South Africa reflects on World Ozone Day 2025 and its commitment to a healthier atmosphere

As countries around the globe come together to celebrate World Ozone Day 2025, South Africa stands at the forefront, reflecting on its journey towards ozone protection.

Observed annually on September 16, this day serves as a vital reminder of the imperative to safeguard the ozone layer - an invisible shield in the Earth’s stratosphere that plays a crucial role in absorbing harmful ultraviolet rays from the sun. This layer is not just a barrier; it protects humans, animals, plants, oceans, and entire ecosystems from devastating consequences.

Without the ozone layer, the implications would be dire. Higher instances of skin cancers and cataracts, agricultural failures, biodiversity loss, and long-term repercussions for our oceans are just a few of the potential catastrophes that would result.

In light of these significant risks, Dr Dion George, the Minister of Forestry, Fisheries and the Environment, remarked, “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, as many of the ozone-depleting chemicals are potent greenhouse gases.”

The theme for World Ozone Day 2025, “From Science to Global Action”, resonates deeply with global historical efforts, the department said. It highlights the triumph of international collaboration in the late 20th century when countries responded to alarming discoveries about ozone depletion caused by human-made chemicals. This collective awareness and action ultimately led to the 1987 signing of the Montreal Protocol on substances that Deplete the Ozone Layer, a milestone that brought nations together under the Vienna Convention for the Protection of the Ozone.

In South Africa, tangible progress has been made in this area. The country has effectively phased out chlorofluorocarbons (CFCs) - widely used in air conditioning and refrigeration - and is actively working to reduce halons used in fire extinguishers. Moreover, there is an ongoing phase-down of hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs), which are prevalent in various sectors, including refrigeration and air conditioning.

Progress also unfolds within the Ventilation Refrigeration Air-conditioning and Heat Pump industries as they explore safer refrigerant options and invest in sustainable technologies. Training employees in best practices and closely monitoring refrigerant use demonstrates a commitment to ozone preservation. Furthermore, an increasing number of individuals and communities are making conscientious choices that help protect the ozone layer - by opting for energy-efficient appliances, servicing their air conditioning and refrigeration units, and disposing of old equipment responsibly.

Moreover, South Africa's commitment to reducing carbon emissions aligns closely with its ozone protection initiatives, forming part of a broader transition towards a low-carbon, climate-resilient economy. Recently, Minister George unveiled the draft National Greenhouse Gas Carbon Budget and Mitigation Plan Regulations, ensuring adherence to international obligations while cementing the country’s path to sustainable development. Stricter regulations for power stations, such as those governing Eskom, further underline the balance between energy security and environmental protection.

Yet, as Minister George emphasised, “Much more needs to be done and each one of us plays a part in securing a healthier atmosphere and the recovery of the ozone layer, not only for the present but for the benefit of future generations.”The department added the call to action remains clear: individual and collective efforts are paramount for a thriving planet.
