The decision states that the EPA overstepped its authority when it imposed caps on emissions from power plants.

The decision states that capping carbon dioxide emissions at a level that will force a nationwide transition away from the use of coal to generate electricity may be a sensible solution to the crisis of the day.

Congress has the power to make a decision of such magnitude and consequence.

The decision is likely to have broad implications according to Deborah. She says that the court is limiting what the EPA can do. The opinion seems to be a blow for agency deference, meaning agencies beyond the EPA could face limitations in the future.

The ruling is the latest in a string of bombshell cases from the court. The majority opinion was authored by Chief Justice John Roberts and he was joined by other conservatives. The justices disagreed.

What is the decision all about?

There was a question of how much power the EPA should have to regulate carbon emissions. The Clean Power Plan was issued by the EPA.

Each state was required to submit a plan to cut emissions from power plants under the Clean Power Plan.

The Clean Power Plan was put on hold by the Supreme Court after several states and private groups challenged it. After a repeal of the plan during Donald Trump's presidency, a Washington D.C. district court ruled that it was within the EPA's authority.
