues full steam ahead at Travelocity. Now, in addition to offering a huge selection of regular travel deals, the company makes it easier than ever to choose eco-friendly hotels abroad. Travelocity has formed a relationship with the Green Tourism Business Scheme and flagged hundreds of hotels in the United Kingdom with its green leaf tag:

In this era of eco-confusion, Travelocity works hard to highlight earth-friendly hotels across its site and guards against green-washing with its rigorous program. Unlike some travel sites, Travelocity does not accept “self-certified” hotels for the Green Hotel Directory. “It’s important that our eco-friendly leaf is a symbol consumers can trust,” says Alison Presley, manager of Travelocity’s Travel for Good program. “We have no way to verify that a self-certified hotel is truly sustainable. And we know our consumers depend on us to hold the line against green-washing.”

To date, Travelocity has flagged more than 1,700 hotels site-wide with the eco-friendly leaf and the company works with an elite group of certification programs. To have its hotels included in the Green Hotel Directory, a certification program must have a checklist that closely aligns with the Global Sustainable Tourism Council’s criteria. The criteria was developed by a global coalition comprised of U.N. bodies, research and academic institutions, social and environmental NGOs, certification programs, and it offers a comprehensive picture of what it means to be sustainable.

The new relationship with the Green Tourism Business Scheme has allowed the company to flag hundreds of eco-friendly hotels in the United Kingdom. The Green Tourism Business Scheme is the national sustainable tourism certification scheme for the U.K. And it is the only certification program validated by Visit Britain, through the International Centre for Responsible Tourism (ICRT).

Travelocity doesn’t just promote eco-friendly products—the company is also working hard to reduce its own footprint and to promote sustainability within the travel industry. The company’s sustainability efforts start at home with its LEED-certified Silver headquarters. And to date, Travelocity and its customers have helped The Conservation Fund plant more than 21,000 trees across three national wildlife refuges that will trap an estimated 23,000 metric tons of CO2 over the life of those forests. The company is also a founding member of the Tourism Sustainability Council, which is working toward a more sustainable future for the industry.
