Green finance represents both a critical challenge and a transformative opportunity for CAREC countries. In this publication, alignment of financial systems with climate and sustainability objectives is explored, focusing on how this can boost long-term economic stability. The possibilities created by a regional approach, with harmonized regulations and expanded use of instruments such as green bonds and tax incentives to mobilize private capital, are discussed in context of global best practices. A 10-year phased, coherent regional approach is presented as the pathway to shift investment flows to low-carbon and climate-resilient sectors.
