Seems like the main points are that they are not going to propose again the same rules which were ruled unconstitutional, and adjust how aggressive the targets are. > “It could foreclose a new administration from doing something more ambitious,” she said.

> Seems like the main points are that they are not going to propose again the same rules which were ruled unconstitutional It wasn't ruled unconstitutional, it was stayed by the Supreme Court while a lower court decided if the rule was within the EPA's regulatory power under the Clean Air Act.

> If the Supreme Court rules that the EPA "only has authority over environmental infractions at individual plants, like chemical spills and improper handling of hazardous materials", a rule from the EPA like this might not be possible again.
AFAIK the Supreme Court does not tend to rule on whether you "only" have the authority to do something, they're more likely to rule that a given thing is something that you don't have the authority to do. Maybe it's different when it comes to federal agencies, on that I'm ignorant. It seems more likely that the Supreme Court simply takes no issue with the new policy, rather than making a broad pronouncement about what future policy could be.
