Protecting the ozone layer is protecting the blue sky and protecting life on earth. Since 15 september, what is the ozone layer? "knowledge questions and answers are on fire." the event, which will last for half a month, will promote knowledge of ozone layer protection through online fun questions and answers, and participants will have the opportunity to win 200 film vouchers worth $50。
On 16 september 2025, the 31st international day for the protection of the ozone layer and the fortieth anniversary of the adoption of the vienna convention for the protection of the ozone layer, this year under the theme “from science to global action”. The ozone layer is a stratosphere about 15-25 km from the ground, which brings together 90 per cent of the ozone in the atmosphere, absorbs more than 90 per cent of the harmful uv in solar light, and is the earth's “natural sunscreen”。
The hole in the ozone layer is one of the major challenges facing all humankind. Forty years ago, the international community agreed to the vienna convention for the protection of the ozone layer, which launched a global “symmetrical” operation. As a result of persistent efforts, 99 per cent of ozone-depleting substances had been successfully phased out and the antarctic ozone layer had been healing, with significant health and climate benefits。
China has actively contributed to the implementation of regulatory responsibilities and the implementation of commitments under international conventions. In 1989 and 1991, respectively, we signed the vienna convention for the protection of the ozone layer and the montreal protocol on substances that deplete the ozone layer, and subsequently accepted all amendments to their framework, enacting and implementing various domestic regulations and regulatory policies, such as the regulations on substances that deplete the ozone layer. As a result of our tireless efforts, our country has cumulatively phased out some 628,000 tons of ozone-depleting substances, accounting for more than half of the phase-out in developing countries, while avoiding cumulatively 26 billion tons of carbon dioxide equivalent greenhouse gas emissions, with significant benefits for climate change mitigation。
To advance ozone layer protection, jiangsu has been working. Between 2007 and 2018, the department of eco-environment of jiangsu province was involved in the first and second phases of the capacity building project to enhance local ods phase-out compliance, which contributed significantly to the construction and human capacity-building of ods management systems throughout the province. A three-phase project to strengthen local capacity-building for compliance with the montreal protocol in jiangsu province is currently under implementation, through which a long-term provincial compliance management mechanism is being explored。
