China's Battle Against Air Pollution

China has implemented various measures to combat its severe air pollution problem, which has caused a public health crisis, killing over 1.1 million people annually. Beijing, in particular, has been shrouded in smog, with economic growth, population increase, and a surge in vehicles contributing to poor air quality. To address this, China has introduced national air pollution action plans, targeting the reduction of PM2.5 levels and ground-level ozone, a highly irritating gas. The government has also focused on transitioning to cleaner energy sources, promoting electric vehicles, and investing in afforestation and reforestation programs. These efforts have shown positive results, with significant improvements in air quality and increases in life expectancy.

Reforestation and afforestation programmes

China has implemented aggressive afforestation and reforestation programmes, such as the Great Green Wall, which has seen over 35 billion trees planted across 12 provinces. With investments of over $100 billion in such programmes, China's forestry expenditure per hectare exceeded that of the US and Europe, becoming three times higher than the global average.

China's reforestation efforts are aimed at restoring ecosystems, combating soil erosion, and improving air and water quality. For example, in regions like the Kubuqi Desert, reforestation efforts have been targeted at combating desertification and reducing sandstorms. China has also been mobilising public and private funds to help conserve forests, reforming financial systems, and avoiding harmful investments that lead to deforestation.

The country has also implemented policies to support the global effort to reduce deforestation. At the CoP26 in Glasgow, China and the US made a joint statement recognising that ending illegal deforestation would contribute to the goals of the Paris Agreement. China has also been working on trials of conserving natural forests, with the Grain for Green Programme launched in 1999, which aimed to convert steeply sloped or ecologically fragile farmland into forests or grasslands. Farmers were given subsidies or compensation to stop cultivation on these lands, allowing them to turn to naturally regenerated forests.

China's reforestation efforts have positively impacted several industries by aligning them with sustainable practices. The renewable energy sector gains traction as reforestation underscores the need for cleaner alternatives to fossil fuels, providing an impetus for investments and advancements in solar, wind, and hydropower sectors. The cultivation and harvest of non-timber forest products, such as berries, mushrooms, and latex, become more viable as forest areas expand, diversifying income sources for local communities.

However, China's reforestation efforts have also revealed significant regional disparities in forest coverage, influenced by geographical factors. Provinces like Guangdong and Zhejiang stand out for their high forest coverage, closely linked to their economic prosperity and environmental preservation initiatives. In contrast, provinces such as Shandong, Jiangsu, and Henan exhibit lower forest coverage due to their primary role as grain-producing regions, requiring substantial land allocation for agricultural purposes.

Reducing coal consumption

China has implemented several measures to reduce coal consumption and combat air pollution. Here are some key initiatives and their impacts:

• China has set ambitious targets to reduce coal consumption in the Beijing-Tianjin-Hebei region and surrounding areas by approximately 10% from 2020 levels by 2025. This is expected to significantly improve air quality in this heavily polluted region.
• Railway usage for long-haul coal transport around key mining hubs in the northern and northwestern regions is targeted to reach 90% by 2025. This shift from road transport will help reduce emissions and improve air quality.
• The Chinese government has committed to "strictly and reasonably" controlling total coal use, recognizing that coal combustion is a significant contributor to air pollution and health issues.
• To achieve these goals, China is investing in the development of new and clean energy sources, such as renewable energy projects, and increasing natural gas production.
• The Innovative Financing for Air Pollution Control Program, supported by the World Bank and other financial institutions, has played a crucial role in providing financing for energy efficiency and renewable energy initiatives. This program has helped reduce carbon dioxide emissions by an estimated 2.5 million tons per year.
• China's efforts to curb coal consumption and transition to cleaner energy sources have had notable health benefits. Studies show that between 2013 and 2017, substantial reductions in mortality and years of life lost (YLL) related to air pollution were achieved, demonstrating the positive impact of these initiatives on public health.

Transition to electric vehicles

China has implemented various measures to control air pollution, including transitioning to electric vehicles (EVs). As a leader in electric mobility, China owns 99% of the world's 385,000 electric buses, with an expected increase to 600,000 by 2025. This shift has positively impacted the reduction of air pollution and greenhouse gas emissions.

In 2021, China mandated that electric vehicles make up 40% of all car sales by 2030, significantly impacting the global EV market. This transition is expected to reduce air pollution, improve public health, and enhance national energy security. To encourage EV adoption, some highly polluted Chinese cities began restricting license plates for internal combustion engine vehicles (ICEVs) and offering lower-cost "green car plates" for EVs, making them more cost-competitive.

