Carbon Hero is a cool project still in development, aiming to determine what modes of transportation you’re using via GPS and calculating the associated carbon usage. Although tested with GPS on Nokia smartphones already, the final product will be using a new European positioning system called Gallileo, which claims to be accurate to under a metre. BlackBerry support is underway, but Gallileo won’t be online until 2013, so it could still be awhile until we see a release. The big thing with Carbon Hero is that it will be largely automated, with as little user input as possible and simply providing the information about how much you’re ruining the planet. Talk about low maintenance guilt-tripping.
