In Part 1, we examined why uncertainty increases financing costs in nature-based projects and how early, high-quality due diligence reduces the cost of capital. Once risks in nature-based solutions (NbS) are clearly articulated, quantified, and assessed early, they can be priced and structured rather than avoided. This fundamentally changes how investment deals are designed, negotiated, and approved.

In Part II, we explore how rigorous early due diligence reshapes contract structures, strengthens investment committee (IC) decision-making, improves long-term performance, and ultimately supports scalable, lower-cost nature finance.

From Risk Assessment to Better Contract Structures

Early due diligence in nature-based solutions (NbS) enables smarter capital structuring and more flexible contracts. Historically, many fund managers have avoided equity investments in NbS due to perceived jurisdictional, operational, governance, and reputational risks. While these risks are real, they are rarely absolute dealbreakers. The key is converting unknown risks into understood and manageable risks.

Rigorous, NbS-specific due diligence allows investment teams to identify project-level exposure early and design contracts that allocate risk appropriately.

For example:

• Land tenure risk can be addressed with contingency clauses, escrow arrangements, or political risk insurance.

• Uncertain carbon yield projections can be structured with conservative baselines, delivery buffers, or performance-linked pricing.

• Governance risks can be mitigated through milestone-based capital disbursements, oversight boards, audit rights, and step-in provisions.

Offtake agreements for carbon credits illustrate how contract design reduces financing risk. Long-term purchase agreements provide developers with revenue certainty and buyers with secured supply. By allocating volume and delivery risk explicitly, these contracts reduce transaction friction and improve bankability.

In short, early risk clarity enables:

• Flexible contract structures

• Clearer allocation of responsibilities

• Realistic performance benchmarks

• Improved investor pricing and longer tenors

This directly supports a lower cost of capital for well-structured nature-based projects.

Why Fewer Surprises Matter More Than Perfect Outcomes

In complex ecological projects, eliminating all risk is unrealistic. However, minimizing surprises is achievable—and often more valuable than pursuing theoretical perfection.

Projects grounded in thorough due diligence experience fewer post-signing shocks. This is critical because nature-based solutions operate in environments affected by climate variability, policy changes, and implementation challenges.

Carbon credit delivery delays provide a useful example. For corporate buyers pursuing net-zero targets, delayed issuance can disrupt climate commitments, budgeting cycles, and reporting obligations. Rather than relying on optimistic timelines, sophisticated buyers increasingly diversify across multiple projects.

The Structured Finance for Nature Initiative aggregates projects of varying size, geography, and asset type into diversified portfolios. By spreading risk exposure, investors reduce reliance on the performance of any single project, improving portfolio resilience and capital stability.

Contractual safeguards also reduce downside risk. Buyers and investors may negotiate:

• Termination rights

• Performance penalties

• Delivery guarantees

• Insurance coverage

• Volume reallocation rights within portfolios

Ongoing monitoring and verification frameworks help identify issues early, preventing costly renegotiations and protecting realized returns.

Reputational Risk and Governance Due Diligence

Reputational risk is another major driver of capital pricing in nature finance. Corporate buyers prioritize reliability and transparency over overly optimistic projections.

A survey by The Nature Conservancy found that buyers’ top due diligence concerns include social safeguards, governance structures, and developer integrity. Community conflict, overstated impact claims, or weak stakeholder engagement can undermine both ecological and financial outcomes.

As a result, thorough vetting of:

• Project proponents

• Developer track records

• Local partnerships

• Community benefit-sharing structures

has become standard practice in high-integrity nature finance transactions.

By screening for experienced and credible partners, investors reduce the probability of project failure, mismanagement, or reputational damage—factors that directly influence required returns and cost of capital.

What Investment Committees (ICs) Now Expect in Nature Finance

Nature-related risk is now a mainstream financial consideration. Large institutional investors increasingly require detailed, financially grounded assessments of ecological risk exposure.

Norges Bank Investment Management (NBIM), one of the world’s largest asset managers, has explicitly stated that nature risks must be evaluated in financial terms. This includes assessing how exposure to water scarcity, soil degradation, deforestation regulation, or biodiversity loss could translate into higher costs, lower revenues, or asset impairment.

For investment committees, this means:

• Stress-testing financial models against ecological and regulatory scenarios

• Quantifying downside exposure

• Demonstrating mitigation measures

• Linking nature-related risk directly to projected returns

ICs increasingly expect mitigation measures to be embedded in term sheets from the outset. For example, NBIM now requires a no-net-loss-of-nature clause in new renewable energy investments, integrating biodiversity safeguards directly into contractual agreements.

Similarly, carbon offtakers may require delivery guarantees, insurance mechanisms, or performance-linked pricing structures before approving long-term purchase agreements.

The message is clear: early, robust due diligence is no longer optional—it is a prerequisite for institutional capital allocation.

The Emerging Standard in Nature Finance

These developments point toward a new market standard in nature finance: high-quality, data-driven due diligence as the foundation for scaling capital into nature-based solutions.

1. Lower Cost of Capital Through Risk Transparency

Better due diligence reduces uncertainty and improves investor confidence. When a forest restoration or regenerative agriculture project demonstrates:

• Secure land tenure

• Third-party verified baselines

• Realistic growth and yield models

• Strong community agreements

• Transparent governance structures

buyers and lenders are more willing to commit long-term capital, often at more favorable rates.

Reducing ambiguity allows capital to flow where it previously stalled.

2. Alignment of Ecological Integrity and Financial Performance

The best nature finance transactions now explicitly link ecological outcomes with financial resilience.

Palladium’s nature equity team notes that measuring tonnes of carbon reduced, hectares restored, or jobs created also measures risk reduction, resilience, and long-term value creation. Ecological performance is increasingly viewed as a financial risk mitigant rather than a separate objective.

Market standards are reinforcing this shift. The Integrity Council’s Core Carbon Principles and the Taskforce on Nature-related Financial Disclosures (TNFD) framework are raising expectations for transparency, disclosure, and impact integrity. Projects that meet these standards are more likely to attract institutional capital at competitive rates.

3. Standardized, Continuous, and Data-Driven Due Diligence

Due diligence in nature-based solutions is becoming more standardized and dynamic. Investors are using structured frameworks not only for reporting but also to guide pre-investment risk analysis and portfolio monitoring.

Nature finance is moving toward a proactive, resilience-focused model where transactions are structured from the outset to absorb ecological and regulatory shocks. Projects that undergo stringent early diligence and comply with high-integrity standards increasingly benefit from:

• Easier access to capital

• Lower financing costs

• Faster approvals by investment committees

• Reduced renegotiation risk

• Stronger long-term performance

Conclusion: Due Diligence as the Bridge Between Ecology and Capital Markets

A new standard is emerging in nature-based solutions finance. Robust, early-stage due diligence is the mechanism that connects ecological integrity with financial viability.

It allows:

• Risks to be understood and priced

• Contracts to be structured intelligently

• Investment committees to approve deals confidently

• Returns and reputations to be protected

Investors, buyers, insurers, and developers are increasingly aligned in recognizing that credible, high-quality due diligence is not merely best practice—it is essential for scaling nature-based solutions and lowering the cost of capital.
