The Justice Department (DOJ) has opened an antitrust inquiry into 4 major automakers who recently struck a deal with California to boost emissions standards for their nationwide fleets, The Wall Street Journal reports.

Why it matters: The report, if correct, signals the opening of a new and high-stakes front in the fight between California and the White House over vehicle emissions and mileage rules.

Emissions credits are like gold for automakers

One way carmakers comply with increasing fuel economy standards — even without selling many hybrids or electric cars — is by using regulatory credits they stockpiled from previous years or purchased from competitors.

Why it matters: The standards are getting tougher now, and companies are not only drawing down their banked credits; they've stopped generating new ones, too. That could drive up their trading value, enriching some companies with credits to spare, while putting others at risk of non-compliance.
