# Environment of China

The environment of China (Chinese: 中国的环境) comprises diverse geology, rich biota, and varied climates, ranging from arid deserts to subtropical forests. However, Rapid industrialization, population growth, and lax environmental oversight have caused many environmental issues and large-scale pollution, including severe air pollution. China faces critical issues such as some of the highest levels of air pollution globally, with fine particulate matter (PM2.5 and PM10) linked to adverse health effects and increased mortality. Additionally, climate change has intensified extreme weather events, rising temperatures, further impacting ecosystems and human populations. In response, the Chinese government has implemented extensive environmental policies, such as the Air Pollution Prevention and Control Action Plan and the Ecological Civilization Initiative, along with carbon neutrality goal to combat climate change.

## Geology

The geology of China (or the geological structure of the People's Republic of China) consists of three Precambrian cratons surrounded by a number of orogenic belts. The modern tectonic environment is dominated by the continued collision of India with the rest of Asia starting 40–50 million years ago. This has formed the Himalayas and continues to deform most of China. China has vast mineral reserves, a significant earthquake risk in its western regions and rare isolated active volcanoes throughout the country.

## Biota
### Wildlife

China's vast and diverse landscape is home to a profound variety and abundance of wildlife. As of one of 17 megadiverse countries in the world, China has, according to one measure, 7,516 species of vertebrates including 4,936 fish, 1,269 bird, 562 mammal, 403 reptile and 346 amphibian species. In terms of the number of species, China ranks third in the world in mammals, eighth in birds, seventh in reptiles and seventh in amphibians.
Many species of animals are endemic to China, including the country's most famous wildlife species, the giant panda. In all, about one-sixth of mammal species and two-thirds of amphibian species in China are endemic to the country.

## Climate

Owing to tremendous differences in latitude, longitude, and altitude, the climate of China is extremely diverse, ranging from tropical in the far south to subarctic in the far north and alpine in the higher elevations of the Tibetan Plateau. Monsoon winds, caused by differences in the heat-absorbing capacity of the continent and the ocean, dominate the climate. During the summer, the East Asian Monsoon carries warm and moist air from the south and delivers the vast majority of the annual precipitation in much of the country. Conversely, the Siberian anticyclone dominates during winter, bringing cold and comparatively dry conditions. The advance and retreat of the monsoons account in large degree for the timing of the rainy season throughout the country. Although most of the country lies in the temperate belt, its climatic patterns are complex.
The northern extremities of both Heilongjiang and Inner Mongolia have a subarctic climate; in contrast, most of Hainan Island and parts of the extreme southern fringes of Yunnan have a tropical climate. Temperature differences in winter are considerable, but in summer the variance is considerably less. For example, Mohe County, Heilongjiang has a 24-hour average temperature in January approaching −30 °C (−22 °F), while the corresponding figure in July exceeds 18 °C (64 °F). By contrast, most of Hainan has a January mean in excess of 17 °C (63 °F), while the July mean there is generally above 28 °C (82 °F).
Precipitation is almost invariably concentrated in the warmer months, though annual totals range from less than 20 millimetres (0.8 in) in northwestern Qinghai and the Turpan Depression of Xinjiang to easily exceeding 2,000 millimetres (79 in) in Guangdong, Guangxi, and Hainan. Only in some pockets of the Dzungaria region of Xinjiang is the conspicuous seasonal variation in precipitation that defines Chinese (and, to a large extent, East Asian) climate absent.
Annual sunshine duration ranges from less than 1,100 hours in parts of Sichuan and Chongqing to over 3,400 hours in northwestern Qinghai. Seasonal patterns in sunshine vary considerably by region, but overall, the north and the Tibetan Plateau are sunnier than the south of the country.

### Climate change

Climate change is having major effects on the Chinese economy, society and the environment. China is the world's largest emitter of carbon dioxide, through an energy infrastructure heavily focused on coal. China's per capita emissions are greater than the world and European Union averages but less than Australia, Canada, and the U.S. China recorded its hottest year on record in 2023, with an average temperature of 10.7 °C. On the basis of cumulative CO$_2$ emissions measured from 1751 through to 2017, China is responsible for 13% of global and about half of the United States' cumulative emissions.
A burgeoning construction industry and industrial manufacturing contribute heavily to carbon emissions. It has also been noted that higher-income countries have outsourced emissions-intensive industries to China.
In 2024, China yet again recorded its hottest year on record, with an average temperature of 10.92 °C, or 51.66 degrees Fahrenheit.

## Protected areas of China

This is a list of the nationally designated protected areas of China. There are many forms of protected areas in China. Based on their relative importance, each type of protected area can be further graded into two to three levels (national, provincial and prefectural/county level). Nevertheless, the highest rank for "pocket nature preserve" (social and mass-based), "no-hunting area", "no-fishing area", "no-logging area", "wild medicinal material resources conservation area", "crop germplasm resources conservation area", "forest tree germplasm resources conservation area" or "source water protection area" is practically restricted to provincial level. The local government at county level is also responsible for the delimitation and declaration of "basic farmland protection area" and "basic grassland".

