The project aims to develop and advance a set of metrics that complement and go beyond GDP and to strengthen national capacities to design, implement, and integrate beyond-GDP metrics into evidence-based decision-making processes to foster inclusive and sustainable development.The project will be implemented in two sequential and complementary phases: Phase1: Convening of a High-Level Expert Group (HLEG), as requested in the Pact for the Future, and support to its work. Specifically, Phase1 will provide substantive and analytical support to the High-Level Expert Group and its operational functioning. It will help collate available data sources and needs for new measures, as a basis for identifying a limited number of country-owned and universally applicable indicators of sustainable development that complement and go beyond GDP. Phase2: will follow phase1 and build on its outcomes by supporting pilot testing at country level of recommended beyond-GDP metrics. By leveraging innovative methods, AI, and non-traditional data sources, the project will also test their use at the country level. Phase2 will equip governments with tools and guidance to address key gaps in measuring progress. Stakeholder engagement, case studies, and global dissemination of results will further ensure the scalability and sustainability of these new approaches, as well as alignment with the 2030 Agenda.
