United Nations Framework Classification for Fossil Energy and Mineral Reserves and Resources

The United Nations Framework Classification for Fossil Energy and Mineral Reserves and Resources 2009 (UNFC to 2009) is a universally applicable scheme for classifying/evaluating energy and mineral reserves and resources — it is the successor to UNFC to 2004. Designed as an all-encompassing framework, it enables the incorporation and unification of existing national systems, while allowing their classification units and glossary to be retained. The principal objective of UNFC to 2009 is to enhance international communication by providing a simple, user to friendly and uniform format for the reporting of energy reserves and resources, using market-based economic criteria.
