Assess: Risks and Opportunities
Translating ecology into financial risk
The Assess phase converts the dependency and impact findings from Evaluate into financially relevant risk and opportunity statements. It is here that nature science meets corporate risk management, asking: how do ecosystem changes translate into consequences for business strategy, operations, and financial performance?
The Risk Taxonomy: Three Types of Nature-Related Risk
The TNFD adopts a three-part risk taxonomy that mirrors, and extends, the approach developed for climate risk by the TCFD. These three risk types apply across different time horizons and through different transmission channels, and their interaction can create compounding effects that are more severe than any single category in isolation.
| Risk Type | Definition | Example | Time Horizon |
|---|---|---|---|
| Physical | Direct impacts from ecosystem degradation on business operations, supply chains, or asset values | Water scarcity reducing manufacturing output; loss of pollinators cutting agricultural yields | Near to medium term; some already materialising |
| Transition | Risks arising from societal responses to nature loss, including regulatory changes, market shifts, and changing consumer preferences | New deforestation regulations blocking market access; investor exclusions of high-deforestation commodities | Medium to long term; policy pipeline increasingly visible |
| Systemic | Risks arising from the breakdown of natural systems that underpin economic stability at a macro level | Collapse of ocean fisheries affecting food security; widespread soil degradation reducing agricultural productivity globally | Long term; potentially irreversible |
Physical Risk: Ecosystem Degradation as Business Risk
Physical nature risks arise when the ecosystems that a business depends on deteriorate to the point that they deliver fewer or lower-quality services. This is distinct from climate physical risk, though the two often interact. A drought-prone region suffering from both climate change and historical deforestation (which reduces local water cycling) may experience water stress that is more severe than either driver alone would produce.
Key physical risk categories in the TNFD framework include:
- Water quantity and quality risk: Affecting industries from beverages and food processing to semiconductors and pharmaceuticals that require reliable, clean water inputs.
- Soil health and fertility degradation: Directly threatening agricultural productivity as topsoil loss and erosion reduce the land's capacity to support crops.
- Loss of pollination services: The global economic value of crop pollination by insects is estimated at USD 235-577 billion annually; decline in pollinator populations is an increasingly material risk for food companies.
- Coastal protection loss: Mangrove and coral reef degradation increases the exposure of coastal assets to storm surge and erosion, raising insurance premiums and infrastructure replacement costs.
- Fishery collapse: Overfished stocks reduce the raw material base for seafood companies and the food security of dependent coastal communities.
Transition Risk: Policy, Market, and Reputational Channels
Transition risks for nature are accelerating as governments implement the Kunming-Montreal Global Biodiversity Framework (KM-GBF), adopted at COP15 in December 2022. The KM-GBF's Target 15 specifically requires that large and transnational companies regularly monitor, assess, and disclose their risks, dependencies, and impacts on biodiversity. This policy direction is driving a wave of regulatory transition risk for businesses in nature-intensive sectors.
The main channels of transition risk include:
- Regulatory risk: New laws restricting access to natural resources, requiring environmental impact assessments, or mandating disclosure of nature-related issues. The EU Deforestation Regulation (EUDR) is an immediate example, requiring due diligence evidence that commodities are deforestation-free before they can be sold in the EU market.
- Market access risk: Retailers, procurement policies, and financial institutions increasingly screen for nature-related performance. Companies unable to demonstrate responsible sourcing risk losing contracts, credit facilities, or investment.
- Technology risk: New monitoring technologies such as satellite deforestation tracking, DNA-based traceability, and eDNA species detection are increasing transparency throughout supply chains, making it harder to obscure poor nature performance.
- Reputational risk: Civil society, media, and investor attention to corporate nature impacts can damage brand value and consumer loyalty, particularly for consumer-facing companies in food, apparel, and cosmetics.
The Transition Risk Ratchet
Unlike physical risk, which tends to build gradually as ecosystems degrade, transition risk can arrive suddenly and non-linearly. Regulatory transition risk works like a ratchet: once a government commits to a deforestation regulation or biodiversity disclosure mandate, the direction of travel is clear even if the exact timing and details remain uncertain. Companies that have built supply chain traceability and nature management systems in advance find transition costs manageable; those caught unprepared face concentrated disruption. The lesson from climate regulation is that early movers gain competitive advantage and shape the standards others must later follow.
