Introduction

The United Nations Framework Classification for Fossil Energy and Mineral Resources (UNFC) is a universally applicable scheme for classifying petroleum and solid minerals (including energy minerals) reserves and resources. The Classification is designed to allow the incorporation of currently existing terms and definitions into this framework and thus to make them comparable and compatible. This approach has been simplified through the use of a three-digit code clearly indicating the essential characteristics of energy and mineral commodities in market economies.

Sustainable Development Goals:

Affordable and Clean Energy
