TNFD vs TCFD: How the Two Frameworks Relate

TNFD vs TCFD: How the Two Frameworks Relate

TNFD and TCFD are often mentioned together and just as often confused. They are related by design — one was built on the model of the other — but they cover different things and sit at very different stages of their lifecycle. This article explains how the two relate, why TCFD’s work has moved into the ISSB standards, and where nature reporting is heading.

The starting point: what each covers

The Task Force on Climate-related Financial Disclosures (TCFD) addressed climate. It gave the market a framework for disclosing climate-related risks and opportunities, built around four pillars — governance, strategy, risk management, and metrics and targets — and a set of recommended disclosures. It became the dominant global reference for climate reporting over the second half of the last decade.

The Taskforce on Nature-related Financial Disclosures (TNFD) addresses nature — biodiversity, ecosystems and a firm’s dependencies and impacts on the natural world. It deliberately adopted the same four-pillar structure as TCFD, so that a firm familiar with climate disclosure would find the nature framework recognisable. The relationship, in short: TNFD is to nature what TCFD was to climate, and it was built that way on purpose.

Why TCFD is spoken of in the past tense

Here is the point that causes most confusion. The TCFD has been disbanded. In 2023 the Financial Stability Board announced that the TCFD’s work was complete, because the newly-created International Sustainability Standards Board had issued IFRS S1 and IFRS S2, which fully incorporated the TCFD recommendations. The TCFD formally disbanded in October 2023, and the IFRS Foundation took over monitoring companies’ climate-reporting progress.

So TCFD is no longer a live, separately-maintained framework. Its substance lives on — entirely — inside IFRS S2, and a firm applying IFRS S1 and S2 meets the TCFD recommendations. When people refer to TCFD reporting today, they are really referring to a framework whose content has been absorbed into the ISSB standards.

The UK position: moving to UK SRS

For UK firms specifically, there is a further step. UK reporting has been anchored to TCFD through FCA listing rules and company law. The UK is now moving to its own endorsed versions of the ISSB standards — the UK Sustainability Reporting Standards (UK SRS S1 and S2), published in final form in early 2026. The FCA has consulted (in CP26/5) on replacing its TCFD-aligned listing rules with UK SRS alignment, with final rules expected in autumn 2026 and application for accounting periods beginning on or after 1 January 2027.

UK SRS S2 retains the familiar four-pillar climate structure but goes further than TCFD — more prescriptive on Scope 1, 2 and 3 emissions, scenario analysis and connectivity with the financial statements. In the interim, the existing TCFD-aligned rules remain in force, so firms are in a transitional period: reporting under the current regime while preparing for a more demanding successor.

Where nature reporting sits now

Nature reporting — TNFD’s territory — is at an earlier stage. It remains largely voluntary and market-led, and early adopters face real challenges around data availability and the quantification of nature-related risks. But the direction is set: the ISSB announced in late 2025 that it will undertake standard-setting on nature-related disclosures not already captured in IFRS S1 and S2, with options ranging from a dedicated standard to incremental additions. Both the EU’s CSRD and IFRS S1 already require disclosure of material nature-related risks and opportunities.

In other words, nature reporting looks today somewhat as climate reporting did a few years ago — voluntary, evolving, but heading toward a formal standard. The clear message from bodies like TNFD has been for firms to start now wherever they are, rather than wait for the standard to arrive.

What this means in practice

For a firm, the practical position is: climate disclosure is mandatory-and-consolidating — TCFD absorbed into IFRS S2, moving to UK SRS S2 from 2027 — while nature disclosure is voluntary-but-emerging, with TNFD shaping practice and an ISSB standard on the horizon. A firm building its sustainability reporting capability should treat the two as the same journey at different stages, and build a function that can handle climate rigorously now while getting ready for nature.

FD Capital recruits the finance and compliance professionals who own sustainability reporting and its governance, into regulated and listed firms.

Why the frameworks share a structure

The deliberate alignment of TNFD with TCFD’s four pillars was a strategic choice, and understanding why helps explain how they relate. When TNFD was designed, TCFD was already the established, widely-understood model for disclosing an environmental risk. Rather than invent a new structure, TNFD adopted the same governance-strategy-risk-metrics architecture so that firms and investors already fluent in climate disclosure could apply the same mental model to nature. The shared structure is a feature, not a coincidence: it lowers the barrier to nature reporting for anyone who has done climate reporting.

That is why the two are so often discussed together — not because they cover the same ground, but because they are built on the same frame and represent the same idea applied to two different environmental dimensions.

Climate and nature are connected, not separate

A further reason the frameworks belong together is that climate and nature risk are genuinely interlinked. Climate change drives nature loss, and healthy ecosystems buffer climate impacts; a firm’s dependencies often span both. Increasingly, the reporting world reflects this — IFRS S1 already requires disclosure of material sustainability risks including nature-related ones, and the ISSB’s move into nature standard-setting will bring the two closer still within a single reporting architecture. Firms that build climate and nature reporting as one connected capability, rather than two silos, are better positioned for where the standards are heading.

Practical guidance for firms

For a firm working out how to approach this, the sensible sequence follows the maturity of the two areas. Get climate reporting right first, because it is mandatory and consolidating — ensure the firm is meeting its current TCFD-aligned obligations and preparing for UK SRS S2 from 2027. Then build nature-reporting capability in parallel, starting now even though it is voluntary, because the data and governance take time to establish and a formal standard is coming. Treating the two as one journey at different stages, using the shared four-pillar structure, is the most efficient way through.

What each framework means for a finance function

For a finance or reporting function specifically, the practical demands differ between the two. Climate disclosure under IFRS S2 and UK SRS S2 is now a rigorous, quantified reporting exercise — emissions across all three scopes, scenario analysis, and connectivity with the financial statements — that sits squarely in finance territory and demands robust data and controls. Nature disclosure under TNFD is, for now, a more qualitative and exploratory exercise, focused on identifying dependencies and impacts where the data is often immature.

The trajectory, though, is toward nature reporting becoming as quantified and rigorous as climate reporting has become. A finance function building capability now should assume that nature will follow the same path climate has taken — from voluntary and narrative toward mandatory and quantified — and build data foundations that can support both.

The governance dimension

Both frameworks put governance in their first pillar for a reason: credible sustainability reporting depends on genuine board oversight, clear responsibility, and the integration of sustainability risk into the firm’s wider risk management. A firm that treats disclosure as a reporting output produced by a corner of finance, without board engagement or integration into risk management, will struggle to meet the governance expectations of either framework. The strongest firms embed sustainability governance into their existing structures rather than bolting it on, which is also what the incoming UK SRS regime will expect.
