This October 2001 report by the Environmental Investigation Agency is called "Unfinished Business - The Continued Illegal Trade in Ozone-Depleting Substances and the Threat Posed to the Montreal Protocol Phase-out".
The introduction states, "...the present state of the ozone layer gives cause for concern and has dire
implications for ecosystems and human health. Every year the ozone hole over Antarctica grows bigger, and a similar hole is predicted to develop over the Northern Hemisphere during the next twenty years.
Initial predictions for full recovery by 2050 now seem optimistic, and the Montreal Protocol process continues to be undermined by the illegal trade in ODS. The Environmental Investigation Agency (EIA) has been tracking the black market in chlorofluorocarbons and halons since the mid- 1990s and has presented detailed information on the main routes, smuggling methods and companies involved to the Parties to the Montreal Protocol and to enforcement agencies in many countries."
