TCFD vs UK SRS: what actually changes

The same architecture, raised to a standard

The Task Force on Climate-related Financial Disclosures was set up by the Financial Stability Board to make climate risk visible in mainstream financial reporting.

Its final recommendations, published in October 2017, organised climate disclosure around four pillars: governance, strategy, risk management, and metrics and targets^[1].

In 2023 the FSB concluded the Task Force had fulfilled its remit and asked the IFRS Foundation to take over monitoring of climate-related disclosures; the Task Force was disbanded in October 2023^[2].

The framework did not disappear — it was absorbed. The ISSB built IFRS S2 on the four TCFD pillars and fully incorporated the recommendations, then went further^[2].

The UK has adopted that standard as UK SRS S2. So the shift from TCFD to UK SRS is less a new language than a stricter dialect of the one reporters already speak.

What TCFD was, and why it ended

TCFD was a set of voluntary recommendations rather than a standard. It told organisations what to disclose about climate risk but left a great deal of latitude on how — and whether — to quantify it^[1].

That flexibility drove rapid, voluntary adoption, and the UK made TCFD-aligned reporting a Listing Rule requirement for premium-listed issuers from 2021, on a comply-or-explain basis^[5].

But voluntary recommendations cannot deliver comparable, decision-useful data at scale. The ISSB was created to convert the patchwork of voluntary frameworks into a single global baseline, and IFRS S1 and S2 were issued in June 2023^[3].

With the baseline in place, the Task Force’s monitoring role passed to the IFRS Foundation, which now maintains the relevant materials^[2].

TCFD vs UK SRS, area by area

The two frameworks share an architecture but diverge sharply on rigour.

The table below maps the main areas a reporter has to revisit.

The five enhancements that matter most

Five changes account for most of the additional work in moving from TCFD to UK SRS S2.

Quantified financial effects. UK SRS S2 requires disclosure of the anticipated financial effects of material climate risks and opportunities, not just a narrative description of impact^[3].

Scenario analysis as a hard requirement. Where TCFD recommended scenario analysis, UK SRS S2 makes climate-resilience scenario analysis a requirement^[3].

Full Scope 3. Scope 3 emissions must be reported across all 15 GHG Protocol value-chain categories, the part of the footprint most often left out under TCFD^[4].

Financial-statement connectivity. The climate disclosures must connect to the figures in the financial statements, so the numbers are consistent rather than sitting in a separate narrative^[3].

Financed emissions. Financial institutions must disclose financed emissions under Scope 3 Category 15 — a demand that barely registered in many TCFD reports^[3][4].

We unpack the value-chain work in detail in our Scope 3 reporting guide.

How the FCA is retiring the TCFD-aligned Listing Rules

For UK listed companies, the legal mechanism that makes the switch real is FCA CP26/5, published on 30 January 2026^[5].

It proposes to replace the existing TCFD-aligned Listing Rules with rules requiring in-scope listed companies to report against UK SRS S2 for accounting periods beginning on or after 1 January 2027^[5].

Under the proposals, S2 climate reporting becomes mandatory, while Scope 3 emissions and the wider non-climate UK SRS requirements apply on a comply-or-explain basis with transitional relief^[5].

The consultation closed on 20 March 2026, and the FCA expects to publish a Policy Statement in autumn 2026^[5].
