Climate Change

Greenhouse gases like carbon dioxide (CO2) are generally analyzed separately from the "traditional" air pollutants, since they are most closely related to energy and fuel consumption. However, some tools may be common to both greenhouse gas and air quality analysis. The California Air Resources Board's (ARB) EMFAC model, for instance, produces estimates of CO2 emissions and fuel usage as well as the more traditional mobile source emissions.

The California Air Resources Board prefers an approach based on fuel usage, similar to what was used for the California Greenhouse Gas Emission Inventory.
