World Ozone Day – 16 September 2020

In 1994, the United Nations General Assembly (UNGA) proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer. A group of twenty-four countries came together and signed the Montreal Protocol on substances that deplete the ozone layer.

The principal aim of the Montreal Protocol is to protect the ozone layer by taking measures to control global production and consumption of substances that deplete it, with the objective of elimination on the basis of developments in scientific knowledge and technological information.

Ozone-Depleting Substance(s)

  • Chlorofluorocarbons (CFCs)
  • Hydrochlorofluorocarbons (HCFCs)
  • Halons
  • Methyl bromide
  • Carbon tetrachloride
  • Methyl chloroform

The amount of damage done to the ozone layer depends on the type of ozone depleting substance or chemical used. The negative volume of a chemical depends amongst other factors on how long the chemical continues in the atmosphere before being broken down itself. The ozone depleting potential of a chemical gives a measure of the ability to destroy stratospheric ozone. Ozone depletion leads to excessive UV-B radiation. Excessive UV-B radiation in turn leads to:

  • More skin cancers and eye cataracts.
  • Less productivity of plants.
  • Loss of immunity to diseases.
  • Adverse effects on plastics.

South Africa is party to both the Vienna Convention for the protection of Ozone Layer and the Montreal Protocol on Substances that deplete the ozone layer. South Africa has previously hosted celebration events at various provinces to raise awareness. This year the event will be held virtually.

The Department of Environment, Forestry and Fisheries informed that the Executive Secretary of the Montreal Protocol, Ms Tina Birmpili and the Minister of Environment Forestry and Fisheries, Ms Barbara Creecy will address the delegates during the World Ozone Day celebration.

The theme for this year’s celebration is: “Ozone for Life” with a supporting slogan “35 years of ozone layer protection”.

The event will be held on 16 September 2020 at 10h00 - 12h00.
