"Terrapass is the $50 bumper sticker," says Tom. In a period when climate change could not be more critical, Terrapass provides a way for individuals to offset their car, flight, or home carbon emissions -- and to show it on a decal and bumper sticker.

In this interview, Tom provides some interesting insight into the company, the carbon credit business, and the climate change milieu.

This past March, Terrapass became the official gift to the Academy Awards' performers and presenters, all 100,000 lbs of CO2 reductions for every Hollywood star. In addition to some Hollywood glitter, this is a sign that doing environmental good -- and showing it -- is the new chic.

Many thanks to Himanshu Agarwal and Ashish Chordia for coordinating the interview and Min Li Chan and Galen Panger for the contributions.

Stay tuned for more interesting interviews, including a whirlwind tour of Napa, California (featuring Thomas Keller of French Laundry), John Morgridge, and Vinod Khosla.
