Sustainability & Carbon Compliance
Jurisdictions with ISSB adoption as of January 2026
GHG emissions disclosure required under IFRS S2
Governance, Strategy, Risk Management, Metrics & Targets
The ISSB standards represent the global baseline for investor-focused sustainability disclosure. For supply chain and compliance teams, the primary obligation is producing structured, comparable data on sustainability-related risks and opportunities—with climate disclosure under IFRS S2 carrying the most prescriptive requirements, including mandatory Scope 1, 2, and 3 GHG emissions reporting.
As of January 2026, 21 jurisdictions have adopted ISSB standards on a voluntary or mandatory basis, with mandatory reporting now live in Brazil, Chile, Mexico, Qatar, Australia, Malaysia, and Hong Kong, among others. The ISSB has also confirmed it will publish a nature-related disclosures exposure draft by October 2026, expanding the scope of sustainability reporting beyond climate. IOSCO's endorsement signals adoption across the 130 jurisdictions it represents.
ISSB compliance requires value-chain-level data—Scope 3 emissions from suppliers, climate risk exposure by asset, and industry-specific metrics per SASB Appendix B. When jurisdictions mandate reporting, your entire supplier base requires sustainability data collection and validation.

Suppliers in the value chain of reporting entities required to provide Scope 3 and ESG data
Key Thresholds
IFRS S2 requires disclosure of value chain emissions across all material Scope 3 categories. For most manufacturers, Category 1—purchased goods and services—dominates the footprint. But supplier-level emissions data is fragmented across spreadsheets, PDFs, and email attachments. CDP reports cover a fraction of your supply base. The rest requires direct engagement with hundreds of suppliers who have never measured their carbon output.
Your Australian subsidiary reports under AASB S2 for FY2025. Brazilian operations face mandatory CBPS reporting from January 2026. Hong Kong listed entities shifted to mandatory IFRS S2 in 2026. Each jurisdiction layers its own phasing, scope, and assurance requirements onto the same ISSB baseline. Without a centralized compliance data backbone, your teams produce three parallel workstreams to satisfy one set of standards.
IFRS S2 Appendix B pulls industry-specific metrics from SASB across 70+ industries. An electronics manufacturer must disclose product lifecycle environmental impacts. An energy company must report reserves sensitivity to carbon pricing. A chemical manufacturer must disclose hazardous waste metrics. These SASB-derived requirements sit buried in appendices—and mapping them against your operations requires specialized substance reporting solutions that most ERP systems do not provide.
Jurisdictions adopting ISSB standards are layering assurance requirements on sustainability disclosures. Limited assurance in Year 1, reasonable assurance by Year 3. Your data must withstand auditor scrutiny—not just at the consolidated level, but across suppliers, facilities, and business units. Manual ESG data collection through email campaigns and spreadsheet aggregation cannot produce the audit trail that assurance providers demand.

Frequently Asked Questions
What companies are subject to ISSB reporting obligations?
Any company in a jurisdiction that has adopted IFRS S1 and S2 into national law or regulation must comply. As of 2026, this includes listed and publicly accountable entities in Brazil, Chile, Mexico, Australia, Malaysia, Hong Kong, and a growing number of other markets. Even companies in non-mandating jurisdictions face indirect pressure when customers, investors, or capital market counterparts require ISSB-aligned disclosures. Certivo's centralized compliance data backbone helps organizations track which entities fall within scope across multiple jurisdictions simultaneously.
How does ISSB compliance affect manufacturers that are not publicly listed?
Non-listed manufacturers are increasingly drawn into ISSB compliance through their customers' Scope 3 reporting obligations. When a listed company must disclose value chain emissions, it requests activity data from every supplier in its chain. CORA automates both sides of this exchange—collecting data from your suppliers and generating response packages for your customers—through automated supplier data collection and portals that handle the volume without adding headcount.
What is the relationship between ISSB, TCFD, and CSRD?
ISSB fully incorporates and supersedes TCFD—the TCFD disbanded in 2023 after IFRS S1 and S2 were issued. Companies already reporting under TCFD meet the core ISSB four-pillar structure. CSRD operates under EU double materiality, while ISSB uses financial materiality. Both share significant overlap on climate disclosure. Certivo validates one supplier submission against ISSB, CSRD, and related frameworks through multi-framework compliance monitoring, eliminating duplicate data collection.
How does Certivo handle Scope 3 emissions data collection from suppliers?
Certivo launches targeted campaigns through centralized supplier self-service portals, requesting emissions factors, energy consumption, and activity data from suppliers in their preferred format and language. CORA parses every response—CDP disclosures, PDF reports, Excel files, freeform declarations—extracting metrics to the precision required for GHG Protocol-aligned Scope 3 calculations. Anomaly detection flags inconsistent data before it reaches your consolidated disclosure, ensuring audit-ready quality at the point of collection.
What happens when new jurisdictions adopt ISSB standards?
Certivo monitors jurisdictional adoption status through regulatory intelligence and horizon scanning. When a new market mandates ISSB reporting—or updates phasing, assurance, or scope requirements—Certivo reassesses your entity portfolio, identifies newly in-scope operations, and triggers the appropriate data collection and disclosure workflows automatically, giving compliance teams lead time to prepare rather than scramble at deadline.
