National development banks play a key role in financing infrastructure projects in developing countries and mobilizing private capital for climate-compatible infrastructure. However, to attract more commercial investors, these banks will need to go beyond traditional project financing to support new market creation. The discussion will address how national development banks can mobilize private financing through their institutional mandates, incentives for crowding in new sources of funding, and strategic use of concessional resources. Key questions center around how the role of these banks is changing amidst large infrastructure needs, their value in enabling low-carbon development, and how they can help build private investment markets for climate-friendly infrastructure.
