US Supreme Court rejects states' request to pause federal power plant emissions rule

The US Supreme Court has denied requests from 27 states to pause a new federal rule aimed at reducing emissions from coal and gas power plants. The rule, effective since July 8, requires significant cuts in greenhouse gas emissions. The Environmental Protection Agency (EPA) rule mandates that coal plants operating after 2038 and certain new gas plants reduce emissions by 90% by 2032. This includes using carbon capture technology, which the EPA claims is proven and feasible. Challengers argue the rule exceeds the EPA's authority and could effectively eliminate coal plants. However, the DC Circuit Court previously ruled that the EPA's actions are within its statutory powers.
