Beijing has a four-tier system for alerting residents about air pollution levels. The highest level is a red alert, which is issued when the air quality deteriorates to a level where people should stay indoors. The second-highest level is an orange alert, which is issued when the Air Quality Index (AQI) is expected to exceed 200 for two consecutive days or 150 for three consecutive days. During a red alert, driving is restricted, schools are closed, and some factories are shut down. During an orange alert, some businesses may reduce operations, and the U.S. EPA recommends that certain groups limit or avoid outdoor physical activity.

Beijing's red alert is the highest level of air quality warning
Beijing's red alert is the highest possible warning level in the city's four-tier system for air quality. The red alert is issued when the Air Quality Index (AQI) is expected to surpass 200 for three consecutive days or exceed 300 for two consecutive days. When a red alert is issued, driving restrictions are imposed, schools are closed, and some factories are shut down.
On November 30, 2015, Beijing issued its first-ever red alert for air pollution. The alert lasted from 7 a.m. on Tuesday to midday on Thursday. During this period, car use was limited, with only cars with odd-numbered license plates allowed on the roads on the first day, followed by those with even-numbered plates on the next day. Schools were closed, and some factories were ordered to stop operations. The air pollution at the time was mainly caused by a cloud of pollution that settled over Northern China, including Beijing, and was worsened by weather conditions and the city's geography.
Beijing has experienced subsequent red alerts for air pollution, indicating that the issue is ongoing. In December 2016, the city issued its third red alert, which lasted for five days. During this period, kindergartens, primary schools, and high schools were advised to suspend classes, outdoor operations on construction sites were banned, and some industrial plants were required to limit or stop production.
The severe air pollution in Beijing has been attributed to various factors, including coal-burning heavy industries and steel production in the surrounding provinces. While Beijing has implemented measures such as investing in improving air quality and replacing coal-fired heating systems with natural gas heating systems, the complexity of the issue remains a challenge. The political stakes in handling environmental problems in China are high, and the country's participation in global discussions on climate change and carbon emissions reduction demonstrates its recognition of the urgency of the situation.

The orange alert is the second-highest level
Beijing's air pollution is a painful reminder of the price the country has paid for its rapid economic development over the preceding decades. The Chinese government has demonstrated an unprecedented level of openness to discussing the global challenge of climate change and has declared a "war on pollution" to show its resolve in addressing the issue.
Beijing's air pollution alert system consists of four tiers, with the red alert being the highest and most serious level. The orange alert is the second-highest level of this four-tier system. An orange alert indicates that the Air Quality Index (AQI) will exceed 200 for two consecutive days or 150 for three consecutive days. During an orange alert, some businesses may reduce operations, and people with heart or lung disease, older adults, children, and teenagers are advised to limit or avoid outdoor physical activity.
The orange alert is a crucial step before the issuance of a red alert. A red alert is declared when the AQI is expected to surpass 200 for three consecutive days. When a red alert is issued, driving restrictions are put in place, schools are closed, and some factories are shut down. It is a warning to the public to take extra precautions and prepare for the possibility of further deterioration in air quality.
The orange alert serves as a critical warning to the public and authorities alike. It indicates that air pollution levels are reaching concerning levels and that immediate action is required to mitigate the situation. It is a balance between ensuring the public's safety and maintaining essential economic activities. The orange alert allows businesses and individuals to prepare for the potential impact of further deterioration, highlighting the delicate interplay between public health, environmental concerns, and economic stability.

Driving restrictions, school closures, and factory shutdowns are implemented
Beijing has long been one of the largest metropolitan areas that struggle with poor air quality. The economic boom of Beijing has been accompanied by mounting environmental pollution, making development "costly and fragile". The air quality monitoring data for 2014–2018 recorded PM2.5 concentrations over seven times higher than the maximum exposure limit established by the World Health Organization. As air pollution became an increasing concern for residents, the Beijing government has adopted various transportation policies to alleviate both traffic congestion and air pollution.
Driving restriction policies have become a politically acceptable measure worldwide to deal with congestion and air pollution. Beijing was the first Chinese city to adopt such policies. However, studies suggest that in the short run, driving restrictions do not affect the total concentrations of PM2.5 pollutants.
In light of this, it is understandable that Beijing issued a "red alert", the highest in its four-tier system, in response to dangerous levels of air pollution. As a result, driving restrictions, school closures, and factory shutdowns were implemented.
The air quality index of 308, recorded on a Tuesday afternoon, is over ten times higher than the levels recommended by the World Health Organization. By US standards, anything above 300 is "hazardous", meaning people should stay indoors. The issuance of the "red alert" was the first time since the government introduced a colour-coded emergency response plan to air pollution in 2013.
Despite the efforts of municipal officials, Beijing's air pollution is not solely due to a lack of political will. Pollution often originates in surrounding areas with coal-burning factories where environmental regulations and enforcement are more lenient. Nonetheless, the Chinese government has demonstrated a commitment to addressing environmental issues, declaring a "war on pollution" in 2014.

