TCFD status today
The Task Force on Climate-related Financial Disclosures (TCFD) was established in December 2015 by the Financial Stability Board. Final recommendations were published in October 20173.
The TCFD was formally disbanded in October 20234 following the IFRS Foundation's establishment of the International Sustainability Standards Board and publication of IFRS S16 and IFRS S25 in June 2023. Responsibility for monitoring TCFD-aligned disclosure passed to the IFRS Foundation from January 20244.
In the UK, TCFD-aligned disclosure has been required for premium-listed companies under the previous UK Listing Rules2. UK SRS S21 is the regulatory successor — proposed mandatory from 1 January 2027 under FCA CP26/52 for listed companies population.
What survives: the four pillars
TCFD established a four pillars3: Governance, Strategy, Risk Management, and Metrics & Targets. This structure is preserved in IFRS S25 and consequently in S2 climate standard1.
For companies that have built TCFD reporting capability, the structural continuity is meaningful — board oversight, scenario analysis processes, risk identification frameworks, and GHG metrics infrastructure all carry over. The pillars are not new.
What changes is the depth and rigour required within each pillar. climate-related disclosures doesn't reorganise climate disclosure; it substantially raises the bar within the existing organisation.
Five substantive enhancements
UK SRS substantially enhances TCFD-aligned reporting in five specific areas. Each is a step-change in disclosure expectations, not an incremental adjustment. The signature visual above shows the five at a glance; this section examines each in detail.
1 — Quantitative financial effects
TCFD3 described quantitative disclosure of climate-related financial effects as desirable but did not mandate it. Most TCFD-aligned disclosures under the previous UK regime contained qualitative narrative about climate impacts on strategy, with limited quantification.
SRS S2 paragraphs 18-211 require disclosure of current and anticipated effects of climate-related risks and opportunities on financial position, financial performance, and cash flows for the reporting period and short, medium, and long term. Quantitative disclosure is required1, with qualitative-only relief available only where measurement uncertainty is genuinely high.
The practical effect: where a TCFD disclosure might have said "physical climate risks could affect coastal operations," UK SRS S2 expects quantified disclosure of the asset values exposed, the time horizons over which effects could materialise, and the financial impact under specified scenarios.
2 — Financial-statement connectivity
TCFD treated climate disclosures and financial statements as separate documents. There was no requirement to explain how climate-related risks and opportunities connected to the recognition and measurement of assets, liabilities, provisions, and forward-looking estimates in the financial statements.
UK SRS S11 establishes the connectivity principle as a core requirement. Companies must explain how sustainability-related risks and opportunities relate to information in their financial statements — carrying amounts of assets and liabilities, recognition and measurement of provisions, and assumptions used in forward-looking estimates1.
This applies under UK SRS S2 climate disclosures through the foundational connectivity principle in S1 — S2 cannot be applied without S1's foundational elements1.
3 — Scenario analysis required, not recommended
TCFD recommended scenario analysis3 with rigour appropriate to circumstances. Many TCFD-aligned disclosures under the previous UK regime relied on narrative scenarios — describing potential climate futures without quantified analysis of business model resilience.
UK SRS S2 paragraph 221 makes scenario analysis a hard requirement1. The standard requires rigour commensurate with entity exposure — entities with greater climate exposure must use more technically sophisticated approaches. At least one scenario must align with the latest international agreement on climate change1.
Common frameworks supporting paragraph 22 compliance include NGFS climate scenarios8 and IEA Net Zero by 20501. Entities with high climate exposure can no longer rely on qualitative narrative scenarios — quantified analysis with explicit assumptions about climate policy, macroeconomic trends, energy use and mix, and technology developments is expected1.
4 — Scope 3 emissions required across all 15 categories
TCFD3 treated Scope 3 emissions as a material-based recommendation. Most TCFD-aligned disclosures focused on Scope 1 and Scope 2, with Scope 3 reporting concentrated on the most material categories for the industry concerned.
UK SRS S2 paragraph 29(a)1 requires Scope 3 emissions across the 15 categories of the GHG Protocol Corporate Value Chain Standard7, with the entity disclosing which categories are included in its measure1. Materiality drives which categories require detailed disclosure, but the default expectation is comprehensive consideration of all 15.
The first-year transition relief1 defers Scope 3 disclosure to year two, and FCA CP26/52 adds an optional additional one-year deferral on top. The practical effect: Scope 3 becomes comply-or-explain across all 15 categories from accounting periods beginning 1 January 20282.
5 — Financed emissions for financial institutions
TCFD3 did not specify financed emissions disclosure requirements for financial institutions. Most TCFD-aligned disclosures from banks, asset managers, and insurers focused on operational emissions (Scope 1 and 2) with limited disclosure of portfolio climate impacts.
UK SRS S2 imposes detailed financed emissions requirements on financial institutions1. Paragraph B59 applies to asset management, commercial banking, and insurance activities1. UK paragraph B59A1 allows a different reporting period from the financial statements where alignment is impracticable, with disclosure of the reasons.
The practical effect: UK financial institutions must disclose absolute gross financed emissions disaggregated by Scope 1, 2, and 31. This represents a step-change in portfolio climate risk transparency compared to TCFD-aligned disclosure.
Transition plans: where UK SRS lands
UK SRS S2 paragraph 14(a)(iii)1 requires disclosure of any climate-related transition plan, including key assumptions used and dependencies on which the plan relies. The "any" qualifier is significant — transition plans are not mandated by UK SRS S21.
FCA CP26/52 does not propose to mandate transition plans separately. The approach differs from the European Corporate Sustainability Reporting Directive, which includes specific transition plan requirements. Under UK SRS, companies must disclose transition plans if they exist, but are not required to have one.
For TCFD-aligned companies that have developed transition plans, the disclosure requirements under paragraph 14(a)(iii) provide clear guidance on what to include. For those that haven't, UK SRS does not compel transition plan development.
Migration guidance for TCFD reporters
Companies with established TCFD reporting should focus enhancement efforts on the five areas where UK SRS S2 raises the bar substantially. The four-pillar structure provides continuity; the challenge is depth, not reorganisation.
Priority areas for TCFD reporters preparing for UK SRS compliance1: quantify climate-related financial effects per paragraphs 18-21, establish financial statement connectivity per S1 requirements, upgrade scenario analysis to meet paragraph 22 hard requirements, prepare for comprehensive Scope 3 disclosure across all 15 categories, and for financial institutions, develop financed emissions measurement and disclosure capability.
