Template:Emissions transfer of allowances summ
Curious conditionality, across all three versions, where the {{{{{1}}}DP}} specifies a {{{{{1}}}|Holding Account}} from which {{{{{1}}}|Allowances}} must be delivered, and not just the account to which they must be delivered. Quite why it should matter whence the {{{{{1}}}|Allowances}} come we cannot say — a vague fretfulness about theft perhaps? — but ok; let’s run with it.
Note, in any case, its moderation in IETA (5.2) whereby one has an obligation to make sure there are sufficient allowances in your account to satisfy your delivery obligation. So even though you can’t be forced to deliver from anywhere else, you can be sued for losses arising from your failure to ensure there was something to deliver in your Holding Account. All rather cack-handed, but in “fundamental upshot” terms, this does get to the right place.
The transfer is done once the {{{{{1}}}|Allowances}} hit the {{{{{1}}}RP}}’s account (I know, I know: you don’t say.) But wait: there is an interesting use of the word “whereupon” here, upon which we dwell in a bit more detail in the premium section.
