U.S. Sen. Lamar Alexander, R-Tenn., Wednesday co-sponsored legislation that would prohibit the Environmental Protection Agency (EPA) from regulating carbon dioxide emissions on new and existing power plants unless multiple agencies certify such regulations will not hurt jobs, the economy and electricity reliability.

Alexander also signed a letter by Sen. David Vitter, R-La., to the president calling on the administration to withdraw its proposed rule to regulate carbon dioxide emissions from existing power plants.

“Regulations on carbon from power plants will drive electricity prices up for families and businesses and drive down job growth,” said Alexander in a news release.
