WASHINGTON — Congressional Republicans opened a formal assault Wednesday on the authority of the Environmental Protection Agency to regulate greenhouse gases, raising doubts about the legal, scientific and economic basis of rules proposed by the agency.
The forum was a hearing convened by the energy and power subcommittee of the House Energy and Commerce Committee to review the economic impact of pending limits on carbon dioxide and other heat-trapping gases. But much of the discussion focused on whether climate science supports the agency’s finding that greenhouse gases are a threat to human health and the environment.
