TNFD Recommendations: From Voluntary Disclosure to Board-Level Action
Key Takeaways
- TNFD’s 14 recommendations across four pillars are rapidly becoming a de facto expectation for institutional investors, CSRD reporters, and UK SDR-aligned funds
- The LEAP approach (Locate, Evaluate, Assess, Prepare) provides a structured, repeatable methodology for identifying nature-related dependencies and impacts
- UK companies in priority sectors — agriculture, construction, real estate, utilities, financial services — face the most immediate pressure to disclose
- A nature-risk register, built alongside your existing climate-risk register, is the most practical first step toward TNFD alignment
- TNFD disclosure connects directly to Biodiversity Net Gain (BNG) obligations already embedded in UK planning law
Why Nature Has Become a Board-Level Risk
The World Economic Forum’s Global Risks Report has consistently ranked biodiversity loss and ecosystem collapse among the top five risks by severity over the past four years. Yet until the Taskforce on Nature-related Financial Disclosures (TNFD) published its final recommendations in September 2023, there was no globally accepted framework for translating nature risk into corporate disclosure.
That gap is closing rapidly. Over 320 organisations have registered as TNFD Adopters, and the framework is now explicitly referenced in the EU’s Corporate Sustainability Reporting Directive (CSRD) through ESRS E4 (Biodiversity and Ecosystems). The UK’s Sustainability Disclosure Requirements (SDR), while currently focused on investment products, are expected to expand toward entity-level nature disclosure. For UK boards, the question is no longer whether to engage with TNFD, but how quickly you can build the internal capability to do so credibly.
The 14 Recommendations: Structure and Scope
TNFD’s recommendations mirror the four-pillar structure established by TCFD, making them immediately familiar to organisations already reporting on climate:
Governance (3 recommendations): Board oversight of nature-related dependencies, impacts, risks and opportunities. Management’s role in assessing and managing these issues. Integration of nature considerations into organisational purpose, strategy and policies.
Strategy (4 recommendations): Identification of nature-related dependencies, impacts, risks and opportunities. The effect on business model, value chain, strategy and financial planning. Resilience of strategy under different scenarios. Location-specific considerations for priority areas.
Risk & Impact Management (3 recommendations): Processes for identifying and assessing nature-related dependencies, impacts, risks and opportunities. How these are managed and mitigated. Integration with overall enterprise risk management.
Metrics & Targets (4 recommendations): Metrics used to assess and manage material nature-related issues. Dependencies and impacts on nature. Targets and performance against them. The approach to setting and reviewing targets.
The critical addition relative to TCFD is the explicit inclusion of dependencies and impacts alongside risks and opportunities. This reflects the reality that nature risk is fundamentally bidirectional: your business depends on natural capital (pollination, water purification, soil stability), and your operations impact natural systems (habitat conversion, pollution, resource extraction). Both directions create financial exposure.
The LEAP Approach: A Practical Walkthrough
TNFD developed the LEAP approach as an integrated assessment process. It is not mandatory for disclosure, but it provides the most structured pathway from ignorance to action.
L — Locate Your Interface with Nature
Map where your direct operations, upstream supply chain, and downstream value chain interact with natural systems. This is inherently spatial. Use tools such as the Integrated Biodiversity Assessment Tool (IBAT), the ENCORE database (Exploring Natural Capital Opportunities, Risks and Exposure), and national-level datasets such as Natural England’s Priority Habitat Inventory. For UK operations, cross-reference your site locations against Sites of Special Scientific Interest (SSSIs), Special Areas of Conservation (SACs), and the National Habitat Network.
Identify biomes and ecosystems at each interface point. A manufacturing facility adjacent to a chalk stream faces different nature dependencies than one in an urban brownfield site. Granularity matters.
E — Evaluate Dependencies and Impacts
For each located interface, assess which ecosystem services your operations depend upon (water regulation, flood attenuation, raw material provision, genetic resources) and what impacts your operations have (land-use change, water abstraction, pollution discharge, invasive species introduction). The ENCORE tool is particularly useful here, mapping sectoral dependencies on ecosystem services at the sub-industry level.
Quantify where possible, but do not let the absence of perfect data prevent qualitative assessment. A construction company that cannot precisely quantify its dependence on soil stability can still recognise that building on floodplain without adequate assessment creates material risk.
A — Assess Material Risks and Opportunities
Translate dependencies and impacts into financial risk categories: physical risk (ecosystem degradation reducing service provision), transition risk (regulatory tightening, market preference shifts), systemic risk (tipping points in interconnected natural systems). Map these to your existing enterprise risk management framework using consistent likelihood and severity scales.
This is also where opportunities emerge. Companies that proactively restore natural capital, develop nature-positive products, or build supply chain resilience against ecosystem degradation can capture competitive advantage.
P — Prepare to Respond and Report
Develop response strategies (avoid, reduce, restore, regenerate, transform), set targets, identify metrics, and prepare disclosure. This phase connects directly to the 14 recommendations and determines the structure of your TNFD report.
Priority Sectors for UK Companies
TNFD has identified priority sectors based on the magnitude of nature dependencies and impacts. For UK companies, the most immediately relevant include:
Agriculture and food production: Direct dependence on soil health, pollination, water quality. UK agriculture alone relies on ecosystem services valued at an estimated £1.5 billion annually for pollination.
Construction and real estate: Land-use change is the single largest driver of biodiversity loss globally. In the UK, the mandatory Biodiversity Net Gain (BNG) requirement under the Environment Act 2021 makes this sector’s nature interface legally binding, not merely voluntary.
