撤销“温室气体危害认定”，引发强烈法律政治反弹，美国气候政策发生“最重大逆转”

Core Viewpoint - The Trump administration's decision to revoke the 2009 scientific finding on greenhouse gas emissions is seen as a significant rollback of climate policies, prioritizing fossil fuel interests over public health and environmental protection [1][2][3]. Group 1: Government Actions - The revocation of the "endangerment finding" is described as the largest deregulation effort in U.S. history, expected to eliminate over $1.3 trillion in regulatory costs and reduce the purchase cost of each vehicle by more than $2,400 [2]. - The action is viewed as a culmination of efforts by conservative groups and industries to weaken greenhouse gas regulations, marking a major shift in U.S. climate policy [3][6]. - The decision is anticipated to lead to a 10% increase in U.S. greenhouse gas emissions over the next 30 years, potentially resulting in 58,000 premature deaths and 37 million asthma attacks by 2055 [4]. Group 2: Industry Reactions - Some business groups support the Trump administration's actions, while others remain silent or express concerns about the negative impact on the electric vehicle manufacturing sector [5]. - The "Zero Emission Transportation Association" criticized the revocation, stating it undermines investments made by companies in the next generation of vehicles [5]. Group 3: Political Implications - The decision is expected to influence the upcoming midterm elections, with the Republican party hoping to gain votes by framing the rollback as a means to boost economic growth [6]. - The ongoing fluctuations in U.S. climate policy reflect a broader political struggle between the Republican and Democratic parties, with climate change rarely being a top concern for voters compared to economic issues [6][7].
