Nature and biodiversity risk is reshaping how financial institutions evaluate their portfolios. When Banco Davivienda issued a $50 million biodiversity bond in 2024, its investment committee required proof that the bank had mapped every agricultural loan in its portfolio against ecosystem dependency data. Without that map, the bond could not be priced.

The bank turned to the TNFD nature and biodiversity risk methodology — specifically the LEAP approach — and discovered that 38% of its agri-finance exposure sat within 100 kilometres of a priority watershed.

The pricing exercise took six weeks. The regulatory reporting that followed took two days, because the LEAP workflow had already built the evidence base.

This is the practitioner reality of the TNFD framework biodiversity risk era: nature and biodiversity risk is no longer a sustainability team problem. It sits inside credit models, supply chain resilience and business continuity assessments, and board-level strategy reviews.

The Taskforce on Nature-related Financial Disclosures (TNFD) published its final recommendations in September 2023, and since then adoption has compounded faster than any comparable voluntary framework.

This guide gives risk professionals the step-by-step implementation pathway competitors’ articles skip: full LEAP methodology with worked examples, sector-specific exposure thresholds, SBTN integration, ENCORE tool application, and the regulatory convergence timeline that makes voluntary adoption increasingly non-optional.

The article is structured as a practitioner workflow. You will find the complete guide to the risk assessment process mapped to TNFD’s four pillars, followed by the LEAP phases, sector exposure data, governance design, metrics selection, and the regulatory calendar through 2027.

By the end, you will have everything required to run your first TNFD-aligned nature risk assessment and build a disclosure-ready risk register.

Understanding Nature and Biodiversity Risk: TNFD Framework Architecture

The nature and biodiversity risk framework structure mirrors TCFD’s four-pillar design deliberately — Governance, Strategy, Risk and Impact Management, and Metrics and Targets — so organisations that have completed climate disclosure have a transferable architecture.

The parallel is intentional: TNFD and TCFD are designed to be used together, not sequentially. However, nature risk differs from climate risk in three fundamental ways that practitioners must internalise before applying the framework.

First, nature risk is spatially explicit. A coal plant’s carbon emissions are globally fungible; a mining operation’s impact on a freshwater aquifer depends entirely on which aquifer, in which jurisdiction, under which rainfall regime.

The TNFD recommendations on nature-related risk and opportunity embed this spatial logic throughout — every LEAP phase requires geographic coordinates. Second, nature risk is bidirectional: organisations both depend on and impact ecosystems.

Dependency on pollination creates transition risk if pollinator populations collapse; impact on deforestation creates regulatory and reputational risk independent of operational dependency.

Third, nature metrics are younger and less standardised than carbon metrics, which means data quality varies significantly and scenario analysis is methodologically harder.

The enterprise risk management framework principles of inherent risk, residual risk, and risk appetite translate directly to TNFD. Inherent nature risk is the exposure before management responses; residual nature risk accounts for restoration commitments, supply chain substitutions, and operational controls.

TNFD asks organisations to disclose both, alongside the management actions that reduce the gap — the same structure used in standard RCSA complete guide frameworks.

TNFD PillarCore RequirementPractitioner Action
GovernanceBoard oversight of nature-related risks; management roles assigned; integration with risk committeesAssign nature risk to existing Risk Committee; update risk appetite statement to include nature materiality thresholds

How TNFD Relates to TCFD, ISSB, and CSRD

The TNFD biodiversity disclosure convergence with ISSB is the most significant regulatory development of 2025. The ISSB signed a Memorandum of Understanding with TNFD in 2025 and is targeting an Exposure Draft of incremental nature-related disclosure requirements by COP17 in October 2026.

When that standard is finalised — likely 2027–2028 — TNFD-aligned disclosures will become the baseline for IFRS-reporting entities globally.

In the EU, CSRD’s ESRS E4 (Biodiversity and Ecosystems) already mandates nature reporting for large companies from FY2025, with the LEAP framework explicitly named as a compliant methodology for double materiality assessment.

Organisations that begin TNFD nature and biodiversity risk assessments now will meet both ISSB and CSRD requirements simultaneously.

