This document discusses the financing needs for achieving sustainable development goals after 2015. It identifies several components of post-2015 development finance, including domestic public and private financing as well as international public and private financing. Official development assistance remains crucial, especially for low-income countries, but domestic resource mobilization and private capital will also be important. A variety of financing sources are needed and should be seen as complements rather than substitutes. Ensuring adequate financing from all sources will be key to achieving post-2015 development goals.
