Solving China's Air Pollution Crisis

China's rapid economic growth has come at a significant environmental cost, with the country facing an unprecedented environmental health crisis. In response, the Chinese government has implemented various solutions to combat air pollution, particularly targeting PM2.5, the most harmful type of air pollutant. These solutions include aggressive afforestation and reforestation programs, such as the Great Green Wall, which involved planting over 35 billion trees across 12 provinces. China has also focused on reducing coal consumption and increasing the use of natural gas and clean energy sources, such as electric vehicles. Additionally, the government has introduced action plans, like the Air Pollution Prevention and Control Action Plan, to reduce emissions and improve air quality, with a particular emphasis on ozone pollution. The COVID-19 pandemic also played a role in temporarily improving air quality due to reduced industrial and economic activities. Despite these efforts, China's battle against air pollution is ongoing, and more work is needed to sustain and build upon the improvements made.

Reducing PM2.5 levels

China has implemented a variety of measures to reduce PM2.5 levels, deemed the most harmful type of particulate matter. In 2013, the country launched a national air quality action plan, aiming to reduce PM2.5 levels in key city clusters. This plan helped China achieve significant improvements in air quality, with a 33% reduction in PM2.5 levels in Beijing and a 15% reduction in the Pearl River Delta by 2017.

To further reduce PM2.5 levels, China introduced the Three-year Action Plan for Winning the Blue Sky War in 2018. This plan mandates an 18% reduction in PM2.5 levels in 231 cities that had not yet met the government standard, with an average target of 35µg/m³. This action plan addressed ground-level ozone, a primary pollutant in many cities, which is created by volatile organic compounds reacting with nitrogen oxides from vehicles.

China has also focused on reducing its reliance on coal, the largest source of air pollutants and greenhouse gas emissions in the country. The government has prohibited new coal-fired power plants and shut down older ones in highly polluted regions. Additionally, China is investing in renewable energy sources such as wind and solar power, with the world's largest investment in these sectors. These efforts are helping to reduce PM2.5 levels and improve air quality.

Aggressive afforestation and reforestation programs, such as the Great Green Wall, have also been implemented. With over $100 billion in investments, China has planted more than 35 billion trees across 12 provinces, exceeding the forestry expenditure of the US and Europe. These initiatives contribute to the absorption of PM2.5 and other pollutants, improving air quality.

Furthermore, China has targeted heavy industry, a significant contributor to air pollution. While it is a challenging sector due to job provision and powerful state-owned companies, there has been progress in reducing overcapacity in steel, cement, glass, and power sectors. Factories have been shuttered, relocated, or mandated to scale back production or install expensive air scrubbers, contributing to reduced PM2.5 emissions.

Improving energy efficiency

China's heavy reliance on coal to meet its energy demand has resulted in severe air pollution, with coal consumption accounting for 66% of the energy mix. To address this issue, the country has implemented several measures to improve energy efficiency and reduce air pollution.

One key strategy is the development and utilisation of clean, renewable energy sources. China has invested significantly in wind and solar power, with the goal of replacing coal as the primary energy source. This includes the installation of distributed solar photovoltaic (PV) systems in open spaces along highways, roundabouts, and near tunnel exits, with the generated electricity being sold to the state power grid. As a result, China has the largest solar PV capacity globally, having deployed 130 GW of PV capacity by 2017.

In addition to renewable energy sources, China has also focused on improving energy efficiency in the industrial and residential sectors, which account for half of the country's coal consumption. For example, in Datong, the largest coal-producing region, the Wangping Power Company has installed two heat recovery units and a 21-kilometer heat pipeline to Huairen County with financing from the Innovative Financing for Air Pollution Control Program. This program has supported 27 subprojects in the areas of energy efficiency, renewable energy, and emission control, leveraging $1.3 billion in total investment.

Furthermore, China has introduced aggressive afforestation and reforestation programs, such as the Great Green Wall, planting more than 35 billion trees across 12 provinces. These initiatives have helped improve air quality and contributed to the country's efforts to combat climate change.

While China has made significant strides in improving energy efficiency and reducing air pollution, it continues to face challenges. The escalating reliance on fossil fuels, particularly coal, remains a concern, with coal imports and coal-fired power generation on the rise. Balancing economic progress and environmental sustainability remains a delicate task for the nation.

Investing in clean energy

China has the world's largest solar photovoltaic (PV) capacity, with 130 GW of PV capacity deployed by 2017. However, the development of distributed solar PV faces challenges such as access to financing and rooftop space. To overcome these obstacles, a highway-operating company in Jinan, Shandong Province, has installed solar PV systems in open spaces along highways, roundabouts, and near tunnel exits, as well as on rooftops of toll stations and rest areas. The electricity produced is then sold to the state power grid.

