Online travel services Travelocity and Expedia both have begun allowing customers to purchase carbon offsets when they buy travel. Airline travel currently accounts for about 13% of U.S.-transportation-based emissions of carbon dioxide.
Travelocity is working in conjunction with the Go Zero program of The Conservation Fund, and offers carbon offsets to anyone buying a vacation package (flight + hotel + rental car). Expedia is working with TerraPass (earlier post) and offers the offsets to anyone purchase a plane ticket.
