For centuries, financial markets have been remarkably good at valuing what can be extracted: timber, crops, minerals, oil and so on. But they have struggled to value what must be protected: standing forests, clean rivers, watersheds and ecosystems.

This imbalance sits at the heart of today’s biodiversity and climate crises. Nature underpins our economies, providing food, water, climate regulation, pollination and more. Yet much of its value remains invisible in financial systems, and markets still reward depletion more consistently than regeneration. Indeed, the recent UNEP State of Finance for Nature report found that for every $1 the world invests in nature, it invests $30 in destroying it.

To protect the natural world we all rely on, we need to flip this equation on its head. But this means solving a challenge the world has long struggled to crack: Can the capital markets which have driven extraction and degradation be redesigned to reward conservation and stewardship instead?

A growing group of innovators believes the answer is yes. One emerging model, the Natural Asset Company (NAC), aims to do precisely that.

What Is a Natural Asset Company?

A Natural Asset Company or NAC (pronounced “nack”) is a new type of corporation, developed by the Intrinsic Exchange Group (IEG), that’s designed to turn healthy ecosystems into investable assets. Instead of generating profits through resource extraction, NACs are structured so that their long-term value depends on protecting and enhancing natural systems — such as forests, wetlands or grasslands — and the services they provide. Investors buy equity not in a mine or a plantation, but in the stewardship of the living systems that underpin our societies and economies.

Operationally, NACs would hold the economic rights to natural services, such as clean water and healthy soils, generated by a specific ecosystem. They would assign monetary value to these ecosystem services based on the economic benefits they provide and work in collaboration with existing land stewards (Indigenous groups, businesses, conservation organizations or others) to support conservation, restoration and sustainable management.

Ecosystem services are thus treated as the productive assets of the company: As the ecosystem is protected or restored, the quantity and quality of services it generates increases, raising the underlying asset value of the NAC and therefore the value of the company’s equity. NACs may also generate revenue streams in the form of ecological credits, sustainable harvesting, ecotourism, or other payments for ecosystem stewardship. This combination under a familiar corporate structure creates an opportunity whereby shareholders and investors can realize financial returns from keeping ecosystems healthy.

The first NAC structures have already been developed, focused on ecosystem services generated by Indigenous lands in Alaska and on large scale working landscapes in Montana. But a few demonstrations does not (yet) make an asset class. To scale, NACs must move from bespoke innovation to standardized architecture.

What Makes Natural Asset Companies Different?

Conservation finance has struggled to align capital markets with ecosystem preservation for decades. NACs represent one of the first attempts to structurally shift this dynamic. They seek to align finance with conservation and restoration rather than just conversion and extraction. They also aim to recognize the full suite of ecosystem services that healthy landscapes provide, rather than monetizing only a narrow subset (such as via carbon, water or biodiversity credits).

If successful, NACs could represent a breakthrough — shifting nature from being an externality or offset into a core appreciating asset within capital markets.

NACs represent a departure from past conservation finance efforts in a few key ways:

From projects to architecture 

Most conservation finance today is project based, delivered through grants, carbon credits or bespoke blended finance structures. NACs, by contrast, seek to embed ecosystems directly into equity markets. Instead of financing discrete interventions, they create enduring corporate structures whose value is tied to the long-term health of natural systems. In this manner, a NAC may act as an umbrella structure that incorporates any number of existing conservation activities and ecosystem service revenue streams within a single equity vehicle. Nature functions much like equity capital: When protected and allowed to regenerate, it appreciates over time as ecosystem services strengthen and compound, thereby providing long term financial appreciation and gains.

From voluntary ESG to fiduciary duty 

Fiduciary duty is the legal obligation of corporate directors and officers to act in the best interests of the corporation and its shareholders. This duty has at times been focused on short-term rather than long-term interests, and traditional environmental, social and governance (ESG) frameworks have largely been voluntary and often peripheral to core financial performance. NACs would tie fiduciary responsibility directly to ecosystem performance. As ecosystems are protected and regenerate, the NAC’s value increases. If ecosystems degrade, so does the NAC’s value. So ecological performance becomes financially material.

From reporting harm to monetizing stewardship 

Corporate sustainability reporting has historically focused on reducing negative impacts. NACs aim to make positive ecological performance the source of financial appreciation. Since capital markets allocate trillions of dollars each year, even a small reallocation toward asset structures built on stewardship rather than extraction could have transformative implications for nature. According to the UNEP State of Finance for Nature report, an additional $700 billion per year (less than 1% of global GDP) is needed globally to halt and reverse biodiversity loss.

