- World’s largest coal consumer shows little sign of ending its dependency even though it is also the biggest market for renewable energy sources
- UN climate summit is meeting to discuss ways to limit future warming, but hopes are fading that China will commit to further curbs on emissions

As world leaders gather in Spain to discuss how to slow the warming of the planet, the spotlight has fallen on China – the top emitter of greenhouse gases.
China burns about half the coal used globally each year. Between 2000 and 2018, its annual carbon emissions nearly tripled, and it now accounts for about 30 per cent of the world’s total.
Yet it is also the leading market for solar panels, wind turbines and electric vehicles, and it manufactures about two-thirds of solar cells installed worldwide.
“We are witnessing many contradictions in China’s energy development,” said Kevin Tu, a Beijing-based fellow with the Centre on Global Energy Policy at Columbia University. “It’s the largest coal market and the largest clean energy market in the world.”
That apparent paradox is possible because of the sheer scale of China’s energy demands.

But as China’s economy slows to the lowest level in a quarter century – around 6 per cent growth, according to government statistics – policymakers are doubling down on support for coal and other heavy industries, the traditional backbones of China’s energy system and economy. At the same time, the country is reducing subsidies for renewable energy.
At the annual United Nations climate summit, this year in Madrid, government representatives will put the finishing touches on implementing the 2015 Paris Agreement, which set a goal to limit future warming to 1.5 to 2 degrees Celsius above pre-industrial levels.
Nations may decide for themselves how to achieve it.
China had previously committed to shifting its energy mix to 20 per cent renewables, including nuclear and hydroelectric energy.
Climate experts generally agree that the initial targets pledged in Paris will not be enough to reach the goal, and next year nations are required to articulate more ambitious targets.
Hopes that China would offer to do much more are fading.
Recent media reports and satellite images suggest that China is building or planning to complete new coal power plants with total capacity of 148 gigawatts – nearly equal to the entire coal-power capacity of the European Union within the next few years, according to an analysis by Global Energy Monitor, a San Francisco-based non-profit.

Meanwhile, investment in China’s renewable energy dropped almost 40 per cent in the first half of 2019 compared with the same period last year, according to Bloomberg New Energy Finance, a research organisation. The government slashed subsidies for solar energy.
Last week in Beijing, China’s vice-minister of ecology and environment told reporters that non-fossil-fuel sources already account for 14.3 per cent of the country’s energy mix. He did not indicate that China would embrace more stringent targets soon.
“We are still faced with challenges of developing our economy, improving people’s livelihood,” Zhao Yingmin said.
As a fast-growing economy, it was always inevitable that China’s energy demands would climb steeply. The only question was whether the country could power a sufficiently large portion of its economy with renewables to curb emissions growth.
Many observers took hope from a brief dip in China’s carbon emissions between 2014 and 2016. Today the country’s renewed focus on coal comes as a disappointment.
“Now there’s a sense that rather than being a leader, China is the one that is out of step,” said Lauri Myllyvirta, lead analyst at the Centre for Research on Energy and Clean Air in Helsinki.
He notes that several developed countries – including Germany, South Korea and the United States – are rapidly reducing their reliance on coal power.
After climbing sharply for two decades, China’s emissions stalled around 2013 and then declined slightly in 2015 and 2016, according to Global Carbon Budget, which tracks emissions worldwide.
This dip came as Chinese leaders declared a “war on pollution” and suspended the construction of dozens of planned coal power plants, including some in Shanxi.

At the same time, the government required many existing coal operators to install new equipment in chimneys to remove sulphur dioxide, nitrous oxide and other hazardous substances. About 80 per cent of coal plants now have scrubbers, said Alvin Lin, Beijing-based China climate and energy policy director for the Natural Resources Defence Council, a non-profit.
As a result, the air quality in many Chinese cities, including Beijing, improved significantly between 2013 and 2017. Residents long accustomed to wearing face masks and running home air-filter machines enjoyed a reprieve of more “blue sky days,” as low-pollution days are known in China.
In the past three years, China’s carbon emissions have begun to rise again, according to Global Carbon Budget.
The coming winter in Beijing may see a return of prolonged smog, as authorities loosen environmental controls on heavy industry – in part to compensate for other slowing sectors in the economy.

