California mandates 100-percent zero-emission bus fleet

December 14, 2018

California moved Friday to eliminate fossil fuels from its fleet of 12,000 transit buses, enacting a first-in-the-nation mandate that will vastly increase the number of electric buses on the road.

The California Air Resources Board voted to require that all new buses be carbon-free by 2029. Environmental advocates project that the last greenhouse-gas-emitting buses will phase out by 2040.

While clean buses cost more than the diesel and natural gas vehicles they'll replace, advocates of the mandate say they have lower maintenance and . Supporters hope creating demand for thousands of clean buses will bring down the price of those buses and eventually other heavy-duty vehicles like trucks.

California has 153 zero-emission buses on the road today with hundreds more on order. Most of them are electric, though technology also exists for buses powered by hydrogen fuel cells.

"Every state could do a strategy like this," said Adrian Martinez, an attorney for Earthjustice, an environmental legal group that supports the rule. "This is something that California did first because we have major air quality and pollution problems, but this is something other could pursue.

Existing state and federal subsidies are available to help transit agencies absorb some of the higher costs of carbon-free buses, along with money from the state's settlement with Volkswagen over the German automaker's emission-cheating software.

In approving the mandate, air board members cited both a reduction in and improved air-quality along heavily trafficked transit corridors in smog-polluted cities.

The transportation sector accounts for 40 percent of California's greenhouse gases, and those emissions are rising even as electrical emissions have fallen substantially.

California needs to drastically transportation emissions to meet its aggressive climate-change goals.

If the electricity that charges the bus's batteries is generated by nuclear or hydro then it would indeed be emission free. But California is busy tearing down its dams so the salmon can once again spawn in mountain streams and has shutdown all but one nuclear generating facility. Thus the electricity that charges the buses will be generated by fossil fuels and all that the extra expenditure for electric buses does is change and centralize the location at which the fossil fuels are burnt. The proposition that electric vehicles are cheaper depends entirely upon the lifetime of the batteries, which is not well documented. Moreover the entire reason to avoid fossil fuels, namely global warming, remains an unproven theory based upon models none of which can manage accurate prodictions. So it seems that once again California makes the politically correct, but wrong choice.

insanity. SF had a mechanical trolley and electric wire powered light rail. exclusively battery powered busses are totally uneconomical because charging takes too long any way you cut it and battery swapping does not work.

nothing wrong with having a rail/wire powered electrical system ,but why mandate building busses that are inherently inefficient and must spend a lot of time not in use, charging in massive parking lots (themselves an environmental disaster. hydrogen is a non-starter. just ask elon musk if you don't believe in common sense. which most envirowhakjobs don't. they just believe the advertising. if you relied on them, we'd be on oil and coal forever. it is the inventors engineers and sensible planners that actually improve upon systems rather than build things to fail, they build to SCALE.

california is in self destruct mode due to peak corruption and stupidity and too much weed. there's nothing environmentally friendly about failure smoke and stupidity.

Poetic justice.

California currently gets about 1/3 of it's electricity from renewables - so your assertion is only partially correct. The scales are tipping in favor of renewables - and California has just passed a bill to require 100% renewables by 2045. One step at a time the transitioning is happening. See you in the rear view mirror...
