Murray is a director of the National Mining Association, the American Coal Foundation, and the National Coal Council.
Murray has described global warming as "hysterical global goofiness."
In his 2007 testimony before Congress, Murray said, "The hysterical and out-of-control climate change or global warming issue, and the legislation that you have proposed, will lead to the deterioration of the American standard of living and the accelerated exportation of more of our jobs to China and other developing countries, which have repeatedly advised, as recent (sic) as last week, that they will not limit their carbon dioxide emissions."
Referring to Rachel Carson: "She and her environmental followers killed millions of human beings around the world with the ban on DDT, which has since been found by the World Health Organization to be very safe to humans in controlling global epidemics."
Explaining employee benefit cuts: "Murray Energy's inability to provide these benefits is, in part, due to the destruction of the coal industry, including our markets, by the Obama Administration and its appointees and supporters, who have eliminated the livelihoods of thousands of coal miners, and their families, by the forced closing of 392 coal-fired electric power plants in America, now and in the immediate future."
Murray Energy is the 71st greatest global warming polluter of all time.
While Murray has emphasized his company's concern for worker health and safety, from 2000 to 2009 the federal Mine Safety and Health Administration cited Murray Energy for over 7,700 "significant" violations resulting in $18 million in fines, including a record $1.8 million fine for a 2007 collapse at the company’s Crandall Canyon Mine in Utah, which killed six miners and three rescue workers. After the collapse, Murray offered to let miners relocate to other mines, but only if they took a pay cut. A 2008 MSHA report concluded the mine was “destined to fail” because the company didn’t report early warning signs.
Murray gave over $230,000 to conservative candidates and PACs in the 2012 election cycle, including $30,000 to House Speaker John Boehner and $5,000 to Wisconsin's union-busting governor, Republican Scott Walker.
In 2012 Murray hosted a $1.7 million fund-raiser for Mitt Romney, making employee attendance mandatory without pay.
Days after Obama's 2012 re-election, Murray fired 163 of his employees, claiming Obama's "war on coal" made it impossible for new coal plants and jobs to thrive.
Murray announced that in August 2014, over 1,000 ex-miners would lose their promised health benefits, blaming Obama's "war on coal."
In 2013, Murray unsuccessfully sued blogger Mike Stark for defamation and invasion of privacy after the blogger published an article on Huffington Post highlighting a $30,000 donation that Murray made to Virginia Republican Ken Cuccinelli's gubernatorial campaign.
In 2014, Murray appointed climate denier Steve Milloy to be the company's Director of External Policy and Strategy.
In March 2014 Murray sued the EPA, claiming that the agency's air pollution regulations are illegally causing coal mines to shut down.
