The Japan Times - California says new cars must be zero emission by 2035

The widely touted move has been hailed by environmentalists, who hope it will prod other parts of the United States to quicken the adoption of electric vehicles.

The rules, announced by the state's air resources board, demand an ever-increasing percentage of new cars sold to California's 40 million inhabitants produce no tailpipe pollutants, until their total ban in 13 years' time.

"The timeline is ambitious but achievable: by the time a child born this year is ready to enter middle school, only zero-emission vehicles or a limited number of plug-in hybrids (PHEVs) will be offered for sale new in California," the California Air Resources Board said in a statement.

The board, which was tasked with finding a way to implement Governor Gavin Newsom's order to transition the state's automotive sector, said the environmental and health benefits would be significant.

"By 2037, the regulation delivers a 25 percent reduction in smog-causing pollution from light-duty vehicles.

"This benefits all Californians but especially the state's most environmentally and economically burdened communities along freeways and other heavily traveled thoroughfares.

"From 2026 through 2040 the regulation will result in cumulative avoided health impacts... including 1,290 fewer cardiopulmonary deaths, 460 fewer hospital admissions for cardiovascular or respiratory illness, and 650 fewer emergency room visits for asthma."

California is the biggest auto market in the United States, one that manufacturers cannot afford to ignore.

That means rules imposed in California impact production plans across the country, as well as further afield, giving the state outsize influence in effectively setting national standards.

Thursday's ruling comes on the heels of a climate law signed last week by US President Joe Biden, which sets aside hundreds of millions of dollars in incentives for clean energy programs.

Biden and his Democratic Party are rushing to make up climate policy ground they feel was lost under former president Donald Trump, who yanked the United States out of the Paris Climate Accord and reversed what many environmentalists viewed as already-weak progress in reducing the fossil fuel emissions that drive global warming.

Newsom, a leading light in the Democratic Party, who is rumored to have presidential ambitions, welcomed the ruling.

- 'Groundbreaking' roadmap -

"California now has a groundbreaking, world-leading... roadmap to reducing dangerous carbon emissions and moving away from fossil fuels," he said.

The reduction in the number of petrol and diesel-powered cars on the roads is equivalent to "915 million oil barrels' worth of emissions that won't pollute our communities."

"With the historic $10 billion we're investing to accelerate the transition... we're making it easier and cheaper for all Californians to purchase electric cars."

In recent years jurisdictions around the world, notably in Europe, have set their sights on the polluting automobile sector.

Norway is aiming to have all new cars produce zero tailpipe emissions by 2025.

The UK, Singapore and Israel are eyeing 2030, while the European Union wants to end the sale of new petrol and diesel cars by 2035.

Human-caused global warming has already raised average temperatures around the planet, affecting weather patterns and worsening natural hazards like wildfires and storms.

Scientists say dramatic action is required to limit the damage, and point to curbing emissions from fossil fuels as key to the battle.
