美国环保署于9月14日宣布废除2024年碳污染标准，取消了对燃煤和燃气电厂的大部分碳排放限制1。该标准原本规定现有煤电厂和新建天然气电厂必须在2039年前捕获90%的碳排放或关闭1。
根据拜登政府的评估，这一原有标准预计可在2047年前减少139亿吨碳污染，并能在2035年单年防止1200人死亡和36万人哮喘发作1。环保署声称撤销该标准将为企业节省3.7亿美元的监管成本1，但未公开相应的公共卫生成本代价。环保署在2025年撤销了其2009年关于温室气体危害公共卫生的认定，并提议删除对电厂的所有剩余温室气体排放要求1。
The U.S. Environmental Protection Agency announced on September 14 that it is rescinding the 2024 carbon pollution standards, effectively eliminating most emissions restrictions on coal-fired and natural gas power plants.1 The revoked standard had previously mandated that existing coal plants and newly constructed natural gas facilities capture 90 percent of their carbon emissions or shut down by 2039.1
The Biden administration's original standard was projected to reduce 139 billion tons of carbon pollution through 2047 and prevent 1,200 deaths annually by 2035, along with preventing 360,000 asthma attacks in that same year.1 The EPA claimed the revocation would save businesses 3.7 billion dollars in regulatory costs, though the agency did not disclose the corresponding public health expenses.1 Additionally, the EPA rescinded its 2009 determination that greenhouse gases endanger public health and is proposing the removal of all remaining greenhouse gas emission requirements for power plants.1
