The objective of the project is to build capacities in UNECE member States for sustainable management of resources through application of UNFC and UNRMS. These systems provide a unified, comparable, interoperable and harmonized approach to resource assessment and management usable for governmental, statistical, corporate and financial purposes.  Sustainable management of natural resources underpins socio-economic development. The Expert Group on Resource Management (EGRM) is mandated to develop UNFC, a universally accepted and internationally applicable classification scheme for energy and mineral resources. In its recent work, EGRM has developed UNFC for resources including solar, geothermal, wind and bioenergy, as well as anthropogenic resources, and work is underway on hydro and marine energy and groundwater. UNFC has been endorsed by ECOSOC (Decision 2004/233) for global application. EGRM is also mandated to develop UNRMS as a dynamic system for sustainable management of resources building on UNFC. UNFC and UNRMS represent an integrating toolkit to assist countries to manage their natural resources sustainably in alignment with the 2030 Agenda for Sustainable Development. UNFC- and UNRMS-based classification and management provide the basis for reliable and coherent information on the natural resource base, which can be used for policymaking and directing capital investments. Attainment of the SDGs requires energy and raw materials, but there is a need to make resource production and use more efficient and carbon neutral. Due to the exponential growth in the quantities of resources consumed by society, progress towards a circular economy paradigm has become a necessity. The COVID-19 pandemic has demonstrated the need for secure supply chains for critical raw materials required for diverse social and economic sectors including health, agriculture and low or zero-carbon energy. Near- and long-term implications of countries recovering from the impacts of COVID-19 emphasise the need for resiliency in resource management which will also be a focus of this project.
