Financial Innovation
Deploying the trillions needed to address global climate adaptation and mitigation requires more than just shifting investments. It requires novel ways to attract and deploy those investments with financial innovation.

It has particular expertise in combining blended finance models with early-stage technical assistance to ensure bold ideas move from concept to implementation quickly and with as little risk as possible.
