Since the implementation of China's dual carbon policy, the whole industry has actively carried out low-carbon and green transformation. As a vital industry of China's economic development, logistics industry is a "large carbon emissions industry", so it should make efforts to respond to the call of "double carbon". The comprehensive modal emissions modeling (CMEM) for cold chain logistics distribution is introduced in this study, along with the calculation method for refrigerating and distributing carbon emissions during the cold chain vehicle distribution process. A mathematical model for distribution path planning and a better ant colony solution method were developed with the goal of reducing overall carbon emissions. By contrasting the numerical experiments with the path planning under the time and cost objectives, the viability of the model and algorithm was confirmed. This study has a good theoretical explanation and practical guiding significance for the cold chain logistics industry to implement green transformation to assist the realization of dual carbon goals.
