GMF PRODUCES INSIGHT INTO ‘BOOK AND CLAIM’

Aug 6, 2026 | Marine fuel & lubricant news

According to the Global Maritime Forum (GMF), voluntary book and claim chain-of-custody systems have been gaining momentum as a market tool for maritime decarbonisation, with emerging infrastructure, evolving standards, and guidance acting as key drivers of uptake.

However, participation in these systems has thus far been limited by both their complexity and the fragmentation and lack of transparency around market norms. A new insight brief, Accelerating market participation in maritime book and claim, explores how stakeholders can reduce friction for demand-side participants to support market development. There are three areas that make it easier for participants to navigate the market, compare options, and engage with suppliers:

  • Improving market understanding
  • Increasing uniformity in core market components
  • Enhancing transparency in sustainable maritime fuel attributes

The brief outlines how book and claim systems can support the broader sustainable maritime fuel ecosystem, ultimately helping accelerate the adoption of low-emission fuels and the decarbonisation of the shipping sector.
