Unlocking Long-Term Budgets for Nature: A Practical Framework for Sustainability Leaders

How do you secure long-term corporate budgets for nature? To secure long-term budgets for nature, sustainability leaders must transition from pilot projects to financially credible business cases. This is achieved by identifying specific nature dependencies, quantifying physical and transition risks in financial terms, and integrating nature-based solutions directly into existing enterprise risk management and climate strategies.

What is the five-step framework for unlocking nature budgets?

The five-step framework for unlocking nature-positive investment involves:

1. Identifying dependencies on ecosystem services;
2. Quantifying risks and opportunities financially;
3. Scoping targeted initiatives with clear ROI;
4. Linking nature to climate goals;
5. Securing cross-functional buy-in from Finance and Risk teams.

Step 1: Identify Your Specific Dependencies and Impacts on Nature

Nature dependencies are the specific ecosystem services—such as water, soil health, and pollination—that a business requires to function. To build a budget case, sustainability teams must move beyond general commitments and map where these services are directly connected to operational performance.

Key areas to evaluate include:

• Ecosystem Services: Water availability, flood protection, and soil fertility.
• Resource Extraction: Impacts from land use and raw material sourcing.
• Supply Chain Exposure: Identifying "hidden" dependencies in upstream tiers.

Step 2: Assess and Quantify Risks and Opportunities in Financial Terms

Nature-related risks must be quantified using likelihood and magnitude metrics to be included in capital allocation processes. When risks like water scarcity or regulatory change (transition risk) are translated into potential costs or revenue loss, they become actionable for the CFO.

This may involve estimating potential effects on operating costs, input prices, revenue continuity, or asset values.

Scenario analysis can be particularly useful for medium- and long-term risks. For example:

• What would sustained soil degradation mean for raw material costs over five to ten years?
• How would tightening regulation affect sourcing practices?
• How resilient are key sites to water stress or extreme weather?

This analysis often reveals opportunity alongside risk — including efficiency gains, supply chain stability, access to premium markets, and enhanced long-term resilience.

Once you have prioritised which risks are most relevant to your organisation, the next step is to think about risk mitigation.

Step 3: Scope Initial Nature Initiatives with Clear ROI

Targeted nature initiatives should address the specific material exposures identified in the previous steps. Rather than a broad list of "green" projects, focus on a portfolio that offers a measurable Return on Investment (ROI) through cost savings or risk reduction.

Effective initiatives often include:

• Regenerative Agriculture: Improving soil health to stabilize raw material costs.
• Sustainable Sourcing: Reducing exposure to deforestation-linked supply chain shocks.
• Ecosystem Restoration: Utilising nature-based solutions for flood or drought resilience.

Step 4: Link Nature to Climate and Strategic Business Goals

Nature-based solutions are often more successful when integrated into existing corporate priorities like Net Zero or supply chain resilience. By framing nature as a tool to achieve climate targets, sustainability leaders can access existing climate budgets rather than requesting separate funding.

• Carbon Sequestration & Biodiversity: Restoration projects do more than protect species; they serve as critical carbon sinks that support climate mitigation targets.
• Operational Resilience: Natural buffers, such as restored wetlands, act as a climate adaptation strategy to protect physical assets from extreme weather.
• Unified Reporting: Aligning nature data with frameworks like CSRD or TNFD ensures that your climate and nature disclosures reinforce one another, reducing the total reporting burden.

Step 5: Secure Cross-Functional Buy-In to Institutionalise Investment

Internal buy-in requires engaging with Finance, Risk, and Procurement teams early in the process. Investment becomes long-term only when it is embedded in the company’s enterprise risk management (ERM) and annual planning cycles.

To ensure sustained investment:

1. Executive Sponsorship: Identify a C-suite champion.
2. Cross-functional Ownership: Assign KPIs to procurement and operational leads.
3. Governance Integration: Include nature risks in standard board-level reporting.

Moving from Pilots to Enterprise-Level Investment

As regulatory pressure from frameworks like CSRD and TNFD increases, nature-related risk is becoming a mainstream financial concern. By following this five-step framework—mapping dependencies, quantifying risk, scoping ROI, linking to climate, and securing buy-in—sustainability leaders can transform nature from a "nice-to-have" into a core strategic investment.
