However, the use of CFT resulted in a remarkable reduction in carbonyl emissions in comparison with using DF. lower ozone formation potential of the carbonyl compounds present than DF under the identical operating conditions. There was no significant difference in the profiles of total carbonyl emissions between CFT and DF. CFT had 16.5–44.1%

the combined heating effect of long-lived greenhouse gases added to the atmosphere by human activities has increased by 29% since 1990, the index year used as a baseline for comparison. It also includes several chemicals known to deplete Earth’s protective ozone layer, which are also active as greenhouse gases. in 2010—i.e.,

Despite their limitations, GWPs are widely used for comparison among long-lived gases, forming the basis for worldwide political agreements on climate and carbon trading. And hydroxyls drive long chains of reactions involving other common gases, including ozone. —Drew Shindell. —Drew Shindell.

In the months following a pulse of NO x in the upper atmosphere, ozone production is stimulated causing a short-term warming. The corresponding reduction in CH 4 , which is an important ozone precursor, leads to a long-term reduction in ozone. —Stratton et al. Many other factors have less quantifiable impacts.
