Natural Asset Companies (NACs), Global Dashboard (2025)

Natural Asset Companies (NACs) are a new class of publicly traded companies, developed by the NYSE and Intrinsic Exchange Group (IEG), that manage and monetize the productivity and health of natural assets-such as forests, wetlands, and marine areas-by assigning value to the ecosystem services they provide (e.g., carbon sequestration, biodiversity, clean water). NACs are designed to unlock investment for conservation and sustainable management at scale.

The NYSE and IEG are developing unique listing standards for NACs, including ecological performance reporting frameworks independently attested by PCAOB-registered firms^[8].
The Government of Costa Rica, with IEG and the Inter-American Development Bank, is preparing the first sovereign NAC pilot focused on forest and ecosystem preservation^[6].
Private sector NACs are in development, with further announcements expected in 2025^[6].
IEG’s accounting framework measures ecological performance alongside financial data, enabling transparent valuation of ecosystem services^[6][8].

NACs represent a structural innovation in sustainable finance, offering a mechanism for investors to directly support conservation and restoration at scale, while providing transparent, independently verified reporting on both financial and ecological outcomes. This approach aims to bridge the gap between capital markets and nature, supporting the goals of the Kunming-Montreal Global Biodiversity Framework.

Natural Asset Companies (NACs) Dashboard

Natural Asset Companies (NACs) are a new asset class, developed by the NYSE and Intrinsic Exchange Group, that seek to bridge this gap by enabling the direct listing and trading of companies whose core purpose is to manage, restore, and grow the value of natural assets and the ecosystem services they produce. NACs are structured to ensure that proceeds from their IPOs and ongoing operations are invested in conservation and sustainable management, with robust governance and independent measurement of ecological outcomes. Early pilots, such as those in Costa Rica, are underway with support from multilateral development banks and private investors.

$125 trillion: The estimated annual global value of ecosystem services provided by nature, such as climate regulation, water purification, carbon sequestration, and pollination. This figure, cited by the NYSE and Intrinsic Exchange Group, underscores the foundational role that natural capital plays in supporting the global economy and human well-being. It is a theoretical aggregate: a measure of what nature contributes to society each year, whether or not those services are monetized in markets.
€125 billion: The total assets under management (AUM) by the world’s top 40 natural capital investment managers as of 2025. This figure captures the actual capital currently invested in funds and companies focused on natural assets and ecosystem services. While this sum is growing rapidly, it remains a tiny fraction of the total value that nature provides.

The similarity in the numbers is coincidental; the difference in scale is vast-one is in trillions, the other in billions, and the units are not directly comparable. The charts are designed to highlight both the potential (the value of ecosystem services) and the current reality (the scale of nature-focused investment).
