No, the cellphone software, developed by a London start-up, doesn’t work with specialized sensors. Rather, the app tracks the user’s movement patterns via GPS, and computes whether he’s walking, driving, or flying.
Carbon Diem’s inventors claim that, by using GPS to measure the speed and pattern of movement, their algorithm can identify the mode of transport being used. It can therefore calculate the amount of carbon dioxide that a journey has emitted into the atmosphere – without any need for input from the traveller.
A pretty simple approach that apparently works… unless the owner can break the sound barrier by just running. (textually.org)
