China Exceeds Phase Compliance Targets for Ozone Protection Agreement
China has surpassed its phased compliance goals for the Montreal Protocol, significantly reducing ozone-depleting substances and contributing to global environmental governance.

On International Ozone Layer Protection Day, China announced it has exceeded its phased compliance targets for the Montreal Protocol, having eliminated over 720,000 tons of ozone-depleting substances and achieved substantial reductions in hydrofluorocarbons (HFCs). This effort, which includes destroying over 17,000 tons of trifluoromethane annually, significantly contributes to global…
Imagine the Earth has a special blanket in the sky called the ozone layer that protects us from the sun's harmful rays. Some old chemicals we used to use poked holes in this blanket. China promised to stop using these chemicals and has done an even better job than they said they would, helping to fix the blanket and also reducing other gases that make our planet too warm, like turning down the Earth's thermostat.
Analysis
China's Montreal Protocol Achievements
China has demonstrated a strong commitment to environmental protection by not only meeting but exceeding its phased compliance targets under the Montreal Protocol. Since joining the protocol, the nation has implemented a comprehensive strategy involving economic, technical, legal, and administrative measures. This multi-faceted approach has led to the cumulative elimination of 720,000 tons of ozone-depleting substances (ODS) in production and consumption. This figure represents more than half of the total ODS eliminated by all developing countries, highlighting China's significant role in the global effort to protect the ozone layer.
Hydrofluorocarbon Reduction and Climate Impact
A key aspect of China's recent success lies in its stringent control over hydrofluorocarbons (HFCs), which, while not depleting the ozone layer, are potent greenhouse gases. Since 2024, China has rigorously managed the production and consumption of HFCs. The reported figures indicate that the cumulative production of HFCs has been reduced by over 1.185 billion tons of carbon dioxide equivalent (CO2e) below the national compliance target. Similarly, consumption has been reduced by more than 759 million tons of CO2e below the target. These reductions are substantial and directly contribute to mitigating global warming.
Beyond Compliance: Destruction and Greenhouse Gas Mitigation
China's environmental efforts extend beyond mere reduction targets. The country is actively engaged in the destruction of ODS, annually disposing of over 17,000 tons of trifluoromethane. This destruction process is equivalent to an annual reduction of over 250 million tons of CO2e in greenhouse gas emissions. Professor Hu Jianxin of Peking University's School of Environmental Sciences and Engineering noted that China's use of low Global Warming Potential (GWP) refrigerants has led to a significant gap between its control targets and actual HFC usage, amounting to nearly 1.2 billion tons of CO2e. He further contextualized this achievement by comparing it to the Three Gorges Dam's annual CO2e reduction from coal power generation, suggesting China's three-year reduction is equivalent to the dam's 12 years of emissions reduction.
Key points
- China has exceeded its phased compliance targets for the Montreal Protocol.
- The country has eliminated over 720,000 tons of ozone-depleting substances.
- China has significantly reduced hydrofluorocarbon (HFC) production and consumption, surpassing national targets.
- Annual destruction of trifluoromethane contributes over 250 million tons of CO2e reduction.
- These efforts significantly contribute to global environmental governance and climate change mitigation.
China's success in exceeding its ozone protection targets suggests a strong capacity for implementing and enforcing environmental policies. This overachievement could inspire and enable other nations to pursue more ambitious climate goals, accelerating global efforts to combat climate change and protect the planet's atmosphere.
While China has met its targets, the continued use and production of HFCs, even at reduced levels, still contribute to greenhouse gas emissions. Future challenges may arise in ensuring complete phase-out and managing the transition to even lower-GWP alternatives across all sectors.
