Marine coatings manufacturer Jotun reports an estimated 11.8m tonnes of avoided CO₂ emissions for vessels coated with its products in 2025 – an increase from 11.1m tonnes from the year before.
This result has been verified through an independent technical evaluation conducted by DNV. The verified avoided emissions figure is based on the average speed loss of the vessels included in the evaluation, compared to an industry benchmark referenced in ISO 19030. The evaluation uses the DNV MASTERv2 emission prediction model combined with AIS data and Jotun-provided data on average speed loss over a five-year drydocking cycle.
Morten Sten Johansen, Jotun Global Category Director, Hull Performance, said: “This evaluation reflects a year-on-year increase in the verified avoided emissions estimate, and helps quantify the link between hull performance, speed loss, and emissions. We are pleased to have an independent verification of the avoided emissions estimate based on documented speed loss performance. As the market leader in marine coatings, we are committed to delivering value to our customers that is backed up by third-party technical evaluations. In addition to the avoided emissions estimate, we estimate this level of performance to correspond to fuel cost savings of approximately US$ 2bn. To bring the number into perspective, 11.8m tonnes CO₂ is comparable to the annual greenhouse gas emissions of approximately 2.5m gasoline-powered cars, based on calculations from the US EPA. These results underline the scale of potential operational value associated with hull performance.”
The 2025 figure is verified on the same premises as Jotun presented for its 2024 numbers, with a margin of +2.5 million tonnes and -2.0 million tonnes CO₂. The assessment follows ISO 19030 principles by measuring average speed loss over the final four years in a five-year drydocking interval.
Olav Rognebakke, DNV Head of Section Hydrodynamics and Stability, said: “We are pleased to support Jotun on this project. This verification quantifies an avoided CO₂ emissions estimate for the vessels included in the evaluation and provides a documented basis for discussing the potential emissions effect associated with hull performance.”
Johansen concluded: “As the home of hull performance, we will continue to focus on delivering quantifiable value to the maritime industry through our products and solutions. These verified results highlight the role hull performance can play in improving energy efficiency. Our investments into R&D and industry collaboration are part of our clean shipping commitment – helping the industry to cut carbon emissions, preserve fuel and protect biodiversity.”
