What’s Required
1) Produce a sustainability-related financial information report as part of the annual financial reporting package
Resolution 5,185 modifies the CMN framework that governs the preparation and disclosure of financial statements by financial institutions, adding a new chapter specifically on sustainability-related financial information reporting. In practical compliance terms, this creates a regulated deliverable (a report) that must be prepared with the same discipline expected for financial reporting: defined scope, accountability, evidence trails, and consistency.
2) Align disclosures to IFRS S1 and IFRS S2 concepts and structure (general sustainability and climate)
The Central Bank communication explains that institutions will disclose sustainability-related financial information according to international standards, with climate-related disclosures embedded as part of that structure. Even before full mandatory adoption dates apply to all institutions, compliance programs should adopt the IFRS S1/S2 logic:
identification of sustainability and climate-related risks and opportunities that could reasonably affect cash flows, access to finance, or cost of capital.
governance and risk management disclosures (how the board and management oversee the topics).
strategy and resilience disclosures (how the business model and strategy respond to climate and sustainability risks).
metrics and targets used to manage those risks, including data sources and limitations.
The key compliance shift is that sustainability disclosure is treated as financially relevant information with an investor-decision orientation, not narrative ESG reporting.
3) Build reporting governance comparable to financial reporting governance
Because the report is linked to annual financial statements, institutions should implement controls that mirror financial reporting controls:
formal assignment of accountability (CFO/finance leadership plus sustainability risk leadership).
board-level oversight and sign-off workflow.
documented methodologies for metrics, scenario inputs, and boundary definitions.
internal control testing and audit committee challenge.
retention of evidence sufficient to support audit assurance.
A practical model is to treat the sustainability report as another regulated reporting stream inside the “financial reporting perimeter,” subject to internal audit and risk functions.
4) Integrate data pipelines across risk, finance, credit, treasury, and operations
Financial institutions often hold sustainability data in fragmented systems: credit risk (counterparty exposures), market risk, operational risk, ESG questionnaires, and climate analytics vendors. Compliance readiness requires an integrated reporting architecture:
a data dictionary defining each metric, its source system, and ownership.
reconciliation rules to ensure consistency between sustainability disclosures and financial statements (e.g., concentration of exposure in carbon-intensive sectors, impairment sensitivities, provisioning assumptions)
procedures for model governance where scenario analysis or climate stress testing is used.
documentation of estimation uncertainty and limitations.
This is essential because the rule aims for decision-useful information, and inconsistencies between disclosures and financial statements create supervisory red flags.
5) Assurance and auditability expectations
The Central Bank framing signals an expectation of reliable, comparable information. Compliance programs should assume that assurance expectations will increase over time: third-party auditability depends on evidence, controls, and stable methodologies. Institutions that treat this as a “communications” product risk later remediation costs and potential supervisory findings when assurance becomes more stringent.
6) Group structure and consolidation discipline
Financial institutions operating as conglomerates should prepare a consolidated reporting approach aligned with their consolidated financial statements. This requires:
defining which entities are in scope
ensuring consistent methods across subsidiaries
aligning governance and controls across the group
handling cross-entity exposures and financed emissions logic consistently (where used)
Important Deadlines
Date of adoption: 21 November 2024.
Entry into force: Resolution 5,185 enters into force on 1 January 2025, with phased mandatory reporting timelines described by the Central Bank.
Phased compliance: the Central Bank indicates mandatory reporting starting in 2026 for larger institutions, with later phases for others. Institutions should treat these as hard project timelines for systems, controls, and assurance readiness.
Current Status
In force as a binding CMN norm that modifies the consolidated financial reporting rules and creates a sustainability reporting chapter and deliverable for regulated institutions.
Penalties for Non-Compliance
Non-compliance can trigger supervisory actions typical of prudential reporting failures:
formal findings and remediation plans
increased supervisory intensity and reporting requirements
potential administrative sanctions under the financial regulation framework, where failures are persistent or misleading
In practice, the highest risk is supervisory credibility damage and constrained market access (funding and counterparties) if disclosures are seen as unreliable.
Examples of Known Violations
Typical failure modes in sustainability financial reporting include:
governance gap: no accountable owner; disclosures produced without internal control testing
inconsistent numbers: exposures and risk concentrations disclosed but not reconcilable with financial statements or Pillar/other regulatory reports
unsupported estimates: scenario outputs and sensitivity claims without model documentation and validation
selective disclosure: reporting only favourable metrics while omitting material risks or limitations
assurance failure: inability to produce evidence for third-party verification
