Brazilian officials will meet their Chinese counterparts as early as next week to discuss bilateral carbon market cooperation, including a potential agreement under Article 6.2 of the Paris Agreement, with Brazil reportedly targeting a carbon credit accord by COP31. If the talks mature into a deal, they would connect one of the world’s largest potential suppliers of internationally transferred mitigation outcomes (ITMOs) with the one economy whose participation could transform Article 6 from a boutique government-to-government niche into a market with real scale.
What Is on the Table
The reporting, from Carbon Pulse and a source-based Reuters story published on September 9, is deliberately thin on detail. No draft text, volume targets or sector scope have been disclosed, and neither government has confirmed the agenda publicly. What is confirmed is the direction: Brazil wants China as a buyer of its carbon credits, and it wants an agreement in place by COP31, the UN climate summit later this year.
That timing is not accidental. Brazil used its COP30 presidency to push carbon markets up the multilateral agenda, and a bilateral Article 6.2 framework with China, announced at or before COP31, would be the most consequential deliverable it could still claim. A source-driven leak one week before the delegation travels is also a classic way to test the political water on both sides.
Why China Is the Demand Side That Matters
Article 6.2 lets countries trade mitigation outcomes bilaterally, with corresponding adjustments to prevent double counting. So far, the buyer side of that market has been dominated by a small group of wealthy, land-constrained states: Switzerland, Singapore, Japan, South Korea. Their deals are real but modest in volume, and they have not been enough to absorb the supply pipeline that host countries across Latin America, Africa and Southeast Asia are building.
China is a different order of magnitude. It operates the world’s largest emissions trading system by covered emissions, and its climate diplomacy has historically favored domestically anchored instruments over cross-border credit purchases. Beijing has engaged with Article 6 mostly as a potential seller of its own credits and as a rule-maker, not as a buyer. A Chinese decision to purchase ITMOs, even on a pilot scale, would reprice expectations for the entire cooperative market, because it would signal that the largest emerging economy sees authorized foreign credits as compatible with its own accounting and industrial strategy.
For now, that is a hypothesis, not a fact. The meeting is about cooperation, which could mean anything from ITMO trading to registry interoperability, MRV technical exchange or recognition of standards. The Reuters framing, however, explicitly casts China as a prospective buyer of Brazilian credits, which is the strongest version of the story.
Why Brazil Needs the Outlet
Brazil’s position is the mirror image. It has spent the past two years assembling the legal machinery for carbon credit exports under Article 6, including authorization rules and a domestic cap-and-trade system, and it sits on one of the deepest nature-based supply bases in the world. What it lacks is committed sovereign demand at scale.
Existing Article 6 buyers have signed deals with smaller host countries and tendered for volumes in the low millions of tonnes. Brazil’s supply ambitions, spanning avoided deforestation, reforestation, agriculture and industrial decarbonization, are far larger. Only a buyer of China’s scale could plausibly absorb that pipeline without depressing prices. The courtship is therefore structural, not opportunistic: Brazil needs demand that matches its supply narrative before its own market architecture goes live.
What It Means for Buyers and Developers
For corporate buyers, nothing changes this week. An Article 6.2 framework between two governments is about correspondingly adjusted sovereign transfers, not voluntary procurement, and any deal is months of negotiation away. The relevant signal is strategic: if China enters Article 6 as a buyer, the competition for high-quality authorized supply intensifies, and the price spread between authorized and non-authorized credits widens. Buyers with 2030 targets should treat this as one more data point in favor of securing authorized supply early rather than assuming it will stay available and cheap.
For project developers in Brazil, the implication is more direct. Sovereign-level Chinese demand would flow through the same integrity screens that other Article 6 buyers apply: host-country authorization, robust baselines, credible MRV. Developers whose projects can meet those standards stand closest to any future government-backed offtake. Those selling into the unregulated voluntary segment would not benefit automatically, because a bilateral Article 6.2 deal creates a parallel, higher-integrity channel rather than lifting all credits equally.
What to Watch
Three markers will show whether this is a real negotiation or diplomatic positioning. First, the readout from next week’s meeting: any mention of a memorandum, working group or Article 6.2 text would move the story from intention to process. Second, scope: whether talks cover ITMO trading proper or stop at looser cooperation on registries and standards, which would be meaningful but far less market-moving. Third, the COP31 deadline itself. A target date gives both sides an incentive to announce something; what matters is whether what they announce includes authorization mechanics and corresponding adjustments, or just another framework without volume behind it.
