The European Energy Exchange (EEX) has published the revised EUA auction calendar for the year 2026, after adjustments related to the phase-in of emissions from the maritime transport sector emissions in the EU ETS.
Maritime transport has been included in the EU ETS from 2024, with shipping companies required to surrender allowances for 40% of their verified emissions for 2024. The difference between verified emissions and surrendered allowances is to be cancelled from auctioning, pursuant to Articles 3gb and 12(3-e) of the ETS Directive. Furthermore, the auction volume has been increased to take into account the coverage of non-CO2 greenhouse gas emissions from maritime transport (CH4 and N2O), pursuant to Article 9 of the ETS Directive.
The overall impact on the 2026 auction volume is a decrease of approx. 52 million EUAs compared with the 2026 calendar published in July 2025.
The below table provides an overview of the adjusted 2026 auction volumes*:
| CAP3 | DE | PL | |

EUA auctions for the UK in respect of Northern Ireland
Pursuant to the Protocol on Ireland and Northern Ireland, the EU ETS applies to electricity generation in Northern Ireland. Therefore, the UK will auction a small volume of allowances corresponding to its share in the Union-wide cap.
Next year, EEX will conduct one EUA auction on behalf of Northern Ireland, scheduled for 7 October 2026 with an auction volume of 782,000 EUA**.
For further details please refer to the published auction calendar on the EEX website. Clearing and settlement of all emission allowances are conducted by the European Commodity Clearing (ECC).
*The volumes from September to December 2026 are preliminary and can be subject to adjustments.
