In order to better identify hotels with environmental best practices and reduced impact to their visitors, Travelocity has recently created its new "Travel For Good" program. Travelocity is beginning to see many customers look specifically for those hotels, inns and b&b's that are working to reduce their dirty energy usage, and are embracing efficiency and renewable energy.
Travelocity also has a LEED silver HQ and are working on greening all of their travel options.
