- Between January 20 and April 4, PM2.5 levels across the country fell by more than 18 per cent, according to the environment ministry
- But observers say that as soon as the nation’s factories and roads get back to normal, so too will the air pollution levels

China’s air quality has improved dramatically in recent weeks as a result of the widespread city lockdowns and strict travel restrictions introduced to contain the
. But experts say the blue skies could rapidly disappear as factories and roads reopen under a government stimulus plan to breathe new life into a stalled economy.
According to the Ministry of Ecology and Environment, between January 20 and April 4 the average concentration of PM2.5 – the tiny particles that pose the biggest risk to health – fell by 18.4 per cent from the same period of last year.
Meanwhile, the average number of days with good air quality – determined as when the air pollution index falls below 100 – rose by 7.5 per cent, it said.
Satellite images released by Nasa and the European Space Agency showed a dramatic drop in nitrogen dioxide emissions in major Chinese cities in the first two months of 2020, compared with a year earlier.
According to Nasa, the changes in Wuhan – the central China city at the epicentre of the initial coronavirus outbreak – were particularly striking, while nitrogen dioxide levels across the whole of eastern and central China were 10 to 30 per cent lower than normal.
The region is home to hundreds of factories, supplying everything from steel and car parts to microchips. Wuhan, which has a population of 11 million, was placed under lockdown on January 23, but those
restrictions were lifted on Wednesday

Nitrogen dioxide is produced by cars, power plants and other industrial facilities and is thought to exacerbate respiratory illnesses such as asthma.
The space agency said the decline in air pollution levels coincided with the restrictions imposed on transport and business activities.
That was consistent with official data from China’s National Development and Reform Commission, which recorded a 25 per cent fall in road freight volume and a 14 per cent decline in the consumption of oil products between January and February.

Liu Qian, a senior climate campaigner for Greenpeace based in Beijing, said the restrictions on industry and travel were the primary reasons for the improvement in air quality.
According to official data, in February, the concentrations of PM2.5, nitrogen dioxide and sulphur dioxide – a toxic gas that comes mostly from industrial burning of coal and other fossil fuels – all fell, by 27 per cent, 28 per cent and 23 per cent, respectively.
“The causes of air pollution are complicated, but the suspension of industrial activity and a drop in public transport use will have helped to reduce levels,” Liu said.
As the epicentre of the Covid-19 pandemic has shifted to the
United States and
, human and industrial activity in China is gradually picking back up, and so is air pollution.
Lauri Myllyvirta, lead analyst with the Centre for Research on Energy and Clean Air in Helsinki, said that levels of nitrogen dioxide pollution, measured both by Nasa satellites and official stations in China, started inching back up in the middle of March and had returned to normal levels by the end of the month.
That coincided with the centre’s findings – published on Carbon Brief, a British website on climate change – that coal consumption at power plants and oil refineries across China returned to their normal levels in the fourth week of March.
How the Wuhan experience could help coronavirus battle in US and Europe
Ma Jun, director of the Institute of Public & Environmental Affairs, a Beijing-based charity, said a stimulus plan to kick-start the economy would have a significant impact on air pollution.
“Once industrial production is fully resumed, so are the emission levels,” he said. “Unless another outbreak happens and triggers another lockdown, which would be terrible, the improvement achieved under the pandemic is unstable and won’t last long.”
After the 2008 financial crisis, Beijing launched a 4 trillion yuan (US$567.6 billion) stimulus package that included massive infrastructure investment, but also did huge damage to the environment. In the years that followed, air pollution rose to record highs and sparked a public backlash.
Even before the
Covid-19 outbreak, China’s economy was slowing – it grew by 6.1 per cent in 2019, its slowest for 29 years – and concerns are now growing that policymakers will go all out to revive it.
“Local governments have been under huge pressure since last year, and there are fears that environmental regulations will be sidelined [in the push to boost economic output],” Ma said.
But Beijing had the opportunity to get it right this time by investing more in green infrastructure projects rather than high-carbon projects, he said.
“A balance between economic development and environmental protection is key to achieving a green recovery, and that is what China needs.”

BEIJING (Reuters) – China will promote the sales of export products in domestic markets, as foreign trade faces unprecedented challenges due to the coronavirus pandemic, an assistant commerce minister said on Friday.
As the coronavirus spreads to almost all of China’s trading partners, the world’s second-largest economy is set to reach a grim milestone for full year growth, with the pace of expansion likely to be the slowest since the Cultural Revolution ended in 1976. And, the export sector is facing millions of job losses and factory shutdowns.
“Due to the rapid spread of the epidemic in the world, foreign demand has slumped and the biggest difficulty facing foreign trade companies is the plunge in orders,” said Ren Hongbin, the assistant minister at the Ministry of Commerce.
He said firms across the board have had their orders cancelled or delayed, and new orders are “very hard to sign”.
“The uncertainty about the pandemic has become the biggest uncertainty for foreign trade development.”
Forecasters expect China’s 2020 growth could be nearer the 2.0% mark – the slowest in over 40 years – due to the sweeping impact of the pandemic both at home and overseas. The economy grew 6.1% last year.
China’s overseas shipments fell 17.2% in January-February from the same period a year earlier, marking the steepest fall since February 2019. Imports sank 4% from a year earlier.
Among the government measures to support the sector, China is accelerating efforts to build online trade fairs and guiding exporters to work with e-commerce retailers for sales in domestic markets and coordinating with its trading partners to stabilise supply chains, said Ren.
The Canton Fair, China’s oldest and biggest trade fair due to take place online, will feature live-streaming services for participants, Li Xingqian, another commerce ministry official, told the same briefing. The fair was originally scheduled to begin on April 15, but was postponed due to the coronavirus outbreak.
China is willing to boost trade relations with other countries, including the United States, under the new circumstances, said Ren, adding that Beijing hopes to work together with Washington to promote bilateral trade.
Both countries have been engaged in a near two-year long trade war with tit-for-tat tariffs on each other’s goods, before negotiators called a truce with an interim trade deal in January.
