Biodiversity as Balance Sheet: Nature Risks in the ESG Era

For the past decade, the environmental dimension of ESG has been dominated by climate change, carbon emissions, transition risks, and net-zero pathways. Yet a growing body of evidence suggests that climate is only one piece of a much broader puzzle.

Nature-related risks encompassing biodiversity loss, ecosystem degradation, and resource scarcity are fast emerging as a material concern for businesses and investors alike. A 2023 PwC study highlights that over 50% of global GDP is moderately or highly dependent on nature, representing more than $58 trillion of economic value creation. In other words, the erosion of ecosystems is not a peripheral environmental issue: it is a direct financial risk.

🐝 Expanding the “E” in ESG

The concept of natural capital is reframing how businesses understand the “E” in ESG. Ecosystem services such as pollination, soil fertility, freshwater availability, and carbon sequestration underpin the resilience of entire industries:

• Agriculture depends on healthy soils and pollinator populations. The World Economic Forum estimates that 75% of global crops rely on pollinators.

• Consumer goods rely on deforestation-free supply chains for raw materials.

• Technology and manufacturing face heightened exposure to water stress, with implications for semiconductor and textile production.

These dependencies demonstrate that biodiversity loss and resource scarcity are not distant sustainability challenges but systemic financial risks.

📊 The Regulatory & Reporting Shift

Regulatory momentum is catching up. In September 2023, the Taskforce on Nature-related Financial Disclosures (TNFD) released its final recommendations, providing a framework for companies to assess, disclose, and manage nature-related dependencies and impacts.

Policymakers are already integrating these principles into mandatory disclosure regimes. The EU’s Corporate Sustainability Reporting Directive (CSRD) explicitly requires biodiversity and ecosystem disclosures, while the UK’s forthcoming Sustainability Disclosure Standards (SDS) are expected to align closely with both the TNFD and ISSB standards.

This signals a decisive shift: ESG reporting is evolving from a climate-centric exercise to one that embeds nature and biodiversity at its core.

💰 Why Investors Are Paying Attention

For investors, nature-related risks are becoming an essential component of portfolio analysis. Exposure to ecosystem decline can manifest as:

• Operational risk: Reduced yields or rising costs from degraded soils and water scarcity.

• Regulatory risk: Stricter biodiversity protection laws affecting supply chains.

• Reputational risk: Stakeholder backlash against unsustainable land-use practices.

Institutional investors are beginning to incorporate biodiversity screens into investment decision-making. Meanwhile, financial institutions are mapping portfolio exposure to ecosystem services, and sustainable finance instruments (from green bonds to sustainability-linked loans) are increasingly embedding biodiversity-related performance targets.

The implication is clear: nature risk is financial risk.

🌍 Strategic Imperatives for Companies

Companies that proactively address nature-related risks will be better positioned to attract capital, secure resilience, and sustain long-term value creation. Leading practices include:

• Dependency mapping: Systematically identifying where operations and suppliers rely on natural capital.

• Target setting: Establishing science-based goals for biodiversity protection, water use, and land restoration.

• Framework alignment: Preparing disclosures in line with TNFD, CSRD, and SDS requirements.

• Collaborative engagement: Partnering with NGOs, regulators, and industry peers to scale nature-positive strategies.

This approach shifts ESG from a compliance exercise to a driver of strategic innovation and risk management.

✨ Why This Matters

Nature loss is not a future concern, it is a present financial risk with systemic implications. The Green Finance Institute and WWF recently warned that nature degradation could shrink the UK’s GDP by 5% within the decade if the private sector fails to act.

Companies that integrate biodiversity and ecosystem considerations into their ESG strategies will not only meet evolving disclosure requirements but also strengthen resilience, investor confidence, and long-term competitiveness.

As PwC’s findings underscore, safeguarding nature is not philanthropy. It is a business and economic imperative.
