Comment What's your problem with the Montreal Protocol? (Score 4, Informative) 577
I hope this is sarcasm, because the Montreal Protocol is widely hailed as one of the greatest successes in international cooperation and pollution control. As a result of the treaty, ozone-depleting chemicals in the atmosphere (as measured in equivalent chlorine) have declined by 10%, and the ozone hole over Antarctica is poised to have resorted by 1 million square km (of a peak of 25 million square km) by 2015.
Really, the only failure of the Montreal Protocol was the promotion of HCFC-22 which does less ozone damage but is a major greenhouse gas. (It's being phased out for more ozone-safe refrigerants, but it'll be up there for centuries.)
Does anyone remember the introduction of catalytic converters for cars? What was it we were told? We were told the converters would convert the noxious emissions into harmless water...and carbon dioxide.
Well, when the alternative is carbon monoxide, unburned gasoline, and NOx, I think we'll take the CO2 and water. But just because it's non-toxic doesn't mean that it's not a pollutant.
