Inside Beijing 's
airpocalypse – a city made 'almost uninhabitable' by pollution
The 21 million
inhabitants of China ’s
capital appear to be engaged in a city-wide rehearsal for life on an
inhospitable planet. Only it’s not a rehearsal: the poisonous atmosphere is
already here

The scene could be straight from a
science-fiction film: a vision of everyday life, but with one jarring
difference that makes you realise you’re on another planet, or in a distant
future era.
A sports class is in full swing on the
outskirts of Beijing .
Herds of children charge after a football on an artificial pitch, criss-crossed
with colourful markings and illuminated in high definition by the glare of
bright white floodlights. It all seems normal enough – except for the fact that
this familiar playground scene is taking place beneath a gigantic inflatable
dome.
“It’s a bit of a change having to go
through an airlock on the way to class,” says Travis Washko, director of sports
at the British School
of Beijing .
“But the kids love it, and parents can now rest assured their children are
playing in a safe environment.”
The reason for the dome becomes apparent
when you step outside. A grey blanket hangs in the sky, swamping the
surroundings in a de-saturated haze and almost obscuring the buildings across
the street. A red flag hangs above the school’s main entrance to warn it’s a
no-go day: stay indoors at all costs. The airpocalypse has arrived.
Paper face masks have been common here for
a long time, but now the heavy-duty kind with purifying canister filters – of
the sort you might wear for a day of asbestos removal – are frequently seen on
the streets. On bad days, bike lanes are completely deserted, as people stay at
home or retreat to the conditioned environments of hermetically-sealed malls.
It’s as if the 21-million-strong population of the Chinese capital is engaged
in a mass city-wide rehearsal for life on an inhospitable planet. Only it’s not
a rehearsal: the poisonous atmosphere is already here.
The British
School is the latest of Beijing ’s international
colleges to go to the drastic lengths of building an artificial bubble in which
to simulate a normal environment beneath the cloak of smog. Earlier this year,
the nearby International School of Beijing lavished £3m on a pair of domes
covering an area of six tennis courts, with hospital-grade air-filtration
systems, following the lead of the Beijing
satellite of exclusive British private school Dulwich College ,
which opened its own clean-air dome last year.
“Pollution is what all the parents are
talking about,” says Nicole Washko, Travis’s wife, who also works at the school
where their two daughters go, too. “More and more ex-pat families are leaving
this country for the sake of their kids’ health. So if all the other schools
have a dome, then we’ve got to have a dome.” A non-toxic learning environment
is perhaps the least parents might expect, when they’re paying £20,000-a-year
fees.
The British School
has recently undergone a complete filtration overhaul, as if preparing for
atmospheric armageddon, with new air curtains installed above the doors and
almost 200 ceiling-mounted air purifiers put in to complement the
floor-standing kind in each classroom. Windows must remain closed, and pupils
must adhere to the strict air safety code. Reception classes stay indoors when
the air quality index (AQI) hits 180 – measured on an official scale of 500 by
various sensors across the city. For primary kids the limit is 200, while the
eldest students are allowed to brave the elements up to 250. Anything above 300
and school trips are called off. The World Health Organisation, meanwhile,
recommends a safe exposure level of 25.
“We were finding our sports fixtures were
being cancelled so often, and kids were getting cabin fever from being kept in
doors so much of the time,” says Travis Washko. “But now we have the dome, it’s
perfect weather all year round.”
The day I arrive in Beijing , the AQI hits 460, just 40 points
away from maximum doom. It’s the kind of air that seems to have a thickness to
it, like the dense fug in an airport smokers’ cubicle. It sticks in the back of
your throat, and if you blow your nose at the end of the day, it comes out
black. Peddling around the city (I am one of the only cyclists mad enough to be
on the road) is an eerie experience – not just for the desolation, but for the
strange neon glow coming from signs at the top of invisible buildings, like a
supernatural, carcinogenic version of the northern lights. The midday sun hangs
in the sky looking more like the moon, its glare filtered out by the haze.
Daily talk of the AQI has become a national
pastime amongst ex-pats and Chinese locals alike. Air-quality apps are the
staple of every smartphone. Chinese microblogs and parenting forums are
monopolised by discussions about the best air filters (sales of the top brands
have tripled over the last year alone) and chatter about holidays to “clean-air
destinations” like Fujian , Hainan and Tibet .
