With mandates increasingly aligned around ESG, climate, and SDG-linked outcomes, collaboration between ECAs, MDBs, and DFIs is becoming central to the delivery of large, complex projects. This session examines how joint structures, parallel tranches, blended facilities, and shared due diligence are reshaping project and development finance. The discussion considers the practical benefits including scalability, and risk-sharing, as well as the challenges of aligning standards, climate frameworks, and institutional priorities in higher-risk markets.
