What to know about the new federal law to help workers protect the climate and their health

U.S. President Donald Trump signed a new federal rule Wednesday that would allow coal mining companies to dump carbon dioxide emissions into the air as part of the clean energy transition.

The rules also would allow people to sue companies that dump pollutants into the atmosphere, a measure that the president’s transition team says is aimed at ensuring the rule remains in place while Trump prepares to leave office.

Trump’s signature of the rule is the latest in a series of regulatory moves the administration has taken to improve coal mining.

The administration says it wants to give miners greater certainty in the future about the clean power they are building and the amount of carbon dioxide that will be emitted, which could lead to higher costs for companies that do not meet the clean-power goals.

The Trump administration says the rule will reduce air pollution and emissions from coal-fired power plants by 25 percent, or roughly 30 million metric tons, by 2025.

The new rule, called the Clean Power Plan, was signed by Trump on Monday.

It is aimed largely at helping coal miners with the costs of complying with the Clean Air Act, the landmark legislation aimed at regulating greenhouse gases and other air pollutants.

But it also applies to those companies that have filed a lawsuit to block the rule, or those that have threatened to sue.

The rule would take effect on Jan. 1, 2020, and go into effect immediately.

It would also require coal companies to pay for carbon capture and storage technology and to buy renewable energy credits from the federal government.

That would provide the administration with a permanent financial lifeline, which the administration says will pay for the clean air protections for the country’s workers.

Coal companies have spent millions of dollars to oppose the rules, arguing that it will hurt them.

Trump says the coal industry will create thousands of new jobs in the U.A.E. and that he would support them in that effort. But the U
