Nature-related financial risk encompasses the material economic impacts on asset values, cash flows, and portfolio performance that arise from ecosystem degradation, biodiversity loss, water scarcity, soil depletion, and land-use change. These dependencies affect company valuations, supply chains, and the real economy's productivity across agriculture, consumer goods, utilities, and extractive sectors. Institutional investors increasingly recognize nature risk as a distinct fiduciary concern separate from—though complementary to—climate financial risk.

Institutional investors increasingly recognize nature risk as a distinct fiduciary concern separate from—though complementary to—climate financial risk.
Why is nature risk a financial concern, not just an environmental one?
The distinction matters. Environmental degradation becomes financial risk when it impairs the productive capacity of companies or undermines collateral values. A factory dependent on freshwater faces operational interruption if aquifers deplete. A food manufacturer sourcing from monsoon-dependent regions faces margin compression if rainfall patterns destabilize. A bank's mortgage portfolio depreciates if coastal properties face accelerating flood exposure from ecosystem collapse—independent of sea-level rise.
The World Economic Forum's Global Risk Report 2024 ranked biodiversity loss and ecosystem collapse as the third-highest global risk by economic impact over the next decade. The Dasgupta Review on the Economics of Biodiversity, commissioned by the UK government, estimated that nature loss represents a USD 2-5 trillion annual economic externality—making it comparable in magnitude to climate change. Yet nature risk has historically lacked the regulatory attention and quantitative frameworks that climate change financial risk has attracted.
This asymmetry is closing. Institutional allocators, fund managers, and boards now face governance pressure to articulate how they are identifying and managing nature risk within their fiduciary mandates. For long-term capital owners—pension funds, sovereign wealth funds, endowments—the timeline matters: nature degradation compounds over decades, and portfolio holdings lock in exposure to ecosystems that may collapse or become severely stressed within the investment horizon.
How does nature risk differ from climate risk?
The two are related but distinct. Climate risk involves emissions, physical hazards (flooding, heat stress), and transition pathways (fossil fuel stranding, renewable energy economics). Nature risk involves the integrity of natural systems: forests, freshwater, soil, fisheries, coral reefs, pollination ecosystems. A company can face severe climate risk with low nature risk; equally, a company can depend heavily on nature but generate minimal emissions.
Consider a large aquaculture producer. It may have low greenhouse gas emissions relative to terrestrial animal agriculture (addressing climate risk), yet face acute nature risk if coastal ecosystems—mangrove forests, seagrass beds, coral—are degraded. Mangrove loss reduces coastal protection and increases disease risk in farmed fish. Seagrass decline degrades water quality. These are nature risks with direct operational and financial consequences.
Conversely, a renewable energy manufacturer may help address climate risk but source minerals—cobalt, nickel, lithium—from regions where mining is degrading watersheds and endangering species. The climate contribution doesn't eliminate the nature risk embedded in the supply chain.
This complexity is why the Taskforce on Nature-related Financial Disclosures (TNFD), a UN-convened initiative with participation from the financial sector, developed its own framework. Like TCFD for climate, the TNFD provides structured guidance for companies and investors to identify, measure, and disclose nature-related financial dependencies and impacts. The final recommendations, released in September 2023 with anticipated adoption beginning in 2024, establish a common vocabulary and analytical architecture separate from climate frameworks.
Which sectors and companies face the highest nature-related financial risk?
Agriculture and food production face acute exposure. The sector depends on soil health, pollination services, freshwater, and stable growing conditions. A droughts-stressed region or a collapse in bee populations directly threatens yields and input costs. Nestlé, which sources cocoa, coffee, milk, and plant-based ingredients globally, explicitly identified freshwater stress, soil health, and deforestation as material financial risks in its TNFD beta disclosures. The company sourced cocoa from West Africa (exposed to deforestation and water stress) and dairy from regions facing groundwater depletion.
Consumer goods companies—Unilever, Procter & Gamble, Danone—derive significant margin from agricultural commodities and face cascading supply-chain risk. Apparel manufacturers depend on cotton production (water-intensive, often from regions with aquifer stress) and increasingly face pressure from regulatory restrictions on water-intensive dyes and textile processing.
