ABS has set out a technical position on IMO mid-term measures, arguing for a balanced framework that reflects fuel availability, technology readiness and operating realities across the global fleet, according to ABS.
The classification society said its open letter, titled The ABS View: A Practical Path Forward on IMO Mid-Term Measures, supports one international approach to shipping emissions reduction while recognising that implementation will differ across vessel segments, operating profiles and access to fuels and infrastructure.
ABS said its assessment examined fuel availability, technology readiness and cost implications linked to the Net Zero Framework and alternative proposals. It concluded that the transition is moving through multiple pathways rather than a single route, and that no existing proposal fully addresses the complexity of the challenge.
“There is a clear direction set by the IMO, but the pathway forward has become increasingly complex for the industry,” said John McDonald, ABS chairman and chief executive. “Our role is to provide technical clarity based on factual data at a time when there are many competing perspectives. By staying grounded in what is achievable across the global fleet, we can help keep the industry focused on practical steps that support the targets already set and move the transition in the right direction.”
ABS said a practical framework should combine the strongest elements of existing IMO proposals, preserve flexibility, align measures with fuel availability and support emissions reduction that can be delivered in practice. The society also pointed to energy efficiency as a near-term measure that can be applied across the fleet today, alongside the longer-term development of alternative fuels.
ABS is a US-based classification society formally known as the American Bureau of Shipping. It provides classification, technical, engineering and advisory services for the marine and offshore sectors, including rules, guidance and assessment work covering ship safety, offshore structures, statutory compliance and maritime technology.
