Global fashion brands face new supply chain risks as extreme heat disrupts production in Asia, according to a Bloomberg analysis published May 12. The report highlighted how record temperatures in India, Bangladesh, and Vietnam — which account for approximately 70% of global apparel exports — are causing factory absenteeism, production delays, and cost increases, directly impacting corporate earnings. This marks a shift from treating climate change as an ESG issue to recognizing it as an immediate operational and financial risk for the $1.7 trillion global apparel industry employing over 90 million workers.
Heat Exposes Vulnerabilities in Asian Garment Factory Operations
Garment factories are particularly vulnerable to extreme heat due to their operational structure. Hundreds of workers operate sewing machines and pressing equipment in densely packed spaces, and many facilities lack adequate insulation and ventilation systems. As heat waves intensify, absenteeism increases and work efficiency declines, leading to production delays and missed delivery deadlines.
Most global fashion brands — including H&M, Zara, and Lululemon — do not operate their own factories. Instead, they outsource production to OEM and ODM partners in Asia. This structure means production disruptions in India, Bangladesh, or Vietnam directly translate into supply shortages, delivery delays, and rising costs for brands.
Cornell University's Global Labor Institute projected that continued heat waves and flooding in Bangladesh, Cambodia, Pakistan, and Vietnam could reduce apparel exports by approximately $65 billion by 2030. This scale of disruption would directly affect production schedules and product availability for global brands. NYU Stern School of Management noted last month that because approximately 70% of global apparel exports originate in Asia, heat risk extends beyond individual countries to threaten the entire supply chain.
Fast Retailing Adopts Long-Term Supplier Contracts to Support Facility Upgrades
Fast Retailing, which operates Uniqlo, exemplifies a strategic response to heat-related production risks. The company is known for signing multi-year contracts with suppliers rather than switching production partners annually to reduce unit costs. This long-term commitment allows factories to invest in equipment and working environment improvements, including heat-adaptation measures.
Fast Retailing uses long-term supply agreements to enable partner factories to invest in cooling systems, eco-friendly facilities, and improved working conditions. The company stated that long-term contracts provide suppliers with the stability needed to invest in facility improvements, greenhouse gas reduction, and enhanced working environments.
Epic Group Opens Heat-Resilient Factory in India
Epic Group, a Hong Kong-based garment manufacturer producing for Uniqlo and other global brands, opened a new production facility in Odisha, India in April. The facility was designed specifically to address extreme heat conditions. Spanning approximately 160,000 square meters and accommodating up to 10,000 workers, the factory maintains an internal temperature of approximately 28°C even when external temperatures exceed 34°C.
The facility incorporates double-entry doors designed to prevent external heat infiltration, large-scale air circulation systems, thermally insulated roofing, and industrial heat pumps to simultaneously improve cooling efficiency and reduce energy consumption. Initial production volume is primarily dedicated to Uniqlo products.
Vidura Lallapanawe, Vice President of Epic Group, told Bloomberg that traditional industrial buildings were designed to protect machinery — the most valuable asset — but now must be redesigned to protect people. He noted that the apparel industry has underestimated heat risk because changes occur gradually, comparing the situation to a frog in slowly boiling water that fails to recognize danger.
Factory workers report tangible differences. Mamata Sahani, who works at the new facility, stated that in her previous factory, the tin roof became so hot in summer that it felt like working inside an oven. She said she can now work without sweating, allowing much better concentration on tasks. Bloomberg assessed that heat adaptation extends beyond welfare considerations to directly affect productivity, quality, and delivery competitiveness.
AAFA Issues Guidelines on Shared Heat-Adaptation Costs
The broader industry has begun responding. The American Apparel & Footers Association (AAFA), whose membership includes approximately 1,100 companies such as Ralph Lauren and Levi's, issued guidelines in April advising member companies not to shift heat-adaptation costs solely onto suppliers but to share the financial burden.
Investor evaluation criteria are also shifting. While brand competitiveness, revenue growth, and cost ratios were previously the primary assessment factors, the ability to operate production bases stably is emerging as a critical investment criterion. Long-term supplier contracts, working environment improvements, and production base diversification now influence corporate earnings and supply capacity.
Corporate response strategies vary. Global fashion companies with high Asia production exposure face potentially increased facility investment requirements and cost burdens related to heat adaptation.
