Chile approves the Paris Agreement Crediting Mechanism for carbon tax compliance: what it means for credit buyers

Chile's Ministry of the Environment has formally recognised the Paris Agreement Crediting Mechanism as an eligible standard for generating credits that can be used to satisfy the country's carbon tax obligations. The decision means that companies subject to Chile's carbon tax now have access to a new category of internationally recognised offsets alongside whatever domestic mechanisms were previously available. It is a meaningful regulatory signal in a Latin American market that has been building out its carbon pricing architecture over several years.

The Paris Agreement Crediting Mechanism, sometimes referred to as PACM, operates under Article 6 of the Paris Agreement and is designed to channel finance toward emissions reduction activities while maintaining environmental integrity through international oversight. Recognising PACM within a national tax compliance framework is relatively uncommon, and Chile's move puts it among a small group of jurisdictions experimenting with Article 6 instruments as a direct bridge to domestic carbon pricing. For companies operating in Chile's taxable sectors, the decision expands the menu of eligible offsets they can procure.

For procurement and compliance teams managing carbon tax liabilities in Chile, the practical implication is that PACM credits sourced from internationally approved projects can now count toward their tax obligations. That distinction matters for due diligence workflows, since PACM credits carry a specific set of accounting rules and corresponding adjustments that differ from voluntary carbon market standards. Buyers will need to understand how those rules interact with their own Scope 1 and Scope 3 reporting positions before treating PACM credits as a straightforward substitute for other offset types.

The timing of this recognition is worth watching in the context of broader Article 6 market development. International negotiations on the detailed rules governing Article 6.4, the mechanism that underpins PACM, have been progressing slowly, and jurisdictions that move early to integrate PACM into domestic compliance frameworks may influence how the market prices these credits as supply begins to develop. Chile's decision could attract project developers looking for host country demand signals.

For ESG professionals with supply chains or operations in Chile, the most immediate action is to assess whether carbon tax exposure exists in those operations and to map that exposure against the new eligibility rules. The broader picture is that Article 6 instruments are gradually moving from a theoretical policy construct to a live compliance tool, and jurisdictions like Chile are building the regulatory architecture that will define how those tools function in practice.
