As of late 2021, the Earth holds an estimated 1,161 billion short tons of proved recoverable coal reserves.
Understanding Global Coal Reserves
This significant figure, estimated as of December 31, 2021, represents the amount of coal that has been identified and is considered both technically and economically feasible to extract with current technologies. To put it into perspective, 1,161 billion short tons is equivalent to approximately 1.16 trillion short tons. It's important to understand that this is a dynamic estimate, influenced by various factors.
What Defines "Proved Recoverable Reserves"?
The term "proved recoverable reserves" refers to coal deposits that meet specific criteria:
- Proved: The quantity of coal has been thoroughly demonstrated through extensive drilling, geological mapping, and other exploratory methods, indicating a high degree of certainty about its existence.
- Recoverable: It can be extracted using existing mining technologies and methods, considering geological conditions and safety standards.
- Economically Viable: The extraction and processing of the coal are profitable under current market prices and operating costs.
This definition means that the total amount of coal existing geologically within the Earth is far greater, but only a fraction is classified as proved and recoverable under present conditions.
Geographic Distribution of Coal Reserves
A substantial portion of the world's proved coal reserves is concentrated in a relatively small number of countries. This geographic concentration plays a crucial role in global energy landscapes and supply chains.
Roughly 75% of the world's proved coal reserves are concentrated within just five countries. This highlights how a few nations hold the majority of this vital energy resource.

| Other Countries | 25% |
Dynamic Nature of Coal Reserves
Estimates of proved recoverable coal reserves are not static. They can change over time due to several factors:
- New Discoveries: Continued exploration can lead to the identification of previously unknown deposits.
- Technological Advancements: Innovations in mining techniques can make previously inaccessible or uneconomical coal deposits viable to extract.
- Economic Shifts: Changes in global energy prices or extraction costs can alter the economic viability of reserves.
- Environmental Policies: New regulations or carbon pricing mechanisms can impact the profitability and desirability of extracting certain coal reserves.
While the Earth possesses vast quantities of coal, the figure of 1,161 billion short tons represents the current, most reliable estimate of what is practically available for use under today's conditions.
