China's Future: Reducing Pollution With Innovation

China has made significant progress in reducing pollution and improving air quality in recent years, but it continues to face challenges in its efforts to create a sustainable future. The country has implemented various measures, such as restricting coal use and promoting clean energy, to combat pollution and improve the health of its citizens.

China's rapid economic growth and industrialization have led to an increase in air pollution, causing a public health crisis with severe consequences. To address this issue, China has taken several steps, including restricting coal-fired power plants and promoting electric vehicles. The government has also invested in afforestation and reforestation programs, contributing to a significant reduction in particulate pollution.

In addition, China has embraced electric mobility, with cities like Shenzhen, Shanghai, and Hangzhou leading the way. The country owns 99% of the world's electric buses, and this number is expected to grow further.

However, China still has a long way to go to meet the World Health Organization's recommended air quality standards. The government has recognized this and continues to implement plans to tackle air pollution, such as the 2020 Action Plan, demonstrating its commitment to creating a cleaner and healthier environment for its citizens.

Electric vehicles

China has set ambitious goals for EV adoption, aiming to have 5 million EVs on the road by 2020 and over 80 million by 2030. To achieve these goals, China is transitioning from a subsidy-based approach to a combination of regulatory initiatives and stricter automobile efficiency standards. This includes a mandate requiring a certain percentage of vehicles sold by manufacturers each year to be battery-powered. As a result, it is expected that EVs will make up 40% of all car sales by 2030.

The development of affordable and accessible charging infrastructure is a major challenge in China's transition to EVs. The government is committed to ensuring the installation of fast-charging stations and charging units in parking lots, residential buildings, and office complexes. China is also subsidizing charging costs by keeping electricity tariffs low.

While EVs have the potential to reduce greenhouse gas emissions, the impact depends on the size of the vehicles and the coal intensity of the electric grid. Studies suggest that GHG emissions per 100 kilometers of driving for an EV in China will range from 10.44 to 17.94 kg of CO2 equivalent, compared to 18.24 kg for a gasoline-fueled vehicle. However, when considering the full lifecycle of EVs, including the emissions-intensive manufacturing process, the CO2 emission advantage of EVs decreases by about 36%.

Overall, China's efforts to promote EV adoption are expected to have a positive impact on reducing pollution and greenhouse gas emissions, particularly in highly populated areas with high vehicle ownership, such as the Beijing-Tianjin-Hebei region.

Reducing coal consumption

China's coal consumption and production account for more than half of the world's total. In 2021, coal consumption in China grew by almost 5% and reached its highest level ever. However, in the first half of 2022, coal consumption decreased by roughly 2-3% year-over-year. China uses more coal than the rest of the world combined, with roughly 54% of global consumption in 2021.

China has plans to "strictly control" coal use during the 14th Five-Year Plan period (2021–2025) and start phasing down coal use during the 15th Five-Year Plan period (2026–2030). In the 13th Five-Year Plan (2016–2020), China introduced many policies aimed at reducing coal's share of the energy mix, including capping coal use, removing dispersed coal from urban areas, and closing inefficient coal-fired boilers.

In 2018, China's State Council released a three-year action plan to cut coal consumption, boost electric vehicle sales, and shut down outdated steel and coke capacity. The plan also included targets to reduce coal consumption in the Beijing-Tianjin-Hebei region and the Yangtze River Delta region.

China has prohibited new coal-fired power plants and shut down a number of old plants in the most polluted regions. In addition, large cities like Shanghai, Shenzhen, and Guangzhou have restricted the number of cars on the road and started introducing all-electric bus fleets. China has also taken measures to tackle small-scale "scattered" pollution sources and cut off water, electricity, and raw material supplies to firms that violate rules.

China's efforts to reduce coal consumption and pollution are aligned with its goal to achieve carbon neutrality by 2060 and promote ecological civilization. The country has invested over $100 billion in aggressive afforestation and reforestation programs, such as the Great Green Wall, and planted more than 35 billion trees across 12 provinces.

Green financing

The People's Bank of China (PBOC), the country's central bank, has released statistics showing that outstanding green loans in China have so far exceeded 22 trillion yuan, about 10% of the country's total loan balance. The country's green bonds have also hit more than 2.5 trillion yuan, among the highest in the world.

Multiple banks have reported growing businesses in green credit, and their green financial products such as green bonds and green wealth management have been constantly enriched. For instance, the balance of green loans of the Industrial and Commercial Bank of China stood at 3.98 trillion yuan ($580 billion). The China Construction Bank has been working to advance green leasing, inclusive leasing, and digital upgrading, and the Bank of China has issued 87.7 billion yuan of green bonds.

To promote green and low-carbon economic and social development, the PBOC has launched a carbon-reduction supporting tool and a special re-lending program for supporting the clean and efficient utilization of coal to advance green development in a science-based manner. As of the end of 2022, the central bank had lent more than 300 billion yuan via the carbon-reduction supporting tool and helped banks lend 600 billion yuan to green projects, contributing to about 100 million tons of carbon reduction.

In June 2022, the China Banking and Insurance Regulatory Commission announced green finance guidelines, requiring banks and insurers to promote green finance at a strategic level, reduce the carbon intensity of their asset portfolios, and eventually achieve carbon neutrality. Banks and insurers should increase support for the green, low-carbon, and circular economy, prevent environmental, social, and governance risks, and include ESG requirements into their management processes.

