The vehicles are produced by a wide range of automakers, including Mercedes-Benz, Audi, Chevrolet, and a number of Chinese brands.

The latest move is part of China’s effort to curb pollution in the country and clean up smog around its largest cities, reports Chinese state news outlet Xinhua.

Since the 2008 Summer Olympics, Beijing has been on the minds of the international community due to its high levels of air pollution, rivalling that of Los Angeles before the United States implemented the Clean Air Act in 1970. More recently, complaints about air quality from residents in Beijing and other Chinese cities who are concerned about their health have caught the attention of regulators in the country.

As the world’s largest polluter and also the world’s largest automotive market (it has been the case since 2009), China’s latest move likely won’t make a massive dent in air pollution, but it’s a drastic step in line with how China plans to tackle pollution for years to come.

Like in many other juristicions around the world, China incentivizes the purchase of plug-in hybrid and electric vehicles in an effort to clean up the air. Other countries, such as Norway and the United Kingdom, plan to phase out the sale of fossil-fuel vehicles completely between 2025 and 2040.

While China aims to ban the sale of all fossil-fuel vehicles in the country entirely, it has yet to announce a date for the commitment.
