California Air Resources Board

The California Air Resources Board (CARB) collects data on the amount of pollutants emitted from different type of sources, as well as the concentration of these pollutants in the air.  The below tools track emissions and air concentrations of criteria pollutants, such as particulate matter and ozone, as well as greenhouse gases and toxic air contaminants.

AQview

CARB is launching a new air quality viewer called AQview, which will focus on displaying air quality data collected in AB 617 communities.

Emission Inventories

An emission inventory is an estimation of the amount of pollutants discharged into the atmosphere organized by source categories.

Air Pollution Mapping Tool

CARB has released an updated version of this tool that includes emissions data for toxic air pollutants along with previously available criteria pollutants and greenhouse gases (GHG) from large facilities in California.

Air Quality Data Statistics

CARB, the United States Environmental Protection Agency, and local air districts measure the concentration of pollutants in the air and make the data available to the public.
