Lloyd’s Register Report Highlights 30% to 70% Emissions Cut from Onboard Carbon Capture

Onboard carbon capture systems have the potential to reduce vessel carbon dioxide emissions by between 30% and 70%, according to findings from a newly released study by classification society Lloyd’s Register.

The assessment highlights the role capturing emissions directly at the exhaust funnel can play across the existing commercial fleet. As shipowners and operators evaluate pathway options to comply with increasingly stringent environmental standards, onboard capture presents an immediate technical avenue to limit greenhouse gas output.

The findings underscore that carbon capture installations offer a practical operational mechanism to bridge the gap while global supply chains for low- and zero-carbon alternative fuels continue to mature and scale.

By curbing emissions from conventional marine fuel combustion, onboard systems allow existing tonnage to achieve marked efficiency improvements and lower overall carbon intensity during the ongoing maritime energy transition.
