Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.

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. The trend towards smaller engine cores with smaller mass flow rates in the core stream, presents new opportunities for emissions control. increase in block fuel burn.

NO x is a precursor for both ground level ozone and secondary PM 2.5 It is important to state that there are several technology paths to achieve these levels of emissions, and some of them can simultaneously lower greenhouse gas emissions, such that the NO x reductions do not compete with the CO 2 reductions.

That ranks the effects of soot ahead of methane, an important greenhouse gas. Particle traps filter out soot particles from exhaust fumes. 1990; Anisimov, 2007] and chemical production of ozone in already-polluted locations [Jacobson, 2008b]. These three gases are all greenhouse gases, and ozone is a surface air pollutant.

Everyone solemnly agreed, again, to follow the science, which has shown in exhaustive detail that humanity will suffer from heat, fire, floods, and droughts if the world warms beyond 1.5° Yet if countries continue on their present course, the world will likely have warmed by 2.7° C above pre-industrial levels.

BNSF has been operating four liquefied natural gas yard locomotives in downtown Los Angeles since the mid-1990s. NO x helps create ground-level ozone, or smog. ARB Staff Presentation.
