The coal industry is the most powerful industry in the United States, and it’s booming.

The coal companies that make it big are the ones that can survive and thrive in the era of cheap natural gas and solar power.

And while the industry’s fortunes have been affected by a series of factors, its most pressing problem is the threat of climate change.

But coal is a carbon-intensive fuel, so it also poses risks to the environment and the health of its workers.

A new report from the Carbon Tracker Initiative finds that coal’s carbon footprint exceeds that of natural gas, natural gas plus nuclear, and all other coal fuels combined.

The analysis finds that the total CO2 emissions from coal-fired power plants in the U.S. have increased by nearly 60% since 1970.

That’s in addition to the roughly $6.4 trillion in additional CO2 that has been released to the atmosphere.

The carbon footprint of the coal sector is about two-thirds that of the fossil-fuel industry combined.

And with the country on track to meet its global climate targets, the industry faces an existential threat. In the U
