Auctioning
28 countries (25 EU Member States plus Iceland, Liechtenstein and Norway) auction their EU ETS allowances on the common auction platform selected through a joint procurement procedure. Currently, the common auctioning platform is the European Energy Exchange (EEX).
Germany, Poland and the UK (for what concerns Northern Ireland) have opted-out of the common auctioning platform. Germany has nominated EEX as their opt-out platform, while Poland and the UK are using EEX to auction their allowances until further notice.
