Supply chain carbon footprint monitoring and evaluating method based on radio frequency identification technology

The invention discloses a supply chain carbon footprint monitoring and evaluating method based on a radio frequency identification technology, and the method comprises the following steps: marking all commodities through a radio frequency identification tag in each stage of raw material purchasing, product manufacturing, transportation, warehousing and selling to final consumers of a supply chain; collecting real-time data of commodities with radio frequency identification tags in each supply chain link through radio frequency identification reading equipment; calculating the carbon footprint of the commodity in each link by using a preset carbon emission calculation model; summarizing each supply chain link to obtain a total carbon footprint value of the whole supply chain; commodity carbon footprint data of each link is analyzed in combination with the total carbon footprint value of the whole supply chain, and a key carbon emission source is identified; and obtaining emission reduction suggestions and supp
