September 16 is observed every year as the International Day for the Preservation of the Ozone Layer. This day marks the anniversary of the Montreal Protocol signing in 1987, an important global agreement to protect the ozone layer a vital part of our atmosphere that shields the Earth from the sun’s harmful ultraviolet (UV) rays. Without this protection, we would face much higher rates of skin cancer, eye diseases like cataracts, and serious damage to ecosystems and wildlife.
The discovery of the ozone hole over Antarctica in the 1980s raised alarm worldwide. Scientists linked this damage to human-made chemicals called chlorofluorocarbons (CFCs) and similar substances, which were widely used in refrigeration, air conditioning, foam blowing, and aerosol sprays. These chemicals were breaking down the ozone molecules and thinning the layer that protects life on Earth. In response, countries came together and adopted the Montreal Protocol, agreeing to phase out almost 100 ozone-depleting substances such as CFCs, halons, and HCFCs.
The Protocol is one of the most successful environmental treaties ever because of its global reach and strong results. Nearly all countries in the world have signed it, and since its adoption, over 98% of the harmful chemicals have been phased out. This international agreement has put the ozone layer on a path to recovery, with projections estimating its full healing in most parts of the world by the middle of the 21st century somewhere around 2050 to 2066 depending on the region.
While things are improving, protecting the ozone layer remains crucial today because some harmful substances are still in use or can leak into the environment. Furthermore, many of the chemicals phased down, such as hydrofluorocarbons (HFCs), are potent greenhouse gases that contribute to climate change. Therefore, keeping up this protection effort benefits both the ozone layer and the climate.
Companies like Zeus Packaging can support these efforts by avoiding materials and processes that involve ozone-depleting substances. This means choosing safer alternatives in products and equipment, ensuring proper recycling and disposal of refrigerants and foams, working with suppliers who comply with environmental standards, and implementing environmental management systems to track and minimize harmful emissions.
Individuals can also play a role by selecting energy-efficient appliances that do not use dangerous chemicals, properly recycling old cooling equipment, staying informed about ozone-friendly products, and supporting companies and policies committed to environmental protection.

Each year on September 16, the International Day for the Preservation of the Ozone Layer serves as a reminder of how far we have come and the ongoing need to protect this essential shield for the health of our planet and all living things.
