Last month, a federal appeals court ruled that a U.S. Environmental Protection Agency (U.S. EPA) regulation aimed at limiting planet-warming emissions from coal-fired power plants can remain in force as legal challenges continue.

The rule is the first time the federal government has restricted carbon dioxide emissions from existing coal-fired power plants. It would force future electric plants fueled by coal or natural gas to regulate up to 90% of their carbon emissions. 8/15/2024
