At cruising altitude, airplanes emit a steady stream of NO x into the atmosphere, where the chemicals can linger to produce ozone and fine particulates. Due to its size, any SCR system will likely need to be housed in the aircraft body, potentially making it most suitable for future hybrid- or turbo-electric aircraft designs.

Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles.

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). One hybrid electric vehicle (HEV) equipped with a PFI engine was also used. SULEV30, ULEV50, ULEV70, and ULEV125).

Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. All totaled, engine heat accounts for 26% of the fuel consumed, and exhaust heat accounts for another 24%.
