Financing the climate transition today is one of the biggest challenges of sustainable development. Just to recover degraded areas in the Amazon, Cerrado, and Atlantic Forest, it would be necessary... US$ 1 billion per year until 2030, According to estimates from The Nature Conservancy. On a global scale, the scenario is no different: at COP29, held in Baku in 2024, negotiators reached the goal of achieving US$ 300 billion per year by 2035, with an expansion trajectory that could reach US$ 1.3 trillion annually in total climate fluxes.
The problem is not just the volume of resources required.. It's also the way these resources circulate. Socio-environmental projects often present a risk, return, and liquidity ratio that is very different from what traditional private capital is willing to accept. This asymmetry It drives investors away precisely from the initiatives that most need capital. and that's where the blended finance It is beginning to gain traction as a strategic response.
What is blended finance?
Blended finance, or mixed financing, is the a combination of funding sources (public, concessionary, or philanthropic capital) with private capital.. In practice, it functions as an adjustment mechanism: it reduces risks, rebalances returns, and makes projects that would not get off the ground financeable under normal market conditions.
This structure rests on two large pillars. On one side is the catalytic capital, It is the person who, originating from philanthropic, public, or development sources, enters the preparation, training, and development phases of the project. absorbs part of the initial risk. On the other side is the commercial capital, attracted to supply the other party, more aligned with the return expectations of the traditional market.
It's worth reiterating: blended finance It's not a specific financial product, but rather a strategy. She reconfigures the A balance between risk and return is needed to make projects with a positive impact viable., especially in contexts where traditional credit typically doesn't work.
Pillars that support this financial engineering.
In practice, the structures of blended finance They rely on three fronts of risk mitigation, that act in a complementary way. Guarantees and risk insurance They reduce the likelihood of losses for investors and improve credit conditions. concessional capital It operates with more flexible rules, absorbing portions of the risk to encourage the entry of private capital. And the technical assistance It supports beneficiaries in implementing projects, reducing operational obstacles and improving the financial and environmental performance of the initiatives.
Together, these three elements allow for the complete reconfiguration of a project's capital structure, from initial design to the maturity required to attract commercial investors.
Why does this matter so much for climate finance?
In 2009, developed countries pledged to allocate US$ $100 billion per year to developing countries for climate action.. That promise remains unfulfilled, and the The funding gap is only widening.. Given this scenario, institutions such as the G20, the UN, the OECD, the International Energy Agency, and various development finance institutions began to see the... mixed financing as one of the most promising tools for reduce the gaps climate finance and the SDGs, mobilizing private capital that would not otherwise invest in these projects.
Market figures confirm this growing relevance. According to the State of Climate Blended Finance Fall 2025, the global market of blended finance mobilized US$ 15.5 billion in 84 transactions in 2024 — the second highest volume in the last six years. Climate remains a central focus of these operations., accounting for 70% of all investment flows mobilized between 2019 and 2024, directed towards initiatives of mitigation and adaptation.
There is also a multiplier effect worth highlighting. A study by the collaborative initiative Go!Blended shows that, For every R$ 1 in catalytic investment, another R$ 4 are generated in commercial capital.. This leverage effect not only expands the reach of projects but also generates direct impacts on the tax chain, creating a virtuous circle between public revenue and positive socio-environmental impact.
The challenge is not just financial.
Industry experts often point out that the biggest obstacle to blended finance It's not in financial engineering itself, but in governance. Structuring a blended operation means...bringing together partners with very different cultures, priorities, and ways of working. — multilateral banks, third-sector organizations, private and philanthropic investors — all working together on a single project. This It requires a robust governance structure and, above all, a willingness to work together.No single actor has the capacity to make projects of this scale and complexity viable.
This is also one of the reasons why the blended finance It has proven especially effective in scaling up projects by small producers and cooperatives, essential actors in the climate transition, but who would hardly have access to financing through conventional means.
Putting blended finance into practice
To finance the sustainable development in tune with Agenda 2030 from the UN, the structures of blended finance They use catalytic capital strategically: first to mitigate the risk of impact projects, then to attract commercial capital on a large scale. Each actor contributes the type of capital they have available and receives, in return, what is most relevant to their strategy—socio-environmental impact, financial return, or a combination of both.
The central challenge remains the same: Balancing risk and return to attract private capital without losing sight of maximizing impact.. It is precisely to support organizations in overcoming the complexity of governing and operating these structures that Having an experienced partner makes all the difference..
