2020-09-01· BHP's Queensland coal mines generate the most operational greenhouse gas emissions among any of the miner's global divisions, accounting for more than a third of the total in fiscal 2019, according to company filings. The mining industry overall accounts for about 22% of the world's industrial emissions, BloombergNEF said in a March report.
Coal is the single biggest contributor to anthropogenic climate change. The burning of coal is responsible for 46 % of carbon dioxide emissions worldwide and accounts for 72% of total greenhouse gas (GHG) emissions from the electricity sector.
A new site-specific (Tier 3) method has been developed to determine greenhouse gas emissions from open coal mining. The Tier 3 method presented here is based on extensive measurement of gas emissions from open-cut coal mines and the physics of gas desorption from coal.
2017-07-10· Queensland's fugitive greenhouse gas (GHG) emissions—the emissions lost to the atmosphere during coal and gas mining activities— have grown very strongly from 3.1 million tonnes of carbon dioxide equivalent in 1990 to reach 13.6 million tonnes in 2014. This strong growth in fugitive emissions is a result of expansion in Queensland's coal and gas extractive industry. Fugitive emissions ...

Between 1990 and 2018, emissions increased by 20.9%, or 126 Mt CO 2 eq. Canada's emissions growth over this period was driven primarily by increased emissions from mining and upstream oil and gas production as well as transport.. Emissions in 2018 were almost equal to 2005 emissions, with a difference of 0.4 Mt CO 2 eq or 0.1%. Emissions from public electricity and heat production by utilities ...
In the United States, "gassy" mines are defined as mines that emit more than about 2,800 to 14,000 cubic meters per day (m3/d) of methane2in coal mine ventilation emissions.
2020-09-02· Multinational mining major BHP plans to reduce scope two emissions at its Queensland coal mines by 50% by the year 2025. According to BHP, the 50% reduction is based on emissions levels from the company's 2020 fiscal year. Credit: Emilian Robert Vicol from Pixabay.
2019-02-05· A study released in the journal Nature on Tuesday shows a steady growth in China's methane emissions, primarily from the country's massive coal mining sector, undermining Beijing's claims to be leading the world on climate change action. "Methane emissions in China appear to be increasing, business as usual.

4.In 2016, methane emissions from coal mining and abandoned coal mines accounted for about 9% of total U.S. methane emissions and nearly 1% of total U.S. greenhouse gas emissions (based on global warming potential). Some mines capture and use or sell the coalbed methane extracted from mines.
Methane emissions from Hunter coal mines go .More needed to be done to monitor and reduce the greenhouse gas emissions from Hunter coal mines, the authors of a study on methane emissions have found. Associate professor Bryce Kelly and Charlotte Lverach from the University of NSW's Connected Water Initiative recently carried out an analysis of methane emission's from the region's mines.
Beijing, People's Republic of China, December 2, 2004 - The People's Republic of China has signed the first ever greenhouse gas emission reductions purchase agreement (ERPA) for a coal mine methane project.

2019-11-10· Wrong time because the GHG emissions of the coal mine and its coal product will increase global total concentrations of GHGs at a time when what is now urgently needed, in order to meet generally agreed climate targets, is a rapid and deep decrease in GHG emissions. These dire consequences should be avoided.
Greenhouse gas emissions by China are the largest of any country in the world both in production and consumption terms, and stem mainly from coal electricity generation and mining. When measuring production-based emissions, China emitted over 12 gigatonnes (Gt) CO 2eq of greenhouse gases in 2014; almost 30% of the world total.
Methane from coal seams in mines—coal mine methane (CMM)—is extracted to the surface using ventilation of underground excavations and installations used for methane drainage [ 4, 5 ]. According to a previous study [ 6 ], the potential to create a greenhouse effect due to methane is estimated to be 28–34 times higher than for carbon dioxide.
2020-08-26· NSW planning minister Rob Stokes promptly proposed legislative amendments that would prevent planning authorities from taking scope-3 emissions into account, including emissions from coal produced in New South Wales but that is ultimately burnt overseas, but the amendments have effectively stalled and were opposed by a parliamentary committee tasked with reviewing the amendments.

Of all the gases present in coal, methane is of greatest concern as an emission source due to its relatively high potency as a greenhouse gas. Methane is also a safety concern, particularly in the enclosed working areas of underground mines. Methane can be handled safely if appropriate precautions are taken.
In an Australian first, development consent for a new coal mine was refused by the Land and Environment Court of NSW (the Court) for reasons that included its material greenhouse gas (GHG) emissions and contribution to climate change.
Table 2shows the volume greenhouse gas emi tted annually from a mine given a range of coal production and specific gas emission. Using the same example of a mine producing 4.0 million tonnes per annum, with an SGE of 20 m 3 /t, the annual gas emission would be equivalent to 1.14 million tonnes of carbon dioxide.
