The Taskforce on Nature-Related Financial Disclosures (TNFD) framework helps asset owners identify, assess, and disclose nature-related risks and opportunities in their portfolios. It provides standardized guidance for measuring dependence on and impact to natural capital, enabling institutional investors to integrate biodiversity and ecosystem health into investment decision-making and governance.

It provides standardized guidance for measuring dependence on and impact to natural capital, enabling institutional investors to integrate biodiversity and ecosystem health into investment decision-making and governance.
Nature-related financial risk has moved from corporate responsibility messaging into fiduciary territory. The Dasgupta Review (2021), commissioned by the UK Treasury, quantified ecosystem services at $125 trillion annually—a figure that underscores why institutional asset owners cannot treat biodiversity loss as a compliance checkbox. The World Economic Forum's 2024 Global Risks Report ranked nature loss as the second-highest global risk by potential impact, alongside artificial intelligence concerns. For asset owners managing $191 trillion globally (PwC Global Asset Management Survey, 2024), this shift demands integration into core investment processes.
How does TNFD translate climate governance structures into nature-related frameworks?
TNFD adopts the four-pillar architecture of the TCFD (Task Force on Climate-related Financial Disclosures), which successfully mainstreamed climate disclosure over the past decade. However, nature-related financial risk operates differently from climate risk. While carbon emissions are additive, globally fungible, and measurable through a single metric (CO2 equivalent), nature risk is place-based, non-linear, and multidimensional.
The TNFD framework's four pillars—Governance, Strategy, Risk Management, and Metrics & Targets—require institutional adaptation:
Governance demands that investment committees and boards establish explicit accountability for nature-related financial risks. This mirrors climate governance but extends beyond carbon specialists. It requires nature literacy across portfolio managers, researchers, and due diligence teams. Governance implementation begins with board-level sponsorship and integration into CIO mandates. The California Public Employees' Retirement System (CalPERS), with $533 billion AUM, has begun embedding nature-related stewardship into its governance framework, including shareholder engagement templates addressing water security and deforestation risk.
Strategy requires asset owners to embed nature dependencies into investment theses and portfolio construction. Unlike climate scenarios, which rest on emissions trajectories and carbon pricing, nature strategy must account for localized ecosystem collapse, regulatory tightening around land-use practices, and supply chain disruption. The framework asks: Which ecosystem services does our portfolio depend upon? In which geographies do we face highest nature-related transition risk? What capital reallocation does this demand? The Norwegian Government Pension Fund Global (Norges Bank Investment Management), managing $1.4 trillion, has integrated nature-related exclusions and engagement into its responsible investment framework, divesting from companies with unacceptable impacts on biodiversity.
Risk Management integrates nature-related assessment into due diligence, underwriting, and ongoing monitoring. This typically involves extending existing ESG questionnaires to capture nature dependencies, identifying which portfolio companies operate in biodiversity hotspots, and assessing supply chain exposure to deforestation, water stress, or soil degradation. Asset owners often use third-party data providers (Orbia, Spatial Finance, Refinitiv) to overlay holdings against satellite-mapped ecosystem services and biodiversity conservation priorities. Private equity and real estate managers must conduct ecosystem impact assessments before acquisition, mirroring environmental due diligence practices but with forward-looking transition planning.
Metrics & Targets establish quantifiable KPIs for nature outcomes. These differ fundamentally from carbon reduction targets. Nature metrics require baseline mapping of portfolio exposure to specific ecosystems and species, measurement of portfolio impact on biodiversity (land use intensity, freshwater consumption, pollution load), and alignment with science-based targets. The Science Based Targets initiative (SBTi) launched a Nature Guidance framework in 2024 to help companies set credible biodiversity targets. Asset owners increasingly incorporate nature KPIs into investment manager mandates, making nature performance a component of performance fees.
What does portfolio-wide natural capital dependency mapping require?
Natural capital dependency mapping is the operational foundation of TNFD implementation. Asset owners must identify which holdings depend on ecosystem services and quantify exposure concentration.
The framework identifies five principal ecosystem services relevant to investment portfolios: freshwater availability, pollination and crop protection, climate and weather regulation, soil quality and formation, and coastal protection. Sectors with high dependency include agriculture (freshwater availability), pharmaceuticals (genetic resources), energy infrastructure (water for cooling), and real estate (flood and drought risk). Mining and extractives depend on stable water systems and face transition risk from climate and water regulation.
