World Ozone Day: Compliance and Enforcement Essential
George George Idowu
World Ozone Day, celebrated every year on September 16th, marks a pivotal moment in the global effort to protect the ozone layer.
This year, the theme “Ozone for Life: 35 Years of Global Cooperation” commemorates the 35th anniversary of the Vienna Convention for the Protection of the Ozone Layer and highlights the critical role of international collaboration in safeguarding our planet’s protective shield.
The theme reminds us that the ozone layer, while invisible, is vital for life on Earth and that its preservation requires continued and concerted efforts.
World Ozone Day, officially known as the International Day for the Preservation of the Ozone Layer, was established by the United Nations General Assembly in 1994 to commemorate the signing of the Montreal Protocol in 1987. The Montreal Protocol is widely regarded as one of the most successful environmental treaties in history, with universal ratification by all UN member countries. It aims to phase out the production and consumption of ozone-depleting substances (ODS), such as chlorofluorocarbons (CFCs) and halons, which were found to be causing significant harm to the ozone layer.
The ozone layer in the Earth’s stratosphere absorbs most of the sun’s harmful ultraviolet (UV) radiation. Without this protective layer, life on Earth would be exposed to increased levels of UV radiation, leading to higher rates of skin cancer, cataracts, and other health problems, as well as negative impacts on ecosystems, agriculture, and marine life.
The theme “Ozone for Life: 35 Years of Global Cooperation” celebrates the collective action taken by countries worldwide to address the depletion of the ozone layer.
Over the past 35 years, the Montreal Protocol has been instrumental in phasing out nearly 99% of ozone-depleting substances, leading to significant recovery of the ozone layer. This achievement is a testament to the power of international cooperation, as nations worked together to implement effective policies, innovate alternatives to harmful chemicals, and raise public awareness about the importance of protecting the ozone layer.
One of the Montreal Protocol’s key successes is its flexibility in adapting to new scientific findings and technological advancements.
The Protocol has been amended multiple times to include new substances and accelerate phase-out schedules, reflecting a commitment to proactive and evidence-based policy-making. As a result, the ozone layer is on a path to recovery, with projections suggesting it could return to pre-1980 levels by the middle of this century, assuming continued compliance with the Protocol.

However, challenges remain. The illegal trade of banned ozone-depleting substances, the potential impact of climate change on ozone recovery, and the need for continued vigilance to prevent the emergence of new threats underscore the importance of maintaining and strengthening global cooperation.
Last year, World Ozone Day focused on the theme “Montreal Protocol: Keeping Us, Our Food, and Vaccines Cool,” highlighting the Protocol’s contribution to ozone protection, climate mitigation, and public health.
The theme emphasised the importance of the Kigali Amendment to the Montreal Protocol, which aims to phase down hydrofluorocarbons (HFCs), potent greenhouse gases used in refrigeration and air conditioning. By addressing HFCs, the Montreal Protocol protects the ozone layer and contributes to the global fight against climate change.
As highlighted by last year’s theme, the transition to sustainable cooling solutions is vital in ensuring that the Montreal Protocol’s benefits extend beyond ozone protection to encompass broader environmental and health outcomes. Cooling is essential for preserving food, medicines, and vaccines, particularly in developing countries where access to reliable refrigeration can be a matter of life and death.
Thus, by promoting climate-friendly cooling technologies, the Montreal Protocol helps protect vulnerable populations from the impacts of heatwaves, food spoilage, and inadequate vaccine storage.
As we celebrate 35 years of the Vienna Convention and the Montreal Protocol, it is crucial to recognize that the work is far from over.
The ozone layer recovery is a slow process, and continued international cooperation is essential to ensure that progress is maintained and that new challenges are addressed effectively.
Looking ahead, the focus must remain on compliance and enforcement, especially in regions where the illegal trade of ozone-depleting substances persists.
Furthermore, ozone protection efforts must be integrated with broader environmental and climate goals, recognising their interconnectedness. Promoting energy-efficient cooling technologies that do not harm the ozone layer or contribute to global warming can help achieve multiple environmental objectives.
World Ozone Day 2024 is a powerful reminder of the importance of international collaboration in addressing global environmental challenges. The successes of the past 35 years demonstrate what can be achieved when nations come together to protect the planet.
As we reflect on this milestone, let us reaffirm our commitment to preserving the ozone layer and ensuring a safe and healthy future for all life on Earth. The journey is not over, but with continued cooperation and innovation, we can ensure that the ozone layer remains intact for future generations, truly embodying the spirit of “Ozone for Life ”
