Carbon Miles helps create a world in which individuals, families and communities are empowered to take ownership of their carbon footprint. By utilizing open vehicle data, Carbon Miles calculates a user's vehicle related CO2 emissions. These emissions are communicated to the user in the form of pounds of CO2 as well as the tree years needed to absorb the CO2 emitted. While the primary function of this app is to capture and communicate CO2 data for the most recent trip, Carbon Miles also develops a profile for the user that captures the user's monthly, yearly and lifetime vehicle related CO2 emissions. Finally, Carbon Miles makes tangible the difference in CO2 emissions given alternative forms of vehicle use.
