Argentina’s Senate has opened joint committee debates on two bills that would create the country’s first national framework for the voluntary carbon market, with President Javier Milei signalling support and sponsors pushing to merge the texts into a single bill that could reach a floor vote. For a jurisdiction that hosts carbon projects, a private exchange, and a national registry but no governing law, the outcome will determine whether Argentine supply becomes easier or harder for international buyers to contract.
What the Senate Is Actually Debating
Senate commissions reviewed bill S-808/2026, a Regulatory Framework for Voluntary Carbon Markets, alongside a second proposal, according to Quantum Commodity Intelligence. The bill was formally presented at the Senate in May, and the current push is to unify the two texts into one that could soon be voted on.
This is not the first attempt. Multiple draft bills were introduced in the Argentine Congress in 2024, none of which obtained committee opinion. The political context has shifted since: Milei, who proposed a national cap-and-trade system as part of his omnibus reform bill in December 2023 only to see it stripped from the April 2024 draft, is now signalling support for a voluntary market framework. A voluntary market law is a lighter lift than an ETS, and it fits a government that wants climate finance inflows without domestic compliance obligations.
A Market That Exists Without Rules
Argentina already has the pieces of a carbon market. What it lacks is the legal connective tissue.
On the supply side, the national registry RENAMI tracks mitigation projects and credits issued under international standards such as Verra and Gold Standard. But RENAMI is a transparency database, not a crediting authority: registration is voluntary, few projects are listed, and more than half of those listings have expired, according to the Center on Global Energy Policy’s country framework.
On the market side, trading happens on private infrastructure. The Bolsa Argentina de Carbono (BACX), built on ACX technology, runs a digital marketplace for credits across international standards with its own accreditation and due diligence, but it is not integrated with RENAMI and operates without government oversight. The Buenos Aires exchange BYMA lists what it calls carbon certificates, with just two projects on its database as of January 2026, and the securities regulator CNV explicitly does not supervise that activity.
In other words, project developers, brokers, and buyers are already transacting Argentine credits under a patchwork of private rules. A national law would decide who supervises what.
What a Framework Would Change
Based on the proposals under discussion, three shifts matter most.
First, a designated authority. At least one bill designates the Undersecretariat of Environment as the national enforcement authority, responsible for approving a carbon market strategy, defining eligible project types, managing RENAMI, and issuing technical guidelines. That would convert today’s voluntary registry into the backbone of a regulated system.
Second, hard obligations with sanctions. Draft provisions would require projects to register with RENAMI within 30 days of credit issuance, with violations drawing warnings, disqualification from registering or transferring credits for up to five years, and fines of up to 1,000 times entry-level public administration salaries.
Third, a foundation for Article 6. Argentina has stated its intention to align with the Paris Agreement’s Article 6, but has no rules yet for internationally transferred mitigation outcomes or corresponding adjustments. A national framework is the precondition: without a designated authority and a functioning registry, Argentina cannot authorise ITMO transfers, and its credits remain confined to voluntary claims.
Why Buyers and Developers Should Care
Argentina is a credible supply jurisdiction in waiting. Its eligible project sectors under existing guidance span REDD+, agriculture and land use, waste management, and industrial processes. The provinces are already moving: Misiones, Santa Fe, Jujuy, and Córdoba have introduced their own initiatives, and in June Verra approved the Misiones provincial forest conservation programme, a jurisdictional approach that could anchor large-scale supply.
A federal framework would resolve the growing tension between provincial schemes and national accounting, and it would give buyers something Argentina cannot offer today: legal certainty about who owns a credit, how it is registered, and whether it could one day carry a corresponding adjustment. For developers, the calculus cuts both ways. Regulation brings credibility and potentially access to compliance-linked demand, but also registration deadlines, sanctions, and a supervisor where none exists now.
What to Watch
The near-term checkpoints are legislative. Watch whether the two bills merge into a single text, whether the unified bill reaches a Senate floor vote, and whether the final version keeps the Undersecretariat of Environment as the enforcement authority. Beyond the vote, the implementation questions are the real story: how quickly RENAMI registration becomes mandatory in practice, how the framework treats existing BACX and BYMA infrastructure, and whether Argentina follows through with Article 6 authorisation rules.
For buyers with Argentine exposure, the practical posture is to map current contracts against the draft obligations now. If the law passes in something close to its debated form, credits from unregistered projects could face a legitimacy discount, while early movers into registered, provincially anchored supply, starting with Misiones, could find themselves holding the most bankable tonnes in the country.
