China's Air Pollution Crisis: The Human Cost

China's rapid economic development has come at a cost: air pollution. As the world's largest emitter of greenhouse gases, China's air pollution has caused a public health crisis, killing over 1.1 million people annually and costing the economy $37 billion in pollution-induced crop failure. The root causes of this crisis are multi-faceted, including a shift from bicycles to cars, rapid economic growth, population increase, and surging vehicle numbers. Despite these challenges, China is taking steps to combat air pollution, with Beijing, in particular, making remarkable strides to improve its air quality.

China's shift from bicycles to combustion engines

In the 1980s and 1990s, bicycles were the primary mode of transportation in Chinese cities like Beijing. In 1993, 76% of road space in Beijing was taken up by bicycles, and one in every two people owned a bicycle. However, by the early 2000s, the number of cars in Beijing had surged, with a 445% increase in car ownership between 1990 and 2000. This shift towards combustion engines was driven by China's rapid economic growth, population increase, and increasing affordability of cars.

The consequences of this shift were dire. The surge in vehicles, coupled with other factors, severely degraded Beijing's air quality, earning it a reputation for being shrouded in smog. The air pollution caused by combustion engines contributed to a public health crisis, with more than 1.1 million people dying annually due to air pollution in China. The economy also suffered, with an annual loss of $37 billion due to pollution-induced crop failure.

Recognizing the severity of the problem, the Chinese government has taken significant steps to combat air pollution in recent years. Beijing, in particular, has made remarkable strides in improving its air quality. The city has implemented various initiatives, including Low Emission Zones (LEZs) that restrict access for polluting vehicles, driving the adoption of cleaner modes of transportation. Beijing has also introduced license plate lotteries, driving bans, and incentives for scrapping older vehicles, signaling its commitment to phasing out polluting cars.

In addition to these measures, China is actively promoting the use of electric vehicles (EVs) and new energy vehicles (NEVs) to reduce carbon emissions. The production and sale of EVs and NEVs have exploded in China, with the country now accounting for more than half of all new electric cars sold worldwide. The government has provided tax incentives, such as exemptions from the Vehicle Purchase Tax, to encourage the uptake of NEVs. These efforts reflect China's recognition of the environmental and health benefits of reducing reliance on combustion engines and its commitment to fostering a greener and more sustainable future.

The country's economic progress

China's economic progress has come at a cost to the environment, with air pollution causing a public health crisis. The country's rapid economic growth, population increase, and surging number of vehicles have put immense pressure on the environment, particularly air quality. The economic development has led to a shift from bicycles to combustion engines, creating a complex web of challenges. The increase in individual wealth has contributed to a deterioration in air quality as more people can afford cars. This has resulted in a sharp increase in vehicles on the roads, with Beijing's vehicle population growing by 335% between 1998 and 2017.

China's emergence as the world's largest automobile producer and consumer has had detrimental effects, including increased oil consumption. The country's dramatic economic growth has also led to urbanisation, with people moving from bicycles to cars, further contributing to air pollution. The government's focus on economic progress has resulted in industrial sites and power plants that contribute to air pollution.

However, China has also made significant strides in addressing air pollution and improving air quality. The country has implemented various policies and initiatives to reduce emissions and promote cleaner modes of transportation. Beijing, in particular, has made remarkable progress, setting an example for other cities. The city has introduced Low Emission Zones (LEZs), driving the adoption of cleaner, emission-compliant modes of transportation. Stringent emission standards and incentives for new energy vehicles (NEVs) have also been put in place.

China is also promoting the use of electric vehicles and expanding funding for clean heating. The government has invested in afforestation and reforestation programs, planting billions of trees across provinces. Additionally, China has received support from international organisations like the World Bank and the International Bank for Reconstruction and Development (IBRD) to finance its air pollution control programs.

While China's economic progress has contributed to air pollution, the country is taking steps to mitigate its impact and improve air quality through policy changes, technological advancements, and investments in sustainable initiatives.

Population increase

China's rapid economic growth, population increase, and surging number of vehicles have put immense pressure on the country's environment, particularly its air quality. Beijing, for instance, has been shrouded in smog and has struggled with severe air pollution.

Over the past two decades, Beijing's GDP, population, and number of vehicles have sharply increased by 1078%, 74%, and 335% respectively. As China emerged as the world's largest automobile producer and consumer, it struggled with the detrimental impacts of increased oil consumption.

Population density has been shown to have a significant impact on air pollution in China. As the population in urban areas continues to grow, the demand for energy and transportation increases, leading to higher emissions and pollution levels. This phenomenon, known as the "mortality penalty", results in higher death rates in urban areas compared to rural areas due to the concentration of pollutants.

