From TCFD to TNFD: Evolution of Nature Disclosure
Building on established foundations
The TNFD did not emerge in a vacuum. It was designed to complement and build upon the Task Force on Climate-related Financial Disclosures (TCFD), the most influential voluntary disclosure framework of the past decade. Understanding the TCFD's architecture, impact, and limitations is the most direct path to understanding why the TNFD was created and how it was designed.
The TCFD: Origin and Impact
The Task Force on Climate-related Financial Disclosures was established in 2015 by the Financial Stability Board, under the chairmanship of Michael Bloomberg and Mark Carney (then Governor of the Bank of England). Its mandate was to develop voluntary, consistent climate-related financial disclosures that would be useful to investors, lenders, and insurance underwriters.
The TCFD published its final recommendations in June 2017. Structured around four thematic pillars (Governance, Strategy, Risk Management, and Metrics and Targets), the framework was deliberately designed to embed climate risk within mainstream financial reporting rather than in separate sustainability reports. By 2023, TCFD recommendations had been adopted or referenced by:
- More than 100 countries and jurisdictions in their regulatory frameworks or guidance.
- Over 4,000 organisations with combined market capitalisation exceeding $26 trillion as voluntary supporters.
- The ISSB's IFRS S2 standard, which effectively absorbed and institutionalised TCFD's recommendations into mandatory international financial reporting standards.
- Mandatory disclosure regimes in the UK, EU (CSRD), Singapore, New Zealand, and Japan, among others.
Example: How TCFD Changed Disclosure Practice
Before TCFD, climate risk disclosures by corporations were fragmented, inconsistent, and typically buried in sustainability or CSR reports that few investors read. After TCFD, major asset managers like BlackRock began requiring TCFD-aligned disclosures from portfolio companies as a condition of engagement. The 2021 UK Companies Act amendments made TCFD reporting mandatory for around 1,300 large UK companies. This mainstreaming of climate risk disclosure into financial reporting provided the institutional template that the TNFD explicitly adopted for nature.
Why Nature Needed Its Own Framework
If the TCFD was so successful, why couldn't it simply be extended to cover nature? The answer lies in the fundamental differences between climate and nature as risk categories:
| Dimension | Climate (TCFD) | Nature (TNFD) |
|---|---|---|
| Primary metric | GHG emissions (tCO₂e) | Multiple: biodiversity, water, soil, ocean |
| Key unit | Global (atmospheric concentration) | Local/regional (location-specific) |
| Direction of action | Primarily reduction (of emissions) | Reduction of harm AND restoration |
| Data maturity | Relatively mature (30+ years of science) | Rapidly evolving; significant gaps |
| Framework goal | Net zero greenhouse gas emissions | Nature-positive (halt and reverse loss) |
| Stakeholder scope | Primarily financial | Financial plus IPLCs, communities |
The science-based targets for climate are built around a single global goal: limiting warming to 1.5 degrees Celsius above pre-industrial levels. Every tonne of CO₂ reduced anywhere in the world contributes equally to this goal. Nature loss is fundamentally different: a restored wetland in Brazil cannot substitute for a destroyed coral reef in the Philippines. Location specificity is not a technical detail; it is a core feature of nature that demands a fundamentally different disclosure architecture.
Analogy: Climate vs Nature as Risk Domains
Climate risk is like managing the temperature of a single room. One thermostat, one metric, one target. Nature risk is like managing the health of a complex building with hundreds of interconnected systems: plumbing, electrical, structural, HVAC, each with its own indicators, failure modes, and maintenance requirements, and all interacting with one another. You cannot substitute a well-functioning plumbing system for a failed electrical one. Similarly, restored forest in one watershed cannot offset a depleted aquifer in another.
The TNFD Development Timeline
The TNFD was formally established in June 2021, following two years of preparatory work led by the Global Canopy, UNDP, UNEP FI, and WWF. The Taskforce of 40 senior executives from financial institutions, corporates, and market service providers across 18 countries was co-chaired by David Craig (former CEO of Refinitiv) and H.E. Razan Al Mubarak (President of the IUCN and UN Climate Change High-Level Champion for COP28).
