How much carbon are you responsible for pumping into the atmosphere on a given day? You could rely on broad statistics from any number of environmental groups, you could fail to care altogether, or you could actually get yourself a close estimate with Clear Standards’ new Carbon Tracker app for the iPhone, released on Thursday.
Using the phone’s built-in GPS capability, Carbon Tracker logs your movements throughout the day, automatically generating a list of trips. Assigning a vehicle type to them allows the software to calculate a carbon footprint automatically. You can also set emissions goals for different periods of time to try to monitor, and reduce, your output as you go.
