TCFD explained: what it is, who it applies to, and what comes next

The Task Force on Climate-related Financial Disclosures (TCFD) changed climate reporting by moving climate risk from sustainability reports into financial reporting. This guide explains what TCFD means, who it applies to, how the four pillars work in practice, and why it still matters as the UK moves toward UK Sustainability Reporting Standards.

This guide is for general information only. It is not legal, accounting, regulatory or investment advice.

TCFD is no longer an active task force. It completed its work and disbanded in 2023. That does not make it irrelevant. If anything, it shows how influential the framework became.

TCFD matters because it changed the location of the climate conversation. Before TCFD, climate information often sat in sustainability reports, separate from the financial report, written in broad language about responsibility, ambition and stakeholder engagement. TCFD pushed the issue into a harder question: what does climate change mean for the financial resilience of the business?

That shift is why TCFD is still worth understanding in 2026. Its four pillars, governance, strategy, risk management, and metrics and targets, are now built into International Financial Reporting Standard S2 (IFRS S2), the global climate disclosure standard developed by the International Sustainability Standards Board (ISSB) within the International Financial Reporting Standards (IFRS) Foundation. The UK government published UK Sustainability Reporting Standards (UK SRS) S1 and S2 in February 2026, based on IFRS (International Financial Reporting Standards) Sustainability Disclosure Standards. The Financial Conduct Authority (FCA) is consulting on replacing existing TCFD-aligned listing rules with UK SRS-based requirements for in-scope listed companies.

In other words, TCFD is not disappearing so much as being absorbed. The acronym may become less visible, but the architecture remains.

Quick answer

What TCFD was built to solve

TCFD was established by the Financial Stability Board in 2015 and chaired by Michael Bloomberg. The task force brought together banks, insurers, asset managers and companies to solve a specific problem: investors could not compare companies' exposure to climate risk because companies were not reporting that risk consistently.

Its final recommendations, published in June 2017, were not written as a broad environmental manifesto. They were written for capital markets. The point was to help investors, lenders and insurers understand how climate change could affect corporate cash flows, asset values, liabilities, costs, strategy and resilience.

That distinction matters. TCFD is not the same thing as a net zero plan. It is not a carbon-reduction target. It is not a marketing claim. It is a way of asking whether a company understands the financial consequences of physical climate change and the transition to a lower-carbon economy.

The task force completed its remit and disbanded in 2023. From 2024, responsibility for monitoring progress on climate-related disclosures moved to the same foundation that houses the ISSB. That institutional handover is one reason the UK is now moving from TCFD-aligned rules toward UK SRS.

Why climate risk became financial risk

The core insight behind TCFD is simple: climate risk is not only an environmental issue. It is a financial issue.

Physical climate risks come from the direct effects of a changing climate. They include flooding, heat, drought, storms, sea-level rise, water stress and supply-chain disruption. A property company may face rising flood risk across part of its portfolio. A food producer may face crop disruption. A manufacturer may face higher cooling costs, heat-related shutdowns or supplier failures.

Transition risks come from the shift toward a lower-carbon economy. These include carbon pricing, policy changes, changing customer demand, litigation, new reporting rules, changes in technology and the risk that high-emissions assets become less valuable. A company with gas-heavy operations may face rising costs. A car manufacturer may face faster-than-expected shifts in demand. A bank may discover that parts of its loan book are exposed to sectors that need expensive transition plans.

TCFD was built because these risks were often discussed in broad sustainability language, but not always connected to the balance sheet, income statement or capital allocation. Investors did not only need to know whether a company cared about climate change. They needed to know whether climate change could affect revenue, margins, asset values, financing costs and long-term strategy.

That is the difference between climate disclosure as public relations and climate disclosure as financial reporting.

A simple example: one company, four questions

Take a fictional UK manufacturer, Riverside Components. It makes precision parts for industrial customers, operates two UK factories, buys energy under multi-year contracts and exports into Europe.