The TNFD LEAP Methodology: A Step-by-Step Practitioner Walkthrough

LEAP — Locate, Evaluate, Assess, Prepare — is TNFD’s core implementation methodology. It is described in the TNFD LEAP approach guidance document and is designed to be iterative: organisations run LEAP annually, expanding scope and data quality each cycle.

The workflow starts with location data and ends with a disclosure-ready assessment. What follows is each phase with the specific outputs a risk team must produce.

Phase L: Locate — Mapping Business-Nature Interfaces

Locate requires two outputs: a footprint map and a hotspot flag. The footprint map plots all operational sites, supply chain tier-one nodes, and investment portfolio assets against geographic coordinates.

The hotspot flag runs those coordinates against the ENCORE tool to identify which sub-industries have high or very high dependencies and impacts on nature.

ENCORE (Exploring Natural Capital Opportunities, Risks and Exposure) is a free tool developed by UNEP FI, UNEP-WCMC, and Global Canopy that maps 157 NACE sub-industries against 21 ecosystem services (pollination, water regulation, soil formation, etc.) and 11 environmental assets (forests, freshwater, soils).

An agricultural company runs its sub-industry codes through ENCORE and receives a dependency-impact matrix scored High/Medium/Low. Any High or Very High rating triggers mandatory further assessment in Phase E.

L1 screening for a food manufacturing company with operations in three countries might identify: (a) palm oil supply chain — Very High dependency on forest carbon stocks; (b) dairy operations — High dependency on freshwater aquifers; (c) packaging — Medium impact on terrestrial ecosystems.

The output is a prioritised list of locations and value chain nodes for risk identification tools and techniques in Phase E.

Phase E: Evaluate — Identifying Dependencies and Impacts

Evaluate deepens the L1 hotspot flags into cause-and-effect chains. For each flagged interface, the team maps (a) which ecosystem services the business depends on, (b) which environmental assets are affected by operational impacts, and (c) how changes in ecosystem condition translate into financial flows.

The IPBES (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services) ecosystem typology is the TNFD’s recommended reference for classifying biomes and ecosystem conditions.

A practical E-phase output for a mining company might read: ‘Tailings storage at Site X discharges into the Río Turbio watershed (Very High Biodiversity Integrity Index score). Downstream communities use watershed for potable water (high dependency).

Regulatory risk: Chilean environmental court precedents impose restoration bonds of $3–8 million per incident. Reputational risk: three NGO litigation threats filed against comparable operations in 2024.’

This combines ecosystem data, financial exposure, and legal precedent — the triple-lens the complete guide to the risk assessment process requires for any material risk.

Phase A: Assess — Risk and Opportunity Quantification

Assess translates evaluated dependencies and impacts into financial risk ratings using likelihood × consequence scoring consistent with what is ISO 31000 principles.

TNFD distinguishes physical nature risk (ecosystem degradation disrupting operations) from transition nature risk (policy, market, reputational responses to biodiversity loss).

Physical nature risk examples: crop failures from pollinator collapse (food sector), water stress reducing hydroelectric output (energy), coral bleaching reducing fishery catch rates (aquaculture).

Transition nature risk examples: EU deforestation regulation blocking market access for commodity supply chains, mandatory biodiversity offsets increasing project capex, investor divestment from companies with poor biodiversity scores.

For each risk, the assessment team assigns: inherent likelihood (probability × exposure), inherent financial impact (revenue-at-risk, capex uplift, regulatory fine range), existing controls (offset programs, supplier codes, environmental management systems), and residual risk.

The output feeds the risk register template and guide with nature risks integrated alongside operational, financial, and strategic risks — not in a standalone ESG silo.

Phase P: Prepare — Disclosure and Strategy Integration

Prepare converts the risk assessment into TNFD-aligned disclosure content across the four pillars. The disclosure answers 14 recommended disclosure items (governance, strategy, risk management, metrics) drawn directly from the final TNFD recommendations.

Critically, Prepare also asks what the organisation will do differently — which management actions reduce residual risk to within nature risk appetite, and which opportunities (nature-positive products, green finance instruments, supply chain resilience investments) the organisation intends to pursue.

