UN Environment and the World Bank Group view the over-arching objective of a sound financial system as being to provide finance that meets the long-term needs of an inclusive, environmentally sustainable economy. While there is no single blueprint or unique pathway for creating such a “sustainable financial system”, it is possible to describe its many characteristics and progress towards it. The Roadmap initiative intends to design an action plan that moves towards a sustainable financial system, including its elements, sequencing and principal actors, and a basis for measuring progress. The Roadmap will build on the extensive experience of both partners and many other active in the field.
