An integrated framework for carbon footprinting at container seaports: the case study of a Chinese port

The objective of this research is to establish an integrated framework for carbon footprinting (CF) at container seaports (CSs). Three methodological approaches are used in this research: the multiple case study to choose suitable evaluation methods, the case study for verification of the proposed framework, and the quantitative method to calculate the emissions. The proposed integrated framework consists of five modules: policy components, sources structure, input data, emissions estimation and mitigation strategies. The effectiveness of the integrated framework is demonstrated through the practical application in Qingdao Port in China. The case study results in the detailed estimation of CO₂ emissions and detects the problem of data collection and data accuracy for CF and the necessity of stakeholders’ cooperation. The integrated framework serves to evaluate, analyze and control CO₂ emissions from the CS operations.
