IMO Net-Zero Calculator
This Excel model helps shipowners, operators, and compliance officers assess a vessel’s alignment with IMO’s net-zero targets by calculating greenhouse gas intensity, expected penalties, and compliance status based on fuel mix and operational data.
The tool supports scenario-based analysis, enabling users to compare fuel strategies, energy-saving measures, and technology pathways until 2050 where the framework applies. With flexible inputs for fuel properties, prices, and regulatory baselines, this calculator offers a practical framework for evaluating IMO Net-Zero alignment, tracking GFS trajectories, and identifying cost-effective mitigation options.