Beijing's air pollution is a result of coal-burning heavy industries in surrounding provinces
Beijing's air pollution is a complex issue resulting from various factors, including coal-burning heavy industries in surrounding provinces. As China's capital and one of the world's most populous cities, Beijing faces significant challenges in maintaining air quality.
The city's topography, surrounded by mountains, traps pollution, and its proximity to industrial areas exacerbates the problem. Beijing's rapid economic growth, population increase, and surge in motor vehicles have also contributed to the poor air quality.
Coal-burning industries, particularly in the surrounding regions, play a significant role in Beijing's air pollution. These industries rely on outdated and inefficient technologies, emitting high concentrations of sulfur dioxide and particulate matter, leading to the formation of acid rain and smog. The nearby cities of Harbin, Hebei, and Tianjin are known for their heavy industries, and their emissions directly impact Beijing's air quality.
To address this issue, there have been efforts to transition from coal to natural gas and cleaner fuels in these surrounding provinces. However, the enforcement of environmental regulations and the implementation of new energy sources vary, with some areas having more lenient standards, hindering the overall effectiveness of these measures.
The Chinese government has recognized air pollution as a significant social and political challenge. In 2013, Beijing Mayor Wang Anshun prioritized air quality improvement, allocating significant funds to replace coal-fired heating systems with natural gas alternatives. Additionally, in 2018, the government announced a plan to replace coal-burning heaters in millions of homes across several cities.
The alert system for air pollution, with colors like orange and red, serves as a reminder of the urgency of the situation. During an orange alert, some businesses may reduce operations, and people are advised to limit outdoor physical activity, especially those with health conditions. A red alert, the highest warning level, leads to school closures, driving restrictions, and the shutdown of some factories.

The Chinese government has demonstrated a commitment to addressing environmental issues
In Beijing, the capital of China, the air quality index of 308 is over ten times higher than the levels recommended by the World Health Organization. The Beijing City Government has issued a “red alert” for air pollution, the highest of the four-tier alert system, and an “orange alert”, the second-highest alert. During such alerts, driving is restricted, schools are closed, and some factories are shut down.
Furthermore, China has made several pledges and commitments to address climate change and environmental issues. In 2020, President Xi Jinping pledged that China would peak carbon emissions before 2030 and achieve carbon neutrality before 2060. China's central government has issued "working guidance" on the country's efforts to peak carbon emissions and achieve carbon neutrality, which lays the foundation for China's "1+N" climate policy system. China has also made commitments at the Our Ocean Conferences from 2014 to 2019, valued at over $4.3 billion, to promote sustainable fisheries, combat marine debris, and support marine science, observation, and exploration.
In addition to international cooperation, China has taken domestic actions to address environmental issues. In 2008, the National Development and Reform Commission (NDRC) released its first white paper on climate change, titled "China's Policies and Actions for Addressing Climate Change". The NDRC has been delegated the policy-making power to decide what policies should be included in the 1+N design and will work with local authorities to coordinate the implementation of action plans. The Chinese government has also introduced laws and regulations concerning environmental protection, air pollution, renewable energy, and energy efficiency, which have elements that address climate change.
However, it is important to acknowledge that China faces significant environmental challenges, and there have been criticisms of its environmental record. China is currently the world's largest emitter of greenhouse gases and has been since 2006. China's energy-related carbon dioxide emissions are rising, and it is the world's greatest emitter of mercury, a major public health threat. China's rapid economic development has come at an environmental cost, and there is criticism that the country has prioritized economic growth over environmental protection. Nonetheless, the Chinese government continues to demonstrate a commitment to addressing environmental issues, and its efforts are ongoing.
