A New Era for Climate Disclosure
The Financial Stability Board's Task Force on Climate-related Financial Disclosures (TCFD) has completed its mission, with monitoring responsibilities transferred to the ISSB. For the thousands of companies that have built their climate reporting around the TCFD pillars, this transition raises important questions about continuity and change.
What Stays the Same
The good news for companies already reporting under TCFD is that IFRS S2 (Climate-related Disclosures) is built on TCFD foundations. The four-pillar structure — Governance, Strategy, Risk Management, and Metrics & Targets — remains intact. If your organization has invested in TCFD-aligned reporting, that work directly feeds into ISSB compliance.
What Changes
IFRS S2 goes further than TCFD in several important areas. Companies must now provide industry-specific disclosures derived from SASB standards, not just the general TCFD recommendations. Scope 3 greenhouse gas emissions disclosure is required (TCFD recommended it but did not mandate it). Climate resilience assessments must use scenario analysis, and the connection between climate risks and financial statements must be explicitly demonstrated.
Transition Planning
A significant addition in ISSB is the requirement to disclose transition plans — how the organization intends to address climate-related risks and pursue climate-related opportunities. This includes decarbonization targets, capital allocation plans, and the assumptions underlying the transition strategy.
Practical Steps
Companies should audit their current TCFD disclosures against IFRS S2 requirements to identify gaps. The most common gaps include insufficient Scope 3 emissions data, lack of industry-specific metrics, and weak connections between climate scenarios and financial planning. Investing in integrated climate and financial data systems will be essential for meeting the enhanced requirements efficiently.