Santander Peru completed a published LEAP pilot for its agri-lending portfolio, identifying palm oil, soy, and cattle ranching exposure in the Amazon basin as the highest priority, and implementing geospatial monitoring of supplier deforestation as the primary control.

The bank’s TNFD LEAP Santander Peru case study is now a reference implementation for financial institutions beginning their nature and biodiversity risk journey.

Sector-Specific Nature and Biodiversity Risk Application

TNFD recognises that nature-related risks manifest differently by sector, and publishes sector-specific additional guidance for the highest-impact industries.

The TNFD sector-specific guidance covers food and agriculture, mining and metals, oil and gas, infrastructure, financial services, and aquaculture.

Each sector guide provides tailored LEAP worksheets, recommended metrics, and illustrative case studies. What follows are the four sectors with the highest materialiy scores across the LEAP framework.

SectorPrimary Nature RiskKey Ecosystem Services at RiskTNFD Priority Metrics
Food & AgriculturePhysical: pollinator collapse; water stress; soil degradationPollination, water regulation, soil formation, genetic resourcesLand use (ha), freshwater consumption (m³), pesticide intensity, supplier deforestation rate
Mining & MetalsPhysical: tailings spills; habitat fragmentation. Transition: closure bonds, access restrictionsFreshwater, terrestrial ecosystems, marine (offshore)Biodiversity Footprint Factor score, Protected Area proximity (km), restoration area committed
Oil & GasPhysical: spill impacts. Transition: stranded assets, deforestation regulations in upstreamTropical forests, mangroves, wetlands, marineScope 1–3 land-use emissions, IUCN Red List proximity, ecosystem restoration investment ($M)

Retail & ConsumerTransition: supply chain deforestation regulation (EU Deforestation Regulation effective 2025)Tropical forests, agricultural soils, freshwaterCommodity traceability rate (%), certified sustainable sourcing (%), supplier TNFD readiness score

Food and Agriculture: The Highest-Dependency Sector

The food and agriculture sector has the highest nature dependency of any major industry — 92% of assessed companies show high or very high dependency on at least one ecosystem service, according to ENCORE benchmarks.

The sector simultaneously drives approximately 70% of global freshwater consumption and is responsible for 80% of deforestation globally, according to the UNEP FI TNFD final recommendations analysis.

This bidirectional exposure — high dependency and high impact — means food companies face both physical and transition risk vectors simultaneously.

Kao Corporation applied the TNFD LEAP framework to its palm oil and surfactant supply chains, identifying that the highest nature and biodiversity risk sat in Sumatra and Borneo sourcing regions.

The company maps supplier GPS coordinates against the IBAT (Integrated Biodiversity Assessment Tool) to screen for proximity to critical habitats and Key Biodiversity Areas.

This approach is directly replicable by any organisation with a commodity supply chain: obtain supplier coordinates, overlay with IBAT or similar spatial tools, and flag High-risk suppliers for enhanced due diligence under your supply chain risk management ISO 28000 programme.

Financial Services: Managing Nature Risk Across the Portfolio

ASN Bank’s 2023 LEAP pilot — the most cited financial institution case study — found that 65% of nature-related financial risk concentrated in agriculture, real estate, and energy.

The bank used ENCORE to screen its entire loan portfolio by NACE code, then overlaid geospatial data to identify which loans financed operations in high-biodiversity-risk areas.

The output drove a revised operational risk management framework for agricultural lending, with new covenants requiring nature and biodiversity risk disclosure from borrowers above a materiality threshold.

For financial institutions, nature and biodiversity risk assessment operates at two levels: the entity level (own operations) and the portfolio level (financed and invested activities).

Portfolio-level nature and biodiversity risk is measured primarily through financed nature impacts — the weighted average of counterparty nature impacts proportional to the institution’s financing share.

Bloomberg and MSCI have begun publishing nature scores at the company level, though data coverage remains uneven at approximately 40% of global listed equities.

Governance Design for TNFD Biodiversity Risk Under the Three Lines Model

TNFD’s Governance pillar requires clear assignment of nature risk oversight. The what is enterprise risk management Three Lines model maps cleanly: the first line (business units and operations) owns nature risk identification and day-to-day management;

The second line (risk function) owns the TNFD framework, methodology, and aggregate reporting; the third line (internal audit) provides independent assurance over disclosure accuracy and LEAP process integrity.

