Coal, which is primarily used as a liquid fuel, in cement manufacturing, steel production and electricity generation, accounts for an estimated nine per cent (9%) of total methane emissions worldwide. (Global Methane Initiative 2018; World Coal Association 2017). The top 10 coal producers worldwide account for 90% of total coal emissions: China, India, USA, Australia, Indonesia, Russia, South Africa, Germany, Poland, and Kazakhstan. (IEA. 2017.)
According to the International Energy Agency, total coal production declined more than ever since the IEA began its recordings in 1971, with a drop of 458 Mt down to 7.268.6 Mt in comparison to 2015, despite the fact that India, Russia, and Indonesia increased production in 2016.
The World Coal Association states that around 15 percent of all hard coal production is destined for the international coal market, with the largest exporters being Australia, Indonesia, Russia, Colombia, South Africa, USA, Netherlands, Canada, Mongolia and Kazakhstan. China is the leading importer of coal, followed by India, Japan, Korea, Chinese Taipei, Netherlands, Germany, Turkey, Malaysia and the Russian Federation. (IEA 2017.)
Furthermore, the World Coal Association states that coal is a fossil fuel, i.e. the transformed residues of prehistoric vegetation, developed and formed throughout millions of years into energy containing coal. Greenpeace lists strip mines as the most harmful since it leaves permanent scars on the environment, including soil erosion and ruination of agricultural land, leading to the pollution of waterways when topsoil is being washed by rain, mixing up natural landscapes.
Another environmental problem caused by coal, estimated by Greenpeace, are coal fires that can burn for decades, or even centuries, polluting our environment with chemicals and toxins that are invisible to the human eye. Greenpeace, which is campaigning to stop investments to any fossil fuel projects, has witnessed and published a case study/full report about Coal Mines Polluting South Kalimantan ́s Water. (Greenpeace, December 2014.) The report summarizes and reveals that intensive coal mining activities in this Indonesian region has led to the release of toxic pollution from coal mining into rivers while violating national standards for wastewater releases from coal mines.
While the damaging nature and risks of coal mining for the overall environment is well-known, the World Coal Association aims to develop and lead the global coal mining industry into a “pathway of zero emissions from coal” with advanced clean technologies allowing for the coal mining industry to minimize its impacts on the environment. The World Coal Association suggests that HELE power generation could reduce CO2 emissions from coal mining by more than a third.
How about methane emissions from coal mining? The United States Environmental Protection Agency EPA estimates that methane emissions from coal mining will continue to increase and be responsible for nine per cent (9%) of total global methane emissions by 2020, whereby methane is many times more powerful as a greenhouse gas than carbon dioxide. According to various estimations, methane (CH4) is up to 25 times as powerful as a greenhouse gas in comparison with carbon dioxide (CO2).

Note from author: I originally wrote and published this article on December 4th 2017 on my website annemariayritys.com and on LinkedIn as a part of my climate change research. USGS states that in addition to peat, which is a precursor to coal, the four actual types of coal are anthracite, bituminous, subbituminous, and lignite. According to Leonard, Michaelides, and Michaelides (Energy Conversion and Management Volume 164, 2018), the substitution of coal with renewables can be optimized but not fully replaced. The World Coal Association lists electricity generation, steel production, cement manufacturing and the usage of coal as a liquid fuel as the four most significant purposes of the global coal industry. Moreover, the construction industry worldwide accounts for the vast majority of the need for steel and cement, which are used as building blocks in most of construction, unless cement and steel are being replaced with other options.
