ClassNK has published a new guidebook titled 'Framework for Implementing Carbon Capture Systems on Ships'. This book is part of a series of guidebooks on assessing greenhouse gas emissions from ships and helps owners, operators, and other stakeholders in implementing onboard carbon capture systems (OCCS).
Practical Guide for Stakeholders
The guidebook includes practical guidelines for understanding key considerations in OCCS projects and facilitates discussions among relevant parties in this field. Implementing OCCS requires attention to the value chain from CO2 capture to storage and other final treatment methods. Additionally, mechanisms for quantifying and verifying greenhouse gas emission reductions must be considered.

Importance of Carbon Capture Systems
This book examines technical, infrastructural, legal considerations, and assessment of emission reductions, and can serve as a tool to support discussions among stakeholders and review specific OCCS projects. The maritime industry is striving to reduce greenhouse gases through various methods, including operational improvements, the introduction of energy-saving technologies, and the transition to alternative fuels.
Furthermore, CO2 capture on ships, where CO2 is captured from ship exhaust gases, processed, and temporarily stored, has been recognized as one of the important options for reducing greenhouse gas emissions. Pilot projects and discussions regarding related legal frameworks are progressing internationally.
Challenges of Implementing OCCS
However, converting the use of OCCS into actual emission reductions requires more than just existing systems on ships. Pathways for the discharge, transportation, storage, sequestration, or utilization of captured CO2 must be provided, and mechanisms for quantifying and verifying emission reductions must exist. These considerations include technical, infrastructural, legal aspects, and assessment of emission reductions, which require a broad perspective of the project.
ClassNK, by developing the 'Guide for CO2 Capture and Storage Systems on Ships', aims to establish safety and technical requirements for these systems and gather knowledge through pilot projects and experience from various greenhouse gas certification services. Based on this knowledge and experience, the guidebook has been prepared to assist stakeholders in implementing OCCS and familiarize them with the relevant considerations.
ClassNK will continue to support the maritime industry's efforts to reduce carbon by providing relevant information.
