    China’s smog problem explained

    Beijing, China – A thick haze has this week smothered Beijing and surrounding areas, with tens of millions of people in northern China under severe pollution warnings.


    Here’s what you need to know about the smog in northern China:


    – Just how bad is it? –


    China’s weather office has said “foggy and hazy” conditions are prevalent in the capital Beijing, the megacity of Tianjin, and parts of the provinces of Hebei, Shandong and Hubei, home to more than 100 million people in total.


    Many of Beijing’s 22 million residents donned face masks on Wednesday morning as they snaked through streets shrouded in a grey haze.


    The pollution in some areas has been classified as “severe” and has at times lowered visibility to less than 50 metres (164 feet).


    Beijing has experienced five days with “unhealthy” pollution levels in the last week, compared to just three such days in the past three weeks, air quality monitoring firm IQAir’s data showed.


    IQAir said Beijing was the third most-polluted major city on Earth on Wednesday, just ahead of Bangladesh’s capital Dhaka. Beijing’s concentrations of hazardous PM 2.5 particles were more than 20 times higher than World Health Organisation guidelines, the firm said.


    PM 2.5 particles, if inhaled, can have serious health risks, linked to premature deaths in people with heart or lung disease, as well as a host of breathing and other health issues, according to the US Environmental Protection Agency.


    – Are things getting better? –


    A decade ago, Beijing routinely choked in off-the-charts smog that stoked public health anxiety and was dubbed the “airpocalypse” by Western commentators.


    China declared “war on pollution” after winning the Winter Olympics bid in 2015, shutting down dozens of coal plants and relocating heavy industries.


    That has brought significant improvements, but air quality often remains below World Health Organization standards and severe pollution is common in China’s capital.

    In March and April, Beijing experienced six days when pollution levels were considered “very unhealthy” — meaning air quality had reached emergency levels, data from the US embassy showed.


    Beijing also experienced five days of “unhealthy” pollution levels around October and November last year. China is the world’s biggest emitter of the greenhouse gases driving climate change, such as carbon dioxide.


    A recent jump in approvals for coal-fired power plants has added to concerns that China will backtrack on its goals to peak emissions between 2026 and 2030 and become carbon-neutral by 2060.


    – What are the causes? –


    The capital’s location plays a role. Nestled between deserts to the north and dense industrial clusters to the south and east, the direction of the prevailing wind can often determine whether the city sees blue skies or dense smog.


    But the bad air is also man-made: highly-polluting heavy industry, the common use of coal burning for electricity and vehicle emissions, IQAir said. Beijing’s city government has blamed “unfavourable weather conditions” such as high humidity and unseasonably hot temperatures.


    It has said that colder weather may help dissipate the pollution.


    – What steps have been taken? –


    The second-highest air pollution alert is in place in Beijing until the end of Thursday. The alert orders businesses, builders and transport firms to cut their emissions as a matter of urgency.


    Further curbs, such as temporary bans on the use of some high-emissions vehicles, will come into force if the highest alert — already in force in parts of Hebei province — is triggered.


    Authorities have also urged residents to reduce outdoor activities and strenuous exercise during periods of high pollution.

    When I was working in China 20 years ago, they were commissioning a new coal burning plant every 6 weeks. Each one had 4 huge boilers and four 4-500 foot tall smoke stacks. The amount of coal needed to feed each of these plants is very large, and they were burning the cheap stuff.

    They have slowed the commissioning of new plants but the smoke from those coal plants was fairly major, and they fed juice to other industrial plants that had their own emissions. The smoke was so bad in the Pearl River areas I was in that I would have to put a wet towel under the hotel door to keep the smell out. Don't miss China at all.

    Like London in the good old days.

    I still remember the smell that greeted us on Liverpool St station and stayed with us until we left.

    Nice trip though.

    Indonesia has the same problem.

    Instead of closing coal fired plants, they are just moving them further away from Jakarta so that the capital receives fewer complaints about air quality!

    Western countries, having had the full benefits of the Industrial Revolution, can now look down on developing countries with a smug grin, having moved over to a different income stream!

    And should have a "no child policy" to be honest.

    Not with CO2. But leading with air pollution for lack of smoke filters in industrial production.
