IFC’s Biodiversity Finance Metrics Framework: Navigating New Terrain for Financial Institutions

The International Finance Corporation’s recent publication of its Biodiversity Finance Metrics for Impact Reporting supplement marks a pivotal moment on nature for the financial services sector. This framework addresses the mounting demand for comprehensive guidance on biodiversity impact reporting. As biodiversity deteriorates at unprecedented rates and the Kunming-Montreal Global Biodiversity Framework calls for a whole-of-economy transformation to halt biodiversity loss by 2030, financial institutions find themselves at the epicentre of this transformation.

The supplement builds upon IFC’s Biodiversity Finance Reference Guide, providing structured metrics for measuring impacts across three main investment categories—activities generating biodiversity co-benefits, investments in biodiversity conservation and restoration, and nature-based solutions. The framework includes specific metrics such as reduction in synthetic fertiliser use by at least 20% (measured in kg/ha and percentage terms), increase in species richness and relative abundance (measured numerically), and improvements in site-specific soil quality indicators including nutrient concentration, pH level, and soil organic matter. These metrics must be established against baseline measurements using internationally recognised benchmarks, creating significant methodological complexity. This development presents both unprecedented opportunities for financial institutions to lead in nature-smart financing and significant challenges in integrating complex biodiversity considerations into established risk management frameworks.

Financial institution actors most affected and skills requirements

• Banks face the most immediate impact across their credit risk management, sustainable finance, and environmental and social governance (ESG) departments. Research indicates that 36% of financial sector exposures are to firms with high or very high dependency on at least one ecosystem service, whilst studies demonstrate the complexity of assessing largely indirect biodiversity impacts across global portfolios. Credit and risk management teams must develop sophisticated understanding of nature-related physical and transition risks, requiring new skills in ecological risk assessment, understanding ecosystem service dependencies, and evaluating long-term viability of businesses in biodiversity-sensitive sectors. ESG and sustainable finance departments need comprehensive expertise in biodiversity footprinting tools, baseline measurement establishment, and implementing tiered approaches to screen portfolio impact using geospatial biodiversity data.
• Insurance companies must enhance their underwriting and investment capabilities to integrate biodiversity considerations. Actuarial departments require new competencies in assessing how ecosystem service degradation affects insurance risks, particularly in agriculture, water resources, and catastrophic event modelling. Investment teams need skills in evaluating nature-based solutions financing structures and understanding the financial implications of ecosystem service valuation methodologies, which can involve complex calculations of avoided costs, replacement costs, and contingent valuation.
• Asset managers and institutional investors must develop enhanced due diligence capabilities across their portfolio management, research, and ESG functions. Teams require expertise in identifying “impact hotspots” where priority portfolios intersect with priority locations for biodiversity risk, implementing TNFD’s LEAP approach (Locate, Evaluate, Assess, Prepare), and understanding the complexities of monetary valuation approaches for ecosystem services which involve multiple methodologies and significant data limitations.
• Development finance institutions (DFIs) need to strengthen their project evaluation and monitoring capabilities. Environmental and social specialists must master the IFC’s three-tiered biodiversity finance categories and develop expertise in nature-based solutions cost-benefit analysis, which involves assessing multiple stakeholders and beneficiaries across different temporal scales. Programme teams require skills in designing blended finance structures for biodiversity projects, understanding that successful financing often requires combining different funding sources rather than relying on single instruments.
• Regulators and central banks must build new supervisory capabilities to assess biodiversity-related financial risks. Risk assessment teams need to understand frameworks such as the ecosystem service degradation sensitivity indicator (EDSI) to quantify how damages to ecosystem services can impact banks’ resilience through increasing credit risk-related losses. Policy development functions require expertise in designing biodiversity finance taxonomies and understanding the interconnected nature of climate and biodiversity risks.

Risk and urgency: Consequences of inaction for financial institutions

Financial institutions that fail to address biodiversity-related skills gaps face cascading operational and strategic consequences that threaten their competitive positioning and long-term viability. Reliable data and assessment processes for biodiversity risks remain severely lacking, with institutions struggling to identify meaningful metrics comparable to CO₂ emissions for climate risk. This data scarcity creates operational difficulties, as institutions cannot accurately price biodiversity-related risks in their lending and investment decisions, leading to potential mispricing of credit risk and inappropriate portfolio allocations.

The complexity of biodiversity impact assessment compounds these challenges significantly. Unlike climate risks with established measurement frameworks, biodiversity risks involve a large number of variables, the lack of meaningful data and the novelty of the topic, creating difficulties for institutions in making the complex issue manageable within existing risk management systems. Financial institutions face particular challenges in capturing largely indirect, complex, and global biodiversity impacts across their portfolios, with dependencies spanning multiple ecosystem services and geographic locations that are difficult to monitor and quantify.

Business model disruption represents a critical long-term risk as institutions unprepared for biodiversity integration struggle to adapt to evolving market expectations and regulatory requirements. Without adequate biodiversity assessment capabilities, institutions cannot credibly deliver on sustainability commitments, exposing them to increased stakeholder pressures and potential reputational damage.

How WeESG can support financial institutions

WeESG’s comprehensive training programmes directly address the critical skills gaps identified in biodiversity finance implementation, offering targeted capability building across key competency areas that financial institutions require for effective risk management and opportunity identification.

• Nature-related risk assessment for FIs equips teams with practical skills in implementing TNFD’s LEAP methodology at a counterparty/client and portfolio level, understanding ecosystem service dependencies, and developing tiered approaches to biodiversity impact screening across portfolios. This includes hands-on training in establishing baseline measurements and applying internationally recognised benchmarks for biodiversity metrics.
• Biodiversity finance structuring and measurement provide expertise in developing and implementing biodiversity finance framework, covering activities generating biodiversity co-benefits, conservation and restoration investments, and nature-based solutions financing. Training includes practical application of both simple and complex metrics, with emphasis on overcoming the methodological challenges to support the structuring of impactful financial products.
• Biodiversity reporting focus on building confidence in mapping biodiversity metrics to TNFD disclosure requirements and Global Biodiversity Framework targets, addressing the critical gap between impact measurement and regulatory compliance. The programme emphasizes double materiality, looking at metrics and data that monitor and communicate on financial risk biodiversity loss as well as the impact of a financial product and portfolio on biodiversity.
