International Day for the Preservation of the Ozone Layer

International Day for the Preservation of the Ozone Layer

The International Day for the Preservation of the Ozone Layer is a global annual observance that underscores the collective responsibility to protect this essential component of the Earth's atmosphere. The ozone layer plays a crucial role in shielding life on our planet from the harmful effects of ultraviolet (UV) radiation. The day serves as a reminder for continued global efforts towards reducing the production and emission of ozone-depleting substances, highlighting the significance of this preservation.

The United Nations General Assembly established the International Day for the Preservation of the Ozone Layer in 1994, commemorating the signing of the landmark Montreal Protocol on Substances that Deplete the Ozone Layer in 1987. The United Kingdom plays an active role in implementing the Montreal Protocol by phasing out ozone-depleting substances and supporting research in the field. The UK has successfully reduced its consumption of controlled substances, contributing to the global effort to combat ozone layer depletion and protecting public health, ecosystems, and climate.

In observance of the International Day for the Preservation of the Ozone Layer, events and activities are held across the UK to raise awareness of this critical issue. These include educational workshops, public lectures, and campaigns that focus on topics such as the ongoing efforts to phase out ozone-depleting substances, the impact of climate change on the ozone layer, and possible measures to mitigate these challenges. International Day for the Preservation of the Ozone Layer always falls on September 16 each year, providing a platform for individuals, organizations, and government bodies to engage in environmental conservation and promote sustainable practices.

Facts about the Ozone Layer

• The theme for International Day for the Preservation of the Ozone Layer in 2025 was Montreal Protocol: Advancing Climate Action. In 2024 the theme was Montreal Protocol: fixing the ozone layer and reducing climate change.
• The natural level of ozone in the stratosphere is a result of a balance between sunlight that creates ozone and chemical reactions that destroy it.
• The thinning of the ozone layer is caused by chemicals, such as chlorofluorocarbons (CFCs), carbon tetrachloride, halons, and others. These chemicals -- often used in refrigeration, air conditioning, packaging, insulation, aerosols, and so on -- release chlorine and bromine when they come in contact with sunlight. These elements then deplete the ozone layer.
• The depletion of the ozone layer was first observed in the 1970s, and the term ozone hole was coined in 1985 after a significant decrease in ozone concentrations was reported in the stratosphere over Antarctica.
• Researchers from the University of Leeds in the UK discovered in 2018 that the world's supply of dichloromethane, an ozone-depleting substance not regulated by the Montreal Protocol, was unexpectedly increasing.
