In 2015, Pacific Island leaders issued the "Suva Declaration On Climate Change" during the Pacific Islands Development Forum in Suva, Fiji.They called for "the implementation of an international moratorium on the development and expansion of fossil fuel extracting industries, particularly the construction of new coal mines, as an urgent step towards de-carbonising the global economy."
The Biden administration on Thursday proposed an end to new coal leasing from federal reserves in the most productive coal mining region in the U.S. as officials seek to limit climate-changing ...
The technique can be applied to coal resources that are otherwise unprofitable or technically complicated to extract by traditional mining methods. UCG offers an alternative to conventional coal mining methods for some resources. It has been linked to a number of concerns from environmental campaigners. [2]

Enhanced coal bed methane recovery is a method of producing additional coalbed methane from a source rock, similar to enhanced oil recovery applied to oil fields. Carbon dioxide (CO 2) injected into a bituminous coal bed would occupy pore space and also adsorb onto the carbon in the coal at approximately twice the rate of methane (CH 4), allowing for potential enhanced gas recovery.

For the first time completely deserted coal mining technology has been used by the Chinese concern «China National Coal Group Corp. (CME)» at the mine «Tang Shan Gou» (longwall mining, shearers, three lava, depth 200 m), and at the mine «Nan Liang» (one plow, depth 100 m). Both coal mines have coal layer thickness 1–1.7 m.

Physical cleaning of coal usually involves gravimetric processes, often in conjunction with froth flotation Such processes remove minerals and other noncombustible components of coal, exploiting their greater density vs that of coal. This technology is widely practiced. Coal can also be cleaned in part by chemical treatments.
