Since I don’t own a car, my princiipal contribution to transport derived carbon emissions is flying. Until now, it’s been rather difficult to find a way to offset those emissions by buying credits. Terrapass has just announced a partnership with Expedia offering flyers the same sort of credits that they sell to drivers. There’s a nifty calculator which will tell you approximately how many tons of CO2 your upcoming trip will emit. It’s a simplistic system – for example, it doesn’t take into account the type of aircraft (higher occupancy planes burn less per person) – but it’s a great improvement on what’s available, and It looks like I can no longer pretend I don’t have any options.
Turns out my upcoming flight to Milwaukee in October will cost me an extra $10… that’s not too bad! (although with their tiered system I could have flown a lot further for the same price), and I don’t get a luggage tag.
