What You'll Learn
China's air pollution problem
China recognized the severity of the problem and has implemented various measures to tackle air pollution. In 2013, the country released its Air Pollution Action Plan, which helped significantly improve air quality between 2013 and 2017. Beijing, a city notorious for its poor air quality, reduced PM2.5 levels (atmospheric particulate matter) by 33%. Other major cities like Shanghai, Shenzhen, and Guangzhou restricted the number of cars on the road and introduced all-electric bus fleets.
China has also addressed the issue at its source by reducing coal consumption and increasing the use of renewable energy. The country prohibited new coal-fired power plants and shut down older ones in highly polluted regions. Additionally, China has invested in afforestation and reforestation programs, planting over 35 billion trees across 12 provinces.
The World Bank has supported China's efforts by financing investments in energy efficiency and renewable energy through the Innovative Financing for Air Pollution Control Program. This program has helped China reduce carbon dioxide emissions and contribute to blue skies in the Jing-Jin-Ji region.
Despite these efforts, China still faces challenges. It remains the world's largest producer and consumer of coal, and its recent economic recovery efforts have led to an increase in coal-power capacity. However, China is committed to improving air quality and has set targets for reducing hazardous airborne particles by 10% by 2025. The country is also promoting the use of electric vehicles and expanding funding for clean heating in the northern region.

China's plastic waste crisis
China has taken steps to address its plastic waste crisis domestically as well. In 2008, a ban was enacted to prohibit supermarkets and shops from providing free plastic bags, encouraging the use of cloth bags. Additionally, the production, sale, and use of ultra-thin plastic bags were banned. More recently, in 2021, China launched a five-year action plan to phase out single-use plastics, promote alternatives, and boost recycling. This plan included policies targeting plastic shopping bags and disposable plastics in restaurants.
While China's import ban may positively impact its environmental sustainability in the long run, it has also highlighted the global reliance on China for waste management. The ban has resulted in increased costs for consumers, the closure of recycling facilities, and decreased plastic waste diversion. However, experts believe that this crisis could be an opportunity to develop better solutions for managing waste and addressing the world's growing throwaway culture.
Overall, China's plastic waste crisis is a critical issue that requires continued efforts to reduce plastic consumption, improve recycling infrastructure, and promote sustainable alternatives to single-use plastics.

China's coal consumption
China is the world's largest consumer and producer of coal. In 2021, its coal consumption and production accounted for more than half of the world's total. Coal consumption in China is closely linked to the country's industrialization. Between 2002 and 2013, coal accounted for 77% of the increase in primary energy demand, driven mainly by coal consumption in the cement, chemical, and steel sectors. In 2020, 60% of coal was used for electricity and heat generation, with industry accounting for one-third of the demand. China's installed coal-based power generation capacity was 1080 GW in 2021, about half of the total installed capacity of power stations in China.
In recent years, China has imported approximately 8-10% of the coal it uses, with net imports accounting for a smaller share of around 6-7%. In 2020, Chinese coal imports reached a record 304 million tonnes, rising to 323 million tonnes in 2021. China's import requirements have been driven by surging electricity demand, domestic transportation bottlenecks, economic factors, and environmental and safety considerations.
To address air pollution, China has implemented various measures, including prohibiting new coal-fired power plants and shutting down old plants in polluted regions. The government has also introduced plans to reduce coal consumption and increase the use of clean and renewable energy. In 2021, China's coal consumption accounted for more than 20% of global CO2 emissions from fossil fuels. Chinese policymakers aim to “strictly control” coal use and start phasing it down in the coming years.

China's water pollution
China's rivers have suffered significant water quality impairments due to economic development. The elevated input of anthropogenic nutrients, such as total dissolved nitrogen (TDN) and total dissolved phosphorus (TDP), has reduced water quality and endangered human and aquatic health. Additionally, excess nutrients transported from rivers to lakes and oceans have resulted in frequent blooms and red tides. China's northern regions are particularly arid due to their natural geography and climate patterns, but human activities have exacerbated these effects. Climate change has shortened rainy seasons and melted glaciers that feed the Yellow River, causing northern rivers to dry up. Overgrazing by livestock has also turned grasslands into sandy deserts, further contributing to water scarcity.
Agricultural practices and factories are significant contributors to water pollution. Inefficient irrigation methods in agriculture increase water costs, and agricultural chemicals like pesticides and fertilizers can turn into toxic runoff, polluting groundwater. Factory pollution, both accidental and intentional, releases untreated waste and chemicals into rivers. About 80% of China's dirtiest factories are located on rivers, lakes, or in heavily populated areas, increasing the potential for water pollution. In 2005, a chemical explosion at a petrochemical plant spilled 100 tons of pollutants into the Songhua River, leaving 3.8 million residents without water for four days.
While China has implemented measures to address water pollution, such as the Water Pollution Prevention and Control Law, the current water governance structure needs to become more flexible and adaptable to regional trends and sources of nutrient loadings to further reduce pollutant loadings and nutrient concentrations.

China's overfishing
China has made efforts to address its pollution problem in recent years, particularly regarding air quality. An anti-pollution campaign launched in 2013 focused on reducing PM2.5 particulate matter, which led to a 50% decrease in average PM2.5 concentration by 2019. During the COVID-era, China continued to improve air quality, and the average annual concentration of PM2.5 in major Chinese cities further decreased by 2022.
However, other pollution issues persist, such as the increase in O3 concentration before the pandemic, contributing to a rise in ozone-related mortality. China's economic initiatives, such as the Belt and Road Initiative, have also been criticized for lacking clear environmental guidelines and leading to negative ecological consequences in various countries. Additionally, China is the world's leading generator of plastic waste, with a significant portion ending up in the environment.
Now, on to the topic of China's overfishing:
China's distant-water fishing fleet travels far from its coast, and the number of these vessels is estimated to range from 2,600 to 17,000. These ships are often so large that they catch in a week what local boats might catch in a year, causing significant depletion of fish populations. China's fishing activities have been linked to illegal practices, such as encroaching on territorial waters, tolerating labor abuses, and catching endangered species.
The South China Sea has been a particular area of tension, with competing territorial claims between China, Vietnam, and other bordering states. Overfishing, combined with island-building and clam harvesting, has devastated significant portions of the region's shallow coral reefs, which serve as vital nursery grounds for many fish species. China's state policy has been implicated in driving overfishing in this region, using it to assert sovereignty.
China's global fishing operations have raised alarms, with growing numbers of Chinese commercial ships fishing near ecologically diverse areas like the Galápagos Islands, just outside Ecuador's exclusive economic zone. China's fishing fleet has targeted various regions, including West Africa, Latin America, and the Indian Ocean, often exploiting weaker enforcement in these areas.
The United States is leading the international response, encouraging China to increase monitoring and enforcement to ensure legal and sustainable fishing practices. China's overfishing has significant ecological and geopolitical implications, and addressing this issue is crucial for the health of marine ecosystems and international relations.
