Summary:

The effect of the introduction of low-emission vehicles on potential air quality improvement in the Los Angeles area was predicted using a three-dimensional airshed simulation model. The simulations were based on ozone concentration estimates made on the basis of data released by the California Air Resources Board concerning projected quantities of emissions from various sources in 2010. Analyses were made of three scenarios. One assumed that LEV, ULEV and ZEV regulations were enforced as planned, a second assumed that these planned regulations were modified; and a third assumed that emission levels from various sources were reduced in line with the goals of the Air Quality Management Plan formulated by the South Coast Air Quality Management District. The results indicate that:The results also show that lowering the ROG level of vehicular emissions has a large effect on reducing the ozone concentration. In contrast, a reduction in NOx emissions has a smaller effect, and some of the data suggest that the ozone concentration might conversely increase under certain conditions. In 2010, when the contribution of vehicular emissions to the ozone level will be smaller, the simulation results suggest that a further reduction in the ozone concentration will most likely require a substantial decrease in the ROG level from non-vehicular emission sources
