Private investors - often supported by public policy and finance - are already channeling significant amounts of money into the low-carbon economy in many countries around the world. These projects are bringing energy to communities, improving agriculture yields for small farmers, spurring economic growth, and helping countries mitigate and adapt to climate change. However, much more investment is needed to tackle the scale of the climate challenge. The Global Innovation Lab for Climate Finance is a global initiative that aims to drive billions of dollars of private investment into climate change mitigation and adaptation in developing countries. The Lab supports the identification and piloting of cutting edge climate finance instruments that can drive this investment and unlock new opportunities for action.
