Reducing PM2.5 levels
China has implemented various measures to reduce PM2.5 levels and improve air quality. One of the key strategies has been the introduction of the Air Pollution Action Plan in 2013, which significantly improved air quality between 2013 and 2017, reducing PM2.5 levels by 33% in Beijing and 15% in the Pearl River Delta. The plan set specific targets, tightened emissions standards, and closed loopholes in enforcement, with a focus on the transport sector. Beijing also established Low Emission Zones (LEZs) to restrict access for polluting vehicles and promote cleaner modes of transportation.
Another important initiative is the Three-year Action Plan for Winning the Blue Sky War, introduced in 2018. This plan mandates an 18% reduction in PM2.5 levels in 231 cities that have not met government standards, addressing ground-level ozone, a primary pollutant. China is also addressing PM2.5 levels by promoting electric vehicles and expanding the infrastructure for their use, with fast-charging stations planned for key regions. The country aims to reduce coal consumption in highly polluted regions, such as Beijing-Tianjin-Hebei, and encourage the development of new and clean energy sources, including increasing natural gas production.
In addition to these measures, China has implemented aggressive afforestation and reforestation programs, such as the Great Green Wall, planting over 35 billion trees across 12 provinces. Beijing, specifically, has made strides in improving air quality, including reintroducing bike-sharing schemes and expanding its subway system. These efforts have resulted in significant gains, with research suggesting that the reduction in air pollution could lead to an increase in life expectancy of 2.4 years for the average citizen.

Improving energy efficiency
China has taken several measures to combat air pollution, including improving energy efficiency. Energy generation is one of the greatest sources of air pollution, and improving energy efficiency can help to reduce the amount of pollution that is generated.
China has made significant strides in improving its air quality, with national air pollution action plans seeing substantial reductions in pollution levels and associated health risks. Notably, China has tackled the root causes of air pollution, such as economic growth, population increase, and the surging number of vehicles. Beijing, for instance, has implemented initiatives like Low Emission Zones (LEZs) to restrict access for polluting vehicles and drive the adoption of cleaner, emission-compliant modes of transportation.
To improve energy efficiency, China can focus on making systems more efficient so that they demand less power to operate. This can be achieved through the smart design of combustion units, utilizing renewable energy sources, and improving the efficiency of fossil fuel power plants with carbon capture and storage technology. Additionally, China can invest in "green" building design, construction, and operation, incorporating natural lighting and heating methods to reduce reliance on artificial lighting and fossil fuels for heating.
China has also made efforts to improve energy efficiency in vehicles, appliances, and equipment. The country has encouraged the use of energy-efficient appliances, such as refrigerators, ovens, and dishwashers, which are becoming more affordable and accessible. These energy-efficient appliances reduce energy consumption and, consequently, lower energy bills and carbon pollution.
Furthermore, China has explored ways to enhance energy efficiency in its industries. For example, a 2015 study examined the effectiveness of an energy efficiency program in China's cement industry. The study projected that by 2030, the program would decrease carbon dioxide levels by 5-8%, sulfur dioxide levels by 15-25%, nitrogen oxide levels by 12-20%, and particulate matter pollution levels by 3-5%.
By implementing these measures and focusing on improving energy efficiency, China is taking significant steps toward reducing air pollution and promoting sustainable development.

