Under the dual pressure of global carbon neutrality goals and energy consumption controls in the cold chain sector, carbon accounting for cold storage is expanding from "equipment" to "envelope systems." Traditional metal duct systems not only consume high operational energy but also carry a shocking amount of embodied carbon throughout their lifecycle. Producing one ton of galvanized steel emits approximately 2.1 tons of CO₂, while the external rubber insulation is a highly polluting byproduct. Coupled with on-site welding and insulation installation emissions, the ventilation system for a 10,000-ton cold storage facility can generate dozens of tons of embodied carbon. Fiber Fabric Ducts​ are emerging as the "Green Ledger" of cold chain construction, utilizing their low-carbon DNA and dry-installation characteristics to inject sustainable competitiveness into cold storage through a full lifecycle decarbonization logic.

The green pain points of cold chain facilities center on three areas: "heavy materials, dirty construction, and difficult recycling." Metal ducts undergo highly energy-intensive processes from ore smelting to finished product—mining, sintering, and rolling—keeping carbon density extremely high. During on-site installation, welding fumes and volatile organic compounds (VOCs) from insulation adhesives directly pollute the internal environment, contradicting the goals of a green cold storage facility. Fabric ducts reverse this trend at the source: the base material utilizes recycled PET bottle flakes for spinning, with carbon emissions per ton of fiber being only 1/8th of that of metal materials. The factory prefabrication + on-site rail assembly​ dry-construction model achieves "zero welding, zero glue, and zero dust," making installation-phase emissions virtually negligible.

This green value is particularly prominent in three cold chain scenarios:

• Zero-Carbon Cold Storage Demonstration Projects:​ A large cold chain park included fabric ducts in its building material carbon footprint inventory, reducing the embodied carbon of the ventilation system by approximately 38 tons in a single project, which helped the park achieve LEED Platinum certification.

• Green Retrofitting of Old Facilities:​ Driven by the Green Cold Storage Evaluation Standards, replacing old ducts with fabric systems requires no hot work or operational shutdowns, avoiding additional carbon emissions during renovation. Furthermore, the old ducts can be recycled and remanufactured, creating a closed-loop system.

• Cross-Border Cold Chain Compliance:​ Facing the EU's Carbon Border Adjustment Mechanism (CBAM), export-oriented cold chain enterprises adopting low-carbon ventilation materials can effectively reduce product carbon footprints and enhance international competitiveness.

It is important to note that cold chain-specific fabric ducts must pass the Green Building Material Product Certification (3-Star Rating)​ to ensure full-chain environmental friendliness from raw material to disposal. As carbon border taxes and ESG disclosures become mandatory for the cold chain industry, fiber fabric ducts are evolving from mere ventilation equipment into an "invisible加分项 (value-add)" for a cold storage's green competitiveness—writing the sustainable future of cold chain infrastructure with quantifiable decarbonization data.
