  • A study by researchers at the University of California, Riverside’s College of Engineering – Center for Environmental Research and Technology (CE-CERT) and colleagues at the California Air Resources Board (ARB) found a relatively clear trend of increasing NOx emissions with increasing biodiesel blend level at levels of B20 and above for CARB-like/high cetane diesel fuels. The study is published in the ACS journal Environmental Science & Technology.

  • In the first major step of this effort, researchers at CE-CERT have evaluated the potential impacts of using biodiesel in diesel sold through California. Biodiesel may provide significant reductions in carbon dioxide emissions because it is produced from renewable sources, such as soybeans, that absorb carbon dioxide while growing.

  • Question: Returning from Sacramento on Insterstate 80, I often come upon heavy traffic through Berkeley. It eases after I take the turn to the Bay Bridge. Question No. 1. Why? Is there inadequate highway into Oakland? I am losing patience.

  •  Kansas, Colorado and New Mexico transportation officials have notified Amtrak that they do not have the millions of dollars the passenger rail service said is necessary to repair and maintain deteriorating tracks in western Kansas.

  • The state ran a test of its controversial greenhouse-gas market Thursday, even as it wrestles with ongoing complaints that the price of carbon could prove too costly for businesses.

  • Oakland International Airport ranked fifth in on-time performance in the state, while San Francisco International had the worst on-time record.

    We don't know definitively that age was a factor in the accident that occurred when a 100-year-old driver — 101 next week — backed his car into a South Los Angeles street, hitting 11 children and adults and seriously injuring four of them. Maybe the brakes on Preston Carter's 22-year-old Cadillac failed, as he told reporters at the scene. Or maybe he made the kind of mistake that any driver of any age might make. Police detectives are still investigating.

  • Four bills that would expand cities’ and counties’ ability to divert property taxes for local development projects have made it to the final sprint of the state legislative session, which ends today at midnight, and are now on the governor's desk.

  • Opponents of high-speed rail contend that it's a boondoggle because of its $68 billion pricetag. But a recent UC Berkeley study provides evidence that a California bullet train might be a good investment, particularly when it comes to reducing greenhouse gases and fighting climate change. The study, published recently in the journalEnvironmental Research Letters, was the result of two years of research by UC Berkeley civil and environmental engineering professor Arpad Horvath and Mikhail Chester, professor at Arizona State University's School of Sustainable Engineering and The Built Environment.
