China's War On Pollution: Strategies And Successes

China has made significant progress in tackling pollution, particularly air pollution, which has caused a public health crisis in the country, killing more than 1.1 million people annually. The government has implemented various initiatives, such as the Air Pollution Action Plan, which has helped improve air quality in major cities. Beijing, once shrouded in smog, has made remarkable strides, setting an example for other cities. China has also invested in afforestation and reforestation programs, planted billions of trees, and promoted renewable energy development. Despite these efforts, challenges remain, including China's increased dependence on fossil fuels, and the need to address other pollutants like ozone, which contribute to respiratory and cardiovascular health risks.

Reducing PM2.5 levels

China has implemented a series of comprehensive strategic plans and programs to reduce PM2.5 levels and combat the air pollution crisis.

The Chinese government's Air Pollution Action Plan, released in September 2013, became the country's most influential environmental policy, helping to significantly improve air quality between 2013 and 2017. The plan focused on reducing PM2.5 levels, with a target of a 25% reduction from 2012 to 2017. This resulted in a 33% reduction in Beijing and a 15% reduction in the Pearl River Delta. Beijing achieved an annual average PM2.5 level of 58µg/m³, a drop of 35%. However, it should be noted that even with these improvements, no Chinese city has reached the World Health Organization's recommended annual average PM2.5 level of 5-10µg/m³.

To achieve these reductions in PM2.5 levels, China implemented various initiatives and policies. One key factor was the expansion of urban rail, transforming the country's car-centric transportation system into a more sustainable mobility model. The establishment of a state-of-the-art integrated air quality monitoring network, utilising technologies such as HD satellite, remote sensing, and laser radar, helped China better monitor pollution levels and identify areas emitting high levels of pollutants.

China also introduced Low Emission Zones (LEZs), which restrict access for polluting vehicles and encourage the adoption of cleaner, emission-compliant modes of transportation. Additionally, initiatives like license plate lotteries, driving bans, and incentives for scrapping older vehicles further demonstrated Beijing's commitment to phasing out polluting vehicles. The city also incentivized the use of new energy vehicles (NEVs) and modernized its bus fleet.

Another important aspect of China's strategy to reduce PM2.5 levels was its focus on reducing coal consumption. The government prohibited new coal-fired power plants and shut down older plants in highly polluted regions, including Beijing, Tianjin, Hebei, and the Pearl and Yangtze Deltas. China also implemented policies to improve heating systems and shut down industrial sites to decrease coal usage.

China's efforts to tackle air pollution and reduce PM2.5 levels have had positive impacts on both the environment and public health. The country has seen significant reductions in pollution levels and associated health risks, with research suggesting that the decline in air pollution could lead to an increase in life expectancy of 2.4 years on average.

Improving air quality

China's air pollution levels at the turn of the century were comparable to London's during the Industrial Revolution. However, China has since made significant progress in improving its air quality, with recent research suggesting that these improvements could lead to gains in life expectancy for the average citizen of 2.4 years.

China's air quality improvements are the result of a series of comprehensive strategic plans and programs. The Chinese government's Air Pollution Action Plan, released in September 2013, is considered the country's most influential environmental policy. The plan targeted a reduction in PM2.5 levels (atmospheric particulate matter) and led to significant improvements in air quality between 2013 and 2017. The PM2.5 level in Beijing, for example, decreased by 33%.

To achieve these improvements, China implemented various initiatives. One key factor was the expansion of urban rail, transforming the country's car-centric transportation system into a more sustainable mobility model. China also established a state-of-the-art integrated air quality monitoring network that utilized advanced technologies such as HD satellite, remote sensing, and laser radar. This network, with over 1000 sensors across cities, helped identify the areas emitting the highest levels of pollution.

China also introduced Low Emission Zones (LEZs), which restricted access for polluting vehicles and incentivized the adoption of cleaner, emission-compliant modes of transportation. Beijing, for instance, implemented driving bans and provided incentives for scrapping older vehicles. The city also focused on reducing coal consumption by shutting down industrial sites and improving heating systems.

In addition to these measures, China invested heavily in afforestation and reforestation programs, such as the Great Green Wall, planting more than 35 billion trees across 12 provinces. These programs, with investments exceeding $100 billion, contributed to a significant reduction in pollution and the near-elimination of sandstorms in Beijing during spring.

