Abstract: Methods, systems, and computer storage media for providing carbon emissions data analytics recommendations using a carbon emissions data analytics engine in a carbon emissions management system. The recommendation can be associated with simulated carbon emissions optimization results data based on carbon emissions data analytics model of the carbon emissions management system. In operation, using statistical modeling, existing carbon emissions factors of standard activities are retrieved, merged and augmented. Activity data (e.g., activity data of an organization) are automatically mapped to the carbon emissions factors. Input data comprising the activity data mapped to the augmented carbon emissions factors is processed using a carbon emissions data analytics models. Processing the input data can include forecasting, scenario simulation, and scenario optimization.