The Promise and Challenge of Expanding NACs

NACs have serious potential. Treating nature as an asset could enable companies to protect landscapes in perpetuity — not as philanthropy, but as a core component of their brand and value proposition. Investors searching for long-term, real-economy assets could gain exposure to a new category of value. Philanthropists, in turn, could catalyze early structures that safeguard ecosystems, generate returns, and are built for long term sustainability rather than short term protection.

NACs are still in their infancy and must overcome significant hurdles before becoming mainstream. But history shows us this is possible. Asset classes such as infrastructure companies (which enabled capital markets to finance long-term assets like utilities, power grids, toll roads, airports and ports) and REITs (which allowed investors to gain exposure to diversified property portfolios through standardized, publicly traded vehicles) were built through market rules and regulatory frameworks. NACs may follow a similar path, representing an effort to construct financial architecture around natural systems.

Specifically, this will require:

Awareness and understanding

Natural Asset Companies are an unfamiliar concept to most investors, regulators and companies. As with any new asset class, greater awareness and support, alongside credible early adopters, are critical. Fortunately, awareness of this opportunity has dramatically risen over the last year or so, and there is now an ecosystem of actors working to better advance the work on nature as an asset class.

A need for pioneers

Early-stage innovation requires patient capital and investors willing to depart from convention. The decisions of a small number of early investors could define the trajectory of this market. The appeal may lie not only in growth potential, but also in reducing the very real financial and material risks tied to the loss of ecosystem services. We expect the coming 12-24 months could very well reveal the investors and landscapes that will serve as the foundation for this new asset class in the future.

Standardization and safeguards

Without clear rules and standards, NACs risk being dismissed as speculative, or worse, misused. To move from prototype to scalable model, four foundational building blocks are essential:

  1. Valuation and accounting frameworks that align with recognized standards, such as the UN’s System of Environmental-Economic Accounting (SEEA), so that ecosystem values are measured consistently and transparently. The Natural Asset Accounting Standards Board (NAASB) at Fordham University’s Responsible Business Center is beginning to develop frameworks to advance this work.
  2. Independent assurance mechanisms to verify ecological claims and guard against greenwashing. IEG has engaged several accounting firms to provide an assurance opinion on NACs’ ecological reporting.
  3. Legal frameworks that clarify rights to ecosystem services while protecting Indigenous and community interests.
  4. Listing and market structures that allow NACs to access capital markets under clear, replicable rules.

Designing and advancing these elements will require progress and collaboration across many public and private actors and stakeholders. Done right, this could help NACs transition from niche pilots to investable, mainstream instruments.

NACs in a Broader Financial Evolution

Natural Asset Companies are among the most advanced models in the innovative nature finance field that would place a direct economic value on nature. But they are not emerging in isolation. They sit within a broader movement responding to the need to better align financial systems with ecological systems.

Some companies are exploring ways to put nature on the balance sheet, integrating ecosystem value directly into financial reporting in a manner that could realize increased economic valuation and returns.

Others are experimenting with new governance models; for example, Patagonia’s ownership transfer to the Patagonia Purpose Trust and Holdfast Collective separates voting control from economic ownership to lock in long-term environmental outcomes. Meanwhile, some innovators are exploring digital “natcoins,” tokenized ecosystem credits and decentralized finance platforms (including blockchain) aimed at lowering transaction costs and expanding transparent, programmable capital flows to nature-based value streams.

These innovations suggest a common recognition: Markets are beginning to acknowledge that ecosystems are not externalities, but foundational assets. The question is not whether nature has value. It always has. The question is whether our financial systems can reflect that economic value creation must account for the ecological systems that underpin it.

Investing Early in Nature as an Asset Class

For centuries, paintings and sculptures were objects of personal devotion or patronage. Over time, they evolved into recognized stores of value — catalogued, appraised, securitized and traded through formal auction markets. Today, blue-chip art is treated as an alternative asset class, held in institutional portfolios and family offices alongside real estate and infrastructure. This shift did not change the intrinsic beauty of the art. It changed the financial architecture around it.

The world’s intact forests, wetlands and coral reefs are, in a very real sense, masterpieces of natural capital — repositories of beauty, biodiversity and ecological function. These natural landscapes and ecosystems have always generated economic benefits by filtering water, regulating the climate and sustaining food systems. What they have lacked is recognized financial structure. Moreover, as ecosystems degrade, risks to supply chains, insurance markets and government stability increase. Aligning markets with the natural systems that underpin them is not just good for nature and economic growth, but also helps minimize these growing risks.

Asset classes are not born but built, constructed through standards, disclosure regimes and governance frameworks. The question is whether markets can evolve to treat natural landscapes and seascapes not merely as scenery or resources to be liquidated, but as the appreciating real assets they truly are. Natural Asset Companies represent one early attempt to build that architecture.
