CarbonNeutral急英翻中贈20點 - 社會議題

Expedia and Travelocity both rolled out new programs this year that let travelers buy carbon offsets. Travelers who buy offsets through Expedia and its partner TerraPass, a Web-based for-profit company in Menlo Park, Calif., for a medium or long-haul flight get a “Carbon Balanced Flyer” luggage tag. The charge is $5.99 to offset about 1,000 pounds of carbon dioxide — the amount emitted, per passenger, on a round-trip flight of up to 2,200 miles; $16.99 for a cross-country flight of up to 6,500 miles; and $29.99 for an international flight of up to 13,000 miles.
It is unclear how much impact these programs actually have on climate change — or whether they function mostly as a way for travelers to justify the amount of pollution they generate on trips. Still, many travelers see carbon offsetting as a way to help tackle global warming without having to give up that trip to the Bahamas.