China is also investing in wind power, with the world's biggest investment in this area. This is in addition to the country's efforts to reduce coal consumption through improved energy efficiency. For example, the Innovative Financing for Air Pollution Control in Jing-Jin-Ji Program financed the installation of two heat recovery units and a 21-kilometer heat pipeline in Datong, China's largest coal producer.

The World Bank has played a significant role in supporting China's transition to clean energy. The Innovative Financing for Air Pollution Control Program, supported by the World Bank, has financed investments in energy efficiency, renewable energy, and emissions control. This program has leveraged funding 5.4 times the original loan amount, with the International Bank for Reconstruction and Development (IBRD) providing a loan of $500 million. The Global Environmental Facility (GEF) has also provided a grant to enhance the implementation of the program.

China's efforts to embrace clean energy are making a notable impact. The country has reduced carbon dioxide emissions by an estimated 2.5 million tons annually, contributing to the return of blue skies in the Jing-Jin-Ji region. Additionally, China's battle against air pollution is expected to increase the average life expectancy of its citizens by 2.4 years if the declines in air pollution are sustained.

Reducing coal consumption

China's heavy reliance on coal to meet its energy demands has made it the single largest source of air pollutants and greenhouse emissions in the country. In 2014, China's coal consumption reached almost 1.8 billion tons, accounting for 40% of the country's total coal consumption and 66% of its energy mix. This escalating reliance on fossil fuels significantly contributes to air pollution, with coal production and thermal power generation increasing in regions failing to meet PM2.5 standards.

To reduce coal consumption, China has implemented several measures. Firstly, the government prohibited the construction of new coal-fired power plants and shut down several old plants in highly polluted regions, including the city clusters of Beijing-Tianjin-Hebei. This region, also known as Jing-Jin-Ji, experienced severe air pollution, with annual average PM2.5 concentrations far exceeding national and World Health Organization standards.

Secondly, China has invested in renewable energy sources such as wind and solar power. The country is rolling out the world's biggest investment in these sectors, aiming to replace coal as an energy source. For example, in Shandong Province, a highway-operating company has installed distributed solar PV systems along highways, in roundabouts, and near tunnel exits, selling the generated electricity to the state power grid.

Thirdly, China has focused on improving energy efficiency. The Innovative Financing for Air Pollution Control in Jing-Jin-Ji Program, supported by the World Bank, has financed investments in energy efficiency projects, such as the installation of heat recovery units and heat pipelines in China's biggest coal producer, Datong.

Finally, China has embraced transparency in its war on pollution, with the government declaring a comprehensive commitment to tackling the issue. This has included the introduction of aggressive afforestation and reforestation programs, such as the Great Green Wall, which has seen the planting of over 35 billion trees across 12 provinces.

Through these measures, China aims to reduce its coal consumption, improve air quality, and mitigate climate change.

Promoting electric vehicles

China has implemented various measures to combat its air pollution crisis, which has caused an estimated 1.1 million premature deaths annually. One key strategy has been the promotion of electric vehicles (EVs) to reduce emissions from traditional cars, which contribute to harmful ground-level ozone formation.

To encourage the adoption of electric vehicles, China has offered generous subsidies to EV buyers, reducing the cost of purchasing these vehicles. This initiative has been particularly successful, with China leading the world in EV sales and production. The country sold around 2.3 million electric vehicles in 2021, a year-on-year increase of 140%. This trend is set to continue, with the Chinese government setting a target of 30% of new car sales being electric or plug-in hybrid by 2025.

In addition to subsidies, China has also invested in EV charging infrastructure. The government has supported the development of a nationwide network of charging stations, making it more convenient for EV owners to recharge their vehicles. This network includes both fast-charging stations for long-distance travel and slower charging points in residential areas and parking lots.

Another strategy to promote electric vehicles has been the establishment of EV manufacturing hubs. China is now home to several major EV production bases, including those of global automakers like Volkswagen and Tesla. These hubs benefit from government incentives, such as tax breaks and preferential policies, to encourage further investment in the industry.

The Chinese government has also implemented policies to encourage the development of new energy vehicles (NEVs), which include electric vehicles, plug-in hybrids, and fuel cell electric vehicles. The NEV mandate, introduced in 2019, requires automakers to produce a set proportion of NEVs as part of their total output. This policy has driven innovation and competition in the EV market, with companies racing to meet the demand for more sustainable transport options.

Finally, China has also focused on raising awareness and educating the public about the benefits of electric vehicles. This has included campaigns highlighting the environmental and health advantages of EVs, as well as test-drive events and promotions to encourage people to experience the performance and cost-effectiveness of these vehicles firsthand.

By implementing these comprehensive measures, China has made significant progress in promoting electric vehicles as a solution to its air pollution crisis.
