DNV verifies updated record numbers for avoided CO₂ emissions for Jotun-coated vessels
Global manufacturer of marine coatings Jotun reports an estimated 11.8 million tonnes of avoided CO₂ emissions for vessels coated with its products in 2025 – an increase from 11.1 million tonnes from the year before. The result is verified based on an independent technical evaluation conducted by DNV.
The verified avoided emissions 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.
“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,” said Morten Sten Johansen, Global Category Director Hull Performance at Jotun.In 2024 Jotun presented their avoided emissions to be 11.1 million tonnes CO₂ in avoided emissions for vessels coated by Jotun products, based on the same approach and DNV verification methodology.
“In addition to the avoided emissions estimate, we estimate this level of performance to correspond to fuel cost savings of approximately USD 2 billion. To bring the number into perspective, 11.8 million tonnes CO₂ is comparable to the annual greenhouse gas emissions of approximately 2.5 million gasoline-powered cars, based on calculations from the US EPA. These results underline the scale of potential operational value associated with hull performance,” said Johansen in Jotun.
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 5‑year drydocking interval.