Under a weak sustainability report, Riverside might say that it is committed to reducing emissions, supporting net zero and improving energy efficiency. That may sound positive, but it does not tell investors much about financial risk.

Under a TCFD-style disclosure, Riverside has to answer harder questions.

Who is responsible for climate risk at board level? What happens if a key factory sits in an area with rising flood exposure? What happens if electricity prices and carbon costs rise faster than expected? Does the company rely on customers who are themselves exposed to carbon regulation? Which emissions, energy, asset-exposure or capital-expenditure metrics is management using to track the risk?

That is why TCFD became influential. It turns a broad climate story into a structured financial-risk conversation.

Who has to report in the UK?

The UK has several overlapping TCFD-aligned reporting regimes. The important point is that there is no single universal rule that applies identically to every business.

Listed companies

The FCA introduced climate-related disclosure rules for premium listed companies for financial years beginning on or after 1 January 2021. Requirements were later extended to standard listed commercial companies for financial years beginning on or after 1 January 2022.

Those current listing rules are aligned with TCFD. The FCA is now consulting, through CP26/5, on replacing the existing TCFD-aligned listing rules with requirements linked to UK SRS. The FCA says the scope of its proposals broadly aligns with the existing TCFD-based rules and that it aims to finalise the rules and publish a policy statement in autumn 2026, subject to final UK SRS.

For accounting periods beginning before 1 January 2027, the FCA proposes transitional provisions that would allow companies to continue using the existing TCFD-aligned rules and guidance, or voluntarily move early to the proposed UK SRS-related requirements. For accounting periods beginning on or after 1 January 2027, in-scope listed companies would move into the proposed UK SRS framework if the FCA finalises the rules.

This is why the 2027 date matters, but it should not be treated as a blanket statement that UK SRS automatically applies to every UK company from that date.

Large UK companies and limited liability partnerships

The Companies (Strategic Report) (Climate-related Financial Disclosure) Regulations 2022 apply to certain UK companies for financial years beginning on or after 6 April 2022. The regulations sit in the Companies Act 2006 reporting framework and require climate-related financial disclosures in the strategic report.

The scope includes:

• UK companies already required to produce a non-financial information statement, if they have more than 500 employees and have transferable securities admitted to trading on a UK regulated market, or are banking or insurance companies.
• UK registered companies with securities admitted to the Alternative Investment Market of the London Stock Exchange and more than 500 employees.
• UK registered companies outside those categories with more than 500 employees and turnover of more than GBP 500 million.

Limited liability partnerships (LLPs) have parallel climate-related reporting requirements under separate LLP regulations.

The key correction is that the large unquoted company threshold is not a balance-sheet test. It is more than 500 employees and turnover of more than GBP 500 million.

Asset managers, life insurers and regulated pension providers

FCA Policy Statement PS21/24 introduced TCFD-aligned disclosure rules for asset managers, life insurers and FCA-regulated pension providers.

The rules require entity-level and product-level disclosures, subject to thresholds. Larger firms came into scope first. Asset managers and asset owners above GBP 50 billion in assets were required to publish their first reports in 2023, while firms above GBP 5 billion came into scope for reports in 2024. Firms below GBP 5 billion are generally outside the regime for now.

These rules matter because they connect TCFD not only to corporate reporting, but also to investment products. A fund manager is expected to explain climate-related risks and metrics at firm level and product level, so clients can understand how climate risk is considered across portfolios.

Companies outside formal scope

Smaller companies may not be legally required to publish TCFD-aligned disclosures. That does not mean TCFD is irrelevant to them.

Banks, investors, large customers, insurers and procurement teams often ask climate-risk questions using TCFD language. A supplier may be asked who owns climate risk internally. A borrower may be asked whether it has assessed physical risk to property or operations. A private business preparing for sale may be asked how climate regulation affects future earnings.

