To commemorate the signing of the Montreal Protocol, the United Nations (UN) established September 16 as the International Day for the Preservation of the Ozone Layer (World Ozone Day) in 1994. The Montreal Protocol, signed on September 16, 1987, aims to phase out the production and use of ozone-depleting substances globally. On the 30th World Ozone Day in 2024, China's Ministry of Ecology and Environment released an announcement, reaffirming the country's commitment to the Montreal Protocol and its Kigali Amendment, as well as the determination to establish a comprehensive hydrofluorocarbons (HFCs) lifecycle management system and strengthen international cooperation to tackle global climate challenges.

Since joining the Montreal Protocol in 1991, China has eliminated 628,000 tonnes of ozone-depleting substances, accounting for more than half of the total reduction by developing countries. Over the years, China has prevented the equivalent of more than 26 billion tonnes of CO2 emissions, contributing significantly to the recovery of the ozone layer and the fight against climate change.

In October 2016, parties to the Montreal Protocol adopted the Kigali Amendment, which aimed to regulate and reduce HFCs, the potent greenhouse gases that contribute to global warming. China officially accepted the Kigali Amendment in April 2021, marking a new chapter in the country's dual effort to protect the ozone layer and combat climate change under the framework of the Montreal Protocol.
Scientific assessments suggest that global adherence to the Kigali Amendment's regulations could prevent up to 0.5 degrees Celsius of global temperature rise by the year 2100, making a significant contribution to the global climate targets set by the Paris Agreement.
China's approach to HFC reduction is multifaceted. The country has incorporated HFCs into its regulatory framework, with new regulation effective from March 1, 2024, providing a solid legal foundation for controlling and reducing HFC emissions. Additionally, China is formulating detailed plans to continue fulfilling its obligations under the Montreal Protocol, with clear timelines and policy measures aimed at strengthening HFC lifecycle management.

Furthermore, a strict quota and licensing management system has been put in place to control the total volume of HFCs. China has also enhanced oversight of HFC imports and exports, actively combating illegal trade to contribute to global climate governance. By boosting daily supervision and conducting special enforcement actions, China has fostered a robust compliance environment, continuously improving its regulatory levels.
Finally, China emphasizes technological advancements, particularly in research and development of HFC alternatives for industries like automotive and home appliances. The country actively encourages the use of natural refrigerants, promoting industrial upgrades and high-quality development.
In conclusion, China has made significant progress in fulfilling its obligations under the Montreal Protocol and the Kigali Amendment, demonstrating its commitment as a responsible global leader. China will continue enhancing regulation and scientific research, advancing green and low-carbon development while working with the international community to tackle global climate challenges.
