Under varying carbon tax rates ranging from 0.01 to 0.20 RMB yuan per kg carbon dioxide equivalence (CO2eq), the model is expressed in YALMIP toolbox and exactly solved by an optimization kit through rational parameter inputs. Exact solutions about the network design and product flows are got under different carbon tax rates. Results show that when the policy of progressive carbon tax rates comes into effect, through fine-tuning strategies on the distribution network, the cold chain service operator can decrease at most 30% carbon emission, with total corresponding operation cost rising by less than 10%. The final conclusion is that, from the viewpoint of operation optimization, the proposed carbon tax-constrained model and the exact solution method, can find optimal design for the urban cold chain distribution network, with cost pressures from newly added carbon tax partly offset, as lays a foundation for the service operator’s forwarding-looking operation decisions.
