The coal industry is booming, but what does it mean for the climate?

The coal industry has become a cornerstone of the U.S. economy in recent years.

It’s the largest source of carbon dioxide emissions in the nation and employs more than half of the nation’s coal miners.

But according to the National Mining Association, nearly 70 percent of the coal mined in the U, D.C., and Appalachia is exported.

In recent years, the industry has seen a surge in environmental regulations and regulatory hurdles to access, making it more difficult to access coal in the country.

And there are concerns that the industry is undercutting U.s. efforts to curb carbon emissions.

While many coal companies have done a pretty good job of meeting their obligations under the Clean Power Plan (CPP), a rule that would limit carbon emissions from existing power plants, some are still failing to meet them.

That’s where a new study by the National Coal Association comes in.

The coal trade group released the report last week in response to President Donald Trump’s Executive Order to create a new task force to tackle coal pollution.

The group claims the coal industry’s reliance on exports has been one of the biggest impediments to achieving the goals of the Clean Energy Innovation Act (CEIA).

As a result of its recent actions, coal exports from the U of C and the District have dropped from about 2.5 million tons to less than 800,000 tons in 2017.

This has resulted in lower exports and lower carbon emissions than expected.

The study also found that coal export volumes are up from 2016 to 2017, but that the volume of new exports from coal-producing states like West Virginia, Wyoming, and Kentucky has been less than half the volume expected.
