1. A method for remotely determining vehicle driver performance for a specific vehicle and driver using acceleration measurements and estimated carbon emission patterns for a plurality of vehicle behaviors and conditions derived from said acceleration measurements, said specific vehicle being one of a defined vehicle type, the method comprising:

  • developing a carbon emission pattern prediction model for the vehicle type comprising;

    collecting data over time from one or more carbon emission sensors andone or more accelerometers from a plurality of vehicles of said vehicle type driven in a variety of manners and in a variety of conditions,observing patterns in the carbon emission data and the acceleration datafor each of the plurality of vehicles driven and for each of the manners and conditions driven,developing statistical comparisons between the observed carbon emissions patterns and the associated acceleration patterns, andstoring representative patterns and statistical comparisons in a remote computer memory along with identifying information for the vehicle type, driving manner and conditions for each pattern;

    identifying specific vehicle and driver carbon emission patterns for the specific vehicle and driver by;

    collecting acceleration and corresponding carbon emissions data over time for the specific vehicle while operated by the driver from one or more on-board carbon emission sensors and accelerometers;

    developing specific vehicle and driver statistical comparisons between collected acceleration and corresponding carbon emissions data for the specific vehicle and driver, andstoring, as specific vehicle and driver acceleration patterns, the acceleration and corresponding carbon emissions data, and said specific vehicle and driver statistical comparisons in a specific vehicle on-board computer memory;

    subsequent to said identifying and on-board the specific vehicle, calculating carbon emissions for the specific vehicle and driver by;

    measuring acceleration for the specific vehicle with one or more on-board accelerometers while operated by the driver,comparing the acceleration measurements for the specific vehicle with the stored specific vehicle and driver acceleration patterns accessed from the on-board computer memory, andupon finding one or more matching acceleration patterns, querying the on-board computer memory to return one or more corresponding carbon emissions;

    transmitting the returned corresponding carbon emissions, along with identifying information for the specific vehicle and driver, to a remote user;

    comparing, at a location remote from the specific vehicle, the transmitted carbon emissions with said representative patterns and statistical comparisons stored in the remote computer memory for the vehicle type corresponding the transmitted specific vehicle identifying information; and

    assigning the driving manner for each representative pattern matching the transmitted carbon emissions as the driver performance for the specific driver corresponding to the driver identifying information.
