Template:M summ EUA Annex (d)(xii)
So many words.
Ok: so to deliver and receive EUAs you need to have approved registered accounts in side the EU ETS. these, once approved, qualify as Holding Accounts. Right. Then in order to perform an EUA Transaction, you need to tell your counterparty — specify to it, in the ’squad’s tedious argot — from which Holding Account you will be delivering EUAs, or into which Holding Account you will be receiving them. These are your Specified Holding Accounts. You can change these from time to time, as long as you give enough notice. You can specify your Specified Holding Accounts either in your Emissions Annex — in which case those designations will apply to all your emissions transactions — or in a Confirmation, in which case it will apply to that Transaction only.
Proper “gives you a thrill to be alive” stuff.
