Ancient flora decomposes under high pressure and extreme temperatures, creating the world's most abundant fossil fuel: coal.
Although coal is plentiful, it is highly concentrated in the regions that favored its formation. The amount that can be discovered and extracted using existing technology and economically sound operational methods is known as proven coal reserve.
The article lists the world’s proven coal reserves possessed by 10 countries. For each nation, it also highlights the types of coal produced and the regions rich in coal reserves.
10 countries with the largest coal reserves in the world
Coal reserves by country in billion short tons:
| Country | Coal reserves (in billion short tons) |
|---|---|
 India | 407.2 |
 United States | 249.4 |
 Russia | 178.757 |
 China | 173.108 |
 Australia | 164.764 |
 Germany | 39.022 |
 Indonesia | 38.641 |
 Ukraine | 37.892 |
 Kyrgyzstan | 31.415 |
 Poland | 30.598 |
1. India
India, a peninsular country, has one of the largest proven coal reserves in the world. As of 1st April 2025, India's Ministry of Coal updated its proven geological coal reserves to 407.2 billion short tons. Indian mines produce bituminous coal in higher concentrations than other types. India's largest coal-producing states are Odisha, Jharkhand, Chhattisgarh, Madhya Pradesh, and West Bengal.
2. United States
The U.S. Energy Information Administration (EIA) estimates its recoverable coal reserves at 249.4 billion short tons, as of Jan 1st 2025. Among the four naturally occurring coal types, America is rich in bituminous coal, the second-highest grade. Wyoming and Montana (Subbituminous) are the states with the largest coal reserves in the U.S.
3. Russia
The nation’s proven coal reserves, as reported by the EIA (2023), are estimated at 178.757 billion short tons. It comprises 13.9% of the world’s coal reserves. Russian mines produce both high-grade anthracite and relatively lower-quality lignite, or brown coal. Kemerovo Oblast (province) in Western Siberia holds the highest share of the country's total coal reserves and is known for producing coking coal.
4. China
China has the world’s fourth-largest coal reserves. The EIA (2023) stated China’s proven coal reserves to be 173.108 billion short tons, which make up 13.5% of the world’s coal reserves. China also has plentiful reserves of bituminous coal, followed by metallurgical (high-grade bituminous) and anthracite coal. Shanxi, Shaanxi, and Inner Mongolia are some of the provinces with the most coal reserves in the country.
5. Australia
The EIA 2023 report shows that this continental country has some of the world’s largest coal reserves of approximately 164.764 billion short tons, accounting for 12.8% of the world’s total coal reserves. In Australia, black coal is a collective term for the three main coal types: anthracite, bituminous, and sub-bituminous coal. These are most abundant in the Queensland and New South Wales districts. Brown coal (lignite) is primarily found in the Gippsland Basin, particularly in the Latrobe Valley.
6. Germany
Germany holds one of the world’s largest reserves of coal. The country has nearly 39.022 billion short tons of proven coal reserves (EIA, 2023) and accounts for 3% of the world's total coal reserves. German mines are rich in lignite coal. Rhineland, Lusatia, and Central Germany have the majority of the nation’s coal.
7. Indonesia
Indonesia’s proven coal reserves are estimated to be 38.641 billion short tons by EIA for 2023. The Southeast Asian nation shares 3.0% of the world's total coal reserves. The nation's mines primarily produce sub-bituminous coal. Indonesia’s prominent coal reserves are located in Kalimantan (Borneo) and the Sumatra islands under Indonesian jurisdiction.
8. Ukraine
Ukraine has 37.892 billion short tons of proven coal reserves, as estimated by the EIA in 2023. Ukraine's coal mines have about 2.9% of the world’s total coal reserves, and they mainly produce bituminous coal. A large share of the country’s coal comes from mines in the Donbas-Donets Basin, which is now under Russian control.
9. Kyrgyzstan
Situated in Central Asia, the landlocked nation of Kyrgyzstan has proven coal reserves of 31.415 billion short tons, according to EIA (2023). Kyrgyzstan shares 2.4% of the world’s total proven coal reserves. Karakeche is a crucial mining area in the Naryn region and contributes significantly to the nation’s coal production. Among the four coal types, the nation produces lignite in large quantities.
10. Poland
Poland has substantial coal reserves. EIA’s 2023 report shows that the country has proven coal reserves of 30.598 billion short tons, about 2.4% of the world's reserves. Used primarily for electricity generation, much of the coal produced by mines is bituminous (steam coal and metallurgical coal). Zofiówka and Marcel coal mines are among the most important locations in Upper Silesia.
