A "common carbon language" can accelerate short-term emissions cuts

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.‍

Launching FREE Carbon Estimator for commercial shipping professionals

‍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.

Siglar Carbon help validate prediction model for Climate TRACE

We are excited to see the first version of Climate TRACE world emissions map and intelligence being published, and proud to say that Siglar Carbon played a small part, reviewing their maritime prediction model. We share the goal of making emissions insight available, because effective decarbonization starts with detailed knowledge of emissions sources – also in the maritime industry.

Emission Schemes

Djibouti Sovereign Carbon Initiative

The Governments of Djibouti and Gabon have introduced sovereign carbon registry frameworks that apply a carbon cost to qualifying ship movements to and from their ports.

African Sovereign Carbon Initiatives: Countries Under Discussion

A growing number of African countries are in active discussion about introducing their own Sovereign Carbon Initiatives for maritime shipping, following the model pioneered by Djibouti (2023) and Gabon (2025). No schemes are yet in force in these countries, but the commercial direction of travel is clear: more African port calls are likely to carry a carbon cost in the coming years.

Türkiye Shipping Greenhouse Gas Emissions Fee

Türkiye has adopted a shipping-specific greenhouse gas fee intended to apply to greenhouse gas emissions from commercial ships calling at, or departing from, Turkish ports for cargo or passenger operations. The operational details are to be defined in secondary regulation that has not yet been published.
