The ozone layer is a natural layer of gas in the stratosphere that protects all life on Earth from the sun’s harmful UV rays. This is a vital defense mechanism for our planet, particularly in the wake of global warming and the climate crisis. So, we have to ask: What is the most important information you need to know about this year’s International Day for the Preservation of the Ozone Layer?

👉 Official Name: International Day for the Preservation of the Ozone Layer
💚 Cause: Promote the phasing out of ozone-depleting substances and protect our natural planet, as well as human health

Keep on reading to find out all the important information about International Day for the Preservation of the Ozone Layer at a glance, including its big picture, why it’s important, and how you can get involved. We’ll then share its brief history, three interesting facts about it, its future dates, and how you’ll never miss any important awareness event again.

The Most Important Information About International Day for the Preservation of the Ozone Layer at a Glance

1️⃣ The big picture: The International Day for the Preservation of the Ozone Layer is an initiative of the United Nations to celebrate the achievements made to date to protect the ozone layer and to encourage further action for people, the climate, and our planet. 

2️⃣ Why it is important: Ozone-depleting substances such as chlorofluorocarbons (CFCs) and halon gasses were traditionally used in numerous common items such as refrigerators and deodorants. But, thanks to the Montreal Protocol, global emissions of these substances have decreased by 99% since the 1980s. However, while the ozone layer is slowly healing, protecting us from the sun’s harmful UV rays, it is still under pressure. In fact, experts predict that the ozone hole won’t fully close until at least 2060 and that also depends on our ability to tackle climate change, pollution, and global warming.

3️⃣ How you can get involved: You can get involved in International Day for the Preservation of the Ozone Layer by spreading awareness through social media, hosting your own awareness event, joining advocacy efforts to protect our planet, or educating yourself on the importance of the ozone layer: 

1. Social Media Awareness: Spread the word about the importance of the ozone layer and encourage action to protect it on your social media platforms by using hashtags such as #InternationalDayForThePreservationOfTheOzoneLayer, #WorldOzoneDay, and #PreservationOfTheOzoneLayer
2. Localized Events: Get your local community involved in this day by organizing your own event. For example, you can hold a conversation starter to discuss the ozone layer in relation to climate change or you can set up an educational event to celebrate the Montreal Protocol. 
3. Advocacy: Consider donating to, advocating with, and volunteering for organizations and charities that fight to preserve the ozone layer and protect our planet from the threat of climate change, such as the Clean Air Task Force, The Climate Coalition, and Cool Earth.
4. Educate yourself: Many people are unfamiliar with the role of the ozone layer in protecting our planet. So, International Day for the Preservation of the Ozone Layer is the perfect time to dig into books and websites to better understand the ozone layer.

A Brief History of International Day for the Preservation of the Ozone Layer

When was this event established: International Day for the Preservation of the Ozone Layer was founded in 2000 by the United Nations General Assembly to commemorate the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987. This event is seen as a landmark in environmental policy-making because it was designed to prevent a global problem rather than fix it.

How has it developed since then: Today, the International Day for the Preservation of the Ozone Layer is dedicated to raising awareness of the ozone layer and what we can do to protect it. There is a different theme every year, with past themes including “Advancing Climate Action”, “Global Cooperation Protecting Life on Earth”, and “Keeping Us, Our Food, and Vaccines Cool”. 

3 Interesting Facts About International Day for the Preservation of the Ozone Layer

1. Significance of the Montreal Protocol: In order to protect our ozone layer, the Montreal Protocol requires the control of more than 100 chemicals in several different categories. For each group of chemicals, the Treaty sets out a timetable for the phase-out of the production and consumption of these substances, with the aim of eventually eliminating them completely. 
2. An interconnected system: Rockström, alongside others, created the planetary boundaries model in 2009, providing a useful framework to assess our planet’s health by encompassing vital factors such as freshwater availability, biodiversity, land use, and climate. With six of the boundaries already crossed, this reminds us of the stark reality that we can’t solve one problem without addressing all the issues as our planet relies on the interconnectedness of these elements to prosper. 
3. The vital role of Indigenous communities: Despite only making up less than 5% of the human population, Indigenous communities protect at least one-quarter of the world’s land and seas, as well as 80% of its biodiversity through direct action and knowledge sharing. These are the people we need to listen to when it comes to protecting the Earth as a whole. In fact, studies show that when Indigenous peoples have the right to govern their land, forests are better protected and biodiversity increases.
