The European Energy Exchange (EEX) has released an updated auction calendar for EU Emission Allowances (EUA) for the year 2026. The calendar has been adjusted for the period from June to December to incorporate the provisions of the amended European Climate Law.
This amendment includes the additional auctioning in 2026 of 50 million allowances for the Social Climate Fund. Of this amount, 10 million allowances are sourced from allowances originally allocated to Member States. Consequently, these 10 million allowances have been deducted from the initial member state volumes. These adjustments, along with the auctioning for the Social Climate Fund, will take effect from 1 June 2026.
The 2026 auction calendar will be subject to further adjustments. The operations of the Market Stability Reserve (MSR) can have an impact on the auction volume from September to December. Furthermore, the auctioning of allowances allocated to the Recovery and Resilience Facility will stop once the revenue targets for this Facility are reached, at the latest on 31 August.
An overview of the revised auction volumes is provided below:
| Period | EU CAP3 Volume per Auction | DE Volume per Auction | PL Volume per Auction |
