Site Map

Welcome to the China Air Pollution Map Database. By simply clicking on different map regions, website users will be able to investigate information on a given region's air quality, amount and sources of air emission, including information on enterprises and power plants that exceed emission standards.

ATTENTION: On Air Quality and Amount of Emission, the Phase I of the Map provides data of 15 southern provinces and 150 municipalities of these provinces.

Website users will be able to view rankings of the levels of various air pollutants and gain a better understanding of the air quality in their own region.

ATTENTION: Phase I of the Map provides ranking of data of 15 southern provinces and 150 municipalities of these provinces.

Administrative Map

Administrative Map

On the front page there is a map of China. By clicking on the name of the provinces on that map, the provincial map will be opened. By clicking on the name of cities on a provincial map, the municipal maps could be opened. The provincial and municipal maps can also be opened by clicking on the names at the right hand side bar.

Under each map the viewers will access that region’s air quality, amount and sources of air emission.

1. Air Quality Information

Air quality information includes summary of urban air quality、acid rain description、major pollution factors description, contamination events, annual average daily sulfur dioxide (SO2) concentration, annual average daily nitrogen oxides (NO2) concentration, annual average daily carbon monoxide (CO) concentration, annual average daily inhalable particulate matter (PM10) concentration, average dustfall, annual average daily total suspended particulate (TSP), rain pH, frequency of acid rain , etc.

The definition of the terms can be viewed at Word Explanation. (In Chinese only at the moment.)

NOTE: As the government environmental reports give sporadic disclosure of carbon monoxide, TSP and API, the Air Pollution Map has gaps on these three indicators.

NOTE: The air quality data is more complete and more consistent for the year 2004 and 2005 because SEPA compiled such data of several dozen cities in its annual report on national urban environment management and comprehensive rectification. In 2006 SEPA substituted specific emission data on sulfur dioxide, nitrogen dioxide and inhalable particulates with a vague proportion figure that shows the number of days with better than category II air quality in one year.

2. Amount of emission

This part includes the emission summary, industrial emissions summary, residential emission summary, air pollution control measures description、total emissions (of both industrial and residential emissions), industrial emissions, residential and other emissions, total amount of sulfur dioxide (SO2) emission, amount of industrial sulfur dioxide (SO2) emission, amount of residential and other sulfur dioxide (SO2) emission, soot emissions, industrial fume emissions, residential and other exhaust soot emissions, industrial dust emissions, the total consumption of coal, residential and other coal consumption, industrial coal consumption, fuel coal consumption、raw coal consumption、fuel oil consumption and etc.

The definition of the terms can be found at Word Explanation. (In Chinese only but will be translated into English soon.)

NOTE: As the government environmental reports give sporadic disclosure of total emission, residential and other emission, and total coal consumption; the Air Pollution Map has gaps on these three indicators.

3. List of non-compliant enterprises

The non-compliant enterprises listed on China Air Pollution Map are those that have been found violating emission standards or breaking procedural legal requirements such as EIA.

ATTENTION: The list is a compilation of records of violation and it does not necessarily reflect any given company’s current status of compliance. Please note that the year of violation is clearly marked out with each record.

Rankings

Rankings

Website users will be able to cross compare the levels of various air pollutants and the amount of air emission in different provinces and cities. They can also choose to view the rankings of air quality or air emission of cities in a given province. The ranking means to help users gain a better understanding of the air quality in their own region.

The data comes from reports made by central and local government agencies (mostly environmental agencies).

Air quality ranking can be done between all the municipality leveled cities and cities of a given province.

Users can view the rankings of the following data.

1. Annual average daily concentration of sulfur dioxide, nitrogen oxides, carbon monoxide, inhalable particulate matter.

2. Air pollution index (API)

3. amount of annual average dustfall, concentration of total suspended particulate, rain pH and acid rain frequency.

Air emission ranking can be done between all the provinces, municipality leveled cities and cities of a given province.

Users can view the rankings of the following emission data.

1. Total amount of emission, industrial emission, residential and other emission;

2. Sulfur Dioxide (SO2) including total amount of sulfur dioxide emission, industrial sulfur dioxide emission, residential and other sulfur dioxide emission;

3. Fume Emission Rankings including total amount of fume emission, amount of industrial fume emission, amount of residential and other fume emission;

4. Amount of industrial dust emission;

5. Coal and Oil Consumption including total coal consumption, residential and other coal consumption, industrial coal consumption, industrial bunker coal consumption, industrial raw coal consumption and industrial fuel oil consumption.

Public disclosure of environmental information is the prerequisite for effective public participation; therefore, we have created an “environmental transparency index” (or ETI) to evaluate and rank the responsible environmental protection bureaus in each region on the quality of their information disclosure. The index is based on the level of disclosure of information and data on air quality, air emission and sources of air pollution.

ATTENTION: As the Phase I of the Map covers only 15 provinces of the south China, the ETI is not available so far.
