Chevron Defies California On Carbon Emissions

Chevron Corp. (CVX) helped write the first-in-the-nation rule ordering reduced carbon emissions from cars and trucks. Its biofuels chief spoke at the ceremony where California Governor Arnold Schwarzenegger signed the executive order in 2007, the same year the oil company pledged to develop a gasoline replacement from wood.

Now Chevron is leading a lobbying and public relations campaign to undercut the California mandate aimed at curbing global warming, two years after the state started phasing it in. Research on commercially viable climate-friendly products has come to naught, stymied by the poor economics of coaxing hydrocarbons from plants’ stubborn cell walls, according to Chevron officials.

China pollution may hold silver lining for California

BEIJING — As Gov. Jerry Brown tours some of China’s economic hubs this week, he is breathing the kind of heavy, soiled air that blanketed Los Angeles decades ago.

The soot and smog that are byproducts of this country’s industrial progress are choking its people and threatening its economy. Chinese leaders are talking openly about the need to clean up the air, and to learn how from California.

Tar sands refining in Southern California needs scrutiny, say environmentalists

Oil refiners are sending greater amounts of an especially dirty crude oil product called “tar sands” to their Southern California refineries.

Now environmental groups want regulators to take a closer look

Tar sands hold a kind of semi-solid petroleum. To refine it enough for California standards takes more processing. Oil companies – including Valero, Tesoro and Conoco Phillips – say they’re bringing in more of this raw material because liquid petroleum in California is drying up.
