Comparative Analysis of Ship Carbon Emission Monitoring Methods Based on MRV Rules

Transportation industry accounts for 20% of the world's energy consumption and greenhouse gas methods, and research on ship carbon emission monitoring methods can help achieve the goal of operating ship emission reduction. By analyzing the MRV rules, the four monitoring methods of BDN tracking, tank level measurement, flow meter monitoring and direct carbon emission measurement were compared and analyzed in terms of equipment cost, data collection and verification cost, monitoring accuracy and feedback real-time.Results indicate that future carbon emission calculations are mainly based on fuel consumption monitoring, such as BDN tracking, fuel Tank sounding monitoring and flow meter monitoring.
