TCFD / TNFD ↔ IFRS
How TCFD became embedded in IFRS S2 and how TNFD concepts extend the same logic to nature.
In 2015, Mark Carney, then Governor of the Bank of England, gave a speech at Lloyd's of London. He called climate change "the tragedy of the horizon" — a risk that was visible to everyone but acted on by no one, because its worst effects lay beyond the planning horizon of every institution. He announced the creation of the Task Force on Climate-related Financial Disclosures. The TCFD would create a framework for companies to disclose their climate risks. Four pillars: governance, strategy, risk management, metrics and targets.
Eight years later, the TCFD was absorbed into IFRS S2. The Financial Stability Board transferred monitoring responsibilities to the ISSB in 2024. The four pillars became the structure of the standard. Governance (§5–7), strategy (§8–24), risk management (§25–26), metrics and targets (§27–36). Carney's "tragedy of the horizon" became a disclosure requirement.
The TNFD — the Taskforce on Nature-related Financial Disclosures — extends the same logic to nature. It uses the same four pillars: governance, strategy, risk management, metrics and targets. But instead of climate, it focuses on biodiversity, ecosystems, and ecosystem services. The ISSB has an active project on nature-related disclosures. When it is published, it will likely follow the same pattern: a task force's framework becomes a standard's structure. The tragedy of the horizon — once a speech — is now a standard.
TCFD became IFRS S2; TNFD may become the nature standard. The four-pillar structure — governance, strategy, risk, metrics — is the template.
In Plain Language
TCFD became IFRS S2. Its four-pillar structure — governance, strategy, risk management, metrics and targets — is now the architecture of the climate standard. TNFD extends the same logic to nature, with the ISSB researching a biodiversity disclosure standard.
- TCFD became IFRS S2; TNFD may become the nature standard. The four-pillar structure — governance, strategy, risk, metrics — is the template.
- The TCFD's four pillars are now the structure of IFRS S2: governance (§5–7), strategy (§8–24), risk management (§25–26), metrics and targets (§27–36).
- The practical test is whether a company can map its TCFD disclosure directly to the IFRS S2 paragraphs that absorbed it — with no gap between the old framework and the new standard.
