Automakers’ latest projections for rapid growth of China’s “green” car market have added to concerns of worsening smog as the uptake of electric vehicles powered by coal-fired grids races ahead of a switch to sources of cleaner energy.
Volkswagen AG plans 15 “new-energy” models over three to five years, its China chief told a “green car” conference in Beijing on Saturday last week, predicting — like the Chinese government has — that the nation’s production of electric and plug-in hybrid vehicles would grow almost six times to 2 million annually by 2020.
At the same event, BYD Co’s chairman told reporters that the Chinese automaker’s sales of electric vehicles would double in each of the next three years.
The government has been promoting electric vehicles to cut the smog that frequently envelops Chinese cities, helping sales quadruple last year and making China the biggest market, Chinese Minister of Finance Lou Jiwei (樓繼偉) said at the conference.
Less than 1 percent of passenger cars are now “new energy,” but the pace of growth raises their potential to worsen smog.
A series of studies by Tsinghua University, whose alumni includes Chinese President Xi Jinping (習近平), showed that electric vehicles charged in China produce two to five times as much particulate matter and chemicals that contribute to smog versus gasoline cars. Hybrid vehicles fare little better.
“International experience shows that cleaning up the air doesn’t need to rely on electric vehicles,” said An Feng, director of the Los Angeles-based Innovation Center for Energy and Transportation. “Clean up the power plants.”
China plans to convert the grid to renewable fuel or clean-coal tech as part of efforts to cut carbon emissions by 60 percent by 2020.
That will speed the “green impact” of electric vehicles, Tsinghua University professor of environmental science Huo Hong said.
However, that goal will be “really difficult to achieve,” he said.
Tsinghua’s studies question the wisdom of aggressively promoting vehicles that the university said could not be considered environmentally friendly for at least a decade in many areas of China unless grid reform accelerates.
China’s industry, environment and science ministries, which devise most “new-energy” vehicle policies, did not respond to requests for comment.
BYD and Volkswagen declined to immediately comment.
To promote “new-energy” vehicles, the Chinese government has offered various incentives in recent years, including tax breaks, and set targets such as having 5 million such vehicles on the road by 2020 — more than 8 times the current number.
Authorities in some cities particularly affected by smog have gone further. Beijing and Tianjin have exempted “new-energy” vehicles from limits on the number of new cars granted license plates and exempted them from driving restrictions that other cars face on certain days of the week.
This month, the industrial Hebei Province decreed that all new residential complexes must have car-charging facilities.
In western Beijing, 62-year-old retired truck and taxi driver Zhang Zhijun bought a BYD Tang hybrid last month and plans to trade in his gasoline-engine Toyota Corolla for an electric car for short rides like taking his grandson to school.
“Right now smog is very heavy in China. This way, if everyone does their part, it will definitely cut down on pollution,” Zhang said.
However, Beijing, Tianjin and Hebei are all more than 90 percent reliant on coal for energy, Tsinghua’s research showed.
Huo and academics say that, at the very least, the proliferation of electric vehicles pushes more sources of pollution away from heavily populated urban centers.
Whatever the impact, Qin Lihong, president of startup electric automaker NextEV, said cleaning the grid would be the quickest route to clear skies.
“It’s much easier for society to make hundreds of power plants better than change the hundreds of millions of cars in thousands of cities,” he said.
Australians were downloading virtual private networks (VPNs) in droves, while one of the world’s largest porn distributors said it was blocking users from its platforms as the country yesterday rolled out sweeping online age restriction. Australia in December became the first country to impose a nationwide ban on teenagers using social media. A separate law now requires artificial intelligence (AI)-powered chatbot services to keep certain content — including pornography, extreme violence and self-harm and eating disorder material — from minors or face fines of up to A$49.5 million (US$34.6 million). The country also joined Britain, France and dozens of US states requiring
Hungarian authorities temporarily detained seven Ukrainian citizens and seized two armored cars carrying tens of millions of euros in cash across Hungary on suspicion of money laundering, officials said on Friday. The Ukrainians were released on Friday, following their detention on Thursday, but Hungarian officials held onto the cash, prompting Ukraine to accuse Hungary’s Russia-friendly government of illegally seizing the money. “We will not tolerate this state banditism,” Ukrainian Minister of Foreign Affairs Andrii Sybiha said. The seven detained Ukrainians were employees of the Ukrainian state-owned Oschadbank, who were traveling in the two armored cars that were carrying the money between Austria and
Kosovar President Vjosa Osmani on Friday after dissolving the Kosovar parliament said a snap election should be held as soon as possible to avoid another prolonged political crisis in the Balkan country at a time of global turmoil. Osmani said it is important for Kosovo to wrap up the upcoming election process and form functional institutions for political stability as the war rages in the Middle East. “Precisely because the geopolitical situation is that complex, it is important to finish this electoral process which is coming up,” she said. “It is very hard now to imagine what will happen next.” Kosovo, which declared
MORE BANS: Australia last year required sites to remove accounts held by under-16s, with a few countries pushing for similar action at an EU level and India considering its own ban Indonesia on Friday said it would ban social media access for children under 16, citing threats from online pornography, cyberbullying, online fraud and Internet addiction. “Accounts belonging to children under 16 on high-risk platforms will start to be deactivated, beginning with YouTube, TikTok, Facebook, Instagram, Threads, X, Bigo Live and Roblox,” Indonesian Minister of Communications and Digital Meutya Hafid said. “The government is stepping in so that parents no longer have to fight alone against the giants of the algorithm. Implementation will begin on March 28, 2026,” she said. The social media ban would be introduced in stages “until all platforms fulfill their