Mapping begins with sector-level analysis. A large institutional investor with diversified holdings identifies which sectors face elevated nature risk. Agricultural commodity exposure—whether direct holdings or through food processors and retailers—carries dependence on pollination, soil health, and freshwater availability. Holdings in mining and construction face biodiversity offset requirements and supply chain fragility from water stress. Financial services and insurance are indirectly exposed through credit portfolios and underwriting risk.
The second phase involves geographic concentration mapping. Biodiversity hotspots and water-stressed basins overlap unevenly with portfolio holdings. Asset owners layer holdings data against global biodiversity indices (the Biodiversity Intactness Index, which measures the relative loss of species and ecological processes), watershed maps, and deforestation risk models. This reveals concentration risk: a portfolio may have significant exposure to companies dependent on the Amazon or Southeast Asian forests, or operating in India's water-stressed river basins.
Third, asset owners assess supply chain exposure. A holding's direct operations may have low nature impact, but supply chains may be embedded in high-risk geographies. A beverage manufacturer's direct footprint may be manageable, but its agricultural supply chains face water stress and soil degradation in key sourcing regions. This requires granular supply chain mapping, often through primary research with portfolio companies or third-party supply chain databases.
Data challenges are acute. While large multinational corporations increasingly disclose water consumption and agricultural sourcing regions, private companies, emerging market holdings, and small-cap positions often lack detailed nature disclosure. Asset owners address this through tiered approaches: comprehensive analysis for high-impact holdings, sector-level assumptions for smaller positions, and engagement to improve disclosure. The Principles for Responsible Investment (PRI) membership network, representing $150+ trillion in assets, has published TNFD implementation guidance emphasizing proportionality—starting with material holdings and sectors rather than attempting portfolio-wide precision immediately.
Why does nature transition risk require different governance from climate governance?
Climate governance, now embedded in most large asset owner frameworks, focuses on emissions reduction and carbon pricing. Nature governance must account for place-based, sectoral, and regulatory complexity that defies single-metric management.
Climate risk operates on global carbon budgets: a ton of CO2 avoided anywhere contributes equally to global climate stability. Nature risk is fundamentally local. Biodiversity conservation in Southeast Asia does not offset deforestation in the Amazon. Water conservation in one watershed does not address scarcity in another. This geographic specificity demands decentralized governance: investment committees cannot manage nature risk through a single carbon-equivalent lens. Sector teams and regional specialists must integrate nature considerations into their theses.
Regulatory fragmentation accelerates this complexity. The European Union's Corporate Sustainability Reporting Directive (CSRD) mandates nature disclosure for large portfolio companies from 2025, with financial materiality assessment required. Brazil's environmental regulations are tightening around Amazon deforestation, creating transition risk for agricultural and energy holdings. Australia's Nature Positive Commitments framework and Singapore's sustainable finance roadmap signal regulatory convergence, but the pace and stringency differ. Asset owners must navigate jurisdiction-specific regulation while maintaining consistent risk frameworks—a governance challenge that climate governance, with its global carbon pricing narrative, has simplified.
Supply chain complexity also distinguishes nature governance. A portfolio company's carbon footprint can be measured through Scope 1, 2, and 3 emissions accounting (a standardized methodology). Nature impact assessment requires understanding ecosystem dependence at every point in value chains, where data transparency is inconsistent and attribution is ambiguous. A food company's water risk depends on the hydrology and regulatory environment of its sourcing regions, not just its operational footprint. This demands supply chain transparency and supplier engagement that many asset owners are still building capacity for.
How should asset owners sequence TNFD implementation?
Institutional implementation generally follows three phases, with proportionality built in for portfolio complexity and asset class.
Phase One: Materiality Assessment and Governance Foundation. Asset owners conduct materiality analysis identifying which sectors, geographies, and nature-related issues pose highest financial risk to their portfolio. This mirrors ESG materiality frameworks but focuses on nature dependencies and impacts. The investment committee establishes oversight responsibility, designates a nature risk sponsor, and updates investment policy statements to include nature-related risk management. This phase typically requires three to six months for institutions managing $50 billion or above. Governance updates should specify which portfolio companies will receive enhanced nature-related due diligence, and which investment managers will be required to disclose nature KPIs. This foundation should leverage existing Investment Committee Governance: Best Practices for Asset Owners frameworks while adding nature-specific accountability.
