The California Air Resources Board (CARB) has released the results of a multiyear study evaluating exhaust emissions from the use of California Reformulated Gasoline (CaRFG) that contains 15 volume percent ethanol (E15). California currently limits the ethanol content of gasoline to 10 percent. SULEV30, ULEV50, ULEV70, and ULEV125).

The levels of these non-fuel-derived gases will likely remain unchanged, even as more drivers transition from gas-powered to electric vehicles. Another important component of emissions is volatile organic compounds (VOCs), a broad classification of carbon-based molecules that are easily vaporized and that can contribute to ozone formation.

The results, published in an open-access paper in the journal Science , suggest that the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted, the authors suggested. Shown in the bottom row are sales data of fuels for mobile sources (from Fig. 1A) and sales data of volatile chemical products.

Using statistical methods, the scientists infer emissions from these data within a radius of about one kilometer of the measurement location. This has been hard to achieve for diesel powered cars, which nowadays mostly rely on selective catalytic reduction due to the high air to fuel ratio during combustion. —Thomas Karl.

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines. —Saliba et al.
