This invention discloses a consumer behavior-driven carbon credit conversion method and application system. By collecting purchase data of near-expiry food, the system calculates emission reductions by category carbon reduction coefficient multiplied by measurement, and maps these reductions to carbon credits in real time (1kg CO₂e = 10 credits, error ≤5%), and connects to a third-party carbon trading platform. This solves the problems of coarse calculations and poor real-time performance in existing methods, and can accurately incentivize users to engage in green consumption. It is suitable for carbon credit scenarios on community O2O platforms.

Nutrient prediction systems and methods can include systems and methods of training and testing machine-learning models and food purchase data collection and analysis. For example, a food purchase data collection and analysis system, under the control of at least one processor, can include a purchase data collection device to collect food purchase data at a point of sale of a food basket including information regarding food items purchased and location of the food purchase, an analysis server including a machine-learning model predicting nutrient availability based on the food purchase data, and a network for transmitting the food purchase data from the purchase data collection device to the analysis server for analysis using the machine-learning model.