Mining and extractives: Water-intensive operations with significant habitat disturbance. Quarrying, aggregate extraction, and mineral processing all trigger TNFD-relevant dependencies.
Utilities: Water companies face acute nature dependencies (watershed health, aquifer recharge) and significant regulatory pressure from Ofwat and the Environment Agency. Energy utilities interact with nature through land use for generation assets and transmission infrastructure.
Financial services: Banks, insurers, and asset managers face portfolio-level nature risk. The Network for Greening the Financial System (NGFS) has identified nature-related risks as a potential source of systemic financial risk.
Connection to Biodiversity Net Gain
The UK is ahead of many jurisdictions in one critical respect: Biodiversity Net Gain (BNG) became mandatory for most planning applications in England from February 2024 (major developments) and April 2024 (minor developments). Developers must deliver a minimum 10% net gain in biodiversity value, calculated using the statutory biodiversity metric, and maintained for at least 30 years.
This creates a direct operational connection to TNFD. Companies subject to BNG are already generating nature-related data — habitat condition assessments, biodiversity unit calculations, management and monitoring plans — that can feed directly into TNFD disclosure. The challenge is integrating BNG compliance data, which tends to sit in planning and development teams, into corporate sustainability reporting processes owned by finance or ESG functions.
Water Stewardship and Watershed Considerations
Water sits at the intersection of climate and nature risk. UK companies abstracting water, discharging effluent, or operating in water-stressed catchments face nature dependencies that are intensifying under climate change. The Environment Agency’s water resources planning framework already requires major abstractors to consider environmental flow requirements and ecological status under the Water Framework Directive (retained in UK law post-Brexit).
TNFD-aligned water stewardship goes beyond compliance. It requires understanding your watershed context: who else abstracts from the same catchment, what is the ecological condition of receiving waters, what nature-based solutions could reduce your water risk while delivering biodiversity co-benefits. The Alliance for Water Stewardship (AWS) Standard provides a complementary framework that maps well to TNFD’s location-specific requirements.
Building a Nature-Risk Register
The most practical first step toward TNFD alignment is constructing a nature-risk register alongside your existing climate-risk register. The structure should include:
Risk identification: Nature-related risk or opportunity, linked to specific dependency or impact, at a specific location or value chain stage.
Categorisation: Physical, transition, or systemic. Short-term (0–2 years), medium-term (2–5 years), or long-term (5–15 years).
Likelihood and severity: Using your existing ERM scales for consistency and board-level integration.
Current controls: What mitigation or management is already in place (e.g., BNG delivery, environmental management system, supplier codes of conduct).
Residual risk rating: After controls, what exposure remains.
Response strategy: Avoid, reduce, restore, regenerate, or transform. With assigned ownership, timeline, and budget.
This register becomes the foundation for TNFD’s Risk & Impact Management disclosures and feeds directly into Governance reporting (demonstrating board-level oversight of identified nature risks).
TNFD-Aligned Metrics: What to Measure
TNFD recommends a tiered approach to metrics. Core global metrics apply to all sectors and include: land-use change (hectares of natural habitat converted), water use in stressed catchments (megalitres), and pollution indicators (tonnes of key pollutants discharged). Sector-specific metrics add granularity: soil organic carbon for agriculture, marine habitat disturbance for fisheries, deforestation-linked commodity volumes for food and retail.
Data sources available to UK companies include: the JNCC’s UK Biodiversity Indicators, Natural England’s condition assessments for designated sites, the Environment Agency’s Water Quality Archive, Defra’s agri-environment scheme monitoring data, and commercial platforms such as NatureMetrics (eDNA sampling) and Satellite Vu (thermal monitoring).
Start with what you have. Many UK companies already collect environmental data through their Environmental Management Systems (ISO 14001), planning condition compliance, environmental permit returns, and supply chain audits. The gap is usually not data absence but data integration — connecting operational environmental data to corporate disclosure processes.
RSustain Group Experience
The RSustain group brings direct experience in watershed assessment and lake restoration auditing to this advisory area. Our team has conducted comprehensive ecological and environmental audits of watershed systems, evaluating water quality, riparian habitat condition, species inventories, and restoration feasibility. This hands-on experience with natural capital assessment — measuring ecosystem condition, identifying degradation drivers, and designing restoration interventions — directly informs our approach to TNFD advisory for UK clients.
We understand the difference between nature disclosure as a reporting exercise and nature disclosure grounded in genuine ecological understanding. That distinction matters when boards need to make investment decisions about nature-based solutions, habitat restoration, or supply chain transformation.
Implementation Roadmap
Months 1–2: Conduct LEAP scoping. Map operational and value chain interfaces with nature. Identify priority locations using IBAT and ENCORE. Assemble a cross-functional working group (sustainability, risk, operations, procurement, legal).
Months 3–4: Evaluate dependencies and impacts at priority locations. Build the nature-risk register. Identify data gaps and commission baseline assessments where needed.
Months 5–6: Assess material risks and opportunities. Integrate nature risks into the enterprise risk management framework. Select core and sector-specific metrics.
Months 7–9: Develop response strategies, set targets, and prepare first TNFD-aligned disclosure. Brief the board. Publish.
For companies already reporting under TCFD, the infrastructure is largely in place. The incremental effort is in the ecological and spatial analysis — understanding where your operations interface with nature and what that means financially.
