The EPA has proposed limits for CO₂ pollution for new fossil-fuel power plants.

New coal-burning plants will have to use carbon capture. It will be difficult to do that at the scale required to make a difference.

I wonder whether the rules count greenhouse gas emissions from extraction or the fuel. This is important because fracked gas involves substantial carbon emissions, and leaks methane.

The argument that this won't do any good while India and China increase their emissions is fallacious. The US (like every country) needs to set an example to convince other countries to do more.

As for putting coal miners out of work, that's simply necessary in order to use less coal. The mining companies, by using mountaintop removal, put far more miners out of work.
