On August 24th, the General Office of the Ministry of Ecology and Environment issuedLetter on Soliciting Opinions on the Setting and Allocation Plan of Total Quotas for Ozone Depleting Substances and Hydrofluorocarbons in 2027(Environmental Office Letter [2026] No. 278), the "2027 Total Quota Setting and Distribution Plan for Ozone Depleting Substances (Draft for Comments)" and the "2027 Total Quota Setting and Distribution Plan for Hydrofluorocarbons (Draft for Comments)" are simultaneously open for public comments.
Clear quantitative indicators release strict control signals:The total production quota for controlled use of HCFCs in 2027 is 151416 tons, and the baseline for controlled use production of HFCs is 1.853 billion tons of carbon dioxide equivalentTotal control, refined allocation, and closed-loop accountability throughout the entire lifecycle -“Quota era”The outline is becoming clearer and clearer.
First understand:What are ODS and fluorinated greenhouse gases?
ODS， The full name is Ozone Depleting Substances. It mainly includes six categories of halogenated hydrocarbons:Fluorochlorocarbons (CFCs), Hydrochlorofluorocarbons (HCFCs), Halons, Carbon Tetrachloride (CCl4), Methyl Chloroform (CH3CCl3), and Methyl Bromide (CH3Br)They are widely used in fields such as refrigeration, cleaning, and foaming, but they can release halogen atoms in the stratosphere and catalyze ozone photolysis reactions - the "culprit" of the Antarctic ozone hole, causing excessive ultraviolet radiation to directly hit the Earth's surface.
Fluorinated greenhouse gases refer to hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3) controlled by the Kyoto Protocol. Its global warming potential is extremely high, making it an invisible driving force behind climate change.
As a compliant country of the Montreal Protocol and the Kigali Amendment, China's monitoring of ODS and fluorinated greenhouse gases is no longer an "option", but ratherCompliance, regulation, and dual carbon targetsThe triple rigid demand is to implement phase out and reduction commitments with data, evaluate the effectiveness of ozone layer remediation with data, and support high GWP substance control and industrial green transformation with data.
Continuous policy escalation:Monitoring has changed from 'suggestion' to 'hard requirement'
Looking back at the policy context of the past three years, the signals are becoming increasingly clear:
In 2024, if a unit that produces or uses a large amount of ODS and generates a large amount of it, fails to install automatic monitoring equipment and connect it to the internet as required, or fails to ensure the authenticity and accuracy of monitoring data, it shall be ordered to make corrections and fined not less than 20000 yuan but not more than 200000 yuan; Those who refuse to make corrections shall be ordered to suspend production or business for rectification.
By 2025, gradually improve the atmospheric monitoring network for controlled substances, establish a big data system for compliance monitoring, and promote emissions from production units, key user units, and surrounding areas
environmental monitoringSupervision and law enforcement have been fully implemented in key areas.
In 2026, provinces such as Hebei, Jiangsu, Zhejiang, Guangdong, Henan, Liaoning, Jiangxi, Hubei, Yunnan, Qinghai, as well as key fluorine chemical industrial parks, will construct ODS and HFC monitoring stations as needed; Promote relevant provinces to equip ODS and HFC navigation monitoring equipment.
From national to local, from fixed stations to mobile vehicles, 'whether to install monitoring' is becoming 'mandatory and accurate'.

CF4All six categories of ODS controlled by the Montreal Protocol and all categories controlled by the Kyoto Protocol, including
Four major categories of fluorinated greenhouse gasesIt can be widely used for online monitoring of ODS and fluorinated greenhouse gases in atmospheric background stations, urban monitoring stations, industrial parks, as well as automated offline analysis of ODS and fluorinated greenhouse gases in laboratory air samples.
In addition, Xianhe is equipped with a portable ozone depleting substance detector that can quickly detect substances that deplete the ozone layerCFC-11、HCFC-141b、HFC-245fa、HFC-365mfc、 Cyclopentane, methyl formate, heptafluoropropaneThe substance is used for screening enterprises that illegally produce, use, and sell ODS in ecological environment administrative law enforcement.
From international compliance and regulatory enforcement to ozone layer remediation and dual carbon implementation, monitoring of ODS and fluorinated greenhouse gases is an essential core support for ecological governance. Xianhe Environmental Protection breaks through the technical barriers of trace gas monitoring, builds a scientific, automated, and intelligent ecological monitoring system with monitoring capabilities, safeguards the ecological red line with hard core scientific and technological innovation strength, empowers atmospheric governance, greenhouse gas traceability control, and global ecological compliance, and helps promote high-quality and sustainable development of the ecological environment.