Set SBTN targets and track progressARCI

R = Responsible | A = Accountable | C = Consulted | I = Informed

The Risk Committee charter should be updated to include nature-related risk explicitly in scope alongside climate, operational, and strategic risk.

Board-level oversight should cover: (1) approval of the nature risk appetite statement and materiality threshold, (2) review of LEAP assessment outputs at least annually, (3) approval of TNFD-aligned disclosure content before publication.

The key risk indicators examples for nature risk should be reported to the Risk Committee on a quarterly basis, with breach thresholds triggering escalation to the Board.

Nature risk KRIs should be early-warning signals, not lagging outcome measures. Useful leading KRIs for the how to develop key risk indicators dashboard include: deforestation rate in supplier geographies (monthly satellite feed)

Freshwater stress index at key operational sites (AQUEDUCT risk score, quarterly), regulatory news score for EU Deforestation Regulation enforcement (monthly), and percentage of supply chain tier-1 suppliers with TNFD-aligned disclosures (semi-annual).

Integrating SBTN: From TNFD Biodiversity Risk Assessment to Science-Based Targets

Completing the LEAP assessment is the risk management half of the nature and biodiversity risk equation. Setting Science Based Targets for Nature (SBTN) — the nature equivalent of SBTi climate targets — is the strategy half.

TNFD and SBTN share the same vision: a nature-positive economy by 2030. The two frameworks are intentionally designed to interoperate: LEAP provides the evidence base (what the risks and impacts are), and SBTN provides the target-setting methodology (what the organisation commits to do about them).

SBTN targets follow a five-step methodology (Assess, Interpret, Measure, Set, Act and Track) aligned with the AR3T framework — Avoid, Reduce, Restore, Transform, and advocate for systemic change.

As of February 2025, the SBTN validation services are open, with expanded land targets, marine, and freshwater methods expected in 2025–2026.

An organisation that completes LEAP A3 (financial materiality assessment) has the input data required to begin SBTN’s Step 1 (Assess) immediately — the two frameworks share geographic exposure data, ecosystem service dependencies, and impact pathways.

The governance link matters: SBTN targets must be validated externally before they are disclosed as ‘science-based.’

Disclosing nature and biodiversity risk targets without SBTN validation exposes the organisation to greenwashing risk — exactly the failure mode that led to over 40 EU Corporate Sustainability Reporting Directive enforcement actions in 2024 related to unsubstantiated biodiversity claims.

Pair your compliance risk assessment framework with a SBTN target validation timeline to close this gap.

TNFD Biodiversity Risk Metrics: Cross-Sector and Sector-Specific KRIs

TNFD’s Metrics and Targets pillar requires disclosure of cross-sector metrics (applicable to all organisations) and sector-specific metrics (drawn from industry-specific guidance).

The identifying risk metrics process for TNFD follows the same design principles as any KRI programme: each metric must have a baseline, a target, a threshold, and an owner.

MetricCategoryMeasurement UnitData Source
Land use and ecosystem conversionCross-sectorHectares (ha) converted from natural habitatSatellite imagery; GIS; supplier declarations
Freshwater consumption and withdrawalCross-sectorCubic metres (m³) per yearWater meter data; AQUEDUCT Water Risk Atlas
GHG emissions from land-use changeCross-sectortCO2e per yearIPCC emission factors; supplier data
Biodiversity Footprint Factor (BFF)Cross-sectorSpecies loss per year (PDF·m²·yr)GLOBIO model; ENCORE API

Deforestation-linked supply chain (%)Retail / Consumer sector% of commodity volume sourced from deforestation-risk geographiesTrase.Earth; CDP Forests; supplier audits
Nature-aligned AUM (%)Financial Services sector% of AUM screened for nature riskENCORE portfolio screening; MSCI Nature Score

The risk reporting importance and best practices principle of decision-utility applies directly to TNFD metrics selection: if a metric cannot change a management decision, it should not be disclosed.

