The United Nations Framework Classification for Resources (UNFC) is a global classification and management system applicable to mineral, petroleum, nuclear fuel, renewable energy and anthropogenic resources, as well as injection projects for geological storage. Since the adoption of the Sustainable Development Goals (SDGs), managing energy and raw material resources in a sustainable manner has become paramount to all stakeholders including governments, industry, investors and communities. This updated version of UNFC is intended to satisfy the requirements of different resource sectors and applications, as well as making it fully aligned to the sustainable resource management called for by the 2030 Agenda for Sustainable Development. The key changes, including the normalization of the text, make UNFC applicable for all resources.
