New submitter Rick Schumann writes about California considering a ban on internal combustion engines: The ban on internal-combustion engine automobiles would be at least 10 years away, and it's unclear at this early stage if it would ban only sales and use of new cars, or ban existing cars as well. There's also no mention of two (or three) wheeled vehicles at this stage. The California Air Resources Board (CARB) is nevertheless considering this seriously, in order to meet its ambitious emissions reduction goals. According to state data, tailpipes generate more than one-third of all greenhouse gases, and so far only a small fraction of California's motorists drive electric vehicles. The announcement was made in an interview with Bloomberg news. "I've gotten messages from the governor asking, 'Why haven't we done something already?' The governor has certainly indicated an interest in why China can do this and not California," Mary Nichols, the chairwoman of the CARB, told Bloomberg.
