Title: Study to develop projected activity for "non-road mobile" categories in California, 1970-2020.

Principal Investigator / Author(s): Puri, Anil K

Contract Number: 92-732


Research Program Area: Emissions Monitoring & Control, Economic Analysis

Topic Areas: Mobile Sources & Fuels


Abstract:

The California Air Resources Board (ARB) maintains models to track and forecast emission trends for the State. The models are also used by Air Quality Management Districts (AQMDs) and Air Pollution Control District (APCDs) to demonstrate that their air quality management plans will achieve required pollution reductions. Emission forecasts, in turn, are based upon measures of past and projected economic activity across the State and at the county levels. The accuracy of emission forecasts and control measure effectiveness thus depends critically on estimates of the underlying economic activity.

This report presents estimates and projections for 21 categories of non-road mobile sources of pollution in California and its 58 counties. The historical estimates are for the period 1970-1992 and projections for 1993-2020. The categories include: farm equipment, aircraft, locomotives, ships, commercial and recreational boats, lawn and garden equipment, off highway recreational motor vehicles and non-farm equipment.

The estimates and projections are summarized in 21 graphs and 21 tables for the State and 58 counties.
