The Earth's protective ozone layer is well on track to recovery thanks to a highly successful environmental agreement which marks its 30th anniversary on 16 September.

The Montreal Protocol on Substance which Deplete the Ozone Layer achieved a near 99 per cent phase-out of ozone destroying substances like chlorofluorocabons (CFCs) which were once commonly used in products ranging like refrigerants and aerosols.

As a result, the ozone layer which protects life on Earth from harmful levels of ultraviolet rays, is on track to recovery to 1980 benchmark levels by the middle of this century in mid-latitudes and the Arctic, and slightly later in the Antarctic.
