EEX Press Release - EEX publishes revised 2022 calendar for EUA auctions and 2023 auction calendar

    The European Energy Exchange (EEX) has published the revised 2022 auction calendar and the new 2023 auction calendars for the auctioning of the EU emission allowances (EUA) and EU aviation allowances (EUAA).

    The 2022 auction calendar has been adjusted for the period from September to December 2022 in accordance with the Auctioning Regulation1 due to the operation of the Market Stability Reserve (MSR), taking into account the publication of the 2021 total number of allowances in circulation (TNAC) in May 2022.
