Exploring the carbon abatement measures in maritime supply chain: a scenario-based system dynamics approach
基于系统动力学方法构建海运供应链碳减排模型，以上海港为例模拟不同减排措施的效果，发现岸电减排潜力巨大，而排放交易机制反而可能增加CO2排放。
The rapid growth of the global economy has boosted the shipping industry, but it has also increased energy consumption and exhaust emissions. Based on the system dynamics method, we construct a carbon abatement model of maritime supply chain, in which the interaction among company, economy, energy, environment, and policy is deeply analysed. The effect of various carbon abatement measures is simulated with a case study of Shanghai Port. The results prove that the shore power has tremendous potential for reducing emissions. Interestingly, the emission trading scheme has little effect on emission reduction. Conversely, it will increase CO2 emissions because of the vicious circle of higher CO2 production and decreased CO2 treatment capability. Case 4 is the best alternative for reducing CO2 emissions in maritime supply chain when combined measures are applied, regardless of the emission reduction effect or carbon emission intensity. Thus, it is most effective to mobilise all kinds of resources to reduce CO2 emissions when conditions permit.
