China's Pollution: Strategies For A Sustainable Future

China's pollution problem has been well-documented, with the country being home to many of the world's most polluted cities and the world's largest emitter of greenhouse gases. The Chinese government has declared a war on pollution, implementing various policies and measures to tackle this issue. This includes investing in renewable energy sources, reducing coal consumption, improving energy efficiency, and tightening air pollution controls. While China has made significant progress in reducing pollution levels and improving air quality, it still faces challenges such as increasing dependency on fossil fuels and the need to address multiple pollutants simultaneously.

Reforestation and afforestation programmes

China has implemented several reforestation and afforestation programmes as part of its efforts to reduce pollution and combat climate change. These initiatives aim to restore ecosystems, combat soil erosion, and improve air and water quality. Here are some key programmes:

The Three-North Shelterbelt Program (1978)

This large-scale programme covers 13 provinces, autonomous regions, or municipalities, totalling 4.069 million km2. It aims to increase tree coverage, stabilise soil, prevent sandstorms, and enhance ecological conditions in China's arid and semi-arid northern zones.

The Natural Forest Protection Project (1998)

Recognising the importance of natural forests in maintaining ecological balance and biodiversity, this project halted commercial logging in these ecosystems. It provided subsidies to farmers and allocated funds for conservation efforts, ensuring the long-term sustainability of natural forests.

The Grain for Green Program (1999)

Also known as the Grain-for-Green Program (GFGP), this is the world's largest reforestation programme. It provides economic incentives for farmers to convert marginal agricultural lands into forests, addressing soil erosion and land degradation. By 2013, the GFGP had reestablished 27.8 million hectares of forest in 26 of China's 31 mainland provinces, with a government commitment to continue until at least 2020.

The South China Slopes Land Conversion Program (2002)

Focusing on southern China, this programme encourages the conversion of steep slopes back into forests and grasslands to reduce landslides, improve water retention, and enhance ecosystem resilience. It also promotes sustainable land management practices to ensure the long-term conservation of natural resources.

The Ant-Forest Program (2011)

Developed by Ant Financial and the United Nations Environment Programme, this innovative programme integrates with the Alipay mobile app. Users earn "green energy points" for eco-friendly actions, and when a certain threshold is reached, real trees are planted in degraded areas.

China's reforestation efforts have led to significant forest expansion, with a 24% increase in forested areas between 2001 and 2021. The country plans to continue its large-scale tree-planting initiatives, aiming for carbon neutrality by 2060.

Reducing coal consumption

China is the world's largest producer and consumer of coal, with coal-fired power plants being the largest contributor to climate change and poor air quality in the country. In 2013, China experienced some of its highest pollution levels, and public criticism reached new heights. As a result, the Chinese government declared a war against pollution, implementing policies aimed at reducing coal consumption and controlling the number of energy-intensive projects in polluted regions.

One such policy was the China Coal Consumption Cap Project, launched in 2013, which aimed to implement a binding national cap on coal consumption. This initiative took into account local differences in air quality, clean energy availability, and economic status to help key provinces and cities develop their own action plans. The project set a goal to reduce the share of coal in the total energy mix from 64% in 2015 to 58% or less by 2020, a target that China is on track to achieve.

In addition to the national cap, China has also implemented policies at the local level to reduce coal consumption. For example, the government prohibited new coal-fired power plants and shut down old plants in the most polluted regions, including the city clusters of Beijing-Tianjin-Hebei and the Pearl and Yangtze Deltas. Large cities like Shanghai, Shenzhen, and Guangzhou have also played a role by restricting the number of cars on the road and introducing all-electric bus fleets.

China has also taken steps to boost renewable energy sources and reduce its dependence on coal. It aims to raise wind power capacity to 200 gigawatts and solar capacity to around 100 gigawatts by 2020. Additionally, China plans to increase natural gas output to more than 245 billion cubic meters per year by 2020 and move towards 50% renewable energy consumption by the middle of the century.

The efforts to reduce coal consumption in China have had positive results. From 2013 to 2020, particulate pollution in China declined by 39.6%, adding about two years to average life expectancy if these reductions are sustained. Beijing experienced the largest decline, with a 55% reduction in particulate pollution over seven years, adding 4.6 years to lives if sustained.

While China has made significant progress in reducing coal consumption and improving air quality, there is still more work to be done. Beijing, for example, is still three times more polluted than Los Angeles, the most polluted major city in the United States. Additionally, the progress has come with significant costs, such as leaving many households without heat during the winter after removing coal boilers. As China continues its "war against pollution", a focus on market-based approaches may help reduce pollution in a more sustainable and cost-effective manner.

Improving energy efficiency

The 13th Five-Year Plan (2016–2020) contained a mandatory national target to reduce energy intensity by 15% below 2015 levels by 2020. This target was missed when energy intensity improved by only 13.2%, due in part to the focus on energy-intensive industries in post-COVID economic recovery programs. The 14th Five-Year Plan (2021–2025) contains a mandatory national target to reduce energy intensity by 13.5% below 2020 levels by 2025.

China's progress in implementing mandatory energy efficiency policies over the past decade has made it the world's energy efficiency heavyweight. In 2018, more than 60% of China's energy use was covered by mandatory energy efficiency policies—more than any other nation in the world.

