China's Battle Against Air Pollution: Strategies And Challenges

Air pollution in China has been a significant issue for decades, causing a public health crisis and killing more than a million people every year. In response, the Chinese government has implemented various measures to tackle this problem. This includes the introduction of the Air Pollution Action Plan in 2013, which aimed to reduce PM2.5 levels and tighten rules governing vehicle exhausts. China has also invested heavily in afforestation and reforestation programs and worked with international organizations like the World Bank to secure funding and expertise for its pollution control efforts. While China has made notable progress in improving its air quality, it still has a long way to go to reach the World Health Organization's recommended annual average PM2.5 levels.

China's air pollution control programs

China has implemented a series of air pollution control programs to tackle its poor air quality, which has caused a public health crisis, killing more than 1.1 million people annually and costing the economy $37 billion in crop failure alone.

In 2013, the State Council issued the Air Pollution Prevention and Control Action Plan, which was supported by a $500 million loan from the World Bank. This action plan focused on reducing PM2.5 levels in key city clusters such as Beijing-Tianjin-Hebei and the Pearl and Yangtze Deltas. The plan also targeted a reduction in ground-level ozone, a highly irritating gas created by volatile organic compounds (VOCs) reacting with nitrogen oxides from vehicles.

To support the implementation of the Action Plan, the Innovative Financing for Air Pollution Control in Jing-Jin-Ji Program was introduced. This program aimed to improve energy efficiency, expand clean energy, and reduce air pollutants and carbon emissions. For example, the Wangping Power Company in Datong installed heat recovery units and a heat pipeline, eliminating the need for small polluting coal boilers and significantly reducing emissions.

China has also focused on afforestation and reforestation programs, such as the Great Green Wall, which involved planting over 35 billion trees across 12 provinces. These programs have seen investments of over $100 billion, exceeding the forestry expenditure per hectare of the US and Europe.

Other measures to combat air pollution include fitting scrubbers to coal power plants, tightening vehicle exhaust rules, and replacing coal with natural gas. China also aims to boost the share of new energy vehicles and machinery in airports, ports, and logistics parks.

Reducing coal consumption

China has been taking steps to reduce its coal consumption and combat air pollution. In 2013, the Chinese government introduced the Air Pollution Action Plan, which aimed to improve air quality and reduce pollution levels. As part of this plan, the government 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.

To further reduce coal consumption, China has invested heavily in renewable energy sources. In 2017, China spent $90 billion on renewable energy, surpassing the US as the largest investor. This investment has driven the rapid growth of China's renewables sector, with the country now boasting the world's largest installed base of wind power capacity and the second-largest solar power capacity.

China has also implemented policies to improve energy efficiency in the industrial and building sectors. By increasing energy efficiency and transitioning to cleaner energy sources, China aims to reduce its reliance on coal and decrease greenhouse gas emissions.

In addition to government initiatives, public pressure has played a significant role in China's efforts to reduce coal consumption. The documentary film "Under the Dome" sparked widespread concern about air pollution and the role of coal and petrochemical companies. This growing public awareness has influenced the government's agenda, with policies such as the Innovative Financing for Air Pollution Control in Jing-Jin-Ji Program addressing air pollution and promoting clean energy financing.

Despite these efforts, China continues to face challenges in reducing its coal consumption. In 2021, China announced the construction of 43 new coal power units, and in 2022, its increasing coal capacity offset global reductions. However, China has pledged to end financing for overseas coal power plants and is taking steps towards reducing its reliance on fossil fuels. President Xi Jinping announced that China will start phasing down coal use from 2026, demonstrating the country's commitment to addressing air pollution and mitigating climate change.

Improving energy efficiency

China has been taking steps to improve energy efficiency and reduce air pollution. Energy generation is one of the greatest sources of air pollution, and the rapid increase in the number of motor vehicles and the large share of coal-based electricity generation have made air pollution a particularly serious issue in China.

The Chinese government has implemented various measures to improve energy efficiency and reduce air pollution, including:

Green buildings are designed, constructed, and operated with energy-efficient principles in mind. For example, putting windows where the sun shines on a building in the winter can provide natural heat and reduce the need for heating with fossil fuels. Mandatory building standards and retrofits that reduce energy consumption within buildings can also help to reduce the need for power generation.

Scaling up the use of energy-efficient appliances and lighting

This reduces the demand for electricity generation and, therefore, reduces air pollution. Energy-efficient appliances and lighting can help to reduce energy consumption and associated pollution.

