The California Almanac of Emissions and Air Quality

This page last reviewed February 7, 2014

BACKGROUND


Each year, the Air Resources Board publishes The California Almanac of Emissions and Air Quality. The Almanac contains 20-year trend summaries of air quality and emissions data for five criteria pollutants: ozone, PM10, CO, NO2, and SO2. Data are summarized for the State as a whole and for the five most populated air basins (South Coast, San Francisco Bay Area, San Joaquin Valley, San Diego, and Sacramento Valley). In addition to information on criteria pollutants, the Almanac provides information on air quality and emissions for the following ten toxic air contaminants: acetaldehyde, benzene, 1,3-butadiene, carbon tetrachloride, hexavalent chromium, para-dichlorobenzene, formaldehyde, methylene chloride, perchloroethylene, and diesel particulate matter. Similar to the criteria pollutant data, the toxic air contaminant data are also summarized for the State and for each of the five most populated air basins.
