China’s air pollution problem

Beijing’s air quality has improved significantly since the start of the “war on pollution” seven years ago, according to official figures. In 2019, the capital’s average concentration of PM2.5 – the most harmful small particles and a key indicator of air pollution – fell to their lowest levels since its air quality monitoring network started operating in 2013. The 2019 average concentration of 42 micrograms per cubic meter was 53% lower than the 2013 figure of 89.5, according to the municipal ecology and environment bureau. The average concentration of PM10 particles and nitrogen dioxide were 68 and 37 micrograms per cubic meter, both in line with national targets. Although some pollution l

China’s war on pollution caused air pollution in major cities to shift to less developed regions and led to an overall increase in emissions, a new study has found. Researchers said that while toughened emission rules in urban areas had brought fresher air to the Chinese capital region, air pollution in the rest of China had worsened. From 2012 to 2017, the Beijing-Tianjin-Hebei urban region recorded a 34% decrease in hazardous particles known as PM2.5. But the provinces surrounding the area saw an average increase of 5% in the fine particulate matter. Overall, China except the capital region saw a 2.5% increase in PM2.5, the study says. The additional pollution represents an increase of 1.

122nd: Beijing’s ranking among the world’s most polluted cities. That’s according to a report on global air quality in 2018 by AirVisual, a website tracking air pollution levels in more than 3,000 cities. Beijing’s ranking is surprisingly low given its notoriously dirty air, which has made locals’ lives miserable and turned away foreign businesses. Across China, average concentrations of the hazardous particulate matter known as PM2.5 fell 11% in 2018 from 2017, according to the report, which is co-produced by Greenpeace. There’s no way to tell whether Beijing’s ranking went up or down, because this is the first such global report produced by the pollution tracker. But there are signs that

The cutting-edge image of Chinese electric car builder Nio was blunted a little after a test drive of one of its smart cars ground to a halt on one of Beijing’s most prestigious addresses, leaving the driver and a Nio rep stuck inside until the vehicle completed a software update. Nio, which markets itself as a challenger to Tesla, confirmed the incident on its Weibo account on Tuesday, claiming the driver “accidentally made a series of operations that activated the system update” during a traffic jam on Changan Avenue. The car “went dark to start an update that lasted more than an hour,” according to a message posted by the Nio employee on social media. The 2.4 mile-long Changan Avenue, wh

This winter has been an especially cold one for Nie Hongwang. In previous years, the 50-year-old villager would stockpile three or four tons of coal to use to heat the family home over the harshest winter months. But that all changed in when his rudimentary central heating system was ripped out and replaced with an environmentally friendly natural gas-powered one, under a government initiative designed to reduce air pollution. While the idea might have worked on paper, for Nie and his fellow villagers in Baoding, in the northern Chinese province of Hebei, the switch has caused nothing but problems. The high cost and unstable supply of the clean fuel have left them freezing in their own homes

It’s 9pm when the first buses start arriving at the Shanghai Bashi Public Transportation depot. In the coming two hours, as they finish service around the city’s Baoshan district, almost 300 drivers will bring their vehicles in to be cleaned, maintained and parked for the night. The queue to enter the security gate grows, but the employee in charge of the gas pumps has little to do. He battles boredom with his phone while buses pass by. His future employment prospects look bleaker still. Two hundred and forty of the buses here at the depot are fully electric. It seems likely that, next year, no combustion engines will enter the premises at all. In an effort to curb pollution and noise, China

60.4%: how much of China’s total energy consumption is met by coal. Despite China’s massive investment in cleaner energy sources, such as solar power, the country remains heavily reliant on coal.  China’s air pollution is caused in no small part by coal burning, and the occasional smog that blankets cities is a reminder of that. Dirty air in China is responsible for more than 1 million premature deaths each year, according to a study by the Chinese University of Hong Kong. As a portion of total energy consumption, coal usage in 2017 fell 1.6 percentage points from 2016 to 60.4%, according to the National Bureau of Statistics of China. Cleaner energy, including natural gas and renewables, ro

China’s troubles with air pollution are well known. In the capital of Beijing, a protective face mask is an essential part of the wardrobe.  But air pollution in China is responsible for more than just an inconvenient commute. Pollution from smog-inducing ozone and fine particles may be causing 1.1 million premature deaths and 22 million tons of lost crops each year. A new study by the Chinese University of Hong Kong has tallied up the costs of air pollution attributed to the impact on public health and reduced crop yields. The combined result is the equivalent of shaving an estimated 267 billion yuan ($38 billion) off the Chinese economy annually, researchers said. “This is a fairly large

Where does China stand on climate change? We know China is the biggest emitter of greenhouse gases globally. We know that a lot of that comes from factories that make steel, electronics and clothes for the rest of the world. We know that even after Donald Trump walked out of the historic Paris climate change agreement last year, China is still willing to stay in the game. What else do we need to know? Starting from Tuesday, we’re partnering with COAL+ICE, an exhibition in San Francisco that runs from September 4-23, interrogating the impact that fossil fuels have on climate change across the globe. For our part, we’re running a two-week series about the impact that global warming is having o

This tube-like device is able to cook your breakfast — using power of the sun. Himin Solar Energy Group, organised a food festival in China’s eastern Shandong province to show off the apparatus. It wants to convince chefs and home cooks to try out their invention, claiming it reduces carbon emissions and still cooks a mean bowl of noodles. The chefs insert food into a mirrored vacuum tube. The sun’s heat is concentrated in the tube, cooking the dish. Roughly 600 million of China's 1.4 billion people still cook with coal, wood or other biomass, according to a 2016 report by the Global Alliance for Clean Cookstoves. The Chinese government has been trying to reduce carbon emissions for years, i
