Dopplr will calculate your carbon footprint

I’ve been using Dopplr for quite a while now and I just recently noticed a new tab they added to my profile page.

This new feature looks at your travel schedule retroactively and in to the future and estimates your carbon footprint.  I also noticed that when creating new trips you can select your method of travel (airplane, car, train).  I’m assuming this is to more accurately estimate your impact.  This is pretty neat since normally this type of information is pretty tricky to collect, especially when you are travelling frequently.
