Federal rollbacks of pollution and climate regulations spark political backlash

The cluster focuses on major Trump-era rollbacks of U.S. climate and environmental rules, including the weakening of greenhouse gas regulations and the repeal of a key EPA air pollution enforcement measure. These actions are framed by the administration as victories for deregulation and economic growth. In response, more than three dozen Democratic senators have launched an inquiry into the EPA’s decisions, highlighting concerns over public health, environmental justice, and U.S. commitments to address climate change. The clash underscores a broader national debate over the balance between environmental protection and regulatory restraint.
