US environmental regulators deny challenges to new power plant emissions rules

The US environmental regulators have rejected requests to reconsider new rules for greenhouse gas emissions from power plants. This means the stricter standards for new and existing fossil fuel-fired electricity generators will move forward as planned.

The new rules require power plants to capture carbon emissions or switch to cleaner fuels. This decision means that power companies cannot easily delay or avoid these requirements. It forces them to invest in carbon capture technology or transition away from fossil fuels, which will reshape the electricity generation landscape over the next decade.
