Among all the add-ons that Travelocity.com pushes during the booking process is a new program that offers to neutralize the environmental impact of customer trips by planting trees, which absorb carbon dioxide, the primary greenhouse gas, The New York Times reports. Each customer pays a certain sum, anywhere from $5 to $30, depending on the length of the trip and the form of transportation. This fee covers the planting of enough trees, as estimated by the calculations of the nonprofit Conservation Fund, the group running the program, to offset the carbon emissions that could be attributed to the traveler's trip.
