Summary

Resolution 363/2021 creates the “Registro Nacional de Proyectos de Mitigación del Cambio Climático” (ReNaMi) under the climate authority, aiming to register and systematise mitigation projects that reduce emissions or increase removals. While described in government materials as voluntary in character, the registry functions as a national reference point for MRV alignment and credibility of mitigation claims, especially when linked to carbon standards and public reporting.

Details

Jurisdictions
  • Argentina
Mandatory for

Not generally a universal legal obligation for all companies; obligations arise when participation is required by a program, standard, procurement rule, or financing covenant.

Exemptions

Companies can choose not to register, but then must manage higher credibility risk for project claims, and may face eligibility barriers in certain schemes.

What’s Required

1) Understand ReNaMi as an MRV alignment mechanism
The registry is designed to systematise information about mitigation projects in Argentina, including projects reducing anthropogenic emissions or increasing GHG removals.
For companies, this becomes a governance tool: if a company claims offsets or project-based reductions, the claim is more defensible if it aligns with the data structures and reference points the registry uses.

2) Maintain project-level documentation and traceability
Even when registration is not strictly mandatory, participation usually implies the ability to provide:

  • project boundaries, baselines, and additionality logic (as applicable)

  • monitoring plans, data sources, and QA/QC procedures.

  • verification documentation where third-party standards are used.

  • double-counting controls and ownership statements.

3) Reporting risk control: claims must match registry-compatible facts
Common corporate reporting risks include: overstating reductions, misrepresenting permanence, or double-counting between corporate and national accounting. Registry-aligned documentation reduces those risks by forcing structured disclosure.

4) Integration with carbon market strategies and public policies
Argentina’s carbon market strategy documents reference linkage between MRV systems and registries such as ReNaMi, reinforcing that registry data is part of the reporting ecosystem for markets and international transparency.

Important Deadlines

  • Date of adoption: 28 October 2021 (sanction date in official record).

  • Publication: 29 December 2021 (Boletín Oficial record).

  • Cadence: ongoing; project information updates depend on registry operational rules and applied standards.

Current Status

In force as a ministerial resolution creating the national mitigation project registry, supported by official guidance pages describing objectives and operation.

Penalties for Non-Compliance

Registry non-participation usually does not carry direct fines, but consequences can include:

  • loss of eligibility in programs that reference registry alignment.

  • reputational risk where corporate climate claims cannot be evidenced.

  • contractual remedies if buyers require registry-linked proof.

Examples of Known Violations

  • claims of emission reductions without baseline or monitoring evidence.

  • lack of clear ownership of mitigation outcomes (double claiming).

  • using non-comparable metrics across projects, preventing consolidation.

  • inability to provide third-party verification documentation when claimed.
