A $942 billion annual funding gap stands between current conservation investments and what nature actually needs. Foundations deploy billions in grants and PRIs each year—yet most conservation projects lose momentum the moment funding ends.
The math doesn't work. But ensurance changes the equation.
the grant cliff problem
Every foundation program officer knows this pattern: a promising conservation project gets funded, shows strong results during the grant period, then struggles to survive afterward. The "grant cliff" isn't a failure of strategy—it's a structural flaw in how philanthropic capital flows to nature.
Traditional grants create:
- Dependency on renewal cycles
- Competition between grantees for limited funds
- Projects optimized for reporting, not outcomes
- Momentum loss when funding ends
The problem isn't how much foundations give—it's that each dollar only works once.
why leverage ratios matter
At COP16, discussions highlighted the potential to transform $35 billion in current biodiversity financing into $700 billion of conservation funding—a 1:20 leverage ratio. MacArthur's Catalytic Capital Consortium has deployed over $128 million with similar multiplier ambitions. Richard King Mellon Foundation awarded $55 million in 2024 conservation grants and PRIs.
These are meaningful numbers. But most philanthropic capital still deploys at 1:1—one dollar of impact per dollar spent, with no mechanism to recycle or multiply.
| Deployment Model | Leverage Ratio | Durability |
|---|---|---|
| Traditional grant | 1:1 | Ends with grant |
| Standard PRI | 1:3 to 1:5 | Recoverable, but finite |
| Catalytic first-loss | 1:10 to 1:20 | Unlocks private capital |
| Ensurance structure | 1:10+ potential | Self-sustaining if fully subscribed |
ensurance: a two-sided capital structure
Ensurance is a mechanism for proactive protection of natural assets—distinct from insurance, which compensates after damage. For foundations, ensurance offers something grants cannot: a structure that separates who pays from who provides capital, using natural assets as the underlying collateral.
the two sides
Ensurance works because it connects two different types of capital with different needs:
Flow investors (Side A) — These are entities that depend on nature or face nature-related risks:
- Corporates with supply chain or TNFD dependencies
- Insurers and reinsurers seeking risk reduction
- Utilities and municipalities dependent on watersheds
- Public agencies and NGOs with protection mandates
They pay annual ensurance premiums (OPEX, not CAPEX). They're buying risk reduction and continuity of ecosystem services—not assets.
Stock investors (Side B) — These are capital providers seeking yield:
- PRI-aligned real asset investors
- Family offices, endowments, pensions
- Impact funds and conservation finance vehicles
- Infrastructure-style capital
They provide upfront lump-sum capital to acquire or secure natural assets. They receive contracted yield from the premium stream. Their return comes from entry price, premium amount, and contract duration—not from land appreciation. Target financial IRR: 5-12% depending on structure and risk position.
where foundations fit
Foundations are uniquely positioned to play the catalytic role between these two sides:
- First-loss capital — De-risk the investment for stock investors, unlocking multiples of private capital
- Concessionary positions — Accept lower returns to improve the economics for other participants
- Credit enhancement — Guarantee portions of the premium stream to attract institutional capital
- Capacity building — Fund the technical work (valuations, MRV, legal structuring) that makes deals possible
Philanthropic capital doesn't need to fund conservation directly—it can catalyze a self-sustaining system where flow investors fund protection through premiums paid to stock investors.
the ENSURER role
BASIN acts as the ENSURER—the market maker and structurer between both sides. This means:
- Originating natural asset deals
- Pricing ensurance premiums against asset costs
- Structuring contracts with different time horizons (2030, 2040, 2050, or immediate)
- Managing stewardship and MRV
- Executing final ENTRUST transfer when policies complete
Critically, BASIN doesn't need to hold large balance-sheet capital. It arbitrages long-dated premium certainty against upfront capital cost—similar to infrastructure developers or project finance arrangers.
a real example: 83-acre wetland in the southeast
This isn't hypothetical. Here's how the model works for an actual natural asset in our pipeline—an 83-acre wetland and forest in the Southeast Savannas & Riparian Forests bioregion.
the asset
| Metric | Value |
|---|---|
| Size | 83 acres |
| Ecosystems | Inland wetlands, temperate forest |
| Condition | 10/10 (100% intact hydrology, no road access) |
| Annual ecosystem services (Flows) | $1,449,706 |
| Real asset cost (Stocks) | $294,250 |
| Natural cap rate | 493% |
The natural cap rate is the holistic yield—the ratio of annual ecosystem service value to asset cost. At 493%, this wetland generates nearly 5x its purchase price in ecosystem services every year: flood control, water filtration, carbon storage, and habitat that would cost tens of millions to replicate with built infrastructure.
The financial IRR for stock investors is different—5-12% depending on premium structure and time horizon. That's what investors actually receive in cash returns.
ensurance premium options
The asset offers multiple policy structures, each with different premium costs and timelines to permanent protection:
| Policy | Annual Premium | Impact Multiple | Path to ENTRUST |
|---|---|---|---|
| ENSURED | $13,375 | 108x | Year-by-year only |
| ENTRUST 2050 | $29,470 | 49x | Permanent in 2050 |
| ENTRUST 2040 | $35,169 | 41x | Permanent in 2040 |
| ENTRUST 2030 | $70,566 | 21x | Permanent in 2030 |
| ENTRUST T-Zero | $294,250 | 5x | Permanent now |
how the deal could structure
Flow investors: A regional water utility and a downstream municipality pay $35,169/year combined (ENTRUST 2040 policy). They're buying flood risk reduction and water quality protection—services they'd otherwise have to build infrastructure to provide.