Transitioning to electric vehicles
China's economic growth has historically been fuelled by fossil fuels, which has caused serious air pollution issues. The transportation sector, in particular, is responsible for about 10% of China's total emissions. As a result, China has implemented policies incentivizing the use of electric vehicles (EVs), which are seen as a clean alternative to conventional automobiles.
China has set ambitious targets for the electrification of its transport sector. The State Council's Action Plan for Achieving Carbon Peaks by 2030 aims for a 40% share of new energy and clean energy-powered transport vehicles by that year. As of June 2022, out of 312 million civilian vehicles, only 8.104 million were battery electric vehicles (BEVs), representing roughly 2.6% of the total.
Studies have shown that increased adoption of BEVs can lead to improved air quality. A study of three Chinese first-tier cities found that higher BEV usage resulted in significant reductions in PM2.5 and O3 concentrations. Another study found that replacing fuel vehicles with BEVs for equivalent mileages generally contributed to better emission reductions. However, the impact of BEVs on air quality can vary across different cities, months, and vehicle models, with a notable reduction in efficacy during winter.
While some studies have questioned the environmental benefits of electric cars in China, citing the high emissions from the power plants that generate the electricity to operate them, the overall trend and focus on transitioning to electric vehicles is clear. This shift towards electric mobility is a key part of China's strategy to achieve carbon neutrality and improve air quality in its cities.

Reducing coal consumption
China's economic growth has substantially relied on fossil fuels, causing serious air pollution issues. Coal combustion in China is responsible for more than 20% of global carbon dioxide (CO2) emissions, and coal-based process emissions account for a few additional per cent. Coal is also a key contributor to ambient air pollution, which causes an estimated 1.1 million deaths annually in China.
Recognizing the heavy costs of coal, China's leaders have sought to reduce coal consumption and pollution by introducing various policy measures. During the 13th Five-Year Plan (2016–2020), China introduced policies aimed at reducing coal's share of the energy mix, including capping coal use, removing dispersed coal from urban areas, switching from coal to natural gas heating, closing inefficient coal-fired boilers, tightening CO2 emissions standards, and strengthening efficiency standards in power plants.
In addition to these policies, China has also focused on working with the largest coal-consuming sectors, such as power, iron and steel, cement, and chemicals, to scale up more efficient technologies and reduce coal consumption. These sectors have been incentivized to switch to natural gas and renewables to lower their emissions.
China has also implemented initiatives like Low Emission Zones (LEZs) in cities like Beijing, restricting access for polluting vehicles and driving the adoption of cleaner, emission-compliant modes of transportation.
Despite these efforts, China still faces challenges in reducing coal consumption, as it consumes over half of the world's coal and has immense proven reserves. There are also plans to build more coal-fired power plants in the future, indicating that phasing out coal will be a complex and lengthy process. However, China has demonstrated a commitment to decarbonization by setting a goal of achieving carbon neutrality by 2060, which implies a dramatic reduction in coal use over time.

Afforestation and reforestation
China has implemented aggressive afforestation and reforestation programs to combat air pollution. The country has invested over $100 billion in such programs, exceeding the forestry expenditure per hectare of the US and Europe. The most notable of these programs is the Great Green Wall, which has seen more than 35 billion trees planted across 12 provinces.
China's forest cover has expanded in recent decades, with the country's State Council Information Office reporting that 36.3 million hectares of forests were planted from 2016 to 2020, and roughly 15 million hectares from 2011 to 2015. The National Forest Conservation Program, launched in the wake of the 1998 Yangtze River floods, has played a significant role in this expansion. The program's goals have expanded in recent years to include fighting local air pollution and climate change.
The Three-North Shelterbelt Program is another large-scale initiative that aims to enhance forestation in China's northern regions, spanning 13 provinces, autonomous regions, or municipalities, and totaling 4.069 million square kilometers. The program offers subsidies to farmers and local communities to compensate for lost income from logging and aims to boost tree coverage, stabilize soil, prevent sandstorms, and enhance ecological conditions in arid and semi-arid zones.
China has also introduced a revised Forest Law, which bans the buying, transporting, or processing of illegal timber and requires processing companies to establish data records of raw materials and products. The law also strictly controls the logging of natural forests and limits annual harvest volumes.
These afforestation and reforestation efforts have had a significant impact on China's environment and economy. Forests now cover roughly 23% of China's territory, providing habitat for diverse species and a source of livelihood for millions of people. They also help to combat climate change through carbon sequestration and reduce air pollution by absorbing particulate matter. Additionally, increasing forest coverage can enhance eco-tourism, providing richer biodiversity and more scenic landscapes that attract visitors.
