In 2015, the Addis Ababa Action Agenda (AAAA) endorsed the concept of Integrated National Financing Frameworks (INFFs) with the ambition of helping countries to align financing policies and opportunities with long-term national development strategies and consequently to overcome impediments to financing national sustainable development. The Inter-Agency Task Force on Financing for Development (IATF) generated further interest with a whole ad-hoc chapter in the 2019 Financing for Sustainable Development Report (FSDR)1. In 2020, the guidelines on the inception phase were published; the guidance materials for three of the four INFFs building blocks were published the following year2. In June 2021, the G20 officially endorsed the INFFs as well.
