China's War On Air Pollution

China's rapid economic growth has historically been fuelled by fossil fuels, resulting in severe air pollution. The country has been taking steps to address this issue, with a particular focus on reducing emissions from coal-fired power plants and improving air quality in its cities. China's efforts to combat air pollution have included implementing national action plans, investing in afforestation and reforestation programs, promoting the use of electric vehicles, and reducing coal consumption. These measures have led to significant improvements in air quality and are expected to have a positive impact on the country's life expectancy. China's actions have also reduced transboundary air pollution, benefiting neighbouring countries such as South Korea.

Reducing PM2.5 levels

China has implemented various measures to reduce PM2.5 levels, a primary component of air pollution, which has resulted in significant improvements in air quality.

One key strategy has been the introduction of aggressive afforestation and reforestation programs, such as the Great Green Wall, which involved planting more than 35 billion trees across 12 provinces. This initiative, backed by investments of over $100 billion, played a crucial role in reducing PM2.5 levels.

China has also focused on transitioning away from fossil fuels, particularly coal, which has been a major contributor to air pollution. The government prohibited the construction of 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. China aims to reduce coal consumption in these regions and others by about 10% from 2020 levels by 2025.

In addition, China is promoting the use of electric vehicles to reduce carbon emissions. The government plans to establish fast-charging stations at no less than 80% of highway service areas in key regions, including Beijing, Tianjin, and Shanghai, by 2025. This push for electrification is expected to decrease PM2.5 levels significantly.

Another aspect of China's strategy is the development of new and clean energy sources. The country aims to increase natural gas production and support projects that contribute to overall grid safety and stability. Additionally, China intends to expand funding for clean heating in the northern regions and provide financial support for the modernization of traditional industries.

The implementation of these measures has resulted in notable improvements. Between 2013 and 2017, Beijing achieved a 33% reduction in PM2.5 levels, from 89.5 µg/m³ to 60 µg/m³, with an annual average of 58 µg/m³. While no cities reached the World Health Organization's recommended level of 10 µg/m³, the improvements in air quality are expected to have a positive impact on public health and life expectancy.

Reforestation programmes

China's environmental crisis, the result of decades of rapid industrialization, has had a detrimental impact on the health and livelihoods of its citizens. The country has been notorious for its bad air pollution, with carbon-intensive industries causing additional environmental challenges such as water scarcity and soil contamination.

China has taken significant steps to address its air pollution crisis, and one of the key strategies has been the implementation of reforestation programmes. Reforestation is a large-scale approach to removing CO2 from the atmosphere, helping China work towards its goal of carbon neutrality by 2060. China has invested heavily in such programmes, with expenditures exceeding $100 billion. The country has planted more than 35 billion trees across 12 provinces, and its forestry expenditure per hectare has exceeded that of the US and Europe.

One notable initiative is the Great Green Wall, which aims to create a protective belt of forests to combat desertification and soil erosion. The Grain for Green Programme, launched in 1999, is another important project. This programme incentivizes farmers to convert steeply sloped or ecologically fragile farmland into forests or grasslands by providing subsidies or compensation.

The Green Belt Development initiative targets urban areas, creating green belts and urban forests to improve air quality, mitigate the urban heat island effect, and provide recreational spaces for residents. China has also implemented a nationwide ban on felling natural forests between 2014 and 2017, and in 2020, the government revised the Forestry Law for the comprehensive Protection of Natural Forests.

These reforestation efforts have had a positive impact on China's air quality. According to the Global Burden of Disease study, the average PM2.5 concentration dropped by 50% from 2013 to 2019, resulting in the prevention of approximately 400,000 premature deaths annually. China's success in reducing pollution has contributed to a potential increase in average life expectancy for its citizens.

While China's reforestation journey is ongoing, these programmes demonstrate the country's commitment to improving air quality and mitigating climate change.

Reducing coal consumption

China is the world's largest consumer and producer of coal, with coal consumption and production accounting for more than half of the world's total in 2021. Coal combustion in China has been responsible for more than 20% of global CO2 emissions from fossil fuels annually for the past decade. As such, reducing coal consumption is a key part of China's air pollution reduction strategy.

China's energy regulator aims to reduce the share of coal in its total energy mix, with President Xi Jinping announcing that the country will start phasing down coal use from 2026. The 14th Five-Year Plan (2021-2025) will see the "strict control" of coal use, with a further phase-down during the 15th Five-Year Plan (2026-2030).

