MECA emissions inventory & air quality modeling shows potential benefits of national cleaner trucks initiative at CARB limits

Green Car Congress

The modeled 2028 base year 8-hour ozone design values were found to be above the 70 ppb NAAQS for 75 monitoring locations. By 2035, 46 states will be in attainment with the 2015 ozone NAAQS of 70 ppb (only counties in California and Utah remain in nonattainment). ppb in the east (Atlanta, GA). Source: MECA.

Furthermore, myclimate accounts for other warming effects of aircraft emissions (through changes in the ozone layer, initiation of contrails, formation of cirrus clouds, etc.) by adding an amount that corresponds to the direct portion of emissions. (A A documentation for the myclimate calculator includes other aspects of the method used.).
