Argentina's Senate Passes Carbon Market Bill 60-2, Eyeing $3.9 Billion Exports

Argentina's Senate approved a national carbon market framework by 60 votes to two on Thursday, October 29, moving the country closer to a regulated credit market that industry estimates value at up to $3.9 billion in annual exports.

The bill now heads to the Chamber of Deputies, where approval is required before it becomes law. The margin in the Senate suggests the government has the votes; the lower house will decide whether it also has the appetite.

What does the bill actually establish?

The legislation sets rules for generating, registering and commercialising carbon credits from projects that reduce or remove greenhouse gas emissions. Qualifying project types include:

• forest conservation
• reforestation
• renewable energy initiatives

The framework is anchored in Article 6 of the Paris Agreement, which governs international carbon market mechanisms. Its stated aims are to attract investment, clarify carbon credit ownership and open access to international markets.

A central institutional element is the creation of the National Emissions Reduction Registry, known as ReNaRe. The registry is intended to provide public oversight and improve the traceability of carbon credits — the plumbing that credible markets require.

The bill also recognises credits as independent financial assets and permits their use in financial instruments. That classification matters: it puts carbon credits inside the regulated financial system rather than in a voluntary grey zone.

Registered projects would receive up to 30 years of fiscal stability, a long horizon designed to lock in investor confidence.

On international transfers, the bill includes safeguards. Transfers used towards another country's climate commitments would require government authorisation and accounting adjustments to prevent double counting. In plain terms, one tonne of CO2 cannot be sold twice under two flags.

How large is the market opportunity?

Industry projections cited by Argentine media put potential carbon credit export revenues between $1.4 billion and $3.9 billion annually, depending on market scenarios. The upper end would position Argentina as a significant supplier in international environmental commodity markets.

The range is wide, which is honest: Article 6 market prices remain unsettled, and demand depends on how strictly buyer countries police credit quality.

What concerns do environmental groups raise?

The proposal faces scrutiny on three fronts: land rights, provincial authority and environmental safeguards.

Environmental organisations have warned that weak oversight could encourage greenwashing, deforestation and conflicts involving local and Indigenous communities. The registry and traceability provisions are the bill's answer to those concerns. Whether they suffice is untested.

The critique is not marginal. Argentina's credit supply would draw heavily on land-based projects — forest conservation and reforestation — precisely the categories where tenure disputes and Indigenous land claims concentrate.

What happens next?

The Chamber of Deputies vote is the decisive milestone. It will test whether Argentina can convert market ambition into law while keeping environmental protections credible enough for international buyers to accept the credits.

Until the lower house acts, the $3.9 billion figure remains a projection, not a revenue line.
