Trump administration repeals key climate finding, removing legal basis for EPA regulations

The Trump administration has formally repealed a scientific finding from the Obama era that declared greenhouse gases a danger to public health. This finding was the legal foundation that allowed the Environmental Protection Agency to regulate carbon emissions from vehicles and power plants.

With this action, the administration has removed the EPA's authority to set climate pollution rules, which one official called the 'single largest deregulatory action' in history. The move is expected to trigger legal challenges from environmental groups and states that support climate regulations.
