China's Pollution Battle: Strategies And Successes

China's environmental crisis, caused by decades of rapid industrialization, poses a threat to the health and livelihoods of its 1.4 billion people and the global fight against climate change. China's carbon emissions and environmental degradation endanger global efforts to combat climate change, economic growth, public health, and government legitimacy. China's leaders have responded with measures to improve air quality, such as signing the 2015 Paris Agreement on climate and pledging to be carbon neutral by 2060. Despite these efforts, China still faces significant challenges in balancing economic growth with environmental and social welfare.

China has banned the importation of electronic waste

China has long been aware of the environmental and health consequences of electronic waste. In 2018, the Chinese government implemented a waste import ban, banning the import of several types of waste, including plastics with a contamination level of above 0.05%. This was an effort to stop the deluge of soiled and contaminated materials that was overwhelming Chinese processing facilities and causing yet another environmental problem.

China's waste import ban has greatly affected recycling industries worldwide, as China had been the world's largest importer of waste plastics and processed hard-to-recycle plastics for other countries, especially in the West. China is home to about 20% of the world's population but only has 7% of its freshwater sources. Overuse has led to severe shortages, and industry along China's major water sources has polluted supplies. Construction of hydropower dams along major rivers has also damaged ecosystems. The government released a plan in 2015 to prevent water pollution by placing controls on polluting industries, and the quality of surface waters has improved since.

China's ban on importing waste has stalled global recycling. The country's plastics imports have plummeted by 99%, leading to a major global shift in where and how materials are processed. Without China to process plastic bottles, packaging, and food containers, experts warn of exacerbation of the already massive waste problem posed by a throwaway culture. The ban has also affected the import of electronic waste. Cheaper labor and lax environmental standards attracted e-waste from developed countries that could save much of the cost of processing the waste domestically. By 2000, China was the largest importer of e-waste in the world, with about 70% of electronic waste globally generated ending up in China.

The Chinese government has taken action to regulate e-waste management, but ineffective enforcement, legislative loopholes, and the pervasiveness of informal recycling have been obstacles to mitigating the consequences of e-waste. The Air Pollution Action Plan, released in September 2013, became China's most influential environmental policy. It helped the nation make significant improvements in its air quality between 2013 and 2017, reducing PM2.5 levels (atmospheric particulate matter) by 33% in Beijing and 15% in the Pearl River Delta.

The government prohibited new coal-fired power plants

China's rapid industrialization has resulted in intense levels of air pollution, causing serious social, economic, and political problems. The country's leaders have responded with measures to improve air quality, but they face significant challenges in balancing economic growth with environmental and social welfare.

China's carbon emissions and environmental degradation threaten global efforts to fight climate change and endanger economic growth, public health, and government legitimacy. As the world's largest source of greenhouse gas emissions, China suffers from notoriously bad air pollution, mainly due to its carbon-intensive industries.

To address these issues, the Chinese government has implemented policies to curb emissions and mitigate further degradation. One such measure was prohibiting new coal-fired power plants and shutting down old ones in the most polluted regions, including the city clusters of Beijing-Tianjin-Hebei and the Pearl and Yangtze Deltas. This decision aimed to reduce air pollution and mitigate the public health crisis caused by toxic air, which kills more than 1.1 million people in China annually.

The prohibition of new coal-fired power plants is a significant step in China's battle against air pollution. Coal has been a cheap but highly polluting source of energy, contributing significantly to the country's air pollution crisis. By halting the construction of new coal-fired power plants, China is actively working towards reducing emissions and improving air quality.

This prohibition is part of a broader strategy to decrease coal consumption by improving energy efficiency in the industrial and building sectors and increasing the supply of renewable energy. The government has also invested in renewable energy projects, such as distributed solar PV systems, and promoted the use of clean energy vehicles. These measures demonstrate China's commitment to addressing its environmental challenges and contributing to the global fight against climate change.

Beijing implemented policies to curb emissions

Beijing has implemented policies to curb emissions and stem further degradation. Notably, Beijing signed the 2015 Paris Agreement on climate and pledged to be carbon neutral by 2060.

Beijing has also established a system of laws and regulations at the national and city levels, with supporting enforcement and supervision. The system gives clear guidance on the mandatory responsibility of city and district-level governments in developing and implementing clean air actions. This includes the closing of high-pollution enterprises, retrofitting and transitioning power plants, renovating and replacing coal-fired boilers, and phasing out heavy-duty diesel/gasoline vehicles.

