Development and the changing climate will both require a substantial increase in green infrastructure investment over the next few decades in emerging market and developing countries (EMDEs). The need for investments collides with limited fiscal space in EMDEs, an obstacle that has been aggravated by the multiple shocks faced by those economies in the last few years. At the same time, those investments potentially dovetail with excess financial savings in advanced economies (AEs). In this chapter, we explore how a bridge connecting excess savings in AEs and green infrastructure investment in EMDEs might be built.

In order to close the financing gap in green technologies, finding new mechanisms to enhance the participation of the private sector, combined with that of the public sector, in financing sustainable and climate-resilient infrastructure is a must. In this context, some unlisted instruments are going to be needed to enhance financing of green infrastructures. Besides, the development of properly structured projects, with risks and returns in line with the preferences of the different types of investors and financial agents that make up the ecosystem of financing sources, would also help to close the private financing gap in infrastructure.
