California Air Resources Board

California surveyed applicants for the state electric-car incentive program, and will put the results online.

Last week, the very first 2015 Hyundai Tucson Fuel Cell hydrogen-powered vehicle was delivered to lessee Timothy Bush in Southern California. The event was widely covered, as the fuel-cell Tucson crossover may well be the highest-volume hydrogen vehicle on U.S. roads until Toyota and Honda start...

Exactly a year ago, Tesla Motors CEO Elon Musk presided over a flashy demonstration in which the battery pack of a Tesla Model S electric car was apparently swapped from underneath within 90 seconds and replaced with a fresh pack. The event generated a huge amount of press, and subsequent coverage...

California dominates the list of most-polluted U.S. cities, justifying its stricter environmental regulations.

It was one of the thorniest issues facing the powerful California Air Resource Board: Did the ability to swap electric-car battery packs qualify for "fast fueling" incentives meant to prod carmakers to build zero-emission vehicles that could add 300 miles of range in no more time than filling the...

As expected, the 2014 BMW i3 electric car has been awarded its "white sticker," the coveted permission to drive in High-Occupancy Vehicle lanes with only one occupant on California's crowded freeways. The range-extended version of the i3, however, has not yet appeared on the list--and there remains...

You never know what you may find if you read through public comments on government proposals. That's how we found a broad hint that the next version of the Toyota Prius Plug-In Hybrid will have a continuous all-electric range of at least 10 miles. Remember that the current car, which the EPA rates...

The 2014 BMW i3 electric car, which we drove last week, is generating intense interest among both plug-in proponents and BMW fans. Among other things, it's the first car in the world offered with an optional range-extending engine, at an increased cost of $3,850. MORE: 2014 BMW i3: First Drive Of...

You can break down car companies into three groups, depending on their electric-car activities. The leaders are Nissan, General Motors, BMW, and upstart Tesla, all of whom have developed purpose-built plug-in cars. The followers are most of the large players in the global industry, who largely...

Tesla Motors has surprised a lot of skeptics in its decade of existence. But last month's announcement of battery swapping for Model S cars traveling long distances deserves some additional context. It adds a new and quicker way for some Model S drivers to cover distances beyond the battery range...

Say "carpool lane" or "HOV Access" or "white sticker" or "green sticker," and most California commuters will begin to drool uncontrollably. The ability to drive in relatively uncrowded High-Occupancy Vehicle (HOV) lanes with just a single person in the vehicle is a privilege that Californians will...

Unless you follow green cars fairly closely--or perhaps live in California--you may not know that the Golden State now requires the sale of certain number of battery electric cars. Between 2012 and 2014, the six highest-selling carmakers in the state must sell a combined 7,500 zero-emission...

There are two kinds of electric cars on sale in the U.S. these days. The first kind--the ones you should pay attention to--are the volume electric cars. Their makers want to sell as many as they can. The second kind are the "compliance cars," built solely to meet California regulations that require...

Californians wanting to gain single-occupancy access to the state’s high-occupancy vehicle (HOV) lanes now have twice as many eligible cars to choose from when buying their next vehicle. Yesterday, Ford announced that its 2013 C-Max Energi plug-in hybrid has met the standards set out by the...

Few states in the U.S. can match California’s generosity when it comes to clean vehicle rebate programs. In fact, back in September, the California Air Resources Board and the Environmental Protection Agency awarded the state’s 10,000th Clean Vehicle Rebate to a Nissan Leaf owner from...

Most brand-new auto technologies are, at best, a breakeven proposition in their early years. Toyota is thought to have lost money on every Prius hybrid it sold for several years, until its sales rose enough to gain economies of scale. Makers of plug-in electric cars may be losing money on each one...

California's high-occupancy vehicle lanes, which emptied out last July as 85,000 hybrids lost their access, are about to start admitting more cars. This week, Chevy dealers in California are receiving their first 2012 Chevrolet Volts fitted with the right emissions gear to give drivers access to...

Earlier today,General Motors confirmed that it has restarted production of the 2012 Chevrolet Volt at its Detroit Hamtramck facility. In addition, the automaker has confirmed that it is now producing Californian-market Volts, complete with a low emissions package that enables them to qualify for...

California has always led the nation in mandating reduction of tailpipe emissions and development of low- and zero-emission vehicles. For several years now, states have had the option of adopting stricter California vehicle-emissions regulations or sticking with the national standards. Roughly a...

Daniel Yergin is one of those authors who writes major works. His Pulitzer Prize-winning The Prize is nothing less than the definitive history of the rise of the petroleum industry, and his latest, The Quest: Energy, Security, and the Remaking of the Modern World, starts where that book left off...
