“With news headlines increasingly dominated by images of extreme weather events across the world, from storms, floods, and landslides to extreme temperatures, droughts, and wildfires, there is little doubt that such events are increasing in magnitude and frequency as a result of climate change. There is also little doubt that they are putting the world’s critical infrastructure at risk. Yet, with the cost of adapting to and mitigating the impact of increasing climate change shocks rapidly outpacing the ability of governments to fund the necessary investments, there is a growing need for private sector capital and expertise to step in. However, while there is growing evidence of public-private partnership (PPP) arrangements helping to bring forward investment in large-scale infrastructure, climate resilience is still not being adequately integrated into PPP policy frameworks, jeopardizing the performance of these investments. This is no easy feat, and best practices are still in development.” This report asks, “why and how should climate risk and resiliency be mainstreamed into policy? And at this juncture, what are the leading practices governing the development of infrastructure PPPs?”
