What TNFD is and why it was created
The Taskforce on Nature-related Financial Disclosures (TNFD) was established in 2021 by 34 financial institutions and corporations, with backing from G7 governments, UNDP, UNEP FI, and WWF. Its mandate was explicit: do for biodiversity and nature what TCFD did for climate — create a voluntary, market-based disclosure framework that eventually becomes mandatory.
The Kunming-Montreal Global Biodiversity Framework (2022) agreed by 196 countries includes Target 15, which explicitly calls for large companies and financial institutions to regularly disclose nature-related risks, dependencies, and impacts. TNFD is the voluntary implementation pathway for Target 15. By 2030, nature disclosure is expected to be mandatory for large companies in most major jurisdictions.
The scale of nature risk
The World Economic Forum estimates that $44 trillion of economic value — more than half of global GDP — is moderately or highly dependent on nature and ecosystem services. Yet until TNFD, companies had no standardised way to assess or disclose this dependency. Climate risk quantification is mature by comparison.
TNFD structure: familiar but more complex than TCFD
TNFD follows TCFD's four-pillar structure: Governance, Strategy, Risk Management, and Metrics & Targets. This was deliberate — building on TCFD's institutional credibility and established corporate disclosure processes. But the underlying science is considerably more complex.
| Pillar | TCFD equivalent | What TNFD adds |
|---|---|---|
| Governance | Board oversight of climate risks | Board oversight of nature risks and dependencies |
| Strategy | Climate scenario analysis | Location-specific nature assessment (LEAP approach) |
| Risk & Impact Management | Climate risk identification | Four capitals: natural, social, human, financial |
| Metrics & Targets | GHG emissions, climate scenarios | 14 core metrics across impacts, dependencies, and state of nature |
The LEAP approach: location is everything
The most distinctive element of TNFD relative to TCFD is its location-specificity. Climate change is essentially a global average problem — a tonne of CO₂ emitted anywhere has the same warming effect. Nature is completely different: the biodiversity value of a hectare of land in an Amazon hotspot is vastly different from a hectare in an already-degraded industrial zone. TNFD's LEAP methodology requires companies to assess nature risks and impacts at the specific location where they operate and source.
- L — Locate: Map your interface with nature by identifying sites of operation and priority supply chain locations on biodiversity maps
- E — Evaluate: Assess dependencies and impacts on nature at those specific locations
- A — Assess: Identify material nature-related risks and opportunities given your dependencies and impacts
- P — Prepare: Develop strategy, targets, and disclosure in response to findings
The 14 core metrics
TNFD's September 2023 final framework includes 14 core global metrics and additional sector-specific metrics. The core metrics cover:
- Land use: hectares of natural habitat in operational and sourcing footprint
- Freshwater use and pollution discharges: volumes and quality
- Greenhouse gas emissions: linked to TCFD
- Air pollutants: SOx, NOx, PM2.5 with nature-impact weighting
- Waste and pollution: volume and hazardous classification
- Biodiversity-sensitive area exposure: % of operations/sourcing in or near IUCN Key Biodiversity Areas
- Nature-related financial risks: assets exposed to physical, regulatory, and market nature risks
Which sectors face highest nature-related risk?
Unlike climate, where the energy sector dominates, nature risk is spread much more broadly. The TNFD identifies eight sectors as priority high-nature-dependency sectors:
| Sector | Primary dependency | Primary impact |
|---|---|---|
| Agriculture & food | Pollination, soil health, freshwater | Land use change, fertiliser runoff |
| Forestry & paper | Forest ecosystems, water regulation | Deforestation, biodiversity loss |
| Mining | Subsoil resources, land stability | Habitat destruction, water pollution |
| Oil & gas | Land, water, air quality | Pollution, habitat fragmentation |
| Chemicals | Freshwater, waste assimilation | Pollution, toxic discharge |
| Construction | Land, aggregates, water | Habitat loss, impervious surfaces |
| Pharmaceuticals | Genetic resources, traditional knowledge | Biopiracy risk, over-harvesting |
| Financial services | All sectors via lending/investing | Financing nature-harming activities |
Early adopter status
Over 320 organisations representing $6.5T in AUM had committed to TNFD-aligned disclosure by end 2024 — including HSBC, BNP Paribas, AXA, and Unilever. By 2026 adoption has accelerated significantly. Companies making voluntary disclosures now will have a significant advantage when mandatory requirements arrive, estimated for most EU companies by 2028 under CSRD Article 19.
What this means for ESG analysts in 2026
TNFD disclosures are still voluntary and patchy in 2026. But three things are shifting. First, institutional investors — particularly European asset managers — are beginning to ask about nature risk in their engagement programmes. Second, the Biodiversity COP30 process is likely to strengthen Target 15 compliance mechanisms. Third, courts in the Netherlands, UK, and France have begun accepting biodiversity damage as actionable corporate negligence.
The practical implication: agriculture, food, mining, and construction companies with material operations in biodiversity-sensitive areas face emerging regulatory and litigation risk that current ESG scores systematically underweight. Analysing TNFD-aligned disclosures — or the absence of them — is becoming a source of alpha.