The practical boundary of TCFD is therefore wider than the legal boundary. Many businesses encounter it through finance, insurance, procurement and due diligence long before they are formally in scope.

The four pillars, without the jargon

TCFD is built around four pillars: governance, strategy, risk management, and metrics and targets. The pillars are sometimes presented as a checklist. That is understandable, but not enough. They are better understood as a chain of accountability.

Governance asks who is responsible. Strategy asks what climate change means for the business model. Risk management asks how the company identifies and manages the risk. Metrics and targets ask what data the company uses to track it.

Governance: who owns the risk?

Governance is where many disclosures sound polished but weak. A company may say that the board oversees sustainability, or that climate matters are reviewed as part of environmental, social and governance (ESG) reporting. That is not the same as showing climate-risk governance.

For Riverside Components, the useful question is not whether the board supports sustainability. It is whether the board knows which climate risks could affect the company, who reports those risks, how often they are reviewed and what decisions they influence.

A stronger disclosure might say that the audit and risk committee reviews climate-related financial risk twice a year, that the finance director owns climate-risk reporting, that material risks are escalated through the enterprise risk register, and that capital expenditure decisions include energy-price and carbon-cost assumptions.

The difference is evidence. TCFD governance is not about sentiment. It is about whether responsibility is real enough to appear in committee mandates, board papers, management reporting and decision-making.

Strategy: what changes if the world changes?

The strategy pillar is where TCFD becomes more than a risk register. It asks how climate-related risks and opportunities could affect the business model, strategy and financial planning over different time horizons.

For Riverside, strategy might involve several questions. If customers in Europe begin demanding lower-carbon supply chains, does Riverside have the data to respond? If energy costs rise, does its margin profile change? If one factory is exposed to flood risk, does the company need resilience investment or alternative production capacity? If customers move toward lower-carbon products, is there a revenue opportunity?

The hardest part is scenario analysis. TCFD asks companies to assess resilience under different plausible futures, including lower-warming transition scenarios and higher-warming physical-risk scenarios. This does not mean predicting the future with false precision. It means testing whether the current strategy still works under credible climate and policy conditions.

Weak scenario analysis describes a 1.5C or 2C world in generic terms. Stronger scenario analysis connects the scenario to the company's own revenue, costs, assets, supply chain and capital needs.

Risk management: how is climate risk handled?

The risk management pillar asks how climate-related risks are identified, assessed and managed, and how that process fits into existing risk management.

This integration point matters. Climate risk should not live only in a sustainability spreadsheet. If it can affect operations, insurance, credit, capital spending, supply-chain resilience or customer demand, it belongs in the same risk-management machinery as other material business risks.

For Riverside, flood exposure may sit with operations. Energy-price risk may sit with finance. Supplier resilience may sit with procurement. The practical test is whether climate risk changes decisions: budgets, insurance reviews, capital allocation, supplier assessment or board discussion.

Metrics and targets: what data proves the story?

The final pillar asks what data the company uses to track climate-related risks and opportunities. Greenhouse gas emissions are part of this, but not the whole of it.

TCFD expects relevant metrics and targets, including emissions where material. In many UK TCFD-aligned regimes, Scope 1 and Scope 2 greenhouse gas emissions are the baseline. Scope 3 emissions depend on the regime, company type and materiality. The FCA's CP26/5 proposes that in-scope listed companies should report UK SRS S2 climate disclosures primarily on a mandatory basis, but with Scope 3 emissions continuing on a comply-or-explain basis, supported by transitional relief.

For Riverside, useful metrics might include Scope 1 fuel use, Scope 2 electricity emissions, energy intensity per unit of production, flood-exposed assets, proportion of revenue from customers with climate-related procurement requirements, and capital expenditure assigned to resilience or energy efficiency.

The key is connection. Metrics should not sit in isolation. They should connect back to the risks identified in strategy and the management process described under risk management. A standalone emissions number tells readers something. A metric tied to a business risk tells them much more.

