Reduce air pollution by cutting coal consumption
China's environmental crisis is a result of decades of rapid industrialization, threatening the health and livelihoods of its 1.4 billion citizens. The country's poor air quality is a well-known issue, with the rapid economic expansion since 1979 leading to a drastic increase in coal-powered industrial production and electricity demand. China's carbon emissions, with the country being the world's top emitter, producing over a quarter of the world's annual greenhouse gas emissions, pose a significant threat to global efforts to combat climate change.
To reduce air pollution by cutting coal consumption, China has implemented several measures. Beijing, the capital, has been at the forefront of these efforts, aiming to reduce PM2.5 by 25% from 2012 to 2017. The Chinese government published a plan in 2013 to tackle air pollution, with a key goal of reducing coal consumption. This involved closing polluting mills, factories, and smelters, and transitioning to eco-friendly energy sources. As a result, between 2013 and 2015, the average PM2.5 in 74 key cities decreased by 23.6%.
To further reduce coal consumption and mitigate air pollution, China can focus on improving the efficiency of burning coal to generate more power with less coal. This approach is already being implemented in new high-efficiency power plants, which are expected to reduce CO2 emissions by 7%. Additionally, China can explore the utilization of Integrated Gasification Combined Cycle (IGCC) coal-fired power plants, which burn coal more efficiently and emit less pollution. While the technology may not be economically viable, it could be a temporary solution while more desirable alternative power generation methods become practical.
Another strategy to reduce coal consumption and air pollution is to implement carbon capture and storage technologies (CCS). These emerging technologies enable coal plants to capture CO2 emissions, which can then be transported and stored safely. While the technology is expensive and unproven at the required scale, it has been adopted in a few projects worldwide, and the federal government has invested billions of dollars in CCS research.
By focusing on increasing burning efficiency, transitioning to eco-friendly energy sources, and exploring carbon capture solutions, China can effectively reduce air pollution by cutting coal consumption. These measures will not only improve the health and well-being of its citizens but also contribute positively to global efforts to address climate change.

Improve water quality and address scarcity
China's water quality and scarcity issues are largely the result of industrial pollution, rapid urbanization, and climate change. With only about 6% of global renewable freshwater resources, China's water resources are under immense strain. Here are some measures that can be taken to improve water quality and address scarcity:
Firstly, the Chinese government should prioritize reducing industrial pollution, which has contaminated waterways and made them unfit for human use. This includes enforcing stricter environmental regulations and promoting sustainable practices in industries such as metal smelting and battery manufacturing, which have been major contributors to water pollution.
Secondly, China should invest in wastewater treatment infrastructure and technology. Despite economic growth, many residents in developed cities still need to boil and filter tap water due to inadequate water treatment facilities and aging underground pipes. Upgrading these systems can improve water quality and reduce the risk of waterborne diseases.
Thirdly, addressing water scarcity requires a comprehensive approach. The government should continue its efforts to improve access to water, especially in urban areas. This can include investing in water conservation initiatives, such as The Nature Conservancy's (TNC) water funds, which support upstream land conservation and restoration. Additionally, implementing water-saving measures, such as restricting farming near major rivers to limit agricultural runoff, can help reduce water pollution and preserve water resources.
Furthermore, China should focus on improving land management practices, particularly in agricultural areas. Fertilizers, pesticides, and livestock waste are significant contributors to water pollution, and implementing measures to reduce runoff from these sources can improve water quality. Reforestation projects, such as the Great Green Wall of China, can also help stabilize ecosystems and improve water flows while providing additional benefits like improved agricultural productivity.
Finally, China should continue to prioritize health risk assessments and emergency response plans related to drinking water safety. This includes strengthening the infrastructure for centralized water supplies and improving the monitoring and treatment of drinking water to ensure its safety.

