Executive Summary
Shipping stakeholders are advancing onboard carbon capture as a bridge option, while China pushes the IMO to speed rules and shore-side systems lag
- Onboard carbon capture is viewed as a transitional option while low and zero carbon fuels scale
- Post combustion systems are more mature and better suited to retrofits than pre combustion concepts
- Pilot projects have shown onboard capture can work and ship to shore transfer has been demonstrated
- Major barriers remain around regulation, emissions accounting, and recognition of captured CO2
- Ports and wider CCUS networks lack the capacity needed for routine offloading and handling
- China urged the IMO to issue initial OCCS guidelines in 2026 and finish them by 2028
- China proposed real time monitoring, verification, and reporting integrated into existing IMO systems
Quick Facts
- What: Onboard carbon capture rules and deployment
- Where: Global shipping and IMO headquarters in London
- Why: To cut ship emissions while fuel transitions and port systems develop
- Who: Shipowners, IMO members, and China
- When: During 2025 with milestones for 2026 and 2028