Since 2013, Beijing has adopted more systematic and intensive measures for air pollution control. By the end of 2017, fine particulate pollution (PM2.5) fell by 35% and by 25% in the surrounding Beijing-Tianjin-Hebei region. Much of this reduction came from measures to control coal-fired boilers, provide cleaner domestic fuels, and industrial restructuring. Over this period, annual emissions of sulfur dioxide, nitrogen oxides, particulate matter, and volatile organic compounds in Beijing decreased by 83%, 43%, 55%, and 42%, respectively.

Beijing has also restricted the number of cars on the road and started introducing all-electric bus fleets. The city has also transitioned residential heating from coal to electric or gas, and put a cumulative number of 610,000 electric vehicles on the road.

China has improved surface water quality

China's environmental crisis, caused by decades of rapid industrialization, has resulted in the contamination of water bodies, threatening the health and livelihoods of its citizens. In 2001, 44% of China's surface waters were deemed unusable due to pollution, with industrial discharges rendering many waterways unfit for direct human use. However, China has made notable strides in improving its surface water quality, particularly since 2003.

Research indicates a marked improvement in China's inland surface water quality over the past two decades. This progress is attributed to reduced discharges in the industrial, rural, and urban residential sectors. China's ongoing modernization has also played a role in expanding access to safe drinking water. In 2000, more than 245 million people drank water from untreated sources, a number that decreased to 89 million within less than two decades.

The Chinese government has implemented measures to address water pollution, including the 2015 plan to control polluting industries and restrict farming near major rivers. These efforts have yielded some success, with only 6.9% of surface water in river basins considered "Below Grade V" in 2018, indicating severe pollution. While groundwater pollution remains a challenge, the quality of China's surface waters, such as lakes, rivers, and streams, has improved.

China's battle against water pollution is far from over. The growing discharges from the agricultural sector threaten the gains made in other sectors. Additionally, providing safe drinking water to over 1.4 billion people remains a significant undertaking. The water crisis, coupled with negligent farming practices, overgrazing, and climate change impacts, has led to desertification, with over a quarter of China's arable land turning into deserts.

To summarize, China has made significant progress in improving its surface water quality since 2003, reducing industrial, rural, and urban residential discharges. However, ongoing challenges, particularly from agricultural pollution, and the need to provide safe drinking water to its massive population, persist.

The government has responded to desertification by planting billions of trees

China's environmental crisis, caused by decades of rapid industrialization, poses a threat to the health and livelihoods of its 1.4 billion people and the global fight against climate change. The country's carbon emissions and broader environmental degradation, including water scarcity and soil contamination, endanger economic growth, public health, and government legitimacy.

The Chinese government has responded to the country's pollution crisis in various ways, one of which is addressing desertification by planting billions of trees. Desertification, caused by both human and natural activity, transforms normal humid areas into dry desert conditions. More than one-quarter of China's arable land is becoming a desert due to the water crisis, negligent farming practices, overgrazing, and the effects of climate change.

To combat this, the Chinese government initiated the Great Green Wall, officially known as the Three-North Shelter Forest Program or the Three-North Shelterbelt Program, in the 1970s. This massive reforestation project aims to create a vast green barrier spanning approximately 4,828 kilometers long and up to 1,448 kilometers wide in certain regions, encompassing around 88 million acres of forests. The project involves planting windbreaking forest strips or shelterbelts to hold back the expansion of the Gobi Desert, which was growing at an alarming rate of 10,000 square kilometers per year in the 1980s.

The tree-planting program has had notable successes, such as reversing the desertification of the Gobi Desert, which was shrinking by more than 2,000 square kilometers per year in 2022. It has also helped stabilize the soil, enhance local microclimates, and reduce the frequency and intensity of dust storms. Additionally, newly planted forests absorb large amounts of carbon dioxide, aiding in the mitigation of climate change.

However, there have been challenges and criticisms regarding China's tree-planting efforts. The survival rate of trees has been a critical issue, as many struggle to adapt to the arid and nutrient-poor desert environment. Monoculture plantations, such as the large-scale planting of poplars, have led to reduced biodiversity. Critics argue that a sole focus on tree-planting numbers overlooks other vital aspects of ecosystem restoration, such as grassland rehabilitation and sustainable land management practices.
