The world is facing a $15 trillion infrastructure investment gap by 2040. Public-Private Partnerships (PPPs) can help countries mobilise the private sector finance required to enhance the resilience of infrastructure systems to the impacts of climate change. 
 
To scale climate-resilient infrastructure globally, GCA developed the Climate-Resilient Infrastructure Knowledge Module, which includes the Climate-Resilient Infrastructure Officers (CRIO) Handbook, practical Masterclasses, and CRIO Certification programs. These initiatives bridge the gap between theory and implementation by providing hands-on training and recognized professional credentials for infrastructure practitioners. The Masterclass series has expanded globally, reaching stakeholders from ministries, PPP units, infrastructure agencies, the private sector, and academia. The program has demonstrated that Masterclasses are highly effective in creating dialogue between public and private actors, aligning incentives, and improving the bankability of resilient infrastructure projects while strengthening institutional capacity to integrate resilience into infrastructure planning and operations.
