Every year on September 16, we observe the International Day for the Preservation of the Ozone Layer, which was established by the United Nations in 1994 to commemorate the signing of the Montreal Protocol in 1987. This historic agreement marked a turning point for environmental protection, as the signatory countries committed to phasing out substances responsible for ozone depletion, including chlorofluorocarbons (CFCs).
Thanks to this collective effort, the ozone layer is now showing clear signs of recovery, proof that cooperation and regulation can deliver tangible results.
This day is more than an environmental awareness event: it is an opportunity to reflect on the role that businesses, institutions, and citizens alike can play in building a more sustainable future.
The ozone layer: our invisible common good
The ozone layer lies in the stratosphere, between 15 and 35 kilometers above the Earth’s surface, and performs a vital function: it absorbs most of the sun’s ultraviolet radiation, protecting life on our planet. Without this “natural shield,” the consequences for human health and ecosystems would be severe: more cases of skin cancer and cataracts, reduced agricultural productivity, and widespread damage to both land and marine environments.
In the 1970s and 1980s, heavy use of CFCs and other chemicals in aerosols, refrigerants, and industrial processes led to the thinning of the ozone layer and the formation of the infamous “ozone hole” over Antarctica. The international response, through the Montreal Protocol, indicates how global cooperation can produce real results: the gradual phase-out of these substances has already led to signs of recovery, with scientists predicting a return to pre-1980 levels by the middle of this century.
From ozone protection to chemical management
So what does ozone protection have to do with our everyday reality as consultants and businesses working under the European regulatory framework, particularly REACH and CLP?
The connection is clear: it’s all about the responsible management of chemicals. If the Montreal Protocol marked the end of an era of uncontrolled use of ozone-depleting substances, today, regulations like REACH (Regulation EC No. 1907/2006) and CLP (Regulation EC No. 1272/2008) play an equally crucial role in ensuring that products placed on the market are safe for human health and the environment.
The regulatory legacy of the Montreal Protocol
The Protocol taught us that international regulation is not an obstacle to economic growth-it can actually drive innovation. Industries had to replace banned substances with safer alternatives, paving the way for new technologies.
In the same way, REACH and CLP now encourage companies to improve their processes, gain deeper knowledge of the substances they use, and communicate transparently across the supply chain. The goal remains the same: reduce risks and protect future generations.
REACH, CLP, and environmental protection
Although their focus differs, both European regulations have a strong environmental dimension:
- REACH requires substances to be registered and assessed, driving the gradual phase-out of the most hazardous ones (SVHCs – Substances of Very High Concern).
- CLP ensures that classification and labeling are clear, so that risks are effectively communicated to users.
Both share the same mission as the Montreal Protocol: preventing harm to health and the environment before it becomes irreversible, while placing clear responsibilities on those who produce, import, or use chemicals.
As the Montreal Protocol succeeded thanks to international collaboration, the effectiveness of European regulations depends on a shared commitment between institutions, businesses, and consultants.
In summary, the International Day for the Preservation of the Ozone Layer is not just a symbolic anniversary; it is a concrete reminder that regulation works when applied with seriousness and responsibility.
If the Montreal Protocol were to demonstrate that harmful substances can be replaced with safer alternatives, today REACH and CLP ensure that this principle is applied on a daily basis- transforming a lesson from the past into a real commitment for the future.
