Emission Inventory Activities
An emission inventory is an estimation of the amount of pollutants discharged into the atmosphere that can be broken down by specified source categories in a certain geographical area and within a specified time span (e.g., in a calendar year).
Pollution Mapping Tool
CARB has developed a pollution mapping tool that allows users to locate and view emissions of GHGs and now, for the first time, also includes criteria pollutants from large facilities in California. The tool provides an interactive platform where users can select facilities by name, location, or industrial sector; view their reported emissions using maps, charts and tabular formats; and download data.
