（华盛顿1日综合电）美国最高法院6月30日裁定，美国环境保护局（EPA）不能对发电厂的二氧化碳排放进行广泛设限，这预料将阻碍总统拜登的政府抗击气候变化的努力。
美国总统拜登批评，此裁决是让国家倒退的毁灭性决定，同时称当局仍将依照联邦法律，通过其他方法继续应对气候变化。
此案源于环境保护局于2015年敲定的清洁电力计划，该计划实施了时任总统奥巴马的一项指令，即利用《清洁空气法》的一项辅助条款，通过强制要求现有的煤炭和天然气发电厂减少排放，来应对气候变化。
以保守派占多数的最高法院当天以6比3的投票结果裁定，《清洁空气法》并没有赋予美国环境保护署广泛的授权来监管发电厂的温室气体排放。这些气体排放被认为是造成全球变暖的原因之一。
