The Obama administration has asked the Supreme Court to block the House from advancing a climate bill that would require the Environmental Protection Agency to protect the environment in any case where a state court has ruled that carbon dioxide emissions have caused a health or safety hazard, according to court filings.
The lawsuit by environmental groups is the latest development in a long-running fight over how the U.N. talks about climate change.
The EPA said in a statement that the Supreme the court’s decision would “create uncertainty about the lawfulness of EPA regulation of greenhouse gas emissions from power plants.”
The Trump administration has not responded to a request for comment.
The Environmental Protection Act is a landmark climate legislation passed by Congress in 1997.
It required the EPA to set emissions limits for power plants and other large sources of greenhouse gases and mandated the agency to regulate those emissions.
