That's no excuse, however, for getting the basics wrong. DON'T MISS: Hey, media, get it straight: "electrified" is...

Pruitt’s EPA emission rollback reasoning may well fail in court

EPA administrator Scott Pruitt  [photo from 2014]Despite the sturm und drang around the announcement by embattled EPA chief Scott Pruitt that he will relax emission limits for 2022 through 2025 vehicles, not much will happen immediately.

Today's cars emit less than 1 percent of the three "criteria" pollutants that came out of their tailpipes half a century ago.

Rome joins European ban-diesel bandwagon after German court ruling

Chrome exhaust pipeFirst Paris, then a pair of German cities, and now the Eternal City.
