There is some smuggling of illegal CFCs, but it is minor compared to the damage that has been averted. The ozone layer is currently in its most vulnerable state. Ozone depleting chemicals are expected to peak in the stratosphere around the year 2000. There's a delay between the production peak and the damage peak, because it takes years for a newly released CFC molecule to work its way up to the ozone layer. The springtime Antarctic ozone hole continues unabated.
Ozone depletion is worse over the South Pole than anywhere else.
The vast ozone hole that opens there every October in the southern spring shows no sign of closing yet. The ozone layer will slowly recover over the next 50 years. That's how long the chlorine already up in the stratosphere will last. Few policy options are available to enhance the recovery of the ozone layer. We've already done about all we can do.
