Rising heat takes toll on Bangladesh’s garment workers

Nature & Climate Perspective

**Compounding regional climate vulnerability and localized urban heat island effects are intensifying thermal stress beyond physiological tipping points in industrial manufacturing zones. **

• Microclimate degradation and loss of urban canopy cover (LULUCF) eliminate natural passive cooling mechanisms, compounding extreme wet-bulb temperatures around dense industrial sectors.
• Accelerated thermal stress impacts regional biomass and soil moisture levels, weakening local ecosystems that act as buffers against monsoon shifts and heat extremes.
• The absence of ecosystem-based adaptation and green infrastructure worsens ambient heat retention, reducing the long-term ecological stability of industrial river basins.

Market & Policy Outlook

**Severe occupational heat exposure threatens global apparel Scope 3 supply chain resilience and exposes gaps against ICVCM Core Carbon Principle safeguards. **

• Physical climate hazards to labor force productivity introduce material transition and operational risks for Western apparel brands under SBTi and CSRD supply chain due diligence mandates.
• Carbon mitigation initiatives in manufacturing facilities must contrast against the ICVCM Core Carbon Principles (CCPs), specifically Principle 7 (Sustainable Development Benefits and Safeguards), requiring projects to explicitly address worker health, safety, and adaptive capacity.
• Rising factory cooling loads drive compliance demand for on-site clean power and I-RECs to mitigate grid carbon intensity, while opening pathways for Article 6.4 bilateral transfer mechanisms (ITMOs) targeting industrial energy efficiency.