TCFD vs ISSB vs UK SRS vs CSRD (Corporate Sustainability Reporting Directive)

Climate reporting is now crowded with acronyms. The useful way to separate them is to ask what each one is trying to do.

The biggest conceptual difference is materiality. TCFD, IFRS S2 and UK SRS S2 focus on sustainability-related information that could affect a company's prospects and is useful to investors. The Corporate Sustainability Reporting Directive (CSRD) uses double materiality, which asks both what affects the company financially and what impact the company has on people and the environment.

That makes CSRD broader. A company inside CSRD scope needs to think beyond investor-facing financial risk. A UK company primarily dealing with TCFD and UK SRS is still focused on financially material climate and sustainability information, although expectations are becoming more detailed.

TCFD is also separate from the international climate-policy architecture built around the Paris Agreement and the United Nations Framework Convention on Climate Change (UNFCCC). For that policy background, see our guide to the Paris Agreement, US withdrawal and why the UNFCCC matters.

How TCFD becomes UK SRS

The move from TCFD to UK SRS is not just a change of label. It is a move from a flexible recommendations framework toward a more specified disclosure standard.

TCFD gave companies a structure. UK SRS S2 gives more detailed requirements for climate-related disclosures, based on IFRS S2. It keeps the familiar pillars, but increases the emphasis on connectivity, consistency and investor-useful detail. The FCA's consultation is explicit that existing TCFD-aligned rules have improved disclosure, but that the end of the TCFD and the arrival of ISSB standards mean the UK rulebook needs to evolve.

The proposed shift also changes the tone of compliance. Under current listing rules, companies have made TCFD-aligned disclosures on a comply-or-explain basis. Under the FCA's proposals, UK SRS S2 climate reporting would become mandatory for in-scope listed companies, except for Scope 3 emissions, where comply-or-explain treatment would continue.

That is an important distinction. A company should not assume that a current TCFD report can simply be renamed as a UK SRS report. The existing work is a foundation, but UK SRS asks for more precise, connected and standards-based disclosure.

What UK companies should do now

Companies already producing TCFD-aligned disclosures should not wait passively for the final FCA policy statement.

The first step is to map the existing disclosure against the four pillars and look for weak connections. Does governance show real oversight or just broad responsibility? Does strategy connect climate risk to financial planning? Does risk management show integration with enterprise risk processes? Do metrics connect back to the risks and opportunities described earlier in the report?

The second step is to improve scenario analysis. This is often the weakest part of TCFD reporting. A useful scenario analysis should not simply describe a warming pathway. It should explain what that pathway could mean for the company's markets, costs, assets, operations and capital allocation.

The third step is Scope 3 preparation. Even where Scope 3 remains comply-or-explain, companies should not treat that as permission to ignore it. The FCA's proposal recognises data-quality challenges, but the direction of travel is clear: companies will be expected either to disclose Scope 3 emissions or explain clearly why they have not done so.

The fourth step is to prepare a UK SRS gap analysis. For listed companies, this means comparing existing TCFD reporting with UK SRS S2 requirements and FCA proposals. For companies outside formal scope, it means understanding what investors, lenders and customers are likely to ask for.

Common mistakes in TCFD reporting

The most common mistake is treating TCFD as a sustainability narrative. A company may have credible environmental ambitions and still produce weak TCFD disclosure. The framework is not asking only whether the company is trying to reduce emissions. It is asking whether climate-related risks and opportunities have been identified, governed, assessed, managed and tracked.

Another mistake is describing climate risk without explaining financial impact. A report may say that climate change could affect operations, supply chains or customer demand. That is a start, but it is not enough. Readers need to know which operations, which supply chains, which customers, which time horizons and what financial consequences management has considered.

Weak governance is also common. Board oversight is often claimed in a sentence but not evidenced through committee responsibilities, reporting frequency, executive ownership or decision-making processes. Under closer scrutiny, a governance claim needs to show how the board actually receives, challenges and acts on climate-risk information.