While China has made remarkable progress, it is important to recognize that challenges remain. China's PM2.5 levels still fall short of the World Health Organization's recommended annual average of 10µg/m³, and the country continues to struggle with its dependence on fossil fuels. Nevertheless, China's efforts provide a model for other cities and countries grappling with similar issues, demonstrating that comprehensive policy action and strategic planning can lead to significant improvements in air quality.

Investing in renewable energy

China's investment in renewable energy has been a long time coming, with the country aiming to position itself as a global leader in the sector. In 2015, China became the world's largest producer of photovoltaic power, with 43 GW of total installed capacity. From 2005 to 2014, its production of solar cells expanded 100-fold.

China has made strategic investments in all aspects of renewable technologies, including solar and wind capacity, green hydrogen, and geothermal projects. In 2020, China pledged to double its renewable energy capacity by 2030, a goal it achieved six years ahead of schedule. In 2024, China led the world in energy transition investment, accounting for two-thirds of the $2.1 trillion spent globally.

China's renewable energy dominance is driven by its state-owned enterprises and traditional energy companies, which have been compelled to shift towards renewable investments. The country's massive wind farms in the north and utility-scale clean energy bases in the western desert regions are notable examples of this shift.

China's Belt and Road Initiative further showcases its commitment to renewable energy. While the country has historically invested in coal power projects overseas, it has recently shifted towards financing renewable power. In 2024, China committed $51 billion to support African development and build 30 low-carbon energy projects over three years.

Despite these efforts, China's economy remains heavily reliant on traditional energy sources, particularly coal. In 2024, China's coal power construction hit a 10-year high, and the country is still the world's biggest emitter of greenhouse gases. However, estimates predict that by 2026, solar energy will overtake coal as China's leading energy source.

Reducing coal consumption

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 emitter of greenhouse gases, China has implemented a series of comprehensive strategic plans and programs to combat the pollution crisis.

One key initiative has been to reduce coal consumption. The Chinese government published a plan in September 2013 to tackle air pollution by reducing coal consumption and closing polluting mills, factories, and smelters. The government also prohibited new coal-fired power plants and shut down old plants in highly polluted regions, including Beijing-Tianjin-Hebei and the Pearl and Yangtze Deltas.

Beijing, in particular, has made remarkable strides in improving its air quality. The city has focused on reducing coal consumption by shutting down industrial sites and improving heating systems. Additionally, initiatives like Low Emission Zones (LEZs) and incentivizing new energy vehicles (NEVs) have contributed to reduced pollution levels.

While China has made significant progress in reducing coal consumption, it still faces challenges. Due to electricity shortages, China authorized a significant increase in coal power in 2021, and coal production reached a record high in 2023. China's increased dependence on fossil fuels and the rising trend of pollutants like ozone are also concerns that need to be addressed.

Improving soil pollution

China's environmental crisis, caused by decades of rapid industrialization, has resulted in soil contamination, threatening the health and livelihoods of its people. Soil pollution, a sensitive topic in China, has contaminated food crops and jeopardized public health. Heavy metal contamination, such as cadmium, lead, and mercury, has rendered farmland unsuitable for growing crops.

To tackle soil pollution, China has implemented various measures:

• National Soil Census: China launched a national soil census to update data on soil conditions, recognizing the heavy price soil has paid during rapid economic growth.
• Action Plans: The government drafted action plans to address land pollution in 2016, but struggled with financing clean-up initiatives, especially in old industrial and rural areas.
• Reducing Fertilizer Use: China's excessive fertilizer use, contributing to soil acidification and hardpan soil, poses challenges to food security.
• Rehabilitating Contaminated Land: By 2020, China aimed to rehabilitate approximately 667,000 hectares of contaminated farmland and reuse industrial sites, requiring significant capital investment.
• Legal Measures and Environmental Reforms: Implementing legal measures and reforming the environmental protection system is crucial for tackling soil pollution during land redevelopment.
• Diversifying Financing: China is exploring public-private partnerships and pollution insurance to secure funding for soil pollution control initiatives.

While China has made efforts to address soil pollution, the implementation and coordination of these initiatives remain challenging. The success of the national action plan relies on stable and sustainable financial resources.
