TCFD vs TNFD: Key Differences Explained

Quick Comparison

• Focus area: TCFD addresses climate-related financial risks and opportunities. TNFD addresses nature-related risks and opportunities, covering biodiversity, ecosystems, and natural capital.
• Structure: Both use the same four-pillar framework — Governance, Strategy, Risk Management, and Metrics & Targets. TNFD deliberately mirrors TCFD to reduce the learning curve for companies already reporting on climate.
• Publisher: TCFD was created by the Financial Stability Board in 2015 and published recommendations in 2017. TNFD was launched in 2021 by a coalition including UNDP, UNEP FI, WWF, and Global Canopy, publishing final recommendations in September 2023.
• Current status: TCFD completed its mandate in 2023 and its monitoring responsibilities transferred to the ISSB. TNFD adoption is still growing, but since the ISSB decided in November 2025 to build nature-related requirements on its recommendations, the TNFD has been completing its work in progress and pausing new technical work while it supports the ISSB.
• Data maturity: Climate data (emissions, energy, carbon pricing) is relatively standardized with established measurement protocols. Nature data (biodiversity metrics, ecosystem dependencies, land use impact) is less standardized with emerging measurement tools.

What is TCFD?

The Task Force on Climate-related Financial Disclosures was established by the Financial Stability Board in 2015 and published its recommendations in 2017. TCFD created the framework for climate risk disclosure that has become the global standard structure — organized around four pillars: governance, strategy, risk management, and metrics/targets.

TCFD's core contribution was framing climate change as a financial risk rather than purely an environmental concern. By asking companies to disclose how climate risks and opportunities affect their financial position, TCFD made climate relevant to CFOs, boards, and investors — not just sustainability teams.

Key TCFD requirements include disclosure of board and management oversight of climate risks, the actual and potential impacts of climate risks on business strategy, how the organization identifies and manages climate risks, and the metrics used to assess climate-related performance. Scenario analysis — stress-testing business models under different warming pathways — became TCFD's signature requirement.

TCFD achieved remarkable adoption. About 4,900 organizations in 103 jurisdictions supported the framework, according to the TCFD. Multiple jurisdictions made TCFD-aligned disclosure mandatory or referenced it in regulation — the UK, Japan, New Zealand, Singapore, Hong Kong, and others. When the ISSB published IFRS S2, it built directly on TCFD's structure, effectively codifying TCFD recommendations into a formal global standard.

The TCFD disbanded in October 2023, having achieved its mission. The FSB transferred monitoring responsibilities to the ISSB. But the TCFD framework — its four pillars, its scenario analysis approach, its risk categorization (physical and transition) — remains the foundation of climate disclosure globally.

What is TNFD?

The Taskforce on Nature-related Financial Disclosures published its final recommendations in September 2023, applying TCFD's proven disclosure architecture to nature and biodiversity. Where TCFD asked "how does climate affect your business and how does your business affect climate?", TNFD asks the same questions about nature.

TNFD defines nature through four realms: land, ocean, freshwater, and atmosphere. It considers both the dependencies businesses have on nature (clean water, pollination, soil fertility, climate regulation) and the impacts businesses have on nature (habitat destruction, pollution, resource extraction, invasive species introduction).

The TNFD framework introduces the LEAP approach — Locate, Evaluate, Assess, Prepare — as a practical methodology for identifying and assessing nature-related risks. Companies start by locating their interface with nature (where do operations and supply chains interact with ecosystems?), evaluate dependencies and impacts, assess material risks and opportunities, and prepare disclosures.

This location-specific approach is a key distinction from TCFD. Climate risk can be assessed at a corporate level using aggregate emissions data. Nature risk requires understanding specific ecosystems — a palm oil supplier's impact depends on whether the plantation is in intact rainforest or degraded agricultural land. A manufacturer's water dependency varies dramatically by watershed.

