China's War On Pollution: Strategies And Successes

China's rapid industrialization has resulted in various forms of pollution, causing widespread environmental and health problems. In 2013, China's government declared a war on pollution, implementing stricter regulations and policies to tackle air, water, and soil pollution. China's efforts to reduce pollution include transitioning to clean energy sources, promoting electric vehicles, investing in waste management, and collaborating with other countries to share its expertise. While China has made significant progress in improving its air quality and reducing pollution levels, it continues to face challenges in balancing economic progress and environmental sustainability.

Stricter government regulations on industrial pollution

China's rapid industrialization has led to significant ecological damage and public hazards, including widespread environmental and health issues. The Chinese government has responded with stricter government regulations to control industrial pollution, particularly air pollution.

In 2013, the State Council issued the Air Pollution Prevention and Control Action Plan, targeting a reduction in PM2.5 levels. The plan aimed to reduce coal consumption by closing polluting mills, factories, and smelters, and switching to eco-friendly energy sources. This was followed by the Three-year Action Plan for Winning the Blue Sky War in 2018, which mandated an 18% reduction in PM2.5 levels in 231 cities. China has also invested heavily in afforestation and reforestation programs, planting over 35 billion trees across 12 provinces.

To address water pollution, China has established strict regulations requiring polluting units to adopt measures to control wastes, residues, radioactive materials, and noise. The government has set up wastewater treatment plants and a system to monitor water quality. The National Specially Monitored Firms program directly monitors thousands of water-polluting firms and sewage treatment plants. China has also addressed sulfur dioxide pollution through the China IV gasoline standard, limiting sulfur in gasoline.

In terms of soil pollution, China has implemented the Soil Pollution Prevention and Control Law, allowing regulators to require liable parties to remediate agricultural land. The government has established a system to monitor soil quality and reduce the discharge of pollutants into the soil. Industries are required to limit their output or pay for contamination.

China is also a signatory to the Stockholm Convention, committing to control and phase out persistent organic pollutants (POPs). This includes eliminating the production, import, and use of certain pesticides and establishing an inventory of POP-contaminated sites. China has made progress in medical waste management, increasing its capacity to dispose of medical waste and providing expertise to other countries.

Reducing coal consumption and promoting clean energy

China is the world's largest consumer and producer of coal, with coal consumption and production accounting for more than half of the world's total in 2021. As such, reducing coal consumption is a key part of China's efforts to control pollution.

China has implemented various measures to reduce its coal consumption and promote clean energy. For example, the government has prohibited new coal-fired power plants and shut down several old plants in highly polluted regions, including Beijing, Tianjin, Hebei, and the Pearl and Yangtze Deltas. In 2013, the State Council issued an Action Plan for the Prevention and Control of Air Pollution, which aimed to reduce PM2.5 levels by over 10% from 2012 to 2017. The plan also included the development of twelve west-east air pollution control transmission corridors.

To promote clean and renewable energy, China has invested in projects such as the Innovative Financing for Air Pollution Control Program, which has helped reduce carbon dioxide emissions by 2.5 million tons per year. The country has also implemented the China Oil Consumption Cap Plan and Policy Research Project, which aims to reduce oil consumption and promote the safe and efficient use of oil resources. Additionally, China has introduced aggressive afforestation and reforestation programs, such as the Great Green Wall, which has seen the planting of over 35 billion trees across 12 provinces.

While China has made strides in reducing coal consumption and promoting clean energy, challenges remain. For instance, new coal mines and coal-fired power plants continue to be built, and coal remains a strong pillar of the country's energy mix, even as clean energy sources surge. China's top coal-consuming sectors, including power, steel, cement, and coal-chemicals, are projected to peak in coal consumption and carbon dioxide emissions by 2025.

Improving medical waste disposal

China has been reported to have improved its capacity for medical waste disposal since 2019. As of 2022, China was expected to dispose of 447,000 tonnes of medical waste, and its capacity is expected to handle approximately 2 million tonnes of waste annually. China has also been sharing its expertise in medical waste disposal with other countries, including Nepal, Myanmar, the Philippines, Laos, and Cambodia.

To improve medical waste disposal, it is essential to follow state and federal guidelines to remain compliant with local regulations. Healthcare providers should be familiar with guidelines provided by relevant government agencies, such as the Environmental Protection Agency (EPA) and the Resource Conservation and Recovery Act (RCRA) in the United States. Additionally, each state or region may have its own specific regulations and resources for medical waste management, which should be consulted.

