The Global Centre for Maritime Decarbonisation (GCMD) on Tuesday (15 April) introduced a free cost and compliance calculator that has been developed by its team based on the newly approved greenhouse gas (GHG) emissions pricing framework by the Marine Environment Protection Committee during its 83rd session (MPEC 83).
The calculator will help maritime stakeholders explore how the two-tiered, GHG Fuel Intensity (GFI)-linked pricing system could impact operational costs.
GCMD said the buzz around International Maritime Organization’s MEPC 83 and the newly approved GHG emissions pricing framework has been intense — and understandably so.
“To help make sense of it, our CEO Prof. Lynn Loo started with handwritten trajectory calculations to break down the core workings,” it said in a social media post.
“Building on that, our team has developed a simple, accessible cost and compliance calculator to help you explore how the two-tiered, GFI-linked pricing system could impact operational costs.”
The calculator is just one input—its results should be considered alongside other economic and operational factors to inform commercial decisions.
The tool covers covers heavy fuel oil (HFO), liquified natural gas (LNG), B24 biofuel, e-ammonia and bio-methanol.
“Whether you’re assessing fuel options, planning newbuilds, or just trying to get a feel for what this might mean for your operations — this tool offers a useful first-cut view. For added clarity, we’ve included the workings on the side so you can trace the calculation process,” GCMD added.
