This report identifies ways to overcome key barriers to private sector investment in adaptation and resilience, laying out a coordinated and data-driven Blueprint for Action to help governments and their development partners to close the adaptation finance gap. Although climate adaptation finance flows have increased by 35% in recent years, they still fall short of what is needed to avoid severe economic and human impacts from climate change. The urgent need for boosting investment in climate adaptation and resilience cannot be overstated. The blueprint provides five entry points to enable private investment. The Blueprint for action we propose in the report represents a novel coordinated framework for action for governments to develop, finance, and implement priority adaptation and resilience investments – driven by countries’ goals and national investment plans that can help accelerate and scale up investment to address the climate resilience needs of the world’s most climate-vulnerable communities and economies.
