Supply chain operation optimization considering green investment and carbon pledge financing

With the requirements of carbon peaking and carbon neutrality, low-carbon economic development pattern has been widely implemented in countries around the world. Under carbon trading market mechanism, enterprises can reduce carbon emissions through green investment to gain more green preference based market demand, and use carbon assets for innovative financing to alleviate financing problems. This paper investigates a supply chain operational decision problem, which contains purchasing, production, financing and carbon emission reduction investment. For the new problem, a mixed-integer linear programming model is established, which incorporates the decisions of green investment, carbon emission rights pledge financing, multiple products production, resource purchasing, and green preference based market demand. Then the effectiveness of the proposed model is tested by CPLEX using a series of practice-based randomly generated instances. The computational results are compared with that of the referenced model, which does not consider green investment. The comparative results show the significance of revitalizing carbon assets, and offer valuable insights for carbon abatement and sustainable development.
