Abstract: Methods, systems, and computer storage media for providing ecosystem carbon emissions data using an ecosystem management engine in a carbon emissions management system. The ecosystem management engine operates as a collaborative integration platform for managing carbon emissions associated with a client and suppliers of the client based on a plurality of ecosystem management operations (e.g., data exchange and aggregation, self-service carbon emissions calculations, data validation, and carbon reduction evaluation). In operation, using an ecosystem management engine, a client communicates a request for carbon emission data from a supplier of the client. The carbon emissions data comprises product-level data of the supplier. Based on communicating the request, the client receives the carbon emissions data. One or more ecosystem management operations are executed on the carbon emissions data.