Cross-sector metrics establish comparability; sector-specific metrics establish operational relevance.

A retailer that discloses only freshwater consumption without deforestation-linked sourcing rates has satisfied the letter of cross-sector requirements but missed the most material nature risk in its value chain.

Overcoming TNFD Biodiversity Risk Data Challenges: Tools and Workarounds

The most consistent objection practitioners raise to nature and biodiversity risk assessment is data availability.

Unlike carbon metrics — where supplier-reported Scope 3 data, even imperfect, provides a workable basis — biodiversity metrics require spatial data, ecosystem condition indices, and species-level indicators that many organisations simply do not hold.

The TNFD 2025 Status Report identified that while 89% of organisations intend to report nature information, fewer than 40% have sufficient baseline data for meaningful metrics disclosure. Here is how leading practitioners are bridging the gap.

Satellite data services have matured significantly. Planet Labs, Descartes Labs, and MapBiomas provide near-real-time land cover change detection at sub-hectare resolution globally.

Organisations with agricultural supply chains can use these services to monitor deforestation-linked sourcing geographies monthly — at a cost of USD 5,000–50,000 per year depending on coverage area, compared to the regulatory fines and reputational costs of non-disclosure.

The enterprise risk management technology infrastructure already in place for operational risk monitoring can be extended to consume satellite data feeds.

For portfolio-level screening, MSCI’s Nature Score and Bloomberg’s ESG biodiversity data provide company-level nature risk ratings for approximately 10,000 listed entities — roughly 40% of global equity market capitalisation.

ENCORE’s free API covers all 157 NACE sub-industries and provides a starting point for any organisation without access to premium data.

The World Resources Institute’s AQUEDUCT Water Risk Atlas is the standard free tool for freshwater stress scoring by location — it maps physical and regulatory water risk for over 189 countries and integrates directly into LEAP L1 screening for any operation with water-intensive processes.

The TNFD established the Nature-related Data Catalyst initiative to accelerate data innovation and methodological standardisation — outputs are expected in 2025–2026 and will materially improve the metrics landscape.

Double materiality assessment — required under CSRD’s ESRS E4 — is the most methodologically demanding element. It requires organisations to assess both financial materiality (how nature risks affect the company) and impact materiality (how the company affects nature).

The LEAP framework is ESRS-compliant for double materiality, but requires teams to gather biodiversity impact data not typically held in finance or risk systems.

A staged approach works: Year 1, complete financial materiality (LEAP L-E-A); Year 2, add impact materiality using third-party ecosystem condition data; Year 3, set SBTN-validated targets across both dimensions.

Frequently Asked Questions: Nature and Biodiversity Risk

What is the difference between TNFD and TCFD for biodiversity risk?

TCFD addresses climate-related financial risks — primarily through greenhouse gas emissions, carbon pricing scenarios, and physical climate hazards.

TNFD addresses nature-related financial risks — ecosystem degradation, biodiversity loss, freshwater stress, soil depletion, and land-use change.

Both use the same four-pillar governance architecture, making them stackable rather than competing.

TNFD explicitly states its framework should be used alongside TCFD, not instead of it, because climate change is one of five drivers of nature loss (alongside direct exploitation, land/sea use change, pollution, and invasive species).

An organisation running SEC climate disclosure rules ERM implications processes already has the governance infrastructure to add TNFD with incremental effort.

Is TNFD disclosure mandatory for US companies?

As of April 2026, TNFD disclosure is voluntary in the United States. However, two regulatory vectors are pushing it toward quasi-mandatory status.

First, the ISSB’s planned Exposure Draft by COP17 (October 2026) will establish an IFRS standard on nature risk that global financial institutions — including US multinationals with international capital market access — will need to comply with.

Second, the EU’s CSRD applies to non-EU companies with EU revenue exceeding €150 million and at least one EU subsidiary or branch — capturing a large segment of US multinationals.

Organisations conducting how to conduct a compliance risk assessment for CSRD should include ESRS E4 biodiversity in scope.

How long does a TNFD LEAP assessment take for a first-time organisation?

For a mid-sized organisation with one to three primary operating sectors and a defined geographic footprint, a first-cycle LEAP assessment typically takes 12–16 weeks: four weeks for L1 hotspot screening (ENCORE + internal GIS data).

