The open-pit mine was approved by the Queensland Government and the federal Australian governments. Exports are planned to leave the country via port facilities at Hay Point and Abbot Point after being transported to the coast via rail. The mine has drawn immense controversy about its claimed economic benefits,  its financial viability, plans for government subsidies and the damaging environmental impacts. Broadly, these have been described as its potential impact upon the Great Barrier Reef , groundwater at its site and its carbon emissions.
Queensland extinguishes native title over Indigenous land to make way for Adani coalmine
Adani Coal Mine: The World's Most Insane Energy Project Moves Ahead - Rolling Stone
The Adani group has launched its own rail business to haul coal to its Queensland port, while avoiding any public mention of the parent company or the controversial Carmichael mine. It follows years of pressure from anti-coal activists that has prompted a string of potential Adani contractors to walk away from the mining giant, increasing the cost of doing business. Head of project delivery, David Wassell, said the company had bought its own "state-of-the-art locomotives and rollingstock" and would recruit about 50 workers. Neither the media release nor the company website mention Adani or the Carmichael mine. The other two rail operators with capacity to haul Adani's 10 million tonnes of coal a year — Aurizon and Pacific National — have come under activist and shareholder pressure to follow suit. A spokesman for Aurizon told the ABC it was, "not aware Adani has commenced any commercial process with regard to the tender of above-rail haulage contracts or indeed whether they intend to".
Australia gives approval for work to begin on controversial new coal mine
At reasonable costs for production, transport, finance and infrastructure, its low-grade coal would be far more expensive than comparable product available elsewhere. Fueling its power stations at the cost needed to make Carmichael stand up would make matters even worse. Still, looking at the way the company values its own project shows just how generous your assumptions must be to believe this mine can actually make money. A discount rate of Still, it looks generous compared to other Australian coal mines.
Explaining Adani: why would a billionaire persist with a mine that will probably lose money? The only glimmer of hope for coal has been in less developed countries in Asia. But over the course of this year, even these hopes have dimmed. Major banks in Japan and Singapore have withdrawn from funding new coal projects, following the lead of the global banks based in Europe and the US.
