TNFD disclosures & nature-related accounting

01Overview and value chain

Markers: [EC: Corporate Nature Reporting & CSRD | OECD: Environmental Risk Accounting | Regulator: EPA (US)]

The sector of nature-related risk disclosure based on the Taskforce on Nature-related Financial Disclosures (TNFD) frameworks is the infrastructural backbone of modern green finance and ESG auditing. It drives the transition from traditional, purely financial accounting to a multi-criteria “nature-positive” accounting system. By quantitatively evaluating business dependencies on ecosystem services (such as water supply, pollination, and soil stability) and their impacts on biodiversity degradation across the entire value chain, this system exposes previously hidden environmental externalities as direct financial risks. Methodologies like TNFD translate ecological metrics—like species loss or soil degradation—into financial risks, preventing supply chain disruptions and enabling investors to direct capital toward genuinely sustainable projects.

The key directions of TNFD disclosures & nature-related accounting are based on the LEAP approach:

1. Locate: Identifying the exact geographical coordinates of all production sites and raw material supply chains to map them against interactive zones of high biodiversity vulnerability and water stress.
2. Evaluate: Quantitatively calculating the degree to which a business depends on nature and how its operations impact local ecosystems (e.g., nitrogen runoff into river basins).
3. Assess: Modeling the translation of physical, reputational, and regulatory nature risks into tangible financial metrics, such as Value-at-Risk (VaR) or asset impairment.
4. Prepare & Disclose: Generating standardized, independently audited reports for public stock exchange disclosure and strategic decision-making to attract green capital.

Value chain levels

Cross-cutting technologies of the sector:

• Integrated Spatial Biodiversity Scoring: Automated GIS systems cross-referencing corporate assets with global databases (e.g., IBAT, WDPA) to pinpoint high-risk operations.
• Double Materiality AI Models: Algorithmic computation of how businesses impact nature and how nature loss creates financial liabilities.
• Satellite Machine Vision: AI algorithms analyzing Sentinel and Landsat imagery to detect minute deforestation events within a company’s deep supply chain.

02US

The United States is actively deploying nature-related risk disclosures through pilot projects led by major Wall Street investment banks and the expansion of SEC climate initiatives.

Wall Street TNFD Pilots, ESG Rating Agencies, GBCI Integration

• Investment Bank Initiatives: Major funds are adopting TNFD recommendations, mandating portfolio companies to disclose water scarcity and deforestation risks in their supply chains.
• MSCI & S&P Global Ratings: Leading ESG agencies are integrating TNFD metrics—such as supply chain biodiversity loss—into their scoring models, directly influencing stock valuations.
• GBCI Integration: Expanding real estate and infrastructure certification standards (SITES) to verify the minimization of negative impacts on local ecosystems by developers.

03CN

China is implementing advanced mandatory environmental disclosure requirements for public companies and pioneering the unique concept of Gross Ecological Product (GEP) accounting.

Gross Ecological Product (GEP), CSRC Mandatory Disclosures, Green Finance

• Gross Ecological Product (GEP): Provinces like Shenzhen and Hainan officially measure the market value of regional ecosystem services (clean air, water supply) alongside traditional GDP.
• CSRC Mandatory Disclosures: The securities regulator requires mandatory environmental risk disclosures for listed companies, spurring the adoption of nature-accounting IT platforms.
• CDB Green Standards: State banks utilize GEP metrics to evaluate the return on investment for ecological infrastructure projects, issuing preferential natural capital loans.

04EU

The European Union leads global nature accounting regulation, making biodiversity risk disclosure legally mandatory for thousands of corporations under the CSRD directive.

CSRD Mandate, ESRS E4 Biodiversity Standards, EFRAG Guidelines

• Strict CSRD Mandate: The directive forces over 50,000 large companies operating in the EU to publish detailed annual reports on their environmental impacts and dependencies.
• ESRS E4 Standard: Developed by EFRAG, this standard demands detailed spatial localization of assets near high-biodiversity areas and concrete transition plans to a Net Positive Impact model.
• Financial Penalties: Failure to provide accurate biodiversity data or engaging in hidden greenwashing triggers multi-million-euro fines and restricted access to European capital markets.

05Leading companies and research institutes

06Tech stack and innovations

The nature accounting industry relies on integrating geospatial databases, double materiality AI models, and satellite Earth observation systems.

1. Integrated Spatial Biodiversity Scoring (GIS Analysis):
   • Utilizes the Integrated Biodiversity Assessment Tool (IBAT), merging the IUCN Red List, WDPA, and Key Biodiversity Areas.
   • GIS servers automatically assign high-risk categories to physical assets (like mines or farms) located within close radii of vulnerable zones, adjusting their ecological value coefficients.
2. ENCORE Matrix and Double Materiality:
   • Developed by UNEP-WCMC, ENCORE features a digitized matrix linking 86 economic sectors with 21 ecosystem services.
   • Calculates specific dependency and impact indices, allowing financial modeling of a company’s revenue sensitivity to local ecological collapses (e.g., loss of pollinators).
3. Remote Sensing Deforestation Algorithms:
   • AI algorithms process radar and optical imagery from Sentinel-2 and Landsat to monitor Scope 3 supply chain compliance.
   • Convolutional neural networks (U-Net) recognize minute changes in canopy density, automatically matching deforestation zones with supplier boundaries registered in ERP systems.

Stage 1: GIS Supply Chain Mapping

A multinational corporation exports raw supplier addresses from its ERP system, translating thousands of farms and factories into precise GIS coordinates to generate a comprehensive Asset Spatial Map overlaying global deforestation databases.

Stage 2: LEAP Dependency Analysis

Coordinates are fed into the ENCORE and IBAT databases via API to conduct the Locate and Evaluate steps, identifying, for example, high extreme dependency on freshwater and uncovering supplier overlaps with Key Biodiversity Areas.

Stage 3: AI Modeling of Financial Scenarios

The Assess step is performed by AI systems utilizing NGFS methodology to model physical and regulatory risks, calculating the specific Value-at-Risk (VaR) representing potential multi-million dollar losses due to environmental degradation.

Stage 4: Net Positive Impact Strategy Development

Based on the risk analysis, the board approves a Net Positive Nature Impact Strategy, which includes terminating contracts with high-risk suppliers, funding local ecological restoration, and linking these KPIs to executive bonuses.

Stage 5: External ISAE 3000 ESG Audit

The draft TNFD report is submitted to an independent auditor (like Deloitte) who verifies primary monitoring data, inspects facilities, and validates the bioinformatics models, ultimately issuing a formal assurance report.

Stage 6: Exchange Publication & Green Loan Procurement

The verified TNFD report is published on major stock exchanges and ESG registries, boosting the corporation’s ratings (e.g., MSCI) and enabling it to secure highly favorable syndicated green loans from institutional investors.
