Carbon emission reduction determination method and device, equipment and storage medium

The invention discloses a carbon emission reduction determination method, device and equipment and a storage medium, and belongs to the technical field of carbon emission reduction. The method comprises the following steps: acquiring card swiping data and vehicle order data of rail transit of a user; performing trip chain identification through a preset matrix decomposition model based on the card swiping data and the vehicle order data to obtain user commuting trip chain data; obtaining carbon emission of each commuting trip chain based on the user commuting trip chain data; and obtaining carbon emission reduction data of each commuting trip chain according to the carbon emission, linking vehicle order data and rail transit card swiping data, deeply analyzing a competing relationship between a car sharing service and rail transit, performing multi-dimensional analysis on the carbon emission reduction benefit of the vehicle, and estimating the carbon saving benefit of the user commuting trip chain.
