ClassNK has released a new handbook entitled 'Onboard Carbon Capture Systems Implementation Framework' as part of its Handbook on Ship GHG Emissions Evaluation series.

The handbook provides practical guidance for shipowners, operators, and other stakeholders considering the introduction of onboard carbon capture systems (OCCS). It is intended to help them understand the considerations involved across an entire OCCS project and to facilitate discussions among relevant parties and consideration of OCCS implementation.

These include Monitoring, Reporting and Verification (MRV) and Chain of Custody (CoC) systems for managing captured CO2 and its associated attribute information.
