Mandatory regional criteria pollutant reduction targets will be established in the 2016 State Implementation Plans (SIPs) with expected reductions on the order of 90% below 2010 levels in the South Coast and similar reductions in the San Joaquin Valley by the year 2032. This is particularly true for fleets that have a central fueling hub.

As a result, the market share of GDI-equipped vehicles has increased dramatically over the past decade and is expected to reach 50% of new gasoline vehicles sold in 2016. We estimate ozone and SOA formation potential. We use the data to quantify the effects of engine technology, emission standards, and cold-start on emissions.