Four weeks for E1-E3 dependency and impact evaluation (stakeholder interviews, supply chain data collection); four weeks for A1-A3 financial materiality quantification; two to four weeks for P1-P2 disclosure preparation and board review.

Organisations with complex, multi-tier supply chains or highly diversified geographic footprints should budget 20–24 weeks for the first cycle. Each subsequent annual cycle reduces to eight to twelve weeks as baseline data quality improves and the team builds methodology fluency.

TNFD’s official toolkit includes ENCORE (sector screening), IBAT — Integrated Biodiversity Assessment Tool (Protected Area proximity), the IUCN Global Ecosystem Typology (biome classification), and the GLOBIO model (biodiversity impact quantification).

Free public datasets include NASA’s MODIS land cover data, the AQUEDUCT Water Risk Atlas from the World Resources Institute, and Protected Planet from UNEP-WCMC — the authoritative database of globally protected areas and Key Biodiversity Areas.

Premium commercial platforms used by institutional investors include MSCI Nature Score, Moody’s ESG (formerly Four Twenty Seven), and MSCI TNFD solutions.

For financial institutions, the UNEP FI portfolio assessment methodology for nature provides specific guidance on operational risk management in banking Basel aligned with TNFD.

How does TNFD biodiversity risk assessment integrate with existing ERM frameworks?

TNFD nature risks should be integrated into the existing enterprise risk management framework rather than managed in a separate ESG silo.

This means: (1) adding nature risk categories to the risk taxonomy alongside credit, operational, strategic, and reputational risk; (2) running LEAP alongside the existing annual risk assessment cycle; (3) including nature KRIs in the key risk indicators template reported to the Risk Committee; and (4) updating the risk appetite statement to include nature materiality thresholds.

The COSO ERM 2017 framework’s principle of portfolio view of risk explicitly accommodates non-financial risk categories, making integration with COSO framework guide to internal controls straightforward.

What is the relationship between TNFD and the Kunming-Montreal Global Biodiversity Framework?

The Kunming-Montreal Global Biodiversity Framework (GBF), adopted at COP15 in December 2022, set the global political target: 30×30 (30% of land and ocean protected by 2030) and mandatory nature-related risk disclosure for large companies by 2030 under Target 15.

TNFD is the voluntary market framework designed to deliver Target 15. SBTN’s science-based targets align corporate ambition with GBF national targets.

In practice, an organisation that completes TNFD LEAP, sets SBTN-validated targets, and discloses under the four-pillar framework is demonstrating alignment with GBF Target 15 — which is precisely what regulators in the EU, UK, Canada, and Japan are asking for in their respective sustainability disclosure regimes.

How should SMEs approach TNFD biodiversity risk without large sustainability teams?

SMEs are not yet subject to mandatory TNFD disclosure, but three pathways make early engagement rational. First, large corporate customers subject to CSRD’s ESRS E4 will require Scope 3 nature data from suppliers — SMEs that do not prepare will face supply chain qualification risk.

Second, sustainable finance products (green loans, sustainability-linked bonds) increasingly require TNFD-aligned borrower disclosures.

Third, regulators in the UK (aligned with TNFD) and Japan (FSA guidance) are extending scope progressively.

A proportional SME approach: use ENCORE for a two-hour sector screening; identify the top two nature risks from the results; run a simplified LEAP L1-E1 assessment using free tools; disclose qualitatively in the first year and add metrics in Year 2.

Link findings to your existing risk management process flow chart to avoid standalone reporting.

What are TNFD biodiversity risk scenarios and how do we run them?

TNFD scenario analysis examines how different nature futures affect the organisation’s financial performance and strategy resilience.

The NGFS and TNFD joint nature scenarios provide four reference scenarios ranging from orderly transition (early policy action, nature protected) to disorderly (late, disruptive policy) and hot house world (failed transition, severe biodiversity loss).

For each scenario, organisations model the financial impact on revenue (ecosystem service disruption), costs (compliance, restoration), and capital availability (investor and lender nature risk pricing).

