International Day for the Preservation of the Ozone Layer

International Day for the Preservation of the Ozone Layer in
Days to go: 

International Day for the Preservation of the Ozone Layer is an annual observance aimed at raising awareness on the importance of protecting the ozone layer. This essential component of the Earth's atmosphere plays a crucial role in shielding life on our planet from the harmful effects of ultraviolet (UV) radiation. The day not only highlights the significance of ozone layer preservation but also serves as a reminder for continued global efforts towards reducing the production and emission of ozone-depleting substances.

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. In the United Kingdom, the country plays an active role in the implementation of the Montreal Protocol, through the phasing out of ozone-depleting substances and supporting research in the field. The UK has successfully reduced its consumption of controlled substances, contributing to the global effort in combating 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 specifically falls on September 16 each year, providing a platform for individuals, organisations, 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 2020 was 30 Years of Healing the Ozone Together.
  • 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.

Top things to do in the UK for this observance

  • Use reputable sources to gather information about the Ozone Layer specifically in the United Kingdom. Look for scientific articles, government reports, and educational websites or platforms that provide detailed information on the topic.
  • Explore books and articles written by experts in the field of ozone depletion. These publications can provide detailed insights into the causes, consequences, and current status of the ozone layer in the UK.
