Expedia teamed up with the carbon offset experts at Terrapass. The program allows a traveler to pay his/her offset fee anytime before checking out. The money goes to a host of domestic clean energy projects such as wind farms and methane capture plants as well as the retirement of carbon offsets on the Chicago Climate Exchange.
Travelocity's program, dubbed GoZero, is limited to travelers who buy vacation packages. Those customers will have the option of sending a tax-deductible donation to The Conservation Fund, a nonprofit organization that plants trees.
Travelocity users who opt for the carbon offset program can expect to pay $10 for an average one-night trip which includes air travel, a hotel room and a rental car for one person. $40 would offset air travel, a 4-night hotel stay and a rental car for 4 people. Expedia's carbon offsets start at $5.99 for a 2,200 mile flight while 13,000 miles would cost you $29.99.
