California to phase out diesel trucks with EPA approval.

The US Environmental Protection Agency has approved California's plan to phase out diesel-powered trucks, allowing the state to require truck manufacturers to sell an increasing number of zero-emission trucks over the next couple of decades. The rule applies to a wide range of trucks including box trucks, semitrailers and even large passenger pick-ups. The transportation sector accounts for nearly 40% of California’s greenhouse gas emissions. The new truck standards are aimed at companies that make trucks and those that own large quantities of them.
