IPBES makes it clear: biodiversity loss is a financial risk

For institutional investors, the most important message from the new IPBES Business and Biodiversity Assessment is this: Biodiversity loss is not an environmental side issue. It is a system-level economic risk embedded across portfolios.

The assessment makes three points that are directly relevant to investors:

1. Long-term economic productivity — and therefore portfolio returns — depends on functioning ecosystems
2. Current capital allocation patterns are contributing to ecological decline rather than stabilising it
3. Financial markets are not yet consistently reflecting biodiversity-related physical and transition risks in asset prices
   

Taken together, this suggests a growing mismatch between ecological reality and financial valuation.

The economy depends on nature — and that creates systemic risk

IPBES is explicit that all businesses depend, directly or indirectly, on biodiversity and nature.

These include material inputs such as raw materials and energy, regulating functions such as water flows, soil fertility and climate stability, and non-material contributions such as cultural and social value.

These dependencies are often invisible because they are embedded several layers down the value chain. For example:

• A retailer may not manage farmland directly, but its profitability ultimately rests on soil health, water availability and stable growing conditions
• Construction and infrastructure projects depend on reliable water systems, land stability and extractive supply chains
• Even technology companies — frequently viewed as detached from the natural world — rely on vast quantities of water, land and energy to power data centres and digital infrastructure

When those ecological systems come under strain, the financial exposure may surface far from the original source of impact.

When biodiversity declines, these systems become far less stable.

That instability can manifest as:

• Reduced agricultural productivity
• Water scarcity and higher operating costs
• Increased flood or wildfire exposure
• Disruption to supply chains
• Greater volatility in commodity markets
  

IPBES characterises biodiversity decline as a systemic risk to the economy and financial stability, noting that biodiversity loss, climate change and pollution are deeply interconnected and can amplify one another.

For diversified investors, that framing matters.

Systemic risks do not remain contained within one sector. They transmit through markets, geographies and asset classes.

If ecosystem degradation undermines economic productivity at scale, long-term return assumptions may be affected across portfolios — not just in “nature-heavy” industries.

Capital allocation is reinforcing the problem

The assessment highlights a stark imbalance in global financial flows.

In 2023, approximately $7.3 trillion in public and private finance flowed to activities with direct negative impacts on nature, including environmentally harmful public subsidies and private investment in high-impact sectors.

In comparison around $220 billion flowed to activities supporting conservation and sustainable use.

Private finance accounts for the majority of harmful flows.

For investors, this is not simply a moral observation. It raises two financial questions.

First: are portfolios materially exposed to activities that inadvertently depend on continued ecosystem degradation?

Second: what happens when policy reform, subsidy removal or regulatory tightening reprices those activities?

If governments act to remove environmentally harmful subsidies or strengthen biodiversity regulation — as many have committed to do under the Global Biodiversity Framework — capital could face transition risk similar to that seen in carbon-intensive sectors.

In other words, the current capital allocation pattern may embed future repricing risk.

Businesses can act now

Crucially, the assessment makes clear that businesses do not need to wait for new science or perfect data. All businesses depend on and impact biodiversity — and they can act now based on existing knowledge.

The report also reframes business not only as a driver of biodiversity loss, but as a potential agent of positive change.

Information about impacts and dependencies is not abstract. It can guide reporting, strengthen transparency and inform strategic decision-making. That is particularly true where companies draw on the full range of available knowledge, including place-based expertise held by Indigenous Peoples and local communities who steward many of the ecosystems on which business depends.

These factors can improve outcomes for both biodiversity and long-term business performance.

In practical terms, action is possible across multiple levels of decision-making:

• At the corporate level, companies can integrate biodiversity into strategy and financial planning, set targets, strengthen governance and embed oversight at board level
• At the operational level, businesses can establish baselines, monitor impacts and move beyond mitigation towards restoration and sustainable management
• Across value chains, companies can improve traceability, set supplier standards and address embedded impacts and dependencies upstream and downstream
• At the portfolio level, financial institutions can assess biodiversity exposure, engage investee companies, shift capital away from harmful activities and align financing with improved outcomes
  

These actions are not theoretical. The frameworks, tools and governance approaches already exist.

What this means in practice

The IPBES assessment does not prescribe specific investment strategies. But it sharpens several questions for institutional investors:

• Are biodiversity-related physical and transition risks integrated into scenario analysis?
• Are portfolios exposed to sectors reliant on harmful subsidies or fragile ecosystems?
• Do business, governance and corporate strategies address their impacts and dependencies on nature?
• Are climate transition plans also assessed against ecological constraints, including land and water limits?
  

The regulatory direction of travel is towards greater transparency, stronger incentives and more explicit risk recognition. Biodiversity loss now a structural constraint on growth. For investors, the issue is no longer awareness. It is alignment — between ecological reality and capital allocation.