China has already implemented policies to reduce coal consumption, including capping coal use, removing dispersed coal from urban areas, switching from coal to natural gas heating, closing inefficient coal-fired boilers, and strengthening efficiency standards in power plants. The government has also prohibited new coal-fired power plants and shut down old plants in highly polluted regions.

To promote the use of renewable energy sources, China invested $90 billion in the sector in 2014, more than any other country. This has resulted in China having the world's largest installed base of wind power and the second-largest solar power capacity. Researchers at Harvard University and Tsinghua University predict that wind power could produce all of China's electricity at the price of coal by 2030. China also plans to expand funding for clean heating in the northern regions and increase credit and financing support for upgrading traditional industries.

In addition to renewable energy, China is also promoting the use of electric vehicles to reduce carbon emissions. By 2025, the government aims to have fast-charging stations at no less than 80% of highway service areas in key regions, including Beijing, Tianjin, and Shanghai.

Promoting electric vehicles

China has been taking several measures to combat air pollution, including promoting the use of electric vehicles (EVs) to reduce carbon emissions. The country aims to have fast-charging stations at a minimum of 80% of highway service areas in key regions, including Beijing, Tianjin, and Shanghai, by 2025. This is expected to reduce carbon emissions and improve air quality.

Electric vehicles have no tailpipe emissions, which means they do not emit any pollutants directly into the atmosphere. However, it is important to consider the emissions associated with generating the electricity used to charge EVs. These emissions depend on the energy source used to generate the electricity. For example, coal and natural gas emit carbon pollution, while renewable sources like wind and solar do not. Overall, research shows that electric vehicles are responsible for lower levels of greenhouse gas emissions than traditional gasoline-powered vehicles.

In addition to the environmental benefits, there are also economic incentives for promoting electric vehicles. The production and use of electric vehicles can create new jobs and stimulate economic growth. Additionally, the reduced dependence on oil can improve a country's energy security and reduce the economic burden of importing oil.

To encourage the adoption of electric vehicles, the Chinese government can offer subsidies or tax incentives for purchasing electric vehicles. They can also invest in the development of EV charging infrastructure, making it more convenient and accessible for people to charge their electric vehicles.

Furthermore, public education and awareness campaigns can play a crucial role in promoting electric vehicles. Educating the public about the environmental and health benefits of electric vehicles can help increase their popularity and encourage people to make the switch from traditional gasoline-powered cars. Overall, promoting electric vehicles is an important step in reducing air pollution and improving the environment in China.

Reducing emissions

China has implemented various measures to reduce emissions and improve air quality. One key approach has been the introduction of national air pollution action plans, which have significantly reduced pollution levels and associated health risks. These plans have included specific targets for reducing PM2.5 levels, which are fine particulate matter that can affect people's health. For example, the 2013 Air Pollution Action Plan helped China achieve a 33% reduction in PM2.5 levels in Beijing and a 15% reduction in the Pearl River Delta between 2013 and 2017.

China has also taken steps to address ground-level ozone pollution, a primary pollutant that was not included in the 2013 plan. Ozone is a highly irritating gas created by volatile organic compounds (VOCs) reacting with nitrogen oxides released from vehicles. By 2025, China aims to cut PM2.5 density by 10% compared to 2020 levels and keep the number of days with severe pollution to less than 1%.

To achieve these targets, China is promoting the use of electric vehicles and expanding the infrastructure for fast-charging stations. By 2025, at least 80% of highway service areas in key regions, including Beijing, Tianjin, and Shanghai, will have fast-charging stations, with at least 60% coverage in other regions. China is also working to increase freight cargo transport by rail and water, reducing reliance on higher-polluting road transport.

In addition to reducing emissions from transportation, China is taking measures to control coal use and curb high-emissions projects. The government has prohibited new coal-fired power plants and shut down old plants in highly polluted regions. By 2025, China aims to reduce coal consumption in the Beijing-Tianjin-Hebei region and surrounding areas by about 10% from 2020 levels. Similar targets have been set for other regions, such as the Yangtze River Delta and Shanxi and Shaanxi provinces.

China is also investing in afforestation and reforestation programs, such as the Great Green Wall, which has seen the planting of more than 35 billion trees across 12 provinces. These programs not only help reduce emissions but also contribute to carbon sequestration and overall ecological improvement.
