美国政府撤销气候变化危害认定引多方批评

Core Viewpoint - The Trump administration announced the revocation of a 2009 EPA report that recognized the health risks of greenhouse gas emissions, which has drawn criticism from various stakeholders, including former President Obama and industry associations [1][2]. Group 1: Regulatory Changes - The Trump administration claims this is the largest single revocation of such regulations in U.S. history, stating that previous policies harmed the automotive industry and increased prices significantly [1]. - The EPA estimates that this action will eliminate over $1.3 trillion in regulatory costs and reduce the purchase cost of each vehicle by more than $2,400 [1]. Group 2: Health and Environmental Impact - The 2009 EPA report identified six greenhouse gases, including carbon dioxide, as potential threats to public health and welfare, providing a legal basis for regulating emissions under the Clean Air Act [1]. - The revocation is expected to weaken the regulatory foundation for controlling vehicle and power plant emissions, potentially making the U.S. "less safe and less healthy" and undermining climate change mitigation efforts [2]. Group 3: Legal and Institutional Reactions - Organizations such as the American Lung Association and the American Public Health Association have announced plans to challenge this "illegal revocation" [2]. - Analysts anticipate that the EPA will face legal challenges regarding this decision, indicating a contentious regulatory environment ahead [2].