Permits for new coal plants proliferated after regulatory authority was briefly devolved from Beijing to provincial governments, which see construction projects and coal operations as boosts to local economies and tax bases, said Ted Nace, executive director of Global Energy Monitor.
“It’s as though a boa constrictor swallowed a giraffe, and now we’re watching that bulge move through the system,” said Nace. In China, it takes about three years to build a coal plant.
The world has already warmed by 1 degree Celsius. All scenarios envisioned by the Intergovernmental Panel on Climate Change for holding planetary warming to around 1.5 degrees Celsius involve steep worldwide reductions in coal-power generation.
In that effort, other countries rely on Chinese manufacturing to hold down prices on solar panels. wind turbines and lithium-ion batteries.
“China has a really mixed record. On the one hand, it’s seen rapidly rising emissions over the past two decades,” said Jonas Nahm, an energy expert at Johns Hopkins University.
“On the other hand, it’s shown it’s able to innovate around manufacturing – and make new energy technologies available at scale, faster and cheaper.”

- Doctor who helped 13-year-old girl recover says demands on her to do well at school induced condition
- Weibo poll reveals that 68 per cent of participants had hair loss in school

When the 13-year-old girl walked into the hospital in southern China around eight months ago, she was almost completely bald, and her eyebrows and eyelashes had gone.
“The patient came with a hat on and did not look very confident,” Shi Ge, a dermatologist at the Sixth Affiliated Hospital of Sun Yat-sen University in Guangzhou, told the Pear Video news portal.
The girl had done well in primary school but her grades dropped in middle school, Shi said.
Under parental pressure to do well, the girl pushed herself harder, but the stress resulted in severe hair loss.
With time and medical treatment, the teen’s hair grew back but her story left a lasting impression, raising awareness of the increasing number of young people in China seeking treatment for stress-induced hair loss, according to Chinese media reports.
Jia Lijun, a doctor at Shenzhen Traditional Chinese Medicine Hospital, told state-run Xinhua News Agency in May that aside from genetics, factors such as stress in work, study and life would result in endocrine imbalances which affected the cycle of hair growth.
And in January, a survey of 1,900 people by China Youth Daily found that 64.1 per cent of people aged between 18 and 35 said they had hair loss resulting from long and irregular working hours, insomnia, and mental stress.
Hits and myths: stress and hair loss
Shi said that an increasing number of young people had come to her for treatment of hair loss in recent years, and those working in information technology and white-collar jobs were the two biggest groups.
“They usually could not sleep well at night due to high pressure or had an irregular diet because of frequent business trips,” Shi said.
A Weibo poll on Wednesday revealed that 68 per cent out of 47,000 respondents said they had had serious hair loss when they were in school. About 22 per cent said they noticed after starting their careers, while only 5 per cent said it happened after they entered middle age.

Research published in 2017 by AliHealth, the health and medical unit of the Alibaba Group, found that 36.1 per cent of Chinese people born in the 1990s had hair loss, compared to the 38.5 per cent born in the 1980s. Alibaba is the parent company of the South China Morning Post.
The teenager’s experience sparked a heated discussion on Weibo, with users recounting similar cases and some voicing their panic.
“My niece’s hair was gone while she was in high school and has not recovered, even after she graduated from university. This makes her feel more and more inferior,” one user said.

Another said: “I lost a small portion of my hair during the high school entrance exam, but that is already scary enough for a girl in her adolescence.”
“I had to quit my job and seek treatment,” said a third, who adding that he also suffered from very serious hair loss a few months ago because of high pressure.
