TNFD’s new research confirms the financial materiality of nature-related risks, providing a pivotal climate risk disclosure tool for corporate sustainability. ESG BROADCAST shares key takeaways.
The Taskforce on Nature-related Financial Disclosures (TNFD), in collaboration with the University of Oxford’s Environmental Change Institute and Global Canopy, has released new research affirming the financial materiality of nature-related risks. Published during London Climate Action Week, the report is a consolidated review of over 600 evidence pieces from 360 sources including peer-reviewed studies, company reports, and stakeholder interviews. Alongside the paper, TNFD issued finalised sector-specific guidance for water utilities and a joint set of business case studies developed with the Global Reporting Initiative (GRI), showcasing how corporates identify nature-related risks and opportunities based on their dependencies and impacts on natural ecosystems.
Drawing on multidisciplinary evidence, the research finds extensive proof that nature degradation—through loss of biodiversity, ecosystem collapse, or resource scarcity—can significantly affect corporate cash flows, access to capital, and insurance exposure. It also warns of systemic risks to the global financial system if such dependencies are not transparently assessed and managed. However, the report also notes a current lack of consistent nature risk assessment practices at the company level, underlining a major gap in climate policy disclosure regimes.
The objective of the research is fourfold: to improve understanding of how nature-related risks manifest financially; to identify data and analytical gaps; to share lessons learned by corporates and financial institutions; and to provide actionable recommendations for companies, data providers, and regulators. The accompanying database on nature-related financial risks has been opened to public consultation until 31 December 2025 to gather additional input and validate the research’s robustness.
The TNFD argues that integrated risk assessments, scenario planning, and better availability of nature-linked datasets are critical to futureproofing business models in a nature-declining world. The report serves as an essential knowledge base to inform disclosures under the TNFD framework, which is gaining traction alongside its climate counterpart, the TCFD.
Niki Mardas, Executive Director of Global Canopy, underscored the strategic threat posed by ecosystem degradation, noting how it amplifies physical risks such as wildfires, droughts, and floods, with cascading impacts on the insurance sector and asset valuation. Professor Nicola Ranger from the London School of Economics characterised the findings as a wake-up call, stating, “Nature is about foundational ecosystem services—water, food, raw materials. This research shows that nature loss is a material financial risk.”
Strategic significance lies in the growing expectation that companies will be held accountable for both their impacts on nature and their dependencies, especially as investors increasingly demand transparent ESG compliance. This development reinforces the case for integrating nature metrics into sustainability reporting and for aligning financial decision-making with ecological boundaries. The paper provides a critical knowledge link for firms preparing TNFD-aligned disclosures and regulators seeking to craft robust biodiversity-related disclosure requirements.
