Keeping track of your carbon footprint can be hard; you may walk or take the bus everywhere, but how much CO2 is that cross-country plane trip letting loose? UbiGreen, a new cell phone application developed by Intel and the University of Washington, senses whether you’re in a plane, train, or car to let you know exactly what your carbon footprint is.
The application uses a built-in accelerometer in your phone (like the iPhone has) to keep track of your movement. UbiGreen keeps you motivated by placing a tree on the screen of your phone that becomes leafy or barren depending on your carbon-spewing tendencies.
Unfortunately, you might have to do some manual work to find out your carbon footprint for now; the application won’t be released for another year.
