On Monday, the Ministry of Ecology and Environment said that Olympics had arrived just as the transition from winter to spring created âextremely unfavorable conditionsâ across north China. Ministry officials promised to fix the situation ahead of the Opening Ceremonies on Feb. 4 and authorized local governments to take ânecessary actionâ to improve air quality.
While less severe than Beijingâs infamous âairpocalypseâ winters of a decade ago, the spiking pollution levels make outdoor exercise inadvisable just as athletes are arriving and add to fears that China will not fulfill promises of a âgreenâ and carbon-neutral Olympics.
Lauri Myllyvirta, lead analyst at the Center for Research on Energy and Clean Air, a Finland-based group, said the downturn in air quality, despite extensive government preparations, âshows how far Beijing has to go to systematically limit winter air pollution.â
âEven after all the progress in controlling emissions, the vast concentration of industry around Beijing means that when the weather is unfavorable, smog returns,â he said.
A relapse into Beijingâs hazier days during the Olympics would be especially embarrassing for a city that already went to great lengths to deliver blue skies during the 2008 Summer Games. Then, the cleanup effort required hundreds of factories to be shuttered or relocated. Thousands of home coal-burning boilers were converted to natural gas.
Air quality in the city improved by 50 percent over that summer, according to official numbers. The drastic change meant more than just a welcome respite for Beijingers, it underscored the pressing health concerns of pollution. By comparing mortality rates in Beijing that summer to other cities in China, economists estimated that a 10 percent decrease in the particulate matter known as PM10 prevented about 196,000 premature deaths per month.
In the following years, awareness of the harmful effects of air pollution on the nationâs health mounted until a documentary 2015 from a state media journalist on the topic was an instant hit â before being quickly banned. In the face of the mounting popular pressure, the government declared war on pollution.
Beijingâs air quality has improved dramatically since then. Last year, concentrations of the minuscule and more dangerous pollutant known as PM2.5 met national standards of 35 micrograms per cubic meter of air for the first time. But that level is still about seven times higher than the World Health Organizationâs recommended amounts and often soars higher in the winter months.
Even at this late hour ahead of the Olympics, the Chinese government has a range of options to rapidly improve air quality. Among those is an expansive weather modification program that uses cloud-seeding technology to increase rainfall in an attempt to flush out dirty skies.
Another method is to further reduce output from smoke-belching steel mills and coal-fired power plants. In Tangshan, the steelmaking capital of China that sits two and a half-hourâs drive west of Beijing, most factories were ordered to operate at well below full capacity from August until March.
But acting too harshly could risk of a backlash from industry after authorities had promised to minimize the economic costs of the Games. In December, the Environment Ministry was forced to deny rumors it planned to order production cuts for coal-burning industries in multiple provinces.
Then there are the upcoming New Yearâs celebrations. A ban on unauthorized fireworks in downtown Beijing is a long-standing feature of the anti-pollution campaign, but the prohibition had been only partially successful in reducing amateur pyrotechnics on the cityâs streets. This winter, restrictions have been expanded to the suburbs and backed up by a crackdown on the underground firecracker trade.
In the last three months of 2021, Beijing police confiscated 8,604 boxes of firecrackers and slapped 103 offenders with punishments ranging from a warning to criminal detention. Cash rewards of up to 20,000 yuan ($3,000) were offered for tips.
