Global ozone layer "remains at risk"
Conflicting reports on the health of the world's ozone shield emerged as the UN marked international ozone layer preservation day on Tuesday. The UN environment programme issued a statement noting "first signs of recovery" just days after British scientists reported that the Antarctic ozone hole had reached record proportions for this time of year. UN calls for action against illegal trade in chlorofluorocarbons (CFCs) were echoed by a London-based NGO, which claimed "strong evidence" of EU-produced CFCs appearing on the black market in developing countries.
