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 cleaner energy.
Volkswagen AG plans 15 new-energy models
over 3-5 years, its China chief told a green car conference in Beijing on
Saturday, predicting - like the government - that Chinese 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 Ltd's chairman
told media that the Chinese automaker's electric vehicle sales 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, the finance minister
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 the incumbent president, showed electric vehicles charged
in China produce two to five times as much particulate matter and chemicals
that contribute to smog versus gas-engine cars. Hybrid vehicles fare little
better.
"International experience shows that
cleaning up the air doesn't need to rely on electric vehicles," said Los Angeles-based
An Feng, director of the Innovation Center for Energy and Transportation.
"Clean up the power plants."
China plans to convert the grid to
renewable fuel or clean-coal technology as part of efforts to cut carbon
emissions by 60 percent by 2020.
That will speed the green impact of
electric vehicles, said environmental science professor Huo Hong at the elite
Tsinghua university. But that goal will be "really difficult to
achieve."
Tsinghua's studies call into question the
wisdom of aggressively promoting vehicles which 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.
POLICY MISMATCH
To promote new-energy vehicles, the
government has offered various incentives in recent years including tax breaks,
and set targets such as having 5 million new-energy 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, for instance, 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 gas-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.
But Beijing, Tianjin and Hebei are all more
than 90 percent reliant on coal for energy, Tsinghua's research showed.
Huo and academics point out 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.