Scenario analysis can also become decorative. A report may include a page on a 1.5C pathway or a higher-warming scenario without showing how those scenarios affect the company's own business. That turns scenario analysis into background reading rather than strategic testing.

Finally, metrics can become disconnected from the rest of the disclosure. Emissions data is useful, but it should not be a lonely table. If energy risk is material, the company should show energy metrics. If physical risk is material, asset exposure matters. If customer transition demand is material, revenue exposure may be relevant. The data should prove the story the company is telling.

What comes after TCFD?

TCFD's importance is not ending. It is being institutionalised.

The four-pillar structure survives in IFRS S2 and UK SRS S2. The focus on financial materiality survives. Scenario analysis survives. Governance, strategy, risk management, metrics and targets remain the skeleton of climate disclosure.

What changes is the level of specificity. UK SRS S2 is more detailed than TCFD. It is more closely connected to financial reporting. It reduces the scope for vague disclosure and asks companies to explain climate-related risks and opportunities in a way that investors can use.

For companies that have treated TCFD seriously, the transition should be manageable. The work already done on governance, scenario analysis, emissions data and risk management becomes the base layer for UK SRS readiness.

For companies that have treated TCFD as a box-ticking exercise, the transition is more challenging. UK SRS S2 is likely to expose weak governance, generic scenario analysis and metrics that are not connected to business strategy.

That is the real lesson of TCFD. It began as a voluntary framework. It became mandatory in parts of the UK market. It has now become the structure beneath the next generation of climate disclosure.

Bottom line

TCFD changed climate disclosure by forcing a simple question into financial reporting: what could climate change do to the business? That question is not going away. UK SRS S2, IFRS S2 and investor expectations all carry it forward.

FAQ

What does TCFD stand for?

TCFD stands for Task Force on Climate-related Financial Disclosures. It was established by the Financial Stability Board in 2015 and published its final recommendations in 2017.

Is TCFD still used in the UK?

Yes. TCFD-aligned requirements still apply in several parts of the UK reporting framework, including listed-company rules, large-company climate-related financial disclosure rules and FCA rules for some financial firms. The task force itself disbanded in 2023.

Is TCFD mandatory?

It depends on the organisation. Some listed companies, large UK companies, limited liability partnerships and FCA-regulated financial firms are subject to mandatory TCFD-aligned or TCFD-consistent disclosure requirements. Smaller companies may not be directly in scope, but may still be asked for TCFD-style information by investors, banks, insurers or large customers.

What are the four TCFD pillars?

The four TCFD pillars are governance, strategy, risk management, and metrics and targets. Together they ask who owns climate risk, how it affects the business, how it is managed and what data is used to track it.

Is TCFD the same as ISSB?

No. The International Sustainability Standards Board developed IFRS S1 (International Financial Reporting Standard S1) and IFRS S2. IFRS S2 incorporates and builds on the TCFD framework. From 2024, responsibility for monitoring progress on climate-related disclosures moved to the foundation that houses the ISSB.

Is TCFD the same as UK SRS?

No. UK Sustainability Reporting Standards S1 and S2 are the UK-endorsed standards based on IFRS Sustainability Disclosure Standards. UK SRS S2 is built on the TCFD architecture, but it is a more detailed reporting standard.

Does TCFD require Scope 3 emissions disclosure?

TCFD expects companies to disclose relevant metrics and targets, including greenhouse gas emissions where material. In practice, Scope 3 requirements depend on the reporting regime. The FCA's CP26/5 proposes that Scope 3 reporting under UK SRS S2 should remain on a comply-or-explain basis for in-scope listed companies, with transitional relief.

Does TCFD require a net zero target?

No. TCFD is a climate-related financial disclosure framework, not a target-setting framework. A company can set a net zero target and still have weak TCFD disclosure. A company can produce strong TCFD disclosure without having made a net zero commitment.
