You sure? "These standards specifically restrict emissions of carbon monoxide (CO), oxides of nitrogen (NOx), particulate matter (PM), formaldehyde (HCHO), and non-methane organic gases (NMOG) or non-methane hydrocarbons (NMHC). The limits are defined in grams per mile (g/mi)" https://en.wikipedia.org/wiki/...

Well, except that in this case it increases fuel efficiency because they run leaner in order to get better MPG which also reduces CO2, Hydrocarbon, and CO emissions at the cost of increasing NOx emissions. The more I look into it, it seems that the problem is that these engines run too efficiently to achieve high enough temperatures to activate the catalyst to scrub the NOx. So the EPA is basically asking to burn off more fuel in order to heat up the catalyst. I'm sure that would reduce NOx emission as a ratio with fuel burned, but I'm not sure that the absolute level of NOx emission would be lower in that mode. Either way, calculating emissions per gallon instead of per mile seems dubious to me. http://www.rx8club.com/attachm...