- June 2021: TNFD formally launched with 40 Taskforce members representing over $20.6 trillion in assets under management.
- March 2022: Beta v0.1 framework released for market testing and feedback, launching an 18-month iterative development process.
- November 2022: Fourth and final beta framework (v0.4) released; consultation closed in January 2023.
- September 2023: Final TNFD Recommendations v1.0 published at New York Climate Week, coinciding with the UN General Assembly and the Leaders' Pledge for Nature.
- 2024: Over 400 organisations publicly committed to TNFD adoption, representing more than $4 trillion in market capitalisation.
- 2025: First wave of TNFD-aligned annual reports published; TNFD 2025 Status Report tracks adoption progress.
Key Differences from TCFD: What's New
The TNFD shares the TCFD's four-pillar architecture (Governance, Strategy, Risk and Impact Management, Metrics and Targets) but introduces several significant innovations that reflect the unique character of nature-related risks:
- Dependencies and impacts: TNFD explicitly addresses both what nature does for business (dependencies) and what business does to nature (impacts). TCFD focused primarily on risks to the organisation. TNFD adds impacts on nature as a disclosure category in its own right.
- The LEAP Approach: TNFD provides a structured assessment process (Locate, Evaluate, Assess, Prepare) to help organisations identify and prioritise their most material nature-related issues. There is no equivalent methodological guidance in TCFD.
- Location specificity: TNFD requires organisations to disclose the locations of their assets and activities, particularly where they interface with priority ecosystems (Key Biodiversity Areas, Ramsar wetlands, Indigenous lands). This geospatial dimension is absent from TCFD.
- Indigenous Peoples and Local Communities: TNFD includes explicit requirements for organisations to describe their human rights policies and engagement activities with Indigenous Peoples, Local Communities (IPLCs), and affected stakeholders. This reflects the recognition that nature governance is inseparable from social justice.
- The TNFD Conceptual Foundations: TNFD introduces a specific conceptual architecture including a Nature-Related Risks and Opportunities framework, a Biome typology adapted from the IPBES conceptual framework, and an explicit nexus between climate and nature risks.
The Policy Context: Kunming-Montreal GBF
The TNFD Recommendations were explicitly designed to support implementation of the Kunming-Montreal Global Biodiversity Framework (GBF), adopted at CBD COP15 in December 2022 in Montreal. Target 15 of the GBF is the most directly relevant to the private sector: it calls on governments to "take legal, administrative or policy measures to encourage and enable business...to regularly monitor, assess and transparently disclose their risks, dependencies, and impacts on biodiversity."
The TNFD recommendations are explicitly cited in the GBF's monitoring framework as the relevant private sector disclosure standard. This creates a direct policy linkage between international treaty obligations and corporate reporting, one that will increasingly translate into mandatory national disclosure requirements as GBF signatories implement Target 15.
Key Takeaways
- 1TCFD, established in 2015 and publishing final recommendations in 2017, created the institutional template for the TNFD: four pillars (Governance, Strategy, Risk Management, Metrics and Targets) embedded in mainstream financial reporting
- 2Nature required its own framework because nature risk is inherently location-specific, multi-metric, and requires addressing both harm reduction and active restoration, fundamental differences from the single-metric, globally fungible character of climate risk
- 3TNFD was formally established in June 2021, published four beta versions for market testing, and released final v1.0 recommendations in September 2023, with over 400 early adopters
- 4Key TNFD innovations beyond TCFD include: explicit dependency and impact assessment, the LEAP Approach methodology, location-specific disclosure, and mandatory engagement with Indigenous Peoples and Local Communities
- 5TNFD is aligned with Target 15 of the Kunming-Montreal Global Biodiversity Framework, creating a direct link between international treaty obligations and corporate disclosure practice