The scenario outputs feed the Strategy pillar’s disclosure on business model resilience — the same narrative structure used for climate scenario analysis under SEC climate disclosure rules ERM implications.

Common Pitfalls in Nature and Biodiversity Risk Implementation

PitfallRoot CauseRemedy
Running LEAP as a compliance exercise rather than a nature and biodiversity risk assessmentSustainability team leads with disclosure objective, not risk identificationAnchor LEAP in the Risk function; use output to populate the enterprise risk register before preparing disclosure
Stopping at hotspot screening without financial quantificationOrganisations complete LEAP L and E but treat LEAP A as optionalMandate financial materiality quantification (likelihood × revenue-at-risk) for every High-rated dependency and impact — this is what boards and investors require
Disclosing biodiversity targets without SBTN validationMarketing teams set ‘nature-positive by 2030’ goals without evidence baseNo quantitative targets should be disclosed until SBTN validation is in progress; use qualitative commitments with timeline until validated
Fragmenting nature risk into an ESG silo separate from ERMESG team manages TNFD independently of Risk CommitteeIntegrate nature risk taxonomy into the corporate risk register, risk appetite statement, and board risk reporting from Day 1
Using global average emission factors for biodiversity footprint calculationsData teams substitute activity-level data with generic benchmarksSite-specific GPS coordinates are non-negotiable for LEAP L1; location data drives every downstream metric — prioritise spatial data collection over metric breadth
Ignoring supply chain tier-2 and tier-3 nature riskLEAP scope limited to own operations onlyMost nature risk in consumer-facing industries sits in agricultural supply chains — use the EU Deforestation Regulation supplier traceability requirements as a forcing function for tier-2 data collection
Treating TNFD and CSRD as separate workstreamsSiloed compliance teams managing different regulatory frameworksThe LEAP framework is CSRD ESRS E4 compliant — run one assessment that satisfies both, coordinated by a cross-functional governance team covering risk, legal, finance, and sustainability

Looking Ahead: TNFD Biodiversity Risk 2025–2027

The next 24 months will define whether nature risk moves from voluntary leadership to mandatory baseline.

The ISSB’s Exposure Draft on nature-related financial disclosures, targeted for COP17 in October 2026, will establish the IFRS standard that jurisdictions globally — including the UK, Canada, Japan, and progressively the EU — are expected to adopt or align with.

When finalised, organisations that have completed TNFD LEAP assessments will have a two-to-three year head start in data quality and methodology maturity over late adopters.

The convergence of risk oversight with strategic planning principle has never been more directly applicable: nature risk strategy is becoming capital markets strategy.

SBTN is expanding its methods through 2025–2026 to cover marine targets, expanded land targets, and additional freshwater pollution sources.

These additions will make SBTN validation increasingly accessible to sectors that currently lack marine or freshwater sub-methodologies.

Simultaneously, the EU Deforestation Regulation — which entered its enforcement phase in 2025 — is creating the de facto mandatory supply chain traceability infrastructure that TNFD’s LEAP L1 requires.

Companies investing in supplier GPS coordinate collection for EUDR compliance are simultaneously building the nature and biodiversity risk data foundation at no incremental cost.

Data quality is the constraint most likely to improve fastest. The TNFD Nature-related Data Catalyst initiative, satellite data cost curves following Moore’s Law, and the IUCN’s ongoing Global Ecosystem Typology updates are all converging to reduce the cost and increase the accuracy of nature metrics.

By 2027, the combination of improved biodiversity footprint modelling tools, ISSB-mandated standardised metrics, and mandatory supply chain traceability will close most of the data gaps that currently make nature and biodiversity risk assessment resource-intensive.

Organisations that build the best ESG reporting software compared 2026 integration now will scale into mandatory reporting without a system rebuild.

The competitive dynamics are shifting. ASN Bank, Santander Peru, Kao, Suntory, and the 730+ early adopters are building institutional knowledge that late movers will pay consultants to acquire under time pressure.

The organisations that will struggle most in 2027 are not those with the most complex nature exposures — it is those that have not started the LEAP journey and face regulatory deadlines without baseline data, methodology experience, or board-level literacy on nature and biodiversity risk management.