Systemic Risk: When Nature Underpins the Economy
The most challenging category is systemic nature risk, which refers to risks that emerge from the degradation of the natural systems that underpin entire economies rather than individual businesses. The World Economic Forum's Global Risks Report consistently identifies biodiversity loss and ecosystem collapse among the top five global risks by impact over a ten-year horizon.
More than half of global GDP is estimated to be moderately or highly dependent on nature. When systemic tipping points are crossed, such as large-scale forest die-back, ocean acidification reaching coral reef collapse thresholds, or widespread insect population collapse, the economic consequences extend far beyond any single sector. Systemic risks are characterised by their potential irreversibility and their difficulty for individual companies to manage in isolation.
Nature-Related Opportunities
The Assess phase is not exclusively concerned with risk. TNFD explicitly requires organisations to identify nature-related opportunities alongside risks. These opportunities are real and growing, driven by both the need to restore degraded systems and the transition to more sustainable economic models.
Key opportunity categories include:
- Nature-based solutions (NbS) revenue: Companies developing products and services that restore or protect ecosystems, from agroforestry to habitat banking, can access new revenue streams including biodiversity credits and payments for ecosystem services.
- Supply chain resilience: Investing in sustainable sourcing and natural capital stewardship reduces long-term supply chain volatility, lowers raw material costs through improved yields, and builds supplier loyalty.
- Market differentiation: Products certified as deforestation-free, wildlife-friendly, or nature-positive command premium pricing in growing consumer segments and access to procurement programmes that screen for sustainability performance.
- Resource efficiency: Reducing reliance on ecosystem services through circular economy approaches, water recycling, and precision agriculture can lower input costs while simultaneously reducing nature impacts.
- Green finance access: Nature-positive companies have increasing access to sustainability-linked loans, green bonds, and biodiversity-focused investment funds, potentially at preferential rates.
Example: Risk and Opportunity Assessment for a Global Coffee Company
A major coffee roaster identifies, through the Assess phase, that its Arabica supply chain faces material physical risk from the convergence of climate warming and deforestation-driven pollinator decline in key growing regions of Ethiopia and Colombia. The same assessment identifies transition risk from the EU Deforestation Regulation requiring traceability evidence before 2025.
On the opportunity side, the team identifies that investing in shade-grown, agroforestry-based sourcing programmes in partnership with farmer cooperatives would simultaneously restore pollinator habitat, generate high-quality premium coffee eligible for price premiums of 20-30%, and build the traceability documentation needed for EUDR compliance. The nature risk assessment therefore directly informs a sourcing strategy decision that manages risk while capturing market opportunity.
Prioritising Risks and Opportunities for Disclosure
The output of the Assess phase is a prioritised set of material nature-related risks and opportunities, characterised by type (physical, transition, systemic), likelihood, potential financial magnitude, and time horizon. This prioritised inventory is the direct input to the Prepare phase and forms the substantive basis for TNFD Strategy pillar disclosures on risks and opportunities.
The Assess phase also feeds into scenario analysis, which the TNFD encourages as a tool for stress-testing strategy resilience against different nature futures. Scenarios might contrast a world with effective global biodiversity governance and ecosystem recovery against one of continued degradation, helping leadership teams understand which strategic choices are robust across multiple futures.
Key Takeaways
- 1The TNFD recognises three categories of nature-related risk: physical (ecosystem degradation directly affecting operations), transition (regulatory and market responses to nature loss), and systemic (breakdown of the natural systems underpinning the broader economy)
- 2Physical nature risks are already materialising in sectors dependent on water, pollination, soil health, and coastal protection - the economic value of pollination services alone is estimated at USD 235-577 billion annually
- 3The Kunming-Montreal Global Biodiversity Framework Target 15 is a key driver of transition risk, requiring large companies to disclose biodiversity-related risks and impacts
- 4The EU Deforestation Regulation (EUDR) represents a concrete and immediate regulatory transition risk for companies sourcing forest-risk commodities into EU markets
- 5Nature-related opportunities are significant and growing, spanning nature-based solution revenues, supply chain resilience, market differentiation, resource efficiency, and preferential green finance access
