Source of data: US EPA (2019). NO x is a precursor for both ground level ozone and secondary PM 2.5 EPA is targeting implementation in the 2027 timeframe while CARB is focusing efforts on phasing in more stringent standards in 2024 and again in 2027 with the hope of aligning with EPA as a national standard.

Gasoline direct-injection (GDI) engines have higher fuel economy compared to the more widely used port fuel injection (PFI) engines. The EPA GHG program is aimed at reducing tailpipe CO 2 emissions. We estimate ozone and SOA formation potential. For our fleet, increases in the fuel economy of 1.6% (0.5−2.4%;
