China's War On Air Pollution: Strategies And Successes

China has made significant efforts to reduce air pollution, which has been a prominent environmental issue in the country. The Chinese government has implemented stricter regulations and invested substantial sums to combat this problem. The main sources of air pollution in China include industry, transportation, coal power plants, and household solid fuel usage. China's past reliance on fossil fuels, particularly coal, has contributed to high levels of harmful emissions, including carbon dioxide, sulfur dioxide, nitrogen oxide, and particulate matter (PM2.5 and PM10). The government's actions to reduce air pollution have included enforcing the Operation National Sword policy to monitor and reduce contaminated waste imports, tightening vehicle exhaust rules, and transitioning to eco-friendly energy sources. These efforts have resulted in notable decreases in air pollution levels, with a 23.6% reduction in PM2.5 concentrations between 2013 and 2015 in key cities. However, the rapid industrialization and urbanization in China continue to pose challenges in maintaining stable economic growth while improving air quality and public health.

The Chinese government has enforced stricter regulations on air pollution

The Chinese government's efforts to reduce air pollution have included diversifying energy sources away from coal, which has been a major contributor to harmful emissions. In 2015, the Beijing government temporarily shut down industrial facilities and reduced car emissions to achieve a "Parade Blue" sky for the 70th-anniversary celebrations of World War II, resulting in a significant decrease in PM2.5 concentrations.

China has also invested significant financial resources into tackling air pollution, with the Academy for Environmental Planning pledging $277 billion in 2013 to combat urban air pollution. The Innovative Financing for Air Pollution Control in Jing-Jin-Ji Program has supported the implementation of the government's Air Pollution Control Action Plan, focusing on controlling air pollutants at their source by improving energy efficiency and expanding clean energy.

Furthermore, the government has implemented policies to address specific sources of pollution, such as Operation National Sword (ONS), which aimed to monitor and more stringently review recyclable waste imports, reducing contamination and the environmental concerns associated with them.

While China's efforts to reduce air pollution have had positive outcomes domestically, some analyses suggest that the removal of aerosols from the atmosphere has contributed to an increase in the rate of global warming since 2010. However, experts argue that this is a result of the "'unmasking' of pre-existing warming", and that the lives saved by improved air quality in China outweigh the negative climate consequences.

They have reduced coal consumption and closed polluting factories

China's air pollution has been caused in large part by the country's consumption of solid fuels, including coal. In the early 2000s, China's rapid industrialization led to a public outcry in the run-up to the 2008 Beijing Olympics. The Chinese government has since taken steps to reduce the country's coal consumption and close polluting factories.

In response to the outcry, the government fitted scrubbers to coal power plants to curb the dirtiest emissions, leading to a 75% drop in sulphate emissions. China has also reduced its consumption of coal by replacing it with other energy sources. For example, in Chinese cities, coal stoves are being replaced with gas stoves and other space heating methods. However, in rural China, coal use seems to be increasing as it substitutes for biomass.

In addition to reducing coal consumption, China has also implemented other measures to improve air quality. For example, the Sino–Dutch Project studied around 140 household kitchens in five counties of three provinces. The kitchens were monitored for 24 hours before and after introducing a suite of improvements, including improved biomass stoves and biogas, which significantly reduced all pollutants.

Despite these efforts, China is still the world's biggest carbon emitter, and air pollution remains a serious issue. Beijing, for example, is a notoriously polluted city, where levels of PM2.5, the smallest and deadliest smog particles, have risen as high as 303 micrograms per cubic meter, more than 20 times the level considered safe by the World Health Organization. In response to such hazardous smog, Beijing has been forced to ban cars and close factories.

Overall, China has made progress in reducing coal consumption and closing polluting factories, but the country still has a long way to go in cleaning up its air and protecting the health of its citizens.

China has invested significant sums to tackle air pollution

China's past economic growth has been heavily reliant on fossil fuels, which has contributed to severe air pollution. To address this, the government has implemented various measures, including stricter regulations and initiatives to promote clean energy and reduce coal consumption. For example, the Operation National Sword (ONS) policy initiative, launched in 2017, aimed to monitor and more stringently review recyclable waste imports, reducing environmental concerns caused by contaminated recyclables.

