Opportunity Wasted Methyl Bromide: Our best chance to Reduce Ozone Depletion Now

The impact of methyl bromide on the ozone layer is unusually severe and rapid. Bromine, the ozone-depleting element found in methyl bromide, is nearly 60 times more effective at destroying ozone than the chlorine found in CFCs.9 This means that even though its atmospheric lifetime is quite short (a little over a year)31, the immediate impact of changes in methyl bromide emissions on the ozone layer is very high compared to other chemicals.
