The state of California in the U.S. won’t have any diesel-powered buses at work within a decade.

Plagued by air pollution problems, California regulators have voted to take all diesel-powered buses off the state’s roads by 2029.

In their place will be zero emissions alternatives – fuel cell powered buses and fully-electric buses.

Nearly 40 million people live in California with the move expected to be a significant boon for the nation’s electric bus manufacturers such as Proterra and Lightning Systems.

It could also have flow-on effects for traditional manufacturers too.

The California Air Resources Board (CARB) tell us the move will help reduce a large proportion of the emissions and smog-forming pollutants that contribute to the state’s air quality problems.

They say it will be the equivalent of taking four million cars off the road.

“This initiative will help modernize heavy-duty truck engines, improving their efficiency and providing cleaner air for all Americans,” – acting EPA Administrator Andrew Wheeler.

“We are under no regulatory or court-ordered requirements to launch this initiative, we are doing it because it’s good for the environment.”

And there could be similar action on the horizon for trucks in the state.

Air Resources Board spokesman Stanley Young saying nitrogen oxide pollution from heavy-duty trucks “is a huge problem both as a precursor to ozone and fine particles, and as a greenhouse gas.

“And the total emissions from this source are growing.”
