On 16 September 2025, South Africa joined nations globally in observing World Ozone Day, officially known as the International Day for the Preservation of the Ozone Layer. Minister Dr Dion George of the Department of Forestry, Fisheries and the Environment led the commemoration, emphasising the importance of protecting the ozone layer from harmful substances like CFCs and HCFCs.
This year’s theme, “From Science to Global Action,” draws attention past scientific discovery and calls for renewed urgency in implementing protective measures.
What Happened
The ozone layer is Earth’s invisible shield in the stratosphere, filtering out most of the sun’s ultraviolet rays to protect ecosystems, human health, animals, plants and oceans. Without this layer, risks include higher rates of skin cancer and cataracts, crop failures, biodiversity loss, and damage to marine life.
South Africa has taken strides: phasing out chlorofluorocarbons (CFCs), reducing use of HCFCs and HFCs in refrigeration, HVAC (heating, ventilation and air-conditioning) and foam sectors, and supporting safer refrigerants and sustainable technologies. Individuals and communities have also begun choosing energy‑efficient appliances, servicing cooling equipment properly, and disposing of old appliances safely.
Official Response
Dr. Dion George stressed that protection of the ozone layer aligns closely with efforts to combat climate change, because many ozone‑depleting substances are also potent greenhouse gases.
“This day is an opportunity to reflect on the importance of ozone protection, while also highlighting it as an important key in the fight against climate change…” said Minister George.
He pointed to recent initiatives that the draft National Greenhouse Gas Carbon Budget and Mitigation Plan Regulations, stricter emission standards for Eskom power plants, and launching programmes to train technicians in safe refrigerant handling.
Community Impact
For many South Africans, the actions taken will translate into long‑term health benefits, more resilient ecosystems, and safer food production. The shift toward sustainable technologies in cooling and better maintenance of appliances helps reduce both ozone damage and carbon emissions.
Communities adopting environmentally friendly practices buying energy‑efficient appliances, servicing their cooling systems, choosing proper disposal—play a part in reducing risks. As awareness grows, so too does the chance of restoring the ozone layer and protecting future generations from the consequences of neglect.
FAQ
- What is World Ozone Day, and why is it observed on 16 September?
World Ozone Day, officially the International Day for the Preservation of the Ozone Layer, is observed on 16 September to mark the signing of the Montreal Protocol in 1987, which commits nations to phase out ozone‑depleting substances. Government of South Africa+1
- Which substances are being phased out or reduced?
South Africa has phased out CFCs, is reducing HCFCs and HFCs, especially in refrigeration, air conditioners, and foam sectors. Government of South Africa
- How does protecting the ozone layer help fight climate change?
Many ozone‑depleting substances are also powerful greenhouse gases. Reducing them helps both ozone recovery and lowers global warming potential. Government of South Africa+1
