Abstract

A system and a method for allocating energy credits is provided. The system includes circuitry that identifies a vehicle identifier associated with an electric vehicle and retrieves usage data comprising battery charging records for the electric vehicle. Each record includes a charging time-period, quantity of electrical power used, and geographic location. The circuitry determines a carbon intensity score for the electrical power consumed during each charging time-period based on the usage data. An adjusted quantity of electrical power for allocation of energy credits is determined based on the carbon intensity score and usage data. The circuitry transmits a request to an energy credit provider for allocation of energy credits against the vehicle identifier based on the adjusted quantity.