China has made huge strides in technical energy efficiency. Without the energy efficiency improvements made since 2010, China would have used 25% more energy in 2018. The evolution of China's economy, transitioning from energy-intensive sectors, mainly heavy industry, to the service sector, created structural changes that also helped reduce energy demand. The majority of efficiency gains were achieved in the industrial sector.

The International Energy Agency estimates that energy efficiency improvements since 2010 have cut energy consumption by 20%. They also estimate that energy efficiency improvements between 2000 and 2017 reduced China’s 2017 emissions by nearly 1.2 Gt CO2e (roughly equal to Japan’s 2017 emissions).

China has also invested in renewable energy sources. In 2019, renewables accounted for nearly 15% of China’s energy mix, compared to 7% a decade earlier. China has used hydropower for years and is installing more solar panels and wind power generators as the world’s leading manufacturer of those technologies.

The Chinese government has also introduced aggressive afforestation and reforestation programs like the Great Green Wall and planted more than 35 billion trees across 12 provinces. With investments of over $100 billion in such programs, China’s forestry expenditure per hectare exceeded that of the US and Europe and was three times higher than the global average.

Increasing use of clean and renewable energy

China is the world's top emitter of greenhouse gases, with coal making up nearly two-thirds of its energy consumption. However, the country has also been the biggest investor in renewable energy for seven years in a row, investing almost a third of the world's total investment in renewable energy in 2018.

China's renewable energy sources include solar energy, waste-to-energy technology, wind energy, and hydroelectric energy. The country has also been working to launch a national emissions trading scheme, which would incentivize polluters to reduce emissions by making them pay for environmental harm.

Solar Power

China is the world's leader in the production and sale of solar panels. In 2016, the Chinese government announced a five-year plan to decrease air pollution levels through investment in solar energy production technologies. This includes the installation of solar panels, with China aiming to have enough solar and wind power generators to reach a combined capacity of 1.2 billion kilowatts by 2030.

Wind Power

China is also the world's leader in the production and sale of wind turbines.

Electric Vehicles

China is the world's leader in the production and sale of electric vehicles. In 2020, 1.37 million so-called "new energy vehicles" were sold in China, an increase of nearly 11% from the previous year.

Nuclear Power

China is boosting its nuclear power capacity, with 17 reactors under construction as of mid-2021.

Geothermal Energy

Geothermal heating has zero carbon emissions and does not generate local air, water, or waste pollutants. The World Bank and Huaxia Bank have provided financing for geothermal energy projects, such as replacing coal-heating boilers with geothermal energy.

Green Financing

The World Bank-supported Innovative Financing for Air Pollution Control Program has financed investments in renewable energy and emissions control. The program has leveraged funding 5.4 times the original loan amount and supported China's efforts to reduce carbon dioxide emissions by 2.5 million tons per year.

Energy Efficiency

China is improving energy efficiency in the industrial and building sectors, reducing coal consumption and increasing the supply of renewable energy.

Clean Energy Vehicles

China is expanding its use of clean energy vehicles, such as electric buses in large cities like Shanghai, Shenzhen, and Guangzhou.

Afforestation and Reforestation

China has introduced aggressive afforestation and reforestation programs, such as the Great Green Wall, and has planted more than 35 billion trees across 12 provinces.

By increasing its use of clean and renewable energy, China is making significant strides in its war against pollution.

Reducing the number of cars on the road

China has been taking steps to reduce its air pollution, which has been linked to approximately 1.1 million premature deaths in the country each year. In 2013, China experienced some of its highest pollution levels, and public criticism reached new heights. The following year, Chinese Premier Li Keqiang declared a "war against pollution", and the country has since made significant progress in reducing pollution levels.

One of the key areas of focus for China in reducing pollution has been reducing the number of cars on the road. Large cities like Shanghai, Shenzhen, and Guangzhou have restricted the number of cars on the road and started introducing all-electric bus fleets.

• Promote Public Transportation: Encouraging the use of public transportation such as buses, metros, and trains is an effective way to reduce the number of private vehicles on the road. Improving the accessibility, affordability, and efficiency of public transportation systems can attract more riders and reduce car usage.
• Encourage Active Transportation: Promoting walking and cycling as alternative modes of transportation can significantly reduce the number of cars on the road. Developing infrastructure that supports these modes, such as dedicated bike lanes and pedestrian pathways, can make them more attractive and safer options.
• Implement Ride-Sharing Services: Encouraging the use of ride-sharing services, such as carpooling and ride-hailing apps, can help reduce the number of vehicles on the road. This approach maximizes the occupancy of each vehicle, minimizing the overall number of cars needed.
• Optimize Delivery and Shipping: Efficient delivery and shipping practices can reduce the number of vehicles on the road. This includes optimizing delivery routes, minimizing unnecessary trips, and consolidating packages to reduce the overall vehicle mileage.
• Remote Work and Flexible Schedules: Encouraging remote work and flexible schedules for employees can help reduce commuting trips. Allowing employees to work from home, even on a hybrid schedule, can significantly decrease the number of vehicles on the road during peak hours.
• Vehicle Efficiency and Maintenance: Promoting the use of fuel-efficient vehicles and ensuring proper vehicle maintenance can also reduce emissions. Encouraging the adoption of electric, hybrid, and fuel-efficient vehicles, as well as regular tune-ups and proper tire inflation, can lower emissions from vehicles that remain on the road.
