For eco-friendly, guilt-free travel
TripZero.com is a travel service that will offset the carbon footprint of any trip you book at no cost to you. The company, working in partnership with Expedia, takes a commission when you book with any of the hotels in its network and uses that money to fund projects such as reforestation in Kenya and wind turbines in Indiana.
OffCents.com makes it easy to calculate just how many pounds of carbon-dioxide your flight to Maui or road trip through the Southwest will add to the atmosphere. The service gives you the option of purchasing carbon offsets by contributing to wind farms, forest protection, or methane-capture projects taking place at landfills and cattle farms.
Glooby.com, a startup, aims to let you compare prices on flights and hotels while seeing how they rank for fuel efficiency and sustainability. The service is expected to be resume late this month.