This year’s Beijing marathon, held on a day that exceeded
400 on the scale, saw many drop out when their face-mask filters turned a shade
of grey after just a few kilometres. Some said it felt like running through
bonfire smoke. With such hazardous conditions increasingly common, it’s not
surprising that foreign companies are now expected to pay a “hardship bonus” of
up to 20 or 30% to those willing to work in the Chinese capital.
And yet denial still persists. Many
Beijingers tend to use the word “wumai” (meaning fog), rather than “wuran”
(pollution), to describe the poor air quality – and not just because it’s the
official Newspeak of weather reports. It’s partly because, one local tells me,
“if we had to face up to how much we’re destroying the environment and our
bodies every day, it would just be too much.” A recent report by researchers in
Shanghai described Beijing ’s atmosphere as almost “uninhabitable
for human beings” – not really something you want to be reminded of every day.
When I first came to Beijing
in 2003, as a volunteer English teacher, my students told me that the city’s
air wasn’t nearly as bad as London ’s.
“We know about your ‘pea-soupers’,” they would say, conjuring images of ye olde
England shrouded in Dickensian gloom, happily ignoring the murky haze outside
their own classroom window (then more often caused by sand storms than
coal-burning power plants). Ten years later, the same former students are all
too aware of the problem.
“We never used to have days as bad as
this,” says Li Yutong, who has recently returned to Beijing
after several years studying in Australia
and working in Hong Kong . “I used to play
football outside and go running, but you just can’t do that any more. School
kids seem to get sick more often now – and they’re much fatter because they
don’t play outside.”
Our school was sited across the street from
the national Centre for Disease Control and Prevention, which proved to be an
alarming neighbour when SARS broke out and we watched the constant train of
ambulances. Now its attentions have turned to an airborne threat of a different
kind. In June, the centre released data which suggested that the average
18-year-old Beijinger will spend as much as 40% of their remaining years in
ill-health – potentially suffering from cancer, cardiovascular or respiratory
disease. Breaking the usual government silence on the issue, China ’s former
health minister, Chen Zhu, spoke out in January to reveal that between 350,000
and 500,000 people die prematurely each year here as a result of air pollution.
In response to mounting pressure, the
government has introduced a host of new laws and regulations, increasing fines
for environmental violations, and attempting to shut down high carbon-emission
factories. But there is little to suggest any of their measures are having an
effect.
“To be able to monitor these factories,
local officials are supposed to visit them in person,” says Zhang Kai, lead
campaigner on air pollution at Greenpeace East Asia .
“But there is just no capacity to do that, and no policy in place to punish the
polluting factories effectively.”
The national “airmageddon” has spawned a
host of other attempts to solve the problem, ranging from the miraculous to the
madcap. In the western city of Lanzhou, officially deemed by the World Health
Organisation to have the worst air in China, officials have proposed digging
great gullies into the surrounding mountains in the hope of trapping polluted
air in a gigantic landscape gutter, like an atmospheric ha-ha. But Lanzhou ’s poor air
quality is caused less by burning coal and car fumes than by the local penchant
for blowing up mountains with dynamite. More than 700 peaks are being levelled
to provide swathes of flat land for development, and blowing out a huge gulley
would only add to the problem.
Other solutions proposed in Beijing have a more
futuristic air. Environmental scientist Yu Shaocai has proposed fitting water
sprinklers to the tops of tall buildings, to try and “wash” the smog out of the
sky. “Water should be sprayed into the atmosphere like watering a garden,” Yu
wrote in the journal Environmental Chemistry Letters, noting that most urban
pollution hangs below 100m, so it could be caught by an artificial shower from
the city’s taller towers. An expert in “wet deposition” (how rain can clean
particles from the air), he thinks he’s got the science sorted, and the main
challenge is just to “design the specific spray system that can spray a good
raindrop size and [ensure] the most scavenging efficiencies for the air
pollution.” But his hastily Photoshopped visuals of garden sprinklers stuck on
top of skyscrapers don’t do much to inspire confidence.