However, the transition to EVs comes with challenges. Studies have shown that refining the critical minerals needed for EV batteries, such as nickel and cobalt, could create pollution hotspots near manufacturing hubs, particularly increasing sulfur dioxide (SO2) emissions. Additionally, in regions where coal-based electricity is prevalent, EVs may contribute to increased total and urban emissions of certain air pollutants, such as SO2 and PM.

To address these challenges, China needs to focus on developing and enforcing strict air pollution standards for the EV supply chain, including battery manufacturing, and transitioning to cleaner energy sources to power EVs. Despite these challenges, the transition to EVs in China is a crucial step towards improving air quality and mitigating climate change.

The Chinese government has also implemented other measures to control air pollution, including aggressive afforestation and reforestation programs, such as the Great Green Wall, and investing over $100 billion in such initiatives. Additionally, China has prohibited new coal-fired power plants and shut down old ones in highly polluted regions, aiming to reduce coal consumption and curb high-emission projects.

Scrapping old, polluting cars

China has implemented various measures to control air pollution, including scrapping old, polluting cars. This move is part of the country's efforts to improve air quality and reduce carbon emissions.

In 2014, China announced plans to remove up to six million vehicles that did not meet exhaust emission standards from the roads by the end of that year. This included scrapping 330,000 cars in Beijing, 660,000 cars in the surrounding province of Hebei, and 160,000 cars in Shanghai. The government also offered subsidies to car owners who voluntarily turned in their ageing vehicles for scrapping.

The following year, in 2015, the government planned to scrap up to five million more vehicles from other highly developed regions, including the Yangtze River Delta, the Pearl River Delta, and the Beijing-Tianjin-Hebei region. This was part of a wider action plan to strengthen control over vehicle emissions and promote energy savings, emissions reductions, and low-carbon development.

Beijing, in particular, has made significant strides in curbing vehicle emissions and promoting electric mobility. The city has reintroduced bike-sharing schemes and expanded its subway system to encourage alternative modes of transportation. Additionally, Beijing has pushed for the use of electric vehicles, with fast-charging stations planned for key regions by 2025.

By taking old, polluting cars off the roads and promoting more sustainable modes of transportation, China aims to reduce air pollution, improve public health, and meet its environmental targets. These efforts are part of the country's ongoing battle against air pollution and its commitment to improving the quality of life for its citizens.

Reducing emissions from diesel trucks

Emission Standards and Regulations:

China has tightened emission standards and introduced new guidelines specifically targeting diesel truck emissions. The country has developed diesel vehicle emission standards based on the European emission standard system, with the latest being the "China VI" standards implemented nationwide in 2021. These standards aim to reduce nitrogen oxide and particulate matter emissions from diesel trucks, and non-compliant new trucks are not permitted to enter the market.

Fuel Quality Improvement:

The Chinese government has committed to improving the quality of diesel fuel and cracking down on the use of low-grade fuel. This includes raising fuel standards and implementing the "China VI" fuel standards in key regions, helping to reduce overall emissions from fuel combustion.

Promoting Electric Vehicles:

China is actively promoting the use of electric vehicles, including electric buses, to reduce carbon emissions. By 2025, they plan to have fast-charging stations at a minimum of 80% of highway service areas in key regions like Beijing, Tianjin, and Shanghai. This shift towards electric mobility not only reduces emissions but also contributes to improving air quality.

Increasing Rail Freight Transport:

China aims to increase freight cargo transport by rail and water, reducing the reliance on higher-polluting road transport, especially diesel trucks. They plan to increase national rail freight rates and ensure that long-distance bulk commodity deliveries are primarily done via rail or ships. This strategy not only reduces emissions but also helps alleviate road congestion.

Vehicle Inspection and Monitoring:

The government has increased the frequency of inspections for diesel trucks to ensure they meet the required emission standards. They have also strengthened their monitoring capabilities to track and manage diesel truck emissions more effectively, utilizing remote online monitoring technology.

Traffic Flow Management:

To reduce the impact of diesel truck emissions on heavily populated areas, China has implemented measures to control the flow of truck traffic. This includes ordering lorries to use beltways to bypass densely populated regions, minimizing the exposure of residents to pollutants.

These measures demonstrate China's commitment to reducing emissions from diesel trucks and improving air quality for its citizens. By enforcing stricter standards, investing in electric mobility, and promoting alternative modes of transport, China is making significant strides in its battle against air pollution.
