What is World Ozone Day?
You may see posts around today about #WorldOzoneDay, so we’ve decided to break down the key things you need to know about today in a quick 3 minute read.
World Ozone Day is celebrated each year on the 16th September as designated by the United Nations General Assembly. It focuses on the preservation of the ozone layer and continues to raise awareness about the importance of preventing its depletion. It is also known as the International Day for the Preservation of the Ozone Layer, and this year’s theme is Montreal Protocol - 'Keeping us, our food and vaccines cool.'
What is the ozone layer?
The ozone layer is a natural layer of gas in the upper atmosphere. It protects us and other living things from the harmful ultraviolet (UV) rays of the sun.
What is The Montreal Protocol?
The Montreal Protocol is in short a united global effort that started in 1987 to protect the ozone layer. Since it began it has led to around 99% of ozone-depletion substances being phased out, which is great! Ultimately, because of The Montreal Protocol, the hole in the ozone layer is healing and helping to slow climate change.
Without The Montreal Protocol, fair-skinned people in 2065 in certain regions would experience sunburn in about 5-10 mins from being outside in the summer. -UNEP
It really is one of the most successful environmental agreements in history - it's a humanitarian success story.
What does this year’s theme mean?
This year’s theme of ‘Keeping us, our food and vaccines cool’ highlights how we need to continue to protect the ozone layer while increasing efforts to cut greenhouse gas emissions from the cooling industry. The cooling industry is crucial in making robust food chains, reducing waste and keeping medicines, vaccines, organs etc as viable for long periods of time. By developing cold chain solutions that are more efficient, more climate friendly, and cheaper to buy and operate, cold chains will become more effective and widely available!
It’s worth remembering that the ozone layer is still a fragile shield of gas, so despite the successes of The Montreal Protocol it still has to be protected. If you want to know more about Karshare's stance on sustainability, have a read of our sustainability page here.