In fact, wet deposition has long been
hailed as a possible solution by higher powers, with their lofty pretensions to
control the elements. China ’s
Meteorological Administration issued a paper last year which ambitiously
declared all local officials would be able to use artificial rain to clear away
smog by 2015. And as the Washington Post reported, the idea might not be so far
from reality: because of chronic water shortages, China has invested heavily in artificial
rain since the late 1950s. The country now boats a battery of 7,000
cloud-seeding artillery guns, the same number of launchers for chemical-bearing
rockets, and more than 50 planes – all manned by an army of 50,000 employees,
ready to launch full-scale warfare on the weather.
At the other end of the scale are the
initiatives that aim to affect people’s attitudes on the ground. Driven by an
effort to raise awareness of the smog problem and spur the government into
action, a host of critical art projects have been spawned. British artist Matt
Hope has designed a “breathing bicycle”, a home-made Heath Robinson-style
contraption that filters air as you pedal along and feeds it through a tube
into a fighter-pilot breathing mask. Cycling around the hutong alleys, looking
like Darth Vader being attacked by a hoover, he’s certainly attracted some
funny looks.
“It’s a provocational prototype,” Hope
says. “It’s pretty archaic, but then burning coal is pretty archaic too. It’s
an intentionally ridiculous solution to a ridiculous problem.”
Another plucky Dutch designer thinks he can
turn the pollution into a lucrative commodity. Over the past few months, Daan
Roosegaarde has been meeting with the mayor of Beijing to talk through his plan for
“electronic vacuum cleaners” to be installed in parks across the city, to suck
smog from the skies. It might sound far-fetched, but he says his working
prototype should be ready by next summer.
“I want to move away from statistics and
the usual factsheet discussion,” says Roosegaarde, talking at excitable
break-neck speed, a man on a mission. “If you create a place that’s 75% cleaner
than the rest of the city, you create a powerful incentive for people to clean
the whole city.”
His proposal, developed in partnership with
scientists at the Technological University of Delft in the Netherlands , uses buried coils of
copper to create an electrostatic field that attracts smog particles, creating
a kind of halo of clean air above it. “It’s similar to how static electricity
attracts your hair,” Roosegaarde says. “We charge the smog particles and suck
them to the ground.”
He has also developed a mobile version
which uses the same technology, but housed in a vertical totem-pole structure
that sits atop a small temple-like pavilion, akin to those found in Beijing ’s parks. It’s
here where the real alchemy will happen. “We’re going to turn dust into
diamonds,” Roosegaarde says. “We will condense a 1,000 cubic metres
of smog down into a millimetre-cube carbon crystal – which we will set like a
diamond on a ring.” When you buy a smog ring, he says, you’re effectively
donating 1,000
cubic metres of clean air to the city.
“I like the idea that you can take a
problem and turn it into something desirable,” Roosegaarde adds. “Of course
it’s not a practical solution, but I’m hoping that smog jewellery will get
people talking about the problem – and when they see these clear circles of
blue sky above the parks, they’ll demand clean air for the whole city.”
The volume of discontent has been rising
since Beijingers got a chance to see exactly what clear blue skies looked like
last month, when miraculous weather was laid on for visiting world leaders, in
town for the high-profile Apec summit. With the kind of draconian measures
unseen since the 2008 Olympics, the entire region was locked down to guarantee
clear skies for the precious week. Production in all factories within a
125-mile radius of the city was suspended, half the cars were banned from the
roads, schools were closed, and public-sector workers were given compulsory
holidays. No weddings were registered, no passports issued, no taxes paid, no
fresh products delivered, and no banks open. Bodies went uncremated and burials
were partly suspended.
The result? A climatic Potemkin facade of
perfect blue skies – which soon became an internet meme, coining the term “Apec
blue”.
“It’s not sky blue or ocean blue. It’s not
Prussian blue or Tiffany blue,” wrote one user of the microblogging site,
Weibo. “A few years ago it was Olympic blue, and now it’s Apec blue.” It
quickly came to mean something of fleeting, artificial beauty, probably too
good to be true. “He’s not really into you,” went one recurring online saying.
“It’s just an Apec blue.”
Returning to Beijing during the Apec week was like
arriving in a completely different city. What had been a ghostly world of
streets that disappeared if more than a block away, became a wide-open place of
grand avenues terminating at distant mountains, visible for the first time.
And back at the British School ,
the smog dome was empty. Pupils were enjoying a rare outdoor lesson beneath a
different kind of artificial roof – the crystal clear canopy of Apec blue.