### UNESCO World Heritage Sites

Within China’s protected areas are some United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage sites. According to the UNESCO World Heritage website, these sites are “designation for places on Earth that are of outstanding universal value to humanity and as such, have been inscribed on the World Heritage List to be protected for future generations to appreciate and enjoy.”
China alone has 59 sites, including, but not limited to: The Great Wall of China, The Imperial Palace, and The Temple of Heaven. These are cultural sites, and are protected because of their significant contributions to China’s culture. Fifteen of these fifty nine sites, or 23.7% of these sites are categorized as “natural” sites, as opposed to “cultural” or “mixed” sites.These natural sites include famous rivers (Three Parallel Rivers of Yunnan), animal sanctuaries (Sichuan Giant Panda Sanctuary), and “historic and interest areas” (Jiuzhaigou Valley Scenic and Historic Interest Area). Fujian’s Wuyi Mountains, as listed above, are categorized as “mixed.”
The UNESCO World Heritage Site list is always being updated, as countries can nominate additional sites to be included as a UNESCO World Heritage Site. As per the UNESCO page dedicated to the nominations process, the process requires countries to be signatories on the “World Heritage Convention, pledging to protect their natural and cultural heritage.” China has 59 additional sites that are on the “tentative list” as of March 2025. These sites include the natural reserves like the Dongzhai Port National Reserve and the Alligator Sinensis Nature Reserve, scenic zones like the Lijiang River Scenic Zone at Guilin, and historically relevant cultural relics like the City Walls of the Ming and Qing Dynasties.
UNESCO World Heritage also offers a “State of Conservation” section, in which any threats to these environments can be reported and monitored. More specifically: “The Information System offers you a trove of reliable data on the state of conservation of World Heritage properties since 1979 and the threats they have faced in the past, or are currently facing.” China has 28 properties that are listed under “concerned.” Many of the sites China has listed under “concerned” include threats of tourist impact, management systems, housing, and legal frameworks.

## Environmental issues

Rapid industrialization, population growth, and lax environmental oversight have caused many environmental issues, such as large-scale pollution in China.
According to Jared Diamond, the six main categories of environmental problems of China are: air pollution, water problems, soil problems, habitat destruction, biodiversity loss and mega projects. Diamond also states that, "China is noted for the frequency, number, extent, and damage of its natural disasters".
Studies show that particulate like PM10 and PM2.5 levels in China are among the highest in the world, which post significant public health risks. By analyzing 16 cities, Research found that a 10 g/m³ increase in PM10 was associated with a 0.35% rise in total mortality, a 0.44% increase in cardiovascular mortality, and a 0.56% increase in respiratory mortality. In January 2013, fine airborne particulates that pose the largest health risks, rose as high as 993 micrograms per cubic meter in Beijing, compared with World Health Organization guidelines of no more than 25. The World Bank estimates that 16 of the world's most-polluted cities are located in China. As of 2013, Beijing, which lies in a topographic bowl, has significant industry, and heats with coal, is subject to air inversions resulting in extremely high levels of pollution in winter months.
A study by Wenqi Wu use a difference-in-difference-in-difference model to analyze air pollution across 290 Chinese cities from 2007 to 2021. They found that joint regional pollution control measures significantly reduced PM2.5 and industrial sulfur dioxide emissions, particularly in the Yangtze River Delta and the Pearl River Delta. However, the Beijing-Tianjin-Hebei region showed less improvement, possibly due to economic disparities and governance challenges.
An effort made by the government aim to address this problem was the implementation of the Air Pollution Prevention and Control Action Plan (APPCAP), which was implement between 2014 and 2018. This policy led to significant improvements in Beijing’s air quality, reducing key pollutants such as PM2.5, PM10, NO2, SO2, and CO. A study of 35 monitoring sites in Beijing found that PM2.5 levels declined significantly. It contribute to a 5.6% decrease in pollution-related mortality. However, during the same period ozone (O3) levels increased. Additional policy such as the Best Available Control Technologies (BACT) and Advanced Coal Gasification Technologies (ACGT) have been proposed. Research suggest that implementing these policy could reduce pollution related health damages by 20–50%.
Public perception of air pollution in China remains a critical force in china Environmental policy. Many Chinese citizens have expressed concerns over whether air pollution is responsible for increasing lung cancer. This question began to rise because the citizens in China must constantly wear face masks to avoid breathing in the hazardous particles from their polluted skies. Some experts agree that it is the reason, but others say there isn't enough evidence. Wang Ning, deputy director of the Beijing Office for Prevention and Control, says he has seen a rise in a certain cancer called adenicarcinoma, which is a mucus that is seen as a side effect from pollution. China's lung cancer rate is 32% of the entire world's lung cancer patients. Meanwhile, as lung cancer increases, gastric, esophageal, and cervical cancer have all decreased in China. In particular, elderly, women, and individuals with lower education levels, are disproportionately affected. Regional disparities also highlight inequalities in environmental health as cities with higher baseline pollution levels tend to exhibit lower per-unit health impacts, possibly due to physiological adaptation, while cities with lower pollution levels with greater health effects per unit increase in pollution. A survey of Nanchang residents found that 69% believed air quality had deteriorated. They identify that motor vehicles, waste burning, and industrial facilities are the main contributors. The survey also suggested strong public demand for stricter regulations, with 96.8% of respondents supporting increased government investment in air pollution control.
