Last spring, John Tierney channeled Nudge to propose a carbon counting lapel pin that Philip Frankenfeld later dubbed the iPed. Now it’s here. (It might have been there all along, according to some). But it’s not a lapel pin. It’s a carbon counting calculator for your cell phone.
Dubbed Carbon Diem, the software is supposed to be smart enough to determine your carbon footprint based on your movements.
(It’s developer) told me it’s just about always accurate in detecting trips taken by train or plane or subway, and was right more than two-thirds of the time in distinguishing bus trips from car trips. (It has a harder time if you’re jogging or cycling, so you have to manually classify those trips.)
The software isn’t consumer-ready yet. Its developer is shooting for early 2009, and hopes some consumers will be willing to post their footprints online (We think finding people won’t be huge a problem). Tierney opens up the floor for alternative names for this calculator. Submit yours here.
