China's Air Pollution: Strategies For A Cleaner Future

China has implemented various measures to combat its air pollution crisis, which has caused a public health emergency, killing over 1.1 million people annually and resulting in substantial economic losses. In 2013, China declared a war against pollution, allocating significant resources to address this issue. Since then, China has made notable progress, with pollution levels decreasing by 39.6% from 2013 to 2020, leading to substantial improvements in life expectancy for its citizens. This paragraph introduces the topic of China's efforts to reduce air pollution, highlighting the urgency, actions taken, and the positive impact on public health and the environment.

Reduce coal consumption

China, the world's largest coal producer and consumer, has taken several steps to reduce coal consumption and combat air pollution. Here are some measures China can focus on to further reduce coal consumption:

Transition to Clean Energy Sources

China has been actively transitioning from coal to cleaner energy sources, such as renewables and nuclear power. This shift is crucial for achieving global decarbonization and reducing air pollution. China's coal consumption has been declining since its peak in 2013, with a 3.7% drop in 2015, marking the second consecutive year of falling coal usage. This reduction in coal consumption is aligned with China's goal to peak carbon dioxide (CO2) emissions by 2030.

Strong Air Pollution Policies

China has implemented strict air pollution policies, requiring the most polluted regions to reduce their coal consumption. These policies have led to significant improvements in air quality. For example, between 2013 and 2017, Beijing reduced its atmospheric particulate matter (PM2.5) levels by 33%.

Rebalancing the Economy

China's government is rebalancing the economy away from heavy industry, which relies heavily on coal, towards services, higher technology manufacturing, and less carbon-intensive sectors. This structural shift is contributing to the decline in coal consumption and associated CO2 emissions.

Improving Energy Efficiency

China has been working to improve energy efficiency and reduce energy intensity. This includes implementing measures such as closing backward mines, aiding workers, and capping coal output and power capacity.

Canceling Coal Projects

China has been canceling planned coal projects due to overcapacity and air pollution concerns. In 2019 alone, they canceled more than 130 GW of planned coal projects.

International Partnerships

Forming international partnerships and coalitions can help China share strategies, experiences, and best practices with other countries undergoing similar transitions. This collaboration can accelerate the global shift away from coal and provide support for a just transition.

Addressing Social Justice Issues

Transitioning away from coal also involves addressing social justice issues, particularly the impact on employment and local tax revenues in coal-dependent regions. China has implemented policies to provide financial support, retraining, and employment assistance to affected workers in the coal industry.

By implementing these measures and continuing its commitment to reducing coal consumption, China can make significant strides in its battle against air pollution.

Increase natural gas production

China has been taking steps to reduce its air pollution, which has been a public health crisis, killing more than 1.1 million people annually. In 2013, China experienced some of its highest pollution levels, and public awareness and criticism reached new heights. As a result, the Chinese government declared a "war against pollution", implementing various measures to combat the issue. One of the critical strategies has been to increase natural gas production and reduce reliance on coal, which is the dirtiest and most polluting energy source.

China's central government and its state-owned oil and gas companies actively support the development of domestic natural gas resources. The conversion of coal heating to natural gas is a vital part of the government's strategy to reduce air pollution, particularly in northern China. Natural gas has the potential to provide climate benefits if it substitutes coal, and methane emissions are controlled.

In recent years, natural gas consumption in China has grown significantly. During the 13th Five-Year Plan (2015-2020), China's natural gas use increased by 70%. In 2021, China was the world's third-largest consumer of natural gas, and it accounted for 8.6% of the country's primary energy use. Approximately 6.5% of China's energy-related CO2 emissions came from natural gas. To ensure supply security and operational flexibility, the Chinese government has set targets for domestic natural gas production and aims to increase reserves and output of conventional and unconventional gas sources.

The government has also promoted natural gas consumption as a means of displacing dispersed coal in industrial, commercial, and residential use. However, the availability and cost of natural gas have been limiting factors. To address this, the government has amended policies to allow switching from dispersed coal to coal-powered electric stoves and coal-to-electricity, as long as it eliminates small industrial coal-fired steam boilers. The main priority remains to reduce pollution from fine particulate matter (PM2.5).

The increased adoption of natural gas has substantially reduced urban air pollution in major cities like Beijing, which was once notorious for its apocalyptic, smog-filled skies. By switching from coal to natural gas, Beijing has been able to reduce local coal production while maintaining energy access. The city has shut down over 2 gigawatts (GW) of local coal plant capacity and opened nearly 6 GWs of cleaner natural gas capacity. As local demand for natural gas rose, Beijing sourced more supplies from abroad, particularly through the Central Asia-to-China Pipeline (CACP).

While China's efforts to increase natural gas production and reduce air pollution have shown positive results, there are still challenges to address. China's victory over urban air pollution has come at a cost, as the government has often simply transferred coal generation from big cities to less populated locations. As a result, while urban air pollution has declined, China's emissions from steam coal used to generate electricity have risen by 28% since 2010. Additionally, China's natural gas production and imports must be balanced with the need to control methane emissions, as methane has a significant warming impact on the atmosphere.

