Here’s my Dopplr report for 2008. My flights were the equivalent of 5.4 Hummers, and I travel as fast as a Kangaroo. I can deploy offsets to deal with the first problem. Not sure what can be done about the second.
Update: So I missed the most troubling feature of this initially. According to Dopplr, I have a much higher velocity and much larger carbon footprint than Obama in 2008. Though he spent more nights away from home (then again, he doesn’t live in California).
