«In Australia, nearly 80% of coal is produced from open-cut mines, in contrast to the rest of the world where open-cut mining only accounts for 40% of coal production. Open-cut mining is possible because coal seams are close to the surface. Such mining is cheaper than underground mining and enables up to 90% recovery of the resource. Many brown coal beds lie close to the surface and can be hundreds of metres thick, so can be extracted easily and cheaply. Firstly the topsoil is removed and stored for use later in restoring the disturbed land. The surface rock (called overburden) covering the coal is then blasted with explosives and removed by excavators. The uncovered coal is in turn then blasted to break up the layers and loaded into large trucks which can hold up to 300 tonnes of material. The coal is transported to the processing plant where impurities are removed.» [Geoscience Australia]
Le riserve australiane di carbone sono stimate essere 159.634 miliardi di tonnellate, ne estraggono 554.764 milioni di tonnellate l’anno, e ne esportano 427 milioni di tonnellate [Fonte]
Recentemente alcuni funzionari UN hanno rimproverato l’Australia.
«The United Nations’ top climate official has urged Australia to have a “more honest and rational conversation” about urgently abandoning coal power, which he said was in the nation’s and the world’s best interests.
Selwin Hart, UN Assistant Secretary-General and Special Adviser to the Secretary-General on Climate Action, said wealthy nations must stop using coal power by 2030 and the rest of the world must dump it by 2040 if the world is to keep global warming to within the agreed target of 1.5 degrees Celsius.» [Fonte]
La frase “wealthy nations must stop using coal power by 2030 and the rest of the world must dump it by 2040” soffre del solito, grossolano, errore, di considerare che l’enclave occidentale liberal sia il “mondo”, falsità grossolana.
«China is planning to build 43 new coal-fired power plants and 18 new blast furnaces — equivalent to adding about 1.5% to its current annual emissions — according to a new report. The new projects were announced in the first half of this year despite the world’s largest polluter pledging to bring its emissions to a peak before 2030, and to make the country carbon neutral by 2060.»
«The news shows that at least some in China are prioritizing economic growth over emissions reductions — although some analysts say they are still optimistic that China will reach its climate targets. “There is this desire in the Chinese political and economic system to keep on building, to continue the infrastructure fever,” says Li Shuo, a senior global policy adviser for Greenpeace in Beijing.»
«coal accounted for 56.8% of China’s domestic energy generation in 2020 …. China is still increasing construction of coal-fired power plants»

«China, the world’s biggest coal consumer, saw overall consumption of the fossil fuel increase by 0.6% in 2020 from a year earlier to around 4.04 billion tonnes. …. China churned out 3.84 billion tonnes of coal in 2020, the most since 2015»

Come si constata, il resto del mondo, Cina in testa, non ha la minima intenzione di ridurre l’estrazione e l’uso del carbone.
Adesso, al resto del mondo si associa anche l’Australia.

Le Nazioni Unite? Ma chi mai sono e chi mai si credono di essere da pretendere di dare ordini all’Australia?
Melbourne, Sept 6 (Reuters) – Coal will be a major contributor to Australia’s economy well beyond 2030 given growth in global demand, the country’s resources minister said on Monday, a day after a United Nations envoy called on the country to phase out the fossil fuel.
Without greater efforts to cut coal, climate change will dramatically damage Australia’s economy, Selwin Hart, the United Nations special adviser on climate change, said in a speech in the capital Canberra on Sunday.
Australia’s heavy reliance on coal-fired power makes it one of the world’s largest carbon emitters per capita, but its conservative government has steadfastly backed fossil fuel industries, saying tougher action on emissions would cost jobs.
Australia’s latest export figures show “the reports of coal’s impending death are greatly exaggerated and its future is assured well beyond 2030,” Resources Minister Keith Pitt said in a statement.
In the three months to July, Australian coal exports grew 26% in value to A$12.5 billion ($9.3 billion), he noted. Coal prices have climbed as global economies recover from COVID-19 restrictions.
“The future of this crucial industry will be decided by the Australian government, not a foreign body that wants to shut it down costing thousands of jobs and billions of export dollars for our economy,” Pitt added.
The U.N. has called for phasing out coal by 2030 in Organisation for Economic Co-operation and Development countries, which include Australia.
In July, energy and environment ministers from the Group of 20 big economies failed to deliver a deal to phase out coal by 2025. But some experts said there were chances of progress at U.N. climate talks in Glasgow in November.
Prime Minister Scott Morrison has said Australia is on a path to net zero carbon emissions but has stopped short of committing to a timeline. He has said that Australia would update its 2030 emissions projections going into the Glasgow talks.
