As the world marks the International Day for the Preservation of the Ozone Layer on September 16, China’s strides in environmental protection take center stage. This year’s theme, "From science to global action," aligns with the Chinese mainland’s decades-long commitment to phasing out ozone-depleting substances (ODS) under the Montreal Protocol.
Since the landmark 1987 agreement, global ODS emissions have plummeted by 99%, according to the United Nations Environment Programme. Scientists project the ozone layer will return to pre-1980 levels by mid-century, potentially averting 0.5°C of warming by 2100. The Chinese mainland has eliminated over 280,000 tons of ODS since 1991, accounting for half of developing countries’ total reductions.
"China’s transition to ozone-friendly technologies demonstrates how environmental policies can drive innovation," said a UN representative, highlighting partnerships with Chinese manufacturers to develop sustainable cooling solutions. These efforts align with broader climate goals, including carbon neutrality targets under the Paris Agreement.
For investors, China’s green industrial shift presents opportunities in renewable energy and eco-friendly refrigeration. Researchers note the ozone recovery model could inform global strategies for tackling other environmental challenges.