However, some studies have suggested that an increase in population density can also lead to improved air quality. This is because a higher population density can lead to increased demand for clean energy and public transportation, reducing the unit cost and increasing consumption. Additionally, with more people concentrated in specific areas, the implementation of emission control measures and clean energy initiatives can become more feasible and effective.

To tackle air pollution, China has implemented various measures, including aggressive afforestation and reforestation programs, such as the Great Green Wall, which has helped reduce sandstorms in Beijing. The country has also invested in electric vehicles and promoted the use of public transportation, with cities like Shanghai, Shenzhen, and Guangzhou restricting the number of cars on the road.

Poor air quality policies

China's rapid economic growth, population increase, and surging number of vehicles have put immense pressure on the country's environment, particularly its air quality. While China has lifted millions out of poverty, the price of this progress is demonstrated in the air pollution that has caused a public health crisis, killing more than 1.1 million people annually.

Beijing, in particular, has struggled with severe air pollution, with economic growth, urbanisation, and increases in individual wealth contributing to a deterioration in air quality. The Chinese government has implemented various policies to address this issue, including the Air Pollution Action Plan released in 2013, which helped the nation significantly improve its air quality between 2013 and 2017.

However, critics argue that China's policies have not gone far enough to address the country's poor air quality. Here are some examples of policies that have been criticised for falling short:

• Lack of Comprehensive Air Quality Standards: While China has set targets for reducing particulate matter (PM2.5) and ground-level ozone, it has yet to adopt comprehensive air quality standards that address all major pollutants. This piecemeal approach may hinder the effectiveness of their policies.
• Insufficient Emission Reduction Targets: China's emission reduction targets have been criticised for not being ambitious enough. For example, the target of reducing PM2.5 levels by 18% in 231 cities is a positive step, but it still falls short of the World Health Organization's recommended annual average of 10µg/m³.
• Inadequate Enforcement of Vehicle Emission Standards: Beijing has implemented Low Emission Zones (LEZs) and incentivised the adoption of electric vehicles. However, enforcement of emission standards for diesel trucks and older vehicles remains a challenge, with many polluting cars still on the road.
• Limited Focus on Industrial Emissions: While China has targeted coal-fired power plants and industrial sites for closure, there is a need for more comprehensive policies to reduce industrial emissions. This includes addressing the root causes of high energy consumption and high-emission projects.
• Lack of Regional Coordination: China's air pollution policies are often implemented at the city or provincial level, leading to a lack of coordination between regions. This can result in inconsistent standards and loopholes that hinder overall progress.
• Insufficient Investment in Green Technologies: China has made strides in investing in green technologies and renewable energy sources, but more needs to be done. Critics argue that China should further incentivise and subsidise the development and adoption of clean energy technologies to reduce carbon emissions and improve air quality.

High emissions from vehicles

China's rapid economic growth, population increase, and surging number of vehicles have put immense pressure on the country's environment, particularly its air quality. As the world's largest automobile producer and consumer, China has been grappling with the detrimental impacts of increased oil consumption. The combustion of gasoline or diesel fuel in vehicle engines produces a variety of harmful chemical emissions, such as CO, HC, NOx, and PM, which have remained at high levels for many years. The huge number of on-road vehicles in China consumed 95 million tons of gasoline and 172 million tons of diesel in 2013, and the number is predicted to continually rise with increasing car sales.

Beijing, in particular, has been struggling with severe air pollution, with its GDP, population, and number of vehicles increasing sharply by 1078%, 74%, and 335% respectively between 1998 and 2017. To tackle this issue, Beijing has implemented a range of policies, including license plate lotteries, driving bans, and incentives for scrapping older, polluting vehicles. The city has also introduced Low Emission Zones (LEZs), which restrict access for polluting vehicles and drive the adoption of cleaner, emission-compliant modes of transportation.

China has also taken steps to promote the use of electric vehicles to reduce carbon emissions, aiming to have fast-charging stations at no less than 80% of highway service areas in key regions by 2025. Additionally, the government has called for increasing freight cargo transport by rail and water to reduce higher-polluting road transport. These initiatives are part of China's efforts to improve air quality and address the public health crisis caused by air pollution, which kills more than 1.1 million people every year.

While China has made significant progress in reducing vehicle emissions and improving air quality, there are still challenges to be addressed. The country's rapid urbanization, with approximately 14 million people moving from rural to urban areas each year, contributes to the growing number of vehicles on the road. Furthermore, regional differences in fuel quality and poor road system design impact air pollution levels. To effectively manage vehicle-induced air pollution, an integrated strategic control approach is necessary, incorporating social participation, technical revolution, and regulatory innovation.