Reduce lead poisoning and other health impacts
China's environmental crisis, caused by rapid industrialization, poses a threat to the health and livelihoods of its 1.4 billion people. Lead poisoning, in particular, has emerged as a pressing issue, with a 2001 paper describing it as one of the most common paediatric health problems in the country. A 2006 review of existing data further suggested that a third of Chinese children suffer from elevated serum lead levels. This has had detrimental long-term impacts on their health, affecting their mental and physical development.
Sources of lead exposure in China vary from region to region and are influenced by cultural practices and industrial activities. Lead-contaminated folk medicine, tin pots, and tinfoil have been identified as common sources of non-industrial lead exposure. In industrial settings, pollution from metal smelters and battery factories has been responsible for high lead levels, with workers and nearby residents, including children, suffering from toxic lead exposure.
To reduce lead poisoning and its health impacts, China has implemented measures such as suspending battery factory production. However, these efforts have been criticized as inadequate. To effectively address lead poisoning, a combination of government policies, public education, and individual precautions is necessary.
The government should prioritize setting and enforcing strict regulations on lead pollution, including limiting lead emissions from industrial sources and ensuring lead-safe practices in manufacturing. Additionally, investing in research and monitoring systems to identify lead hotspots and track lead levels in at-risk populations can help guide targeted interventions.
Public education plays a crucial role in empowering individuals and communities to protect themselves from lead exposure. Healthcare professionals can utilize social media platforms, such as WeChat, to disseminate accurate information about lead poisoning, including its sources, health effects, and prevention strategies. Educating parents and caregivers about the risks of lead exposure and simple precautions, such as handwashing and regular toy cleaning, can significantly reduce lead exposure in children.
On an individual level, people can take precautions to minimize lead exposure. This includes measures such as removing shoes before entering the house, running cold water before using it for drinking or cooking (especially if there are older pipes), and avoiding the use of lead-based products like certain types of paint and pottery. Eating a healthy diet and maintaining proper nutrition can also help lower lead absorption in the body.

Stop illegal fishing and overfishing
China's environmental crisis, the result of decades of rapid industrialization, threatens the health and livelihoods of its 1.4 billion people and the global fight against climate change. The country's poor air quality, water scarcity, and soil contamination are among the most pressing issues. In addition, China's expanding fishing fleet has been linked to illegal, unreported, and unregulated fishing practices, contributing to overfishing and depleting the world's oceans. Here are some measures that can be taken to address this issue:
Firstly, the Chinese government should cease subsidizing the fishing industry and coercing foreign governments to minimize enforcement against Chinese fishing vessels. The government has been criticized for robustly supporting the industry with billions of yuan in subsidies annually, including diesel fuel subsidies and the construction of advanced steel-hulled trawlers. This has enabled Chinese vessels to travel far and wide, even venturing into protected waters and infringing upon the sovereignty of other nations. The government should also refrain from using fishing vessels as part of its maritime militia, operating in waters closer to home.
Secondly, there should be increased transparency and accountability in the fishing industry. China's global fishing fleet consists of over 57,000 industrial fishing vessels, dominating 44% of the world's visible fishing activity. However, this massive presence has been linked to illegal, unreported, and unregulated fishing, as well as human rights abuses at sea. To address this, China should ensure that its vessels transmit automatic identification system (AIS) data, making them "visible" to public tracking systems. This transparency is crucial for effective monitoring and enforcement of fishing regulations.
Thirdly, China should collaborate with the international community to combat illegal fishing and overfishing. As illegal fishing activities occur across multiple countries, joint efforts are necessary to address this global issue. The 2022 U.S. National Security Strategy, for instance, emphasizes the need for U.S. support to allies and partners affected by Chinese coercion in the fishing industry. By working together and sharing information, countries can better enforce regulations, deter illegal activities, and hold offenders accountable.
Lastly, China should continue its efforts to restrict its distant-water fishing fleet. In 2017, the Chinese government released a five-year plan to limit the total number of offshore fishing vessels to under 3,000 by 2021. This was a positive step, and further measures in this direction should be encouraged. Reducing the number of vessels can help decrease China's fishing footprint and alleviate pressure on the world's oceans.
By implementing these measures, China can play a more responsible and sustainable role in the global fishing industry, contributing to the protection of marine ecosystems and the livelihoods of people dependent on fisheries worldwide.