TNFD adoption is growing rapidly. According to the TNFD's 2026 status report, 802 organizations had committed to TNFD-aligned reporting, up from 502 in 2024, and Japanese organizations make up the largest share (24%) of companies found publishing TNFD-aligned reports. Under the EU's CSRD, companies in scope must report on biodiversity and ecosystems under ESRS E4 when the topic is material to them. CBD's Global Biodiversity Framework (adopted at COP15) set targets that align with TNFD's disclosure architecture. In November 2025 the ISSB decided to develop nature-related disclosure requirements that draw on the TNFD's recommendations, with an exposure draft targeted for October 2026; the TNFD is completing its work in progress and pausing new technical work while it supports the ISSB.

Key Differences

• Subject matter: TCFD covers climate change — greenhouse gas emissions, physical climate hazards, energy transition, carbon pricing. TNFD covers the broader natural world — biodiversity loss, ecosystem degradation, land use change, water stress, ocean health, deforestation, pollution.
• Measurement maturity: Carbon emissions have a standardized measurement protocol (GHG Protocol), established units (tonnes CO₂e), and decades of reporting experience. Nature metrics are less standardized — there's no single "biodiversity equivalent" of tonnes of CO₂. TNFD recommends multiple metrics including species abundance, ecosystem extent, and ecosystem condition.
• Location dependency: TCFD metrics can be aggregated at corporate level — total Scope 1 emissions are the same regardless of where they're emitted. TNFD metrics are inherently location-specific — the impact of water withdrawal depends entirely on the watershed. This makes TNFD data collection more complex and supply chain traceability more critical.
• Interconnection with climate: Climate change is one of five drivers of nature loss (alongside land/sea use change, resource exploitation, pollution, and invasive species). TNFD explicitly recognizes this connection. Nature-based solutions (forests, wetlands, mangroves) also serve as climate mitigation and adaptation. The two frameworks are complementary, not parallel.
• Sector relevance: TCFD applies broadly — virtually every company has climate risk exposure. TNFD's urgency varies more by sector. Agriculture, food/beverage, forestry, mining, pharmaceuticals, construction, and financial services (through portfolio exposure) face the most immediate nature-related risks.
• Regulatory momentum: TCFD has been mandated or referenced by regulators in major economies since 2020. TNFD regulatory adoption is earlier-stage — CSRD covers biodiversity where material, COP15 targets create policy pressure, and the ISSB is developing nature-related requirements that draw on the TNFD, but standalone TNFD mandates are still emerging.

When to Use Each

Focus on TCFD/ISSB S2 when:

• You need to meet mandatory climate disclosure requirements in your jurisdiction
• Your primary risks are climate-related (carbon-intensive operations, fossil fuel exposure, physical climate hazards)
• You're building your first structured sustainability disclosure program
• Investors are requesting climate-specific risk data and scenario analysis

Adopt TNFD when:

• Your business directly depends on natural resources (agriculture, forestry, fisheries, water-intensive manufacturing)
• You operate in or source from biodiversity-sensitive regions
• You're subject to CSRD and need to address ESRS E4 (biodiversity and ecosystems)
• Your sector is identified by TNFD as high nature-dependency or high nature-impact
• You want to stay ahead of emerging nature-related regulation and investor expectations

Report under both when:

• You want a complete picture of environmental risk and impact
• CSRD applies (requiring climate and nature disclosure where material)
• Your business model depends on both stable climate conditions AND healthy ecosystems
• You're a financial institution assessing portfolio-level environmental risk across both dimensions

Council Fire's Recommendation

If you've already built TCFD-aligned disclosure, you have the structural foundation for TNFD — the four pillars are identical. The work is in extending your risk assessment from climate to nature, building location-specific data on ecosystem dependencies and impacts, and developing nature-related metrics alongside your climate metrics.

Don't wait for TNFD mandates to start. Nature-related risks are already materializing — water scarcity affecting semiconductor manufacturing, pollinator decline threatening agricultural supply chains, deforestation rules set to restrict EU market access from December 2026. Companies that map their nature dependencies now will manage these risks better than those scrambling to comply later.

Council Fire helps companies extend their climate disclosure programs to cover nature-related risks, building the LEAP assessment methodology, location-specific data infrastructure, and integrated reporting that satisfies both TCFD/ISSB and TNFD requirements.
