A method and system to report the environmental benefits of consumers' purchases of alternative fuels. The system tracks and stores the purchases of customers from a vendor of alternative fuels. The system calculates the environmental savings that a customer generates by using alternative fuel in place of standard fuels. Environmental savings may be calculated in terms of various metrics, including reduced carbon emissions, gasoline not consumed, or other environmental benefits. The system generates a report for each customer that details the amount of the environmental savings. The savings of two or more customers that fall within a community may be aggregated and reports generated based on the community consumption.
