Optimization Model of Carbon Footprint of Fresh Products in Cold Chain from the Energy Conservation and Emission Reduction Perspective

Abstract

The carbon footprint of the cold chain logistics system refers to the greenhouse gas emissions directly or indirectly caused in each link of the cold chain logistics activities. Because cold chain logistics is the main carbon emitter in the field of logistics, research on how to reduce carbon emissions in the field of cold chain logistics plays an important role in energy conservation and emission reduction. Based on the in-depth analysis of the carbon footprint of cold chain logistics, this paper introduces the distance coefficient and freshness parameters into the optimization model innovatively and uses the life cycle assessment method and input-output method to determine the calculation range of the carbon footprint of fresh products of each link in the cold chain logistics. The system calculates the carbon emissions generated by the production and operation activities of each place of origin, distribution center, retailer, and waste disposal during the circulation of fresh products. This paper establishes a carbon footprint optimization model to discuss how to balance carbon constraints and minimized costs. Through the analysis of the simulation results, from the perspective of the government and enterprises, corresponding countermeasures are put forward to more effectively achieve the goal of energy conservation and emission reduction and guide the cold chain logistics industry to sustainable development.

An electric vehicle routing model with charging stations consideration for sustainable logistics

“…Li et al . (2022b) and Hu et al . (2021) adopted above approach, where the environment cost was obtained through the unit price and carbon emission determined based on emission factor.…”

“…By analyzing existing research, it is found that many scholars convert carbon emission into carbon emission cost when studying cold chain logistics vehicle routing problems (Li et al, 2019a). Li et al (2022b) and Hu et al (2021) adopted above approach, where the environment cost was obtained through the unit price and carbon emission determined based on emission factor. At present, this method for calculating carbon emission cost has become the research mainstream (Chen et al, 2019;.…”

Low-Carbon Cold-Chain Logistics Path Optimization Problem Considering the Influence of Road Impedance

“…Liu et al [19] showe d that a joint distribution is less costly than a single distributi on in terms of carbon emissions and that the total cost is posit ively related to the cost of carbon emissions. Hu et al [20] fir st used the cycle evaluation method and the input-output met hod to calculate the range of carbon emissions during each st age of cold-chain logistics. To develop a mathematical model for carbon footprint optimization, Ning et al [21] developed a quantitative analysis of the carbon tax mechanism.…”

Vehicle Routing Problem with Deadline and Stochastic Service Times: Case of the Ice Cream Industry in Santiago City of Chile

“…Equations ( 3) and ( 4) indicate that vehicle k must leave and return to the depot. Restriction (5) forces each vehicle k to leave the node. Equation ( 6) represents the capacity constraint.…”

“…Some contracts with retailers involve penalties for delays within the established delivery times. Additionally, energy is required to maintain adequate temperature during distribution, and traffic conditions are different throughout the day [5]. Therefore, the impact of delays on delivering perishable food is more critical than general goods [6].…”