Utilities, especially water and power companies, depend directly on hydrological stability. European utilities face increasing summer water scarcity; Indian power plants have experienced fuel supply disruption from river floods affecting coal transport. Pharmaceutical companies depend on biodiversity: roughly 25% of modern pharmaceuticals derive from plant sources, yet tropical forest cover loss continues at scale.
Extractive industries—mining, oil and gas—face nature risk both in operations (water availability, biodiversity regulations, tailings management) and in stranded-land dynamics: regulatory pressure to protect remaining ecosystems may restrict exploration in biodiverse regions.
Financial institutions themselves face nature risk through collateral valuation. A mortgage on agricultural land in a water-stressed region may depreciate as productive capacity declines. Coastal real estate faces collateral risk from mangrove loss and wetland degradation, independent of climate-driven sea-level rise.
What frameworks and metrics are emerging for nature risk assessment?
The TNFD framework, released in its final form in September 2023, provides a disclosure architecture modeled on TCFD. It structures disclosure around governance, strategy, risk management, and metrics—allowing investors and companies to articulate exposure to nature-related financial risks in standardized language. The framework identifies five key dependency and impact categories: water, land and ecosystems, marine and coastal ecosystems, atmospheric composition, and soil health.
The Natural Capital Protocol, developed by the Natural Capital Coalition, allows companies to quantify ecosystem service dependencies in physical and monetary terms. A food company, for instance, can map its reliance on pollination services, freshwater, and soil nutrient cycling, then assign monetary values to disruption scenarios.
The System of Environmental-Economic Accounting (SEEA), endorsed by the UN and integrated into national accounting standards, standardizes measurement of natural capital stocks and flows. Several countries now report natural capital accounts alongside GDP, revealing depletion of forests, fisheries, and minerals that traditional accounting masks.
Institutional investors have begun adopting these frameworks operationally. CalPERS, the California Public Employees' Retirement System (USD 440 billion AUM), committed in 2023 to incorporating nature risk into investment policy and stewardship. The Norwegian Government Pension Fund Global (USD 1.3 trillion), already a leader in climate risk integration, published guidance on nature-related dependencies and began mapping exposure across its equity and fixed-income portfolios.
The gap remains large: most asset managers lack standardized tools for portfolio-wide nature risk quantification, and corporate disclosure on nature dependencies remains sparse outside sustainability reports. But the regulatory and governance trajectory is clear. The European Union's Corporate Sustainability Directive will mandate TNFD-aligned disclosures starting in 2025 for large EU companies. The SEC is considering whether to require nature-related risk disclosures in the U.S. market. This regulatory momentum will accelerate institutional adoption.
What are the governance and stewardship implications for asset owners?
From a fiduciary capitalism perspective, asset owners—pension funds, endowments, insurance companies, sovereign wealth funds—have fiduciary duties to identify and monitor material risks. Nature risk increasingly meets that threshold. A CIO managing a 20-year-horizon pension fund must recognize that nature degradation happening today will impair cash flows and valuations of portfolio companies tomorrow. Unpriced nature risk represents a hidden liability.
This creates several governance obligations. First, boards and investment committees must develop competence in nature risk assessment. This requires training distinct from climate risk frameworks, though complementary. Second, stewardship practices—proxy voting, engagement, monitoring—must extend to nature dependencies. Stewardship in investing has historically focused on governance and financial performance; it now must include management of ecosystem dependencies.
Some institutional investors are beginning to deploy capital toward natural capital regeneration. Family offices and foundations have established dedicated investment vehicles in forest conservation, freshwater restoration, and sustainable agriculture. The Ecosystem Integrity Fund and similar vehicles offer institutional investors exposure to nature restoration as both financial and impact instruments. However, this remains a nascent allocation category.
Third-party service providers—proxy advisors, ESG data firms, engagement consultants—are developing nature risk tools, but maturity varies. An asset owner evaluating managers should assess not only climate risk competence but nature risk awareness and capability.
For long-term allocators, the implications are straightforward: incorporate nature risk into investment policy and manager selection now, ahead of regulatory mandates and market repricing.
