Abstract:

To promote the green and low-carbon development of container ports and achieve the carbon peak target, from the perspective of port operators, the combinatorial optimization issue of investments in emission reduction projects of container ports under the carbon peak target is researched at the level of port overall operation planning. Firstly, the measurement scope of carbon emission at container ports is defined. Combined with the existing emission reduction technology of ports, a carbon emission measurement model of container ports based on energy consumption is established and then a calculation method is derived to measure effects of implementing emission reduction projects. Furthermore, a combinatorial optimization model of investments in emission reduction projects of container ports under the carbon peak target is presented with the objective of the minimum carbon emission in a planning year and the variables of the number of emission reduction projects planned to be implemented and the number of equipment updates. Finally, the optimal combinatorial strategy of investments in emission reduction projects is obtained through a case study of a container terminal and numerical analyses are made to obtain several management insights: (1) Influences of the planned annual investment amount on emission reduction are discussed. By presenting the concept of cost performance, the results are conducted an in-depth analysis and this method can provide theoretical support for port managers to determine the investment scheme with the highest cost performance. (2) The impact of container throughput on emission reduction are analysed. It is found that when the port can meet the operation demand corresponding to the change of container throughput, its managers can formulate the same optimal emission reduction project investment strategy, that is, the optimal strategy. In summary, it can provide port managers with the optimal combinatorial strategy of investments in emission reduction projects and has important application value for container ports to achieve the carbon peak target.
