EU shipping emissions rose in 2025. The ships did not emit more. The reported increase comes entirely from vessels that entered the reporting rules in 2025; follow the same ships through both years and emissions fell. Below the CO₂ line, methane rose sharply as LNG dual fuel ships reached the water, and from 2026 that methane becomes billable, pushing the maritime EU ETS bill toward 100 million allowances. For owners and charterers, the headline MRV number is only the starting point. The exposure sits behind it.
The full storyWith the Carbon Estimator charterers, brokers and owners can predict and assess the environmental footprint from tanker voyages. In this post we look at five ways you can use the Carbon Estimator in your day-to-day chartering activities.
Siglar argues that a "common carbon language" is needed to accelerate short-term cuts in maritime emissions. In an interview with Siglar CEO Sigmund Kyvik, he explains why he thinks a new language is necessary and how the launch of the free Siglar Carbon Estimator can kickstart the learning of this language.
Siglar Carbon launches a free and neutral tool for estimating and comparing emissions from tanker voyages. Using the Siglar Carbon Estimator to compare the carbon consequence of commercial decisions prior to fixing can unlock potential that lies within a commercial decarbonization of the shipping industry.
