In 2024, developed countries reported US$101.6 billion in public climate finance. But our analysis found that actual payments against those commitments stood at US$60.4 billion.
The money is also unevenly distributed.
Seven countries home to 43% of people living in extreme poverty received just 11% of climate finance payments to developing countries.
And with aid budgets shrinking, the stakes are getting higher.
So where is the money going? And how much of what governments promise actually reaches the countries counting on it?
Our new ONE Data report, The gap between promises and payments, reveals where climate finance is going, how much money countries actually receive and why better data matters.

Africa's young people have the talent, ideas and ambition to shape the continent's future. But talent alone isn't enough.
Investing in young entrepreneurs, expanding access to opportunities and backing African-led solutions can turn great ideas into thriving businesses, create jobs and drive lasting economic growth. 🌍
It's time to match Africa's young talent with the partnerships and opportunities they deserve.

The conversation about Africa's health security needs to shift from what the continent lacks to what it can achieve with the right investments.
At the #WorldHealthSummit in Berlin, ONE Africa Executive Director Serah Makka highlighted why strengthening Africa's existing capabilities must be a priority. 🌍
When a health crisis strikes, the speed of a country's response can make all the difference.
That means building systems that can detect threats early, mobilize resources and respond effectively, without depending entirely on external support.
Partnerships should strengthen that readiness, not replace it.

The goal isn't simply to prepare for the next health emergency. It is to build health systems that are resilient long before one happens.
A future where African countries can develop and deliver their own health solutions is a future where the entire world is better prepared.
That's what sustained investment can make possible.

Every girl deserves more than the chance to dream about her future.
She deserves the chance to shape it.
That means being able to learn, lead, create, make decisions about her own life, and have a real say in the decisions shaping her future.
This International Day of the Girl Child, we are celebrating girls everywhere who are already showing us what’s possible — and standing for a future where equality and opportunity aren’t determined by where you’re born or whether you’re a girl.
Know a girl whose ideas, courage, and leadership inspires you?
Celebrate her in the comments.👏🏽
Young people have a huge role to play in shaping what Africa becomes next.
And if you’re a young African, that includes you.
The ideas you pursue, the businesses you build, the stories you tell, the solutions you create and the communities you strengthen all have a part to play in shaping the future. 🌍🤝🏽
There’s no single way to contribute, either. Your creativity, ambition and perspective all matter — whether what you’re building feels big or small right now.

We are proud to announce that ONE President and CEO, Amb. Mark Green (ret.), has been named by the German government as a Commissioner of the new South-North Commission on Development – an important opportunity to help shape what comes next for global development.
Co-chaired by former German Chancellor Olaf Scholz and former Costa Rican President Laura Chinchilla, the Commission will bring together leaders from across countries and regions to tackle shared global challenges, strengthen international cooperation, and help shape the global development agenda beyond 2030.
Mark brings decades of experience in diplomacy and global development to the role — from serving as USAID Administrator and U.S. Ambassador to Tanzania to helping craft the bipartisan legislation that established PEPFAR and the Millennium Challenge Corporation.
As Mark puts it:
“No country can solve today's global challenges alone. What unites us must count for more than what divides us. The world doesn't need another report that looks good on paper and changes nothing. We are setting the bar high – solutions that genuinely improve people's lives.”
