Overview
The Task Force on Climate-related Financial Disclosures (TCFD) was established in 2015 by the Financial Stability Board (FSB), at the instigation of Mark Carney, then FSB Chair and Governor of the Bank of England. Its mandate was to develop voluntary, consistent recommendations for how companies should disclose climate-related risks and opportunities to investors and lenders. The final recommendations were published in June 2017.
TCFD’s core insight was that climate change is a financial risk, not just an environmental one, and that markets cannot price that risk if companies do not disclose it. This was not a radical idea in environmental circles, but it was genuinely new language for mainstream financial regulators and the companies they oversaw. TCFD gave Climate Finance practitioners a shared vocabulary and a structured way to engage with boards and CFOs.
Adoption grew faster than almost anyone predicted. By 2023, more than 4,000 organisations in over 100 countries had expressed support. Major regulators, including the UK’s FCA, New Zealand, Switzerland, and Hong Kong, moved to make TCFD-aligned disclosure mandatory. The framework became the de facto global standard.
In 2024, TCFD formally dissolved. Its work was absorbed by the ISSB (International Sustainability Standards Board), which had already built its climate standard (IFRS S2) directly on TCFD’s foundations. TCFD’s legacy is that it no longer needs to exist separately, it became the baseline.
The Four Pillars
TCFD organised climate disclosure around four interconnected themes. These pillars remain the backbone of virtually every climate disclosure framework operating today.
Governance asks how the board and management oversee climate-related risks and opportunities. The intent is to establish accountability at the top of the organisation, not delegate climate to the sustainability team and leave it there.
Strategy asks how climate risks and opportunities affect the organisation’s business model, strategy, and financial planning. Crucially, TCFD introduced the concept of scenario analysis here, companies should test their strategy against different possible futures, including a scenario consistent with limiting warming to 1.5°C or 2°C.
Risk Management asks how the company identifies, assesses, and manages climate-related risks, and how that process integrates with overall enterprise risk management. This is where Physical Risks and Transition Risks get sorted and prioritised.
Metrics and Targets asks what the company measures and what goals it has set. This pillar connects to GHG emissions accounting, specifically Scope 1, 2, and (where relevant) Scope 3. See GHG Scopes for definitions.
Physical and Transition Risk
TCFD gave mainstream finance its standard taxonomy of climate risk. Physical risks are the direct impacts of a changing climate, storms, floods, heat, drought, split between acute (event-driven) and chronic (gradual shifts). Transition risks are the financial consequences of moving to a low-carbon economy, policy changes, technology shifts, market repricing, reputational damage. See Physical Risks and Transition Risks for full treatments.
This two-category framework is now used by central banks, regulators, rating agencies, and every major disclosure standard. It is one of TCFD’s most durable contributions.
Scenario Analysis
TCFD’s recommendation that companies conduct climate scenario analysis was genuinely novel for corporate disclosure. It asked organisations to think about futures rather than just report on the past. The most commonly used scenarios come from the IPCC and the International Energy Agency (IEA), including a “Net Zero by 2050” pathway and a range of higher-warming alternatives.
Scenario analysis is technically demanding and hard to standardise, a persistent criticism of TCFD in practice. The quality of scenario analysis in company reports varies enormously, which is one reason the ISSB added more specific guidance in its successor standards.
