Abstract: A method and system for reducing carbon footprint. The process includes the step of receiving a plurality of carbon offset products available for purchase, maintaining an inventory of the plurality of carbon offset products. The process further include the step of displaying the plurality of carbon offset products along with a respective carbon credit value to a user on a mobile device, receiving a request for purchase from the user, verifying the selected at least one carbon offset product provenance by validating the metadata mapped with the at least one carbon offset product in the blockchain ledger, confirming an order of purchase of the selected carbon offset product if the at least one carbon offset product provenance is validated. The process further includes the step of generating a digital certificate based on the confirmed order, the digital certificate comprising the carbon credit value associated with the purchased carbon offset product.
