Blue Sky Maritime Coalition Report Examines Emission Calculations

The Blue Sky Maritime Coalition (BSMC) released a report June 23 that recommends methodologies for calculating Scope 1 greenhouse gas (GHG) emissions from marine vessels.

“Consistent calculations and transparent methodologies for measuring and tracking CO2 emissions are key components for reaching the maritime industry’s decarbonization goals,” said David Cummins, BSMC president and CEO.

 “This report was developed to help  establish a common approach to managing data and identifying relevant comparison criteria for various emissions calculation methodologies.”

Developed by BSMC’s Measurements and Operational Efficiency Workstream, the report defines the various calculation methodologies and details the current maturity of each. The workstream concluded that consistency is critical to accurately understanding emissions from this sector, and it recommends a standardized approach for estimating both absolute and relative (i.e., intensity) Scope 1 emissions. As the coalition continues to monitor emissions estimation and reporting developments, it will update this report to provide an evergreen resource for marine vessel GHG emissions. 

“Measuring and monitoring are two very important components of getting to a net-zero future,” Cummins said. “It is critical that industry continue to collaborate on these approaches, and this report is another step in that direction.”
