IFRS S1 / IFRS S2
ISSB Sustainability Disclosure Standards — General and Climate-related Disclosures
Standard Introduction

Use this page to review the official documentation, current status, and the certification or assessment bodies most commonly associated with IFRS S1 / IFRS S2.
Investor-grade disclosure baseline
IFRS S1 sets the general architecture for sustainability-related financial disclosures, while IFRS S2 adds climate-specific metrics, governance, risk management, strategy, and targets.
Interoperability focus
Companies use ISSB as a global baseline when reconciling CSRD/ESRS, national climate disclosure rules, and voluntary TCFD-style reporting.
Financial materiality lens
The standards focus on sustainability risks and opportunities that could reasonably affect enterprise value, cash flows, finance access, or cost of capital.
list_alt Implementation Focus Areas
- Governance over sustainability risks and opportunities
- Materiality assessment tied to investor decision-making
- Climate scenario analysis and transition planning
- Scope 1, Scope 2, and relevant Scope 3 greenhouse gas emissions
- Cross-functional controls over source data
- Connectivity between sustainability and financial statements
Who Needs to Comply?
Public companies, financial institutions, large private groups, and multinational suppliers preparing sustainability disclosures for investors or jurisdictions adopting ISSB-aligned rules. Also relevant for companies aligning CSRD, TCFD, and local climate disclosure workstreams.
Key Requirements
Governance and accountability
Define board and management oversight for sustainability-related risks and opportunities, including who reviews disclosures and how sustainability topics enter enterprise risk management.
Materiality and scope
Identify sustainability matters that could affect enterprise value. Document judgments, boundary decisions, value-chain assumptions, and why topics were included or excluded.
Climate metrics and targets
For IFRS S2, disclose climate-related metrics, greenhouse gas emissions, transition risks, physical risks, and progress against targets where applicable.
Data controls and assurance readiness
Build auditable controls over emissions, supplier, financial, and operational data. Reconcile sustainability figures to finance-owned systems where possible.
Implementation Roadmap
Define ISSB sustainability disclosure scope
Identify the products, services, systems, entities, jurisdictions, teams, vendors, and stakeholders covered by IFRS S1 / IFRS S2. Confirm owners, boundaries, applicable obligations, documentation, and evidence expectations for sustainability-related risks and opportunities, climate disclosures, governance, strategy, risk management, metrics, targets, financial effects, scenario analysis, transition plans, and connected financial reporting.
Assess obligations and gaps
Compare current practices with the expected ISSB sustainability disclosure approach. Review disclosure scoping, materiality judgment, climate-risk assessment, data governance, methodology control, emissions data, scenario assumptions, financial statement connectivity, management review, and board approval, then prioritize gaps by legal exposure, financial reporting impact, security or privacy impact, customer commitments, operational dependency, and audit readiness.
Implement controls and evidence
Deploy required procedures, technical controls, review gates, training, supplier workflows, reporting paths, and operational records. Maintain ISSB disclosure maps, materiality assessments, climate-risk files, metrics workpapers, emissions data, scenario analysis, transition-plan records, financial linkage analysis, approvals, and assurance evidence as traceable evidence.
Review, report, and improve
Run management reviews, internal checks, independent assessments where applicable, corrective actions, and change reviews. Refresh the program when products, vendors, laws, incidents, assurance expectations, or stakeholder needs change.

Penalties & Enforcement
IFRS S1/S2 do not directly impose penalties by themselves. Enforcement comes through jurisdictions that adopt or reference ISSB standards, securities regulators, listing rules, audit/assurance expectations, and investor or lender requirements.
Frequently Asked Questions
Who needs IFRS S1 / IFRS S2?
expand_more
IFRS S1 / IFRS S2 is most relevant to entities preparing investor-focused sustainability and climate-related financial disclosures under ISSB-aligned jurisdictional requirements or voluntary adoption. The exact scope depends on products, services, jurisdictions, customer commitments, assurance requirements, and the organization's role in the relevant ecosystem.
Is IFRS S1 / IFRS S2 certifiable?
expand_more
IFRS S1 and S2 are disclosure standards, not certifications. Assurance requirements depend on the adopting jurisdiction, exchange, or investor mandate.
What should implementation focus on first?
expand_more
Start by defining scope, obligations, accountable owners, and the evidence expected by regulators, auditors, customers, or governance bodies. Then perform a gap assessment against current controls and prioritize remediation by risk and deadline.
What evidence is useful for IFRS S1 / IFRS S2?
expand_more
Useful evidence includes ISSB disclosure maps, materiality assessments, climate-risk files, metrics workpapers, emissions data, scenario analysis, transition-plan records, financial linkage analysis, approvals, and assurance evidence. Evidence should be version-controlled, attributable to owners, linked to obligations and controls, and retained for the required review or audit period.
How often should the program be reviewed?
expand_more
Review it at planned intervals and whenever laws, products, vendors, incidents, customer commitments, reporting cycles, or assurance expectations change. Higher-risk obligations should have more frequent monitoring and management reporting.
