Map of Annual Total Pollutant On-road Emissions for 2030 (tons/year)

PAG Air Quality staff completed the gridded on-road emissions mapping for the transportation network for 2000 and for 2030 (shown below). Emissions were calculated using  500 meter grids.  As expected, much of the pollution is emitted along the freeways and major arterial streets due to heavy traffic and at intersections, where cars idle. Detailed information with gridded maps for individual pollutants can be found in the 2000 On-Road Mobile Source Emissions Inventory.
