Toledano, Perrine; Vega, Ana M. Camelo; Wilke, Tucker

Blended finance has the potential to help close the sustainable development financing gap. Strategically combining public and philanthropic capital to unlock private investment, it has proven to be an effective tool to de-risk impact investments. But without bold, structural reform, it risks remaining a niche tool – promising in theory, underperforming in practice. Drawing on over 65 expert interviews and in-depth analysis, this report from the Columbia Center on Sustainable Investment (CCSI) maps the systemic barriers preventing blended finance from operating at scale, and outlines a practical path forward. With bold leadership and coordinated reform, blended finance can become a mainstream channel for sustainable investment at scale.
