For true travel junkies, the thrill of a new place is worth whatever it takes to get there. But when it comes to your carbon footprint, all that transportation can really add up. If you just can't wrap your head around a staycation, then at least make Terrapass your new vacation essential: The carbon offset company lets you buy credits that counteract your carbon by funding renewable energy projects, like methane-gas electricity systems, wind farms, and landfill gas reduction, while transparent reports about where and how your money is spent let you follow the path of your dollars.
