Patent ID: 8682759

Claim:
A non-transitory tangible computer readable storage medium having stored thereon a computer program for implementing a system for determining emissions offset credits associated with the consumption of environmentally cleaner non-petroleum fuels in an environmentally cleaner vehicle designed to obtain all of its automotive power through consumption of a petroleum fuel and which has been retrofitted to obtain at least a portion of its automotive power through consumption of at least one of the environmentally cleaner non-petroleum fuels, the computer program comprising a set of instructions which, when executed by a computer, cause the computer to perform a method comprising the steps of: obtaining an identifier to associate a refueling action with a user of the environmentally cleaner vehicle or with the environmentally cleaner vehicle; and accessing a database containing data entries to record creation of emissions offset credits for the user of the environmentally cleaner vehicle or for the environmentally cleaner vehicle based on the identifier, the emissions offset credits being calculated by comparing an amount of petroleum based fuel used to provide automotive power to the environmentally cleaner vehicle after being retrofitted to obtain at least a portion of the automotive power through consumption of the at least one of the environmentally cleaner non-petroleum fuels with an estimated amount of petroleum based fuel that would have been required to provide equivalent automotive power to the environmentally cleaner vehicle in its original designed condition.
