The United Nations Framework Classification for Resources (UNFC) is a project-based classification and management system applicable to all energy and mineral resource projects including renewable energy, anthropogenic resource projects 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 such as Governments, companies and investors. This has to be viewed along with the Paris Climate Accord, which seeks low-carbon pathways in the appropriate developmental strategies. Successful resource management in the modern world requires relevant information on the resource base, understanding of the factors that are responsible for progressing the resources to production, adequate framework conditions set by the regulators and society and the enterprising capacity. A series of case studies on various resource projects from different countries are presented in this report to demonstrate how UNFC could be used for sustainable resource management
