The US Environmental Protection Agency is eliminating most Biden-era limits on emissions from coal and gas power plants. The agency says the changes will save $310 billion and lower energy prices. Environmental organisations say the move will harm public health and accelerate climate change. Legal challenges are expected immediately.
What rules is the EPA removing?
The Environmental Protection Agency announced it will eliminate the majority of greenhouse gas regulations for power plants that were introduced during the Biden administration. These rules set standards for carbon dioxide output from coal and natural gas facilities. The EPA determined that the previous requirements exceeded the agency's legal authority and relied on control technologies that had not been adequately demonstrated. Officials added that the regulations effectively forced some plants to close rather than allowing them to operate under achievable standards. The agency is also moving to remove all remaining greenhouse gas rules that apply to the power sector. The proposals, first put forward last year, will now go through a public comment period before final implementation.
Why does the EPA say the changes are needed?
EPA Administrator Lee Zeldin stated that American power plants produce energy more cleanly than those in other countries and should not face unfair restrictions. He said the new approach will ensure reliable and affordable energy supplies while lowering costs for transportation, heating, farming and manufacturing. The agency estimates the regulatory rollback will deliver $310 billion in savings. The EPA also argued that any public health harms linked to the power sector are too uncertain and remote to justify the previous standards. Zeldin confirmed that separate protections against hazardous air pollutants will stay in place to protect human health. The agency said the reality is that America produces energy better and cleaner than anywhere else in the world, and our power plants should not be unfairly targeted.
What did the Biden-era rules require?
The earlier regulations sought large cuts in carbon emissions from power plants, vehicles and industrial sites. Estimates at the time indicated the measures would prevent roughly 4,500 premature deaths each year. The power sector currently accounts for about one quarter of total US greenhouse gas emissions, or approximately 1.5 billion tonnes of carbon dioxide equivalent annually. US power sector emissions have declined over the past two decades, although a small increase occurred last year as coal use fluctuated. The Biden rules were part of a broader effort to reduce the country's contribution to global climate change. The EPA said the regulations required control technologies that are not adequately demonstrated, effectively forcing plants to retire rather than setting standards they could actually meet.
How have environmental groups and experts reacted?
Environmental organisations described the decision as a major setback. Nathaniel Keohane, president of the Center for Climate and Energy Solutions, said the EPA had ignored sound science and economics and failed in its duty to protect public health. Groups warned that the rollback would increase health costs for Americans and speed up planetary warming. The United Nations has identified fossil fuels as the largest driver of global climate change. The US remains the second-largest emitter of greenhouse gases after China. The power sector makes up about a quarter of US emissions, at roughly 1.5 billion tonnes of carbon dioxide-equivalent each year, according to the latest available estimates.
What legal and political background matters?
The EPA's action is expected to face immediate court challenges. In 2022 the Supreme Court limited the agency's ability to regulate emissions across entire states after states and coal companies argued the economic costs were too high. In February the current administration reversed an Obama-era finding that greenhouse gases endanger public health, a step already contested by several states and local governments. President Trump has repeatedly called for greater use of coal and criticised renewable energy sources. Researchers note that falling costs for solar and other clean technologies may limit any large-scale return to coal. The precise consequences of today's announcement for US emissions and global climate change are uncertain.
Frequently asked questions
Will the changes affect all power plants?
The EPA is targeting greenhouse gas standards for coal and gas facilities. Protections against hazardous air pollutants remain unchanged.
How much money will the rollback save?
The agency projects savings of $310 billion from removing the majority of the Biden-era climate rules.
Are legal challenges certain?
Environmental groups and some states have already signalled they will sue to block the new policy.
What happens to emissions trends?
US power sector emissions have fallen for two decades with a slight rise last year. The long-term effect of the new policy remains uncertain.
Does the EPA still regulate air pollution?
Rules covering hazardous air pollutants stay in force to protect public health.
Key takeaways
- The EPA is ending most Biden-era limits on power plant carbon emissions.
- The agency estimates $310 billion in savings and lower energy prices.
- Environmental groups warn of increased health risks and faster climate change.
- The US power sector emits about 1.5 billion tonnes of carbon dioxide equivalent yearly.
- Immediate legal challenges are expected from states and advocacy organisations.
The policy reversal continues the current administration's broader effort to reduce federal climate regulations. Outcomes for future emissions levels will depend on market forces, technology costs and ongoing court cases. [TO VERIFY: precise long-term emissions impact after rollback]
