Rules aimed at limiting greenhouse gas emissions from coal and gas power plants are being repealed, the US Environmental Protection Agency (EPA) has announced. The change would overturn a rule brought in under the Biden administration in 2024 requiring power plants to use carbon sequestration equipment to control pollution. The announcement came during a meeting of energy ministers on "energy abundance" at the G20 summit in Houston, Texas. In a statement, the EPA said that scrapping the majority of climate rules from President Joe Biden's era would save $310 billion and reduce energy costs. The EPA also stated that it found Biden-era limits on power plant emissions had "exceeded the agency's authority," and it will work to prevent future administrations from doing the same. According to the agency, any potential public health harms caused by the emissions are "too uncertain, conjectural, remote, and convoluted" to be specifically linked to the power sector. Speaking to reporters, EPA Administrator Lee Zeldin said safeguards against "hazardous air pollutants" will remain in place to protect human health. Environmental groups have warned that the change will come at a huge cost to Americans' health and the planet, and the move is likely to face legal challenges.