The Innovative Financing for Air Pollution Control in Jing-Jin-Ji Program has also played a crucial role in supporting the government's Air Pollution Control Action Plan. This program focuses on controlling air pollutants at their source by improving energy efficiency and expanding clean energy sources. The International Bank for Reconstruction and Development (IBRD) provided a $500 million loan, leveraging five times that amount in financing for the government's air pollution control program.

China has also made efforts to reduce coal consumption and increase the supply of renewable energy. For instance, they have implemented pollution abatement measures such as installing equipment to remove particulate matter, flue gas desulfurization, and denitrification, as well as expanding the use of clean energy vehicles. These actions have contributed to a reduction in coal consumption and polluting industries while maintaining a stable economic growth rate.

While China's actions to reduce air pollution have had some success, it is important to note that they have also contributed to an increase in the rate of global warming. This is because the removal of aerosols from the atmosphere has unmasked the full effect of greenhouse gas-driven warming. Despite this unintended consequence, the measures are worth taking, as they have helped avoid numerous premature deaths per year.

They have banned solid waste imports and reduced plastic waste

China has long been the world's largest consumer of plastics and the biggest manufacturer, with a yearly average of 60 million tons. Until 2017, China was also the largest importer of plastic, accounting for 45% of global plastic waste since 1992. However, the country has been plagued by plastic pollution for decades, with only about 30% of its plastic waste being recycled.

In 2017, the Chinese government announced an import ban on solid waste, including several types of plastics and other recyclable waste. This ban came into effect on 1 January 2018, with the aim of reducing air and water pollution caused by the waste-recycling industry. The policy, known as Operation National Sword, banned the import of most plastics and other materials headed for recycling processors in China, which had previously handled nearly half of the world's recyclable waste.

China's ban on solid waste imports has had significant repercussions on the global plastic waste trade. Municipalities and waste companies worldwide have been left scrambling for alternatives to manage their plastic waste. While the ban may lead to increased plastic pollution in the environment, especially in countries with high-risk mismanagement and high leakage rates, it also provides an opportunity to develop better solutions for a growing throwaway culture.

In addition to banning solid waste imports, China has also taken steps to reduce plastic waste within the country. The government has been phasing out single-use plastics in businesses, and several cities have restricted plastic shopping bags. These actions are in line with global efforts to reduce plastic waste, with the European Parliament banning single-use plastics and North American cities like Seattle and Vancouver taking similar measures.

Overall, China's ban on solid waste imports and its efforts to reduce plastic waste are part of a broader strategy to tackle air and water pollution and achieve carbon neutrality by 2060.

China has also focused on developing clean energy sources

China has invested significant sums into efforts to reduce air pollution. In 2013, China's Academy for Environmental Planning pledged $277 billion to combat the problem. Since then, China has focused on developing clean energy sources and reducing its consumption of coal.

In 2015, the Beijing government shut down industrial facilities and reduced car emissions to achieve a "Parade Blue" sky for the 70th-anniversary celebrations of the end of World War II. This action resulted in a PM2.5 concentration lower than the 35 μg/m3 national air quality standard, with an average Beijing PM2.5 concentration of 19.5 μg/m3—the lowest ever recorded in the capital.

China's strategy has been mainly focused on the development of other energy sources such as nuclear, hydro, and compressed natural gas. The country has also invested in solar power, with the Innovative Financing for Air Pollution Control in Jing-Jin-Ji Program supporting the installation of distributed solar PV systems in 2,553 rural households. This has contributed to blue skies in the Jing-Jin-Ji region and China's efforts to mitigate climate change.

In addition to developing clean energy sources, China has also focused on improving energy efficiency in the industrial and building sectors. This includes installing equipment to remove particulate matter, flue gas desulfurization, and denitrification, as well as expanding clean energy vehicles. China has also tightened rules governing vehicle exhausts, leading to a 75% drop in sulphate emissions.

While China's efforts to reduce air pollution have had a positive impact on public health, they have also contributed to a surge in global warming by removing the artificial cooling effect of pollution. However, despite this unintended consequence, the actions were worth taking to save lives, according to Duncan Watson-Parris at the University of California San Diego.
