Coal producers. The largest coal producing countries are not confined to one region - the top five hard coal producers are China, the USA, India, Australia and Indonesia. Much of global coal production is used in the country in which it was produced; only around 15% of hard coal production is destined for the international coal market.

The total world production of coal increased from 2224.6 million tons of oil equivalent in the year 1991 to 33336.9 million tons of oil equivalents in the year 2009.