Stock investor: A conservation finance fund provides the $294,250 upfront to secure the asset. Their 5-8% IRR comes from the premium stream over 15 years.
Foundation catalytic position: A foundation provides $75,000 in first-loss capital (25% of asset cost) plus a $25,000 MRV grant. This de-risks the deal for the stock investor and funds the verification systems. The foundation achieves 4x leverage on their capital.
Result: By 2040, the wetland enters ENTRUST—permanent protection with title-level restrictions. The foundation's PRI is recovered. The ecosystem is protected in perpetuity.
| Role | Contribution | What They Get |
|---|---|---|
| Flow investors | $35,169/year | Flood protection, water quality, TNFD compliance |
| Stock investor | $294,250 upfront | 5-8% IRR from premium stream |
| Foundation | $75K first-loss + $25K grant | 4x leverage, permanent outcome, recoverable PRI |
| Land | — | Active stewardship, permanent protection by 2040 |
why this works financially
The ensurance model solves a structural mismatch:
- Flow investors cannot deploy CAPEX for land acquisition, but they can pay OPEX for risk reduction
- Stock investors want yield (5-12% IRR), not operational exposure to land management
- Nature assets are long-lived, low-volatility, and underpriced relative to the risk reduction they provide
Ensurance converts diffuse ecosystem value into bankable cash flows, and stewardship costs into investable yield.
This is not carbon markets, offsets, donations, or speculative tokens. It's nature-backed infrastructure finance—a risk-pricing mechanism with ecological collateral.
what this isn't
To be clear about what ensurance is and isn't:
| What people assume | What it actually is |
|---|---|
| A new grant mechanism | A capital structure with payors and investors |
| Guaranteed returns | Returns contingent on premium subscription |
| Works for any land | Requires flow investors willing to pay premiums |
| Instant liquidity | Long-duration, infrastructure-style capital |
| Replacing conservation finance | Complementing existing tools with new structure |
Ensurance works when there are identifiable parties who benefit from ecosystem services and are willing to pay for their continuation. Not every natural asset has this—but many do.
what foundations can do now
1. identify premium payors in your portfolio
Which entities depend on the ecosystems your grantees protect? Utilities, municipalities, corporates, insurers? These are potential flow investors whose premiums could fund protection.
2. structure catalytic PRIs for leverage
Rather than deploying PRIs as slightly-concessionary loans, structure them as first-loss positions that unlock multiples of private capital through ensurance structures.
3. fund deal origination
The bottleneck is often technical work: valuations, legal structuring, MRV systems, premium negotiations. Grants for this infrastructure create leverage beyond the grant itself.
4. pilot ENTRUST for legacy protection
For landscapes the foundation cares about permanently, ENTRUST structures create self-sustaining protection without ongoing grant dependency—if the premium stream is secured.
frequently asked questions
how is this different from traditional conservation PRIs?
Traditional PRIs are typically loans that get repaid—the capital cycles, but impact ends. Ensurance PRIs catalyze a structure where flow investors pay premiums that fund both investor yield and ongoing protection. The catalytic capital is recoverable, and the protection continues.
what if flow investors don't materialize?
This is the key risk. Ensurance only works when there are parties willing to pay premiums for risk reduction or ecosystem service continuation. Without flow investors, the structure doesn't close. This is why deal origination and premium sourcing are critical—and why philanthropic grants for this work create leverage.
what's the difference between natural cap rate and financial IRR?
Natural cap rate (e.g., 493%) is the holistic yield—annual ecosystem service value divided by asset cost. It measures what nature provides relative to what the asset costs.
Financial IRR (5-12%) is what stock investors actually receive in cash returns from the premium stream. The gap between these numbers represents value that flows to ecosystem protection, stewardship, and the broader protocol—not extracted as investor profit.
what's the risk profile for foundations?
First-loss positions carry higher risk than senior debt. If premiums underperform or flow investors default, the foundation's position absorbs losses first. The upside is leverage ratios and durability that grants cannot achieve—but it's not risk-free.
can existing grantees participate?
Yes. Foundations can provide technical assistance to help land trusts and conservation organizations identify premium payors and structure ensurance deals. This transitions grantees from grant dependency to earned revenue.
the opportunity window
The $942 billion conservation funding gap won't close through grants alone. Private capital is available—it needs de-risking and structure. Entities that depend on nature are willing to pay for its continuation—they need mechanisms to do so.
Foundations that move first will:
- Achieve higher leverage on existing budgets
- Create durable outcomes rather than project cycles
- Demonstrate measurable impact to boards
- Pioneer mechanisms that scale across the sector
Ensurance doesn't replace philanthropic capital—it gives it a multiplier. The question is whether foundations will catalyze these structures or leave the gap to close itself.
