The € question: Are you ready to surrender your first EU allowances?

The countdown is on: By 30 September 2025, all shipowners with EU voyages must surrender their first batch of EU ETS allowances. But are you ready? Do you know what your carbon bill will be? Where to get allowances, and when? For many shipowners, the financial clock is ticking, yet the full cost remains off the radar.

Carbon taxes set to reshape shipping

Carbon pricing is no longer a distant regulatory threat, as the EU ETS and FuelEU Maritime will add an estimated USD 6.1 billion to industry costs in 2025 alone. The IMO’s Global Fuel Intensity (GFI) measure is set to drive up costs even further—shipowners and charterers could be staring down a combined carbon bill approaching USD 50 billion by 2030.

Carbon pricing introduced in Djibouti and Gabon

The Sovereign Carbon Initiative, implemented in Djibouti and Gabon,  calculates the carbon cost as 50% of the total carbon footprint of a ship’s journey to or from Djibouti and Gabon, and the price is set at USD 17 per tonne of CO2e emissions. The principle behind the scheme is simple: those who pollute must pay.

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.