Reducing emissions from diesel trucks

China has implemented various measures to reduce pollution and improve air quality. These include:

• Prohibiting new coal-fired power plants and shutting down old plants in highly polluted regions.
• Restricting the number of cars on the road in large cities and introducing all-electric bus fleets.
• Reducing iron and steel-making capacity and closing coal mines.
• Implementing aggressive afforestation and reforestation programs, such as the Great Green Wall, and planting billions of trees across several provinces.
• Introducing the Air Pollution Action Plan in 2013, which helped China achieve significant improvements in its air quality between 2013 and 2017.
• Launching the Three-year Action Plan for Winning the Blue Sky War in 2018, which mandates an 18% reduction in PM2.5 levels in 231 cities.
• Focusing on reducing ozone pollution by adding targets for both volatile organic compounds (VOCs) and nitrogen oxides emissions.
• Promoting the use of electric vehicles and expanding the use of rail and water transport for freight cargo to reduce emissions from road transport.

To reduce emissions from diesel trucks specifically, China can consider the following strategies:

Upgrading or Replacing Old Diesel Trucks

China can encourage the replacement of old, high-emitting diesel trucks with newer, cleaner models. This includes retrofitting or upgrading existing fleets with advanced emission control technologies, such as selective catalytic reduction (SCR) systems and diesel particulate filters (DPFs). By doing so, China can significantly reduce emissions of nitrogen oxides (NOx) and particulate matter (PM).

Promoting the Use of Alternative Fuels

China can incentivize the use of cleaner alternative fuels, such as ultra-low sulfur diesel (ULSD) and biodiesel blends. These fuels produce lower emissions compared to traditional diesel and can help reduce particulate matter, nitrogen oxides, and other pollutants.

Improving Fuel Efficiency and Engine Maintenance

China can implement programs to optimize fuel efficiency and promote regular engine maintenance for diesel trucks. This includes measures such as improved driving practices, fuel additives, and engine tuning. By optimizing fuel injection timing, using fuel additives to improve combustion, and ensuring proper maintenance, emissions can be reduced.

Implementing Idling Reduction Measures

Idling diesel engines contribute significantly to air pollution. China can encourage the use of auxiliary power units (APUs) or shore power for trucks instead of idling during rest periods. Additionally, implementing anti-idling policies and providing education on the environmental and economic impacts of idling can help reduce emissions.

Optimizing Routing and Traffic Flow

Optimizing truck routing and traffic flow can reduce emissions by minimizing congestion and idling time. China can invest in intelligent transportation systems, such as GPS-based routing and traffic management systems, to optimize the movement of goods and reduce unnecessary emissions.

Promoting Weight Reduction and Aerodynamic Improvements

Reducing the weight of diesel trucks and improving their aerodynamic characteristics can lead to fuel efficiency improvements and lower emissions. China can offer incentives for the use of lightweight materials and aerodynamic devices, such as trailer skirts and gap fairings.

Afforestation and reforestation

China has been at the forefront of reforestation efforts globally, and afforestation and reforestation are key components of its strategy to reduce pollution and achieve carbon neutrality by 2060. China's reforestation efforts are driven by the need for environmental restoration, combatting deforestation, desertification, and air and water pollution.

China has implemented several initiatives to promote afforestation and reforestation, including:

• The Three-North Shelterbelt Program: Launched in 1978, this program aims to enhance forestation and improve environmental conditions in northern China, spanning 13 provinces, autonomous regions, or municipalities.
• The Natural Forest Protection Project: Implemented in 1998, this project aims to protect natural forests and halt commercial logging to prevent deforestation and habitat loss.
• The Grain for Green Program: Introduced in the late 1990s, this program incentivizes farmers to convert marginal agricultural lands into forests, addressing soil erosion and land degradation.
• The South China Slopes Land Conversion Program: Started in the early 2000s, this program focuses on restoring vegetation cover on steep slopes in southern China to reduce landslides and improve water retention and ecosystem resilience.
• The Ant-Forest Program: Launched in 2011, this mobile app-based initiative encourages users to adopt eco-friendly habits and rewards them with virtual trees. Once a certain threshold is reached, real trees are planted in degraded areas.

Impact of Afforestation and Reforestation

China's afforestation and reforestation efforts have had a significant impact:

• From 1982 to 2021, Chinese citizens voluntarily planted approximately 78.1 billion trees across the country.
• China's forest coverage rate has more than doubled, increasing from 12% in the early 1980s to 24.02% in 2022.
• In 2022 alone, the Chinese people planted a total of 3.83 million hectares of new forests.
• China now has the world's largest planted forests, with a total area of 960 million mu (64 million hectares) over the past decade.
• A 2019 finding in Nature Sustainability showed that at least 25% of the global foliage expansion since the early 2000s came from China.
• China's forestry and grassland industry has become a significant source of revenue, with an output value of 8.37 trillion yuan (1.22 trillion USD) in 2022.
• China's efforts have contributed to addressing global climate change and promoting green and low-carbon development.
• China's initiatives have also positively impacted various industries, such as renewable energy, non-timber forest products, and green technology.

Future Plans

China has set ambitious goals for the future of its afforestation and reforestation efforts:

• China aims to increase its forest coverage rate to 26% by 2035, with a forest stock of 21 billion cubic meters and an area of natural forests kept at about 200 million hectares.
• Between 2021 and 2025, China plans to plant 36,000 square kilometers of new forest annually, an area exceeding the size of Belgium.
• China intends to continue its large-scale tree-planting efforts and improve its afforestation technologies to combat desertification.
