Improving China's Air Quality: Strategies For A Brighter Future

China's economic growth has come at a cost: air pollution, which has become a public health crisis, killing more than 1.1 million people annually. The country has made significant strides in improving air quality, particularly in Beijing, which was once shrouded in smog. A combination of short-term and long-term emission controls, such as the Air Pollution Action Plan, have proven effective in reducing PM2.5 levels and improving air quality. Beijing has implemented various measures, including driving bans, incentives for electric vehicles, and modernizing its bus fleet. The city has also focused on reducing coal consumption and improving heating systems, with a broader shift towards cleaner and more sustainable urban transportation. China is also promoting the use of electric vehicles and expanding funding for clean heating, while also addressing the financing challenges for renewable energy projects.

Reducing coal consumption

China's economic growth has come at a cost to the environment and public health. The country has been working to improve its air quality, and one of the key strategies is reducing coal consumption.

China's state council has stated that it will "strictly and reasonably" control total coal use to improve air quality. The country aims to reduce coal consumption in the Beijing-Tianjin-Hebei region and surrounding areas by about 10% from 2020 levels by 2025. This involves shutting down industrial sites and improving heating systems. China has also prohibited the construction of new coal-fired power plants and shut down several old plants in the most polluted regions, including the Beijing-Tianjin-Hebei and the Pearl and Yangtze Deltas areas.

To further reduce coal consumption, China is focusing on improving energy efficiency in the industrial and building sectors. This includes increasing the supply of renewable energy sources, such as distributed solar PV systems, and replacing coal with natural gas. Additionally, China is investing in clean energy vehicles and electric buses, aiming to have 600,000 electric buses by 2025.

The efforts to reduce coal consumption and improve air quality are yielding positive results. Between 2013 and 2017, Beijing reduced PM2.5 levels by 33%, and the annual average PM2.5 level dropped to 58µg/m³, a decrease of 35%. The Beijing-Tianjin-Hebei region also experienced a significant improvement, with a 25% reduction in PM2.5 concentrations during the same period. These reductions in air pollution are expected to increase the life expectancy of residents, with Beijing's improvements potentially resulting in an additional 4.6 years for locals.

Improving heating systems

China has been taking steps to improve its air quality, and one of the major contributors to air pollution is the heating and cooling systems used. Here are some ways China can improve air pollution by focusing on heating systems:

• Adopting Clean Energy Sources: China should promote the use of clean and renewable energy sources for heating systems. This includes encouraging the use of heat pumps, which have no direct pollutant emissions, and supporting the development of new and clean energy technologies.
• Reducing Coal Consumption: China has already taken steps to control total coal use and close coal-fired power plants, particularly in highly polluted regions. Continuing to reduce coal consumption will help lower emissions of hazardous airborne particles, specifically PM2.5.
• Upgrading Traditional Industries: China intends to increase credit and financing support for the modernization of traditional industries. This includes investing in more efficient and environmentally friendly heating technologies, such as energy-efficient heat recovery ventilators or air-to-air heat exchangers.
• Strict Emission Controls: China can implement strict emission reduction policies for heating systems, targeting both short-term and long-term goals. This includes setting standards for pollution emission limits from heating appliances, with a focus on reducing PM2.5, NOx, NH3, NMVOCs, CO, and SO2 emissions.
• Energy Efficiency: Improving the energy efficiency of heating systems can help reduce pollution. This includes utilizing advanced technologies that recover waste heat and promoting the use of well-insulated buildings to decrease energy loss, reducing the overall demand for heating.
• Indoor Air Quality: Focusing on improving indoor air quality can also help reduce pollution from heating systems. This includes routine maintenance, regular air filter changes, and proper ventilation in homes and buildings. Advanced designs for new homes can also incorporate mechanical features that bring in more outdoor air, improving overall air quality.

By implementing these strategies, China can significantly improve air pollution associated with heating systems, contributing to the country's overall goal of cleaner air and improved public health.

Using electric vehicles

China has been taking several measures to improve its air quality and reduce air pollution. One of the key initiatives is the promotion of the use of electric vehicles (EVs) to reduce carbon emissions. The country has set ambitious targets to establish fast-charging stations for electric vehicles in key regions, including Beijing, Tianjin, and Shanghai.

The shift towards electric mobility is a significant step in reducing air pollution and greenhouse gas emissions. As part of this initiative, China has introduced all-electric bus fleets in major cities like Shanghai, Shenzhen, and Guangzhou. This move is particularly important given the sharp increase in the number of vehicles in the country, which has had a detrimental impact on air quality.

China's focus on electric buses is notable, with the country owning 99% of the world's 385,000 electric buses in 2023, and this number is expected to grow to 600,000 by 2025. This not only showcases China's commitment to reducing air pollution but also positions it as a global leader in the electric mobility market.

To encourage the use of electric vehicles, China has implemented various incentives and policies. For example, the country has introduced license plate lotteries, driving bans, and incentives for scrapping older, polluting vehicles. These measures are designed to make electric vehicles more accessible and attractive to consumers, while also phasing out polluting cars.

In addition to the efforts in the transportation sector, China is also addressing air pollution through other initiatives. These include the development of new and clean energy sources, increasing natural gas production, and reducing coal consumption in the industrial and building sectors. By diversifying its energy sources and decreasing its reliance on coal, China aims to further reduce air pollution and improve the health and well-being of its citizens.

Controlling emissions from vehicles

China's rapid economic growth, population increase, and surging number of vehicles have put immense pressure on the country's environment, particularly its air quality. To control emissions from vehicles, China has implemented several measures:

Incentivizing the use of electric vehicles

China has become a leader in electric mobility, with 99% of the world's 385,000 electric buses. The country plans to increase this number to 600,000 by 2025. Fast-charging stations will be available at no less than 80% of highway service areas in key regions, including Beijing, Tianjin, and Shanghai, by 2025, and no less than 60% in other regions.

Restricting the number of cars on the road

Large cities like Shanghai, Shenzhen, and Guangzhou have restricted the number of cars on the road. They have also started introducing all-electric bus fleets.

Low Emission Zones (LEZs)

Beijing has implemented Low Emission Zones (LEZs) to reduce air pollution and enhance air quality within defined geographical boundaries. LEZs restrict access for polluting vehicles, driving the adoption of cleaner, emission-compliant modes of transportation. Older vehicles are retrofitted with emission reduction technology.
