The landscape of environmental regulation is facing a significant shift as Wisconsin Attorney General Josh Kaul and officials from 24 other states have filed a lawsuit challenging the Environmental Protection Agency’s recent actions. This legal move targets the agency’s decision to eliminate the scientific foundation for controlling emissions contributing to climate change.
Earlier this year, the Trump administration and the EPA announced the cessation of the agency’s endangerment finding. This decision affects the regulation of greenhouse gas emissions, which had been justified by a pivotal 2009 determination that identified carbon dioxide and similar gases as threats to public health and welfare, thus necessitating regulation under the Clean Air Act.
In a statement issued Thursday, Attorney General Kaul condemned the repeal as illegal. He emphasized the need for science-based decisions, stating, “Pretending that climate change is a ‘hoax’ won’t make it go away. The federal government should acknowledge what’s actually happening and make decisions based on science.” His remarks highlight the ongoing debate over climate change policy.
The authority of the EPA to regulate greenhouse gases was affirmed by a 2007 U.S. Supreme Court decision. This legal precedent supports the states’ challenge to the agency’s recent policy changes.
The potential consequences of the EPA’s repeal are significant. According to the Environmental Defense Fund, Wisconsin could face billions in fuel costs and health-related expenses through 2055. Conversely, the EPA projects over $1.3 trillion in savings from reduced costs associated with new or electric vehicles. However, a regulatory analysis suggests that overall expenses, including fuel and maintenance, could offset these savings.
Furthermore, the EPA has relaxed the vehicle greenhouse gas emission standards that were previously tightened under the Biden administration. With transportation being the largest source of greenhouse gases in the United States, this change is crucial in the broader context of emissions control.
The legal challenge has garnered support from almost 40 cities, counties, and states. Prior to this lawsuit, green and public health organizations had already filed their own lawsuits against the EPA’s repeal decision.
