Auctions

  • The next auction of allowances for installations (CHU) for the year 2022 will take place from 28 November, 12:00 to 30 November 2022, 17:00 (local time). This will be a first tranche of CHU from 2022. Another auction of CHU is planned before the deadline for the 2022 compliance year (30.04.2023). You will be informed of the date and exact quantity in due course.
  • The auction of allowances for aircrafts (CHUA) for the year 2022 took place from 5-7 September 2022. The auction has been cancelled without an award because the clearing price differed significantly from the applicable price on the secondary market in the EU (Article 48 paragraph 2 letter b CO2 Ordinance). The auction was repeated as follows: 24 October 2022, 12:00 to 26 October 2022, 17:00 (local time).

Pursuant to Article 48 paragraph 2 letter b of the CO2 Ordinance, the FOEN may cancel an auction without making an award if the clearing price in the auction period differs significantly from the applicable price on the secondary market in the EU.
