Climate-related shocks and stresses are increasing in frequency and magnitude, causing damages to infrastructure systems and disruptions in the provision of services. Yet there is not sufficient investment needed to infrastructure systems’ climate resilience. The global urban infrastructure investment gap alone is estimated to be over US$4.5 trillion per year, with a premium of 9-27% is required to make infrastructure low carbon and climate- resilient Public-Private Partnerships (PPPs) are a key entry-point to mobilise private sector finance to bridge this gap and must be resilient to climate change and work to build the resilience of the communities they serve. The Climate-Resilient
Infrastructure Officer (CRIO) Handbook provides tools and guidance on how PPP practitioners can best integrate and advocate for climate-resilient infrastructure.