Phase Two: Portfolio Mapping and Risk Assessment. Using materiality findings, asset owners map natural capital dependencies across material holdings and sectors. This involves data procurement (from providers like Orbia, Spatial Finance, or World Resources Institute), primary research with portfolio companies, and creation of nature risk dashboards. Many asset owners extend ESG questionnaires to capture nature-related data. Private equity and real estate managers conduct ecosystem impact assessments on target investments. This phase is data-intensive and typically spans six to twelve months. Small-cap and emerging market holdings may use sector-level assumptions rather than company-specific mapping, reflecting data availability. Risk assessment translates dependency mapping into financial impact scenarios: How would a regulatory tightening on agricultural emissions affect crop sector valuations? What capital expenditure would be required if a utility faces increased water restrictions?
Phase Three: Integration into Investment Processes and Target-Setting. Asset owners embed nature risk into ongoing investment manager oversight, performance mandates, and engagement programs. Nature KPIs are incorporated into investment manager contracts, comparable to existing ESG metrics. Engagement teams develop stewardship priorities addressing nature risk for material holdings. Asset owners set science-aligned biodiversity targets, often aligned with the SBTi Nature Guidance framework. Disclosure frameworks are refined to meet regulatory requirements (CSRD for European-exposed portfolios, and emerging requirements in other jurisdictions). This phase is iterative and typically begins six months into Phase Two.
The sequencing reflects capacity constraints: few asset owners have deep nature expertise in-house, requiring external partnerships and gradual team development. The Principles for Responsible Investment (PRI) has published implementation resources that many asset owners use to structure this progression.
What specific TNFD disclosures should asset owners prepare for regulatory environments?
Regulatory disclosure requirements are emerging unevenly across geographies, creating complexity for global asset owners.
The European Union's Corporate Sustainability Reporting Directive (CSRD) mandates that large companies disclose nature-related impacts from 2025, with financial materiality assessment. This cascades to asset owners through portfolio company disclosure requirements and, increasingly, demands that asset owners demonstrate engagement and stewardship on nature issues affecting material holdings. EU-regulated investment firms will face expectations to align with the EU Taxonomy framework's environmental objectives, which include biodiversity protection and restoration. This creates pressure to demonstrate portfolio alignment with nature-positive outcomes.
The United Kingdom's Financial Conduct Authority (FCA) has signaled forthcoming nature-related disclosure expectations for large financial institutions, likely within 2025. Australia's Treasury is developing Nature Positive Commitments guidance that will affect institutional investors with material Australian equity exposure. Singapore's Monetary Authority is incorporating nature risk into its prudential framework. China's environment ministry has issued guidance on environmental information disclosure for listed companies, beginning to surface nature-related data into financial markets.
For asset owners, disclosure preparation involves three elements:
- Regulatory Inventory. Identify all regulatory jurisdictions affecting portfolio companies and investor obligations. EU exposure triggers CSRD alignment requirements; UK exposure may trigger FCA disclosures; Australian and Asian holdings face jurisdiction-specific guidance.
- Portfolio Company Engagement. Asset owners should ensure material portfolio companies have commenced TNFD implementation. This involves shareholder engagement, proxy voting on nature-related governance proposals (particularly for companies in high-impact sectors), and supplier engagement programs addressing scope 3 nature risks.
- Asset Owner Disclosure. Larger asset owners (particularly those regulated under the EU's sustainable finance regime or with significant EU pension fund investors) should prepare voluntary nature disclosures using TNFD frameworks. This demonstrates sophistication and mitigates fiduciary risk. Disclosures should address governance of nature-related issues, material nature-related risks in the portfolio, scenario analysis of nature transitions affecting key holdings, and metrics tracking portfolio progress toward nature-positive outcomes.
The disclosure landscape is evolving rapidly. Asset owners should treat current TNFD guidance as a floor—likely to become a regulatory ceiling once jurisdictions formalize requirements.
How does nature-related risk integrate with existing investment themes?
Nature-related risk increasingly overlaps with established investment frameworks that asset owners are already monitoring.
