Computer-implemented systems and methods are disclosed for facilitating generation of carbon credits to offset greenhouse gas emissions. In an embodiment, carbon emissions reduction targets for a defined time period are first received from a sponsor. A campaign is initiated for the sponsor that includes a sponsor promotion and targets selected properties and/or regions. One or more broad market simulations are then run on the targeted properties or regions to estimate an average solar energy production per property. The promotion is adjusted for each targeted property based on the property's estimated energy production compared to the average solar energy production across the targeted properties. Installation of solar energy systems on one or more of the targeted properties is then facilitated through the sponsor's campaign and promotion, and carbon credits may be provided to the sponsor that correspond to energy produced by the installed solar energy systems.
