for Climate

The Climate Finance Fund began its journey on the 15th of September 2021.

about us


The Climate Finance Fund is a philanthropic platform that helps to mobilize capital for climate solutions.


CFF focuses on China, the European Union, and the United States.


To keep global warming below 1.5 degrees Celsius, investors must invest between $1.6 to $3.8 trillion annually. Right now, investments total a mere $600 billion annually.


We focus on capital allocators across the supply chain: consumers, small and medium sized enterprises, large non-financial corporations, and banks and asset managers. We also provide expertise to market rule makers, like financial regulators.


We drive change through supporting innovative finance and the systemic decarbonization of capital.
