DETROIT ? Ford Motor Co. CEO Bill Ford Jr. tells says he?s ready to restart his clean revolution now that his company is no longer losing money. Ford won’t publicly commit to any hard targets, even refusing to confirm leaks from his own execs that Ford is aiming to cut in half the global-warming gases coming from its cars by 2030, which will require an 80 percent boost in gas mileage.

“My passion for the environment hasn’t waned one bit over the years,” he told Newsweek Detroit Bureau Chief Keith Naughton in the current issue. “It’s just that events overtook me when I became CEO, and the fires were raging everywhere.” Now “These are the kind of issues I’m driving personally,” he says.

Even his allies want something tangible on how he’s cleaning up his cars in the next five years-not in a quarter-century. “We’re rooting for him,” says environmental shareholder activist Mindy Lubber. “But he’s got to act sooner.”
