Abstract: A system and method for calculating real-time carbon emissions at a distribution substation level and at an individual device level is disclosed. A substation controller is provided at the utility substation that is in operable communication with one or more devices via a demand response protocol, the demand response protocol including demand response signals transferrable from the substation controller to the one or more devices and demand response signals transferrable from the one or more devices to the substation controller. A carbon emissions calculator module is embedded in the substation controller and/or the devices that is programmed to identify or receive power consumption data from respective devices and calculate carbon emissions for the respective devices based on the power consumption data. Carbon emissions data may be provided to the substation controller to provide for a determination and output of the calculated carbon emissions for each of the one more devices.
