Bridging the climate finance gap

Reaching US$1.3 trillion annually by 2035

This report explores global climate finance and the mix of sources and conditions needed to help reach the US$1.3 trillion annual target by 2035, supporting the transition of developing countries.

What will it take to help close the climate finance gap?

Global climate finance is at an inflection point, with pledged funding falling short of the aspirational US$1.3 trillion annual target needed to support effective adaptation and mitigation in developing economies.

Both traditional and alternative funding sources, such as multilateral development banks (MDBs), Article 6-enabled carbon markets, and philanthropic contributions, are expected to be important, along with the strategies and conditions needed to help mobilize finance at scale to support a resilient and sustainable future by 2035.

Bridging the gap

Meeting the world’s climate finance ambitions can be both a challenge and an opportunity. 

Across sources, international climate finance toward emerging markets and developing economies could reach US$269 billion–US$1.5 trillion by 2035, depending on enabling conditions, with the upper end slightly exceeding the aspirational US$1.3 trillion target.

Achieving success calls for greater engagement, more funding, and new ways to help mobilize, structure and deliver finance.
