A bill introduced Thursday in the House of Representatives would grant California the right to regulate greenhouse-gas emissions from vehicles, and pave the way for 12 other states to do the same. The U.S. EPA’s decision to keep California from regulating car GHG emissions “defied the science, defied the states, and defied common sense,” said bill cosponsor Peter Welch (D-Vt.). Similar legislation has been introduced in the Senate.