Promote electric vehicles

China has already taken steps to promote the use of electric vehicles, with large cities like Shanghai, Shenzhen, and Guangzhou introducing all-electric bus fleets. Electric vehicles (EVs) are an important part of sustainable transportation and can be a cost-effective way to reduce operating expenses. They are also much cleaner than conventional vehicles, producing zero tailpipe emissions and reducing a fleet's greenhouse gas emissions.

Cost-Effectiveness

EVs can be cheaper to run than conventional cars, with electricity being a more affordable fuel source than gasoline. In the United States, for example, electricity costs an average of 10 cents per kilowatt-hour, which equates to about 3 cents per mile for an electric car, compared to 10 cents per mile for a gasoline car. This fuel efficiency can help reduce operating expenses, especially for businesses with large fleets.

Environmental Benefits

The main benefit of EVs is their environmental impact. By eliminating exhaust, EVs can significantly reduce a vehicle's greenhouse gas emissions, helping to improve air quality. This is particularly important in highly polluted cities like Beijing, where air pollution has caused a public health crisis, killing over 1.1 million people every year.

Fuel Sources

It is important to note that the environmental benefits of EVs depend on the energy sources used to generate the electricity that powers them. In areas that use low-polluting energy sources, EVs have a significant advantage over conventional vehicles. However, in areas that rely on higher-emissions electricity, such as coal-powered plants, the environmental benefits may be less significant. Nevertheless, even in coal-reliant countries like China, the use of electric cars has led to a 20% decrease in greenhouse gas emissions.

Battery Production

One potential drawback of EVs is the production of their batteries, which can be harmful to the environment if not done responsibly. The manufacturing process can create upstream emissions, particularly if inconsistent energy sources are used. However, this is already beginning to change, with EV manufacturers setting guidelines for their battery suppliers to use renewable energy sources. As a result, today's EV batteries have a much lower carbon footprint than those produced just a few years ago.

Promoting the use of electric vehicles can be an effective strategy for China to reduce air pollution. EVs offer both economic and environmental benefits, and with the right policies and infrastructure in place, China can further encourage their adoption, helping to improve air quality and reduce the health risks associated with air pollution.

Improve public transport

Improving public transport is a key strategy for reducing air pollution in China. Here are some ways China can enhance its public transportation system to mitigate air pollution:

Expand and electrify bus fleets: China can continue to expand and electrify its bus fleets, which have already seen significant progress. Electric buses emit less than half the carbon of gas-powered cars per passenger-kilometre travelled. By investing in more electric buses and transitioning away from diesel or fossil fuel-powered buses, China can significantly reduce air pollution and associated health risks, particularly in densely populated urban areas.

Increase vehicle occupancy: Encouraging a shift from private cars to buses and improving vehicle occupancy rates can help reduce emissions and air pollution. This can be achieved through incentives, such as discounted fares or priority lanes for buses, or disincentives for private car use, such as congestion charges or parking fees.

Promote active travel: In conjunction with improving public transport, China can encourage active travel options such as walking and cycling. This can be achieved by developing pedestrian and bicycle-friendly infrastructure, such as dedicated lanes and pathways, making it safer and more convenient for people to choose these environmentally friendly modes of transportation.

Integrate renewable energy sources: China can further reduce emissions by powering its electric public transport systems with renewable energy sources, such as solar or wind power. This will make electric public transport even more environmentally friendly and sustainable, reducing the country's reliance on fossil fuels.

By implementing these strategies, China can significantly improve its public transport system, reduce air pollution, and improve the health and well-being of its citizens.

Encourage afforestation

China has been taking steps to combat air pollution, and one of their strategies includes aggressive afforestation and reforestation programs. Afforestation is the process of establishing a forest on land that was not previously forested. China has already made progress in this area by planting more than 35 billion trees across 12 provinces through initiatives like the Great Green Wall.

Encouraging afforestation can be an effective strategy for China to reduce air pollution for several reasons. Firstly, forests act as carbon sinks, absorbing carbon dioxide (CO2) from the atmosphere and reducing greenhouse gas emissions. This is particularly important in mitigating the effects of climate change, as deforestation has been a significant contributor to the increased presence of CO2 over the past two centuries.

Secondly, trees and forests remove air pollutants through the interception of particulate matter on their surfaces and the absorption of gaseous pollutants through their leaves. This improves air quality and has a positive impact on human health, reducing mortality and respiratory issues. In the United States, for example, trees and forests removed approximately 17.4 million tonnes of air pollution in 2010, with health benefits valued at $6.8 billion.

Additionally, afforestation can help address other environmental issues such as barren land and soil erosion. Research from Crowther Lab suggests that an additional 25% of forested area could absorb 25% of atmospheric carbon, significantly impacting global temperatures.

To maximize the impact of afforestation initiatives, it is important to utilize green energy and engage the public. China can build on its existing efforts by continuing to invest in large-scale tree-planting programs and encouraging community participation in reforestation projects. This two-pronged approach will help reduce air pollution and contribute to the country's goal of improving air quality.