It is crucial to identify and segregate medical waste at its point of origin. Medical waste can be categorised into several types, including sharps, pathological/anatomical waste, pharmaceutical waste, biological waste (including blood and blood-related products), microbiological waste, isolation waste, and contaminated animal waste. Proper segregation ensures compliance with regulations and protects the environment.

Safe disposal practices are critical to preventing injuries and infections among healthcare and support staff. For example, sharps containers must be closable, puncture-resistant, leak-proof, and properly labelled with biohazard symbols. Additionally, single-use, leak-resistant biohazard bags are typically used for containment, and all bags should be securely closed before disposal.

Furthermore, it is essential to improve waste destruction and disposal practices to meet national and international standards. Where feasible, safer and more environmentally sound treatments, such as autoclaving, microwaving, steam treatment, and chemical treatments, should be favoured over medical waste incineration. Raising awareness about the risks associated with healthcare waste and safe practices can also contribute to improved medical waste disposal.

Investing in afforestation and reforestation

China has been investing in afforestation and reforestation programs to combat environmental challenges and contribute to carbon neutrality by 2060. The country has pioneered the largest reforestation effort globally, and its forest expansion from 2001 to 2021 led the world, despite a 7.4% decrease in global tree cover during this period.

One of China's key initiatives is the Three-North Shelterbelt Program, also known as the Great Green Wall. Initiated in 1978, this program aims to plant nearly 90 million acres of new forest across northern China, spanning 13 provinces, autonomous regions, or municipalities, totaling 4.069 million square kilometers. The primary objectives of this program include soil stabilization, sandstorm prevention, and enhancing ecological conditions in arid and semi-arid zones. The Great Green Wall has been successful in reversing the desertification of the Gobi Desert, which was growing by 10,000 square kilometers per year in the 1980s but began shrinking by more than 2,000 square kilometers per year after the program's implementation.

However, critics have questioned the efficacy of China's reforestation efforts in addressing the socioeconomic drivers of desertification, such as overgrazing and unsustainable farming methods. Additionally, some scientists argue that the combination of exotic tree species and high-density planting in these programs could worsen water shortages and reduce biodiversity.

To compensate for lost income from logging, the Three-North Shelterbelt Program offered subsidies to farmers and local communities. China's reforestation efforts have also been supported by international financing initiatives, such as loans from the International Bank for Reconstruction and Development (IBRD) and grants from the Global Environmental Facility (GEF). These financial resources have been crucial in scaling up the country's environmental initiatives.

Another notable initiative is the Natural Forest Protection Project, which aims to halt commercial logging to prevent further deforestation and habitat loss. China has also implemented the Grain for Green Program, the South China Slopes Land Conversion Program, and the Ant-Forest Program, all contributing to its ambitious environmental goals.

Promoting electric vehicles and reducing road transport

China has been taking several measures to control pollution, especially air pollution, which has been a major concern for the country. One of the key strategies has been promoting electric vehicles (EVs) and reducing road transport emissions.

Promoting Electric Vehicles

China has been a world leader in the electric vehicle industry, and this has been largely due to the strong support and incentives provided by the government. The country started providing financial subsidies to EV companies producing buses, taxis, and cars for individual consumers as early as 2009. EV consumers in China have also benefited from government subsidies and tax breaks for several years. The government support, along with the push for lithium batteries, has helped China dominate the EV market, with sales of over 6 million EVs in 2022, accounting for half of the global sales.

Reducing Road Transport Emissions

Road transport is a significant contributor to China's carbon emissions, accounting for about 10% of the country's total carbon emissions as of 2022. To reduce road transport emissions, China has been focusing on electrification and clean power. The country has implemented various financial support policies, such as exemptions on consumption tax for EV producers and fuel cell vehicles, and continued vehicle purchase tax incentives for EV buyers. Additionally, China has been promoting fleet electrification, advanced emission inspection systems, and the development of new energy vehicles (NEVs).

China's efforts to reduce road transport emissions are aligned with its national climate plan, which aims for carbon dioxide emissions to peak in 2030 and the country to become carbon-neutral by 2060. Through these policies and technology breakthroughs, China aims to cut its road transportation emissions by up to 95% over the next 40 years, significantly improving air quality and reducing health risks associated with air pollution.
