China is suspending the production of more than 500 car models and model versions that do not meet its fuel economy standards, several automakers confirmed Tuesday, the latest move by Beijing to reduce emissions in the world's largest auto market and take the lead in battling climate change. The suspension, effective Jan. 1, would affect both domestic carmakers and foreign joint ventures ... in China, where 28 million vehicles were produced in 2016. China has dozens of small-scale automakers - some producing just a few hundred cars a year. Cui Dongshu, the secretary general of the China Passenger Car Association, said that the ban would affect at most 1 percent of the Chinese market. But the government's decision to cite fuel economy in the deregistration of so many versions at the same time is nonetheless a signal of the government's commitment to fuel economy. The country, which for years prioritized economic growth over environmental protection ... has emerged as an unlikely bastion of climate action. "They're sending a signal to everybody," said Michael Dunne, president of ... a Hong Kong-based consultancy on China's clean car market. "This shows their emissions standards have teeth." The Chinese government has already become the world's biggest supporter of electric cars, offering automakers numerous incentives for producing so-called new energy vehicles. Those incentives are set to decrease by 2020, to be replaced by quotas for the number of clean cars automakers must sell.