Transport was responsible for 28% of total final energy consumption globally in 2016, and more than 90% of transport energy use depends on oil products. Improvements in transport efficiency, such as mandatory vehicle fuel efficiency standards, can significantly reduce pollution within cities and have a positive impact on human health.

Reducing coal consumption and expanding clean energy

China has prohibited new coal-fired power plants and shut down old plants in polluted regions. By improving energy efficiency in the industrial and building sectors and increasing the supply of renewable energy, China can reduce coal consumption and associated air pollution.

Investing in renewable energy

China has invested in renewable, alternative forms of energy, such as solar power, to reduce air pollution. Renewable energy plants produce power from natural sources and require less investment to maintain than traditional power plants.

Implementing air pollution control programs

China has implemented various programs to control and reduce air pollution, such as the Air Pollution Control Action Plan and the Innovative Financing for Air Pollution Control in Jing-Jin-Ji Program, with a focus on improving energy efficiency and expanding clean energy.

These measures have helped China make significant progress in reducing air pollution and improving air quality. However, it is important to note that the rapid reduction in air pollution in China has also contributed to an increase in global warming, as the aerosols previously emitted were cooling the planet.

Investing in clean energy

China has been investing in clean energy to reduce air pollution and combat climate change. The country has set ambitious goals to peak carbon emissions before 2030 and achieve carbon neutrality before 2060. In 2023, China demonstrated its commitment to these goals by commissioning a record amount of solar PV capacity and significantly increasing its wind and nuclear power generation.

China's clean energy investments have been focused on several key areas. Firstly, the country has been promoting the development and adoption of renewable energy sources, such as solar power and wind energy. This includes providing financing for distributed solar PV systems for both rural households and businesses. Secondly, China has been investing in electric vehicles (EVs) and the necessary infrastructure, with exports of EVs and related technologies jumping by 30% in 2023 compared to the previous year. Thirdly, China is focusing on improving energy efficiency in industries and buildings, with investments in this sector reaching an estimated 0.6 trillion yuan in 2023. This includes the development of "green buildings", with a target of 80 million square meters per year of energy-efficient renovated or newly constructed buildings.

China has also been working to reduce air pollution emissions through various abatement measures. This includes installing equipment to remove particulate matter, implementing flue gas desulfurization and denitrification technologies, and replacing coal with natural gas. In addition, China has shut down several old coal-fired power plants in highly polluted regions and prohibited the construction of new ones.

To support these initiatives, China has leveraged green financing and international cooperation. The Innovative Financing for Air Pollution Control Program, supported by the World Bank, has provided financing for investments in energy efficiency, renewable energy, and emissions control. Additionally, the International Bank for Reconstruction and Development (IBRD) has provided loans, while the Global Environmental Facility (GEF) has offered grants to enhance results measurement and innovative financial product development.

While China's efforts to reduce air pollution have been commendable, there are still challenges to overcome. Coal remains a significant part of China's energy mix, and the country continues to invest in fossil fuel projects. Balancing the need for energy security with the transition to cleaner energy sources will be crucial for China's long-term success in addressing air pollution and mitigating climate change.

Reducing air pollution emissions

China has implemented a variety of measures to reduce air pollution emissions, with a particular focus on tackling emissions from coal power plants and vehicles.

In the early 2000s, China faced intense public scrutiny over its poor air quality, which was largely a result of rapid industrialisation. In response, the Chinese government took several actions to curb emissions from coal-fired power plants, including fitting scrubbers to reduce sulphate emissions and tightening rules governing vehicle exhausts. These measures led to a significant 75% drop in sulphate emissions.

To further combat air pollution, China introduced the Air Pollution Action Plan in 2013, which aimed to improve air quality in key cities like Beijing, Tianjin, and Hebei. This plan targeted a reduction in PM2.5 levels, which are fine particulate matter concentrations that pose significant health risks. The plan was successful, reducing PM2.5 levels in Beijing by 33% and in the Pearl River Delta by 15%.

China has also addressed ground-level ozone pollution, a highly irritating gas created by the reaction of volatile organic compounds (VOCs) and nitrogen oxides from vehicles. The new action plan introduced targets for reducing emissions of VOCs and nitrogen oxides by 10% and 15%, respectively, by 2020.

Additionally, China has invested in afforestation and reforestation programs, planting over 35 billion trees across 12 provinces. These initiatives, such as the Great Green Wall, have helped improve air quality and contributed to China's environmental efforts.

To finance these environmental initiatives, China has sought support from international organisations like the World Bank and the International Bank for Reconstruction and Development (IBRD). These institutions have provided loans and grants to promote clean energy financing and support the implementation of air pollution control programs.
