Nature and biodiversity finance: who funds conservation, restoration and nature-positive business
147 matching capital sources on the AESFIP database · Last checked November 2026
Nature finance pays for protecting, restoring and sustainably using ecosystems: forests, wetlands, grasslands, mangroves, coral reefs and the species that depend on them. It also backs businesses whose revenue depends on healthy land and water, such as sustainable forestry, agroforestry, regenerative agriculture and community conservancies.
This guide is for project developers, conservation organisations, landholders and nature-positive companies in developing countries, and for the advisors and investors who work with them. It separates funders that accept proposals or invest directly from those that only work through governments, and lists the organisations on our database with a nature or biodiversity mandate. Africa has the deepest coverage on our database.

How big is the biodiversity finance gap?
Under the Kunming-Montreal Global Biodiversity Framework, adopted in 2022, governments agreed to mobilise at least $200 billion a year for biodiversity from all sources by 2030, including international flows to developing countries of at least $20 billion a year by 2025 and $30 billion by 2030.
For project developers, the practical point is that most of this money will still arrive through public programmes, conservation trust funds and blended funds — not as open calls from private investors. Knowing which channel a funder uses saves months.
The main types of nature finance
Each source suits a different kind of project and revenue model:
- Conservation and restoration grants from global funds, bilateral donors and foundations — for protected areas, community conservation and early-stage restoration.
- Conservation trust funds — national or regional endowments, often capitalised by donors or debt-for-nature swaps, that issue grants to local organisations every year.
- Results-based payments for reduced deforestation, usually agreed with national or sub-national governments rather than individual projects.
- Blended investment funds that lend to or invest in sustainable forestry, agroforestry and deforestation-free supply chains, often with a first-loss layer from donors.
- Nature-based carbon credits sold to corporate buyers and intermediaries, sometimes with upfront pre-finance.
- Biodiversity credits — an early market with few committed buyers, best treated as additional upside.
Funders that work directly with projects and companies
Several nature funders on our database accept proposals or invest in companies directly. The GEF Small Grants Programme funds community and civil-society organisations through national coordinators. Investment funds such as the &Green Fund, the eco.business Fund, Mirova's nature strategies and Conservation International Ventures finance businesses whose models reduce deforestation or restore land, each with its own geographic and ticket-size limits.
National conservation trust funds — for example BIOFUND in Mozambique and the Foundation for Protected Areas and Biodiversity of Madagascar — run regular grant cycles for local organisations. These are often the most reachable source for smaller projects.
Funders that work through governments or partners
The Global Environment Facility and its Global Biodiversity Framework Fund, the Forest Carbon Partnership Facility, the Central African Forest Initiative and most bilateral forest programmes fund national programmes. Projects reach this money through a government focal point, an implementing agency or a partner organisation that holds the grant.
If your project fits one of these programmes, the route in is to identify the agency running the national programme and position your project as a delivery partner, not to apply to the fund itself.
What makes a nature project fundable
Screening teams look for the same building blocks:
- Secure land or resource rights, or a formal agreement with the community or government that holds them.
- Measurable outcomes — hectares protected or restored, species indicators, or verified emission reductions.
- A long-term financing plan that does not depend on a single grant.
- Community consent and benefit-sharing that is documented, not assumed.
- For investment funds: a revenue model, such as timber, crops, tourism fees or carbon credits, that can repay capital.

- Global Biodiversity Framework Fund (GBFF)Climate FundThe Global Biodiversity Framework Fund (GBFF) was established by the GEF at the request of parties to the Convention on Biological Diversity’s COP15 to support implementation of the Kunming-Montreal Global Biodiversity Framework. Launched at the Seventh GEF Assembly in 2023, the fund aims to help countries strengthen national-level biodiversity management, policy, governance, and resource mobilization, including blended finance to leverage private sector financing. The GBFF can receive contributions from public, private, and philanthropic sources. It has streamlined procedures to provide efficient and impactful support for developing countries towards biodiversity goals, with a target of having 20 percent of its funding to support biodiversity action led by Indigenous Peoples and local communities.Grants

Common questions
- What is biodiversity finance?
- Money spent on protecting, restoring and sustainably using nature — through grants, conservation trust funds, results-based payments, blended investment funds, carbon and biodiversity credits, and debt-for-nature swaps.
- Who funds biodiversity projects in developing countries?
- Global environmental funds, bilateral donors, foundations, conservation trust funds, development banks and a growing number of nature-focused investment funds. Grants dominate for conservation; investment funds back nature-positive businesses with revenue.
- Can a private company get nature finance?
- Yes, if it has a revenue model linked to sustainable land or ocean use, such as agroforestry, sustainable timber or deforestation-free commodities. Specialist blended funds and impact investors are the usual route.
- What is the difference between nature finance and biodiversity credits?
- Nature finance is the whole market of grants, loans, equity and payments for nature. Biodiversity credits are one emerging instrument within it, with limited buyer demand so far.
