The ability to mobilise and leverage different forms of finance, public and private from domestic and international sources, will be key to delivering the steady transition to a low emissions and climate resilient development paradigm. “National Financing Pathways” are put forward here as a concept that articulates the interdependencies between public, private and international sources of finance as a means of delivering scaled investment to support implementation of low emission and climate resilient development. The interplay between national policy objectives and institutional frameworks with various sources of finance can be considered as constituting a national finance ecosystem and so influencing the shape and pace of the financing pathway. Based on discussions with representatives in Chile, Colombia and Peru, this working paper identifies emerging issues that may influence a NFP and considers different frameworks and tools to develop such pathways. These may help to prioritise actions over the short, medium and longer term to deliver a sustainable financing pathway to implement LECR objectives.
