On Wednesday, the Obama administration proposed new clean car standards. The standards would require cars and light trucks in model years 2017-2025 to meet a fleet-wide average global warming pollution standard equivalent to 54.5 miles per gallon.

Environment Montana, a state based citizen funded environmental group says by 2030 the proposed standards would reduce annual global warming pollution by 280 million metric tons. In Montana alone, the proposed standards would generate annual savings of $153 million—or $368 per family. The Obama administration is expected to conduct a public comment period and hold public hearings to gauge public opinion of the new standards, before finalizing the standards next year.
