- India gains global textile orders, but extreme heat is eroding worker productivity, exposing a hidden thermodynamic crisis in labour-intensive manufacturing.
Reasons for the Crisis
- Climate Warming: India is warming faster than the global average, with rising heatwaves intensifying heat stress in textile hubs (IPCC AR6).
- Design Mismatch: Factories built for cooler climates lack ventilation/cooling, with indoor temperatures often crossing 35–40°C.
- Informal Labour: Over 80–90% workers are informal, lacking breaks & legal thermal safety protections.
- Supply Pressure: Global brands enforce tight deadlines/penalties, forcing production despite unsafe heat conditions.
Current Facts & Data
- Employment Base: The textile sector employs 45 mn, a major share of the manufacturing workforce.
- Global Share: India produces ~39% of global cotton, making it central to global textile supply chains.
- Labour Loss: Heat stress caused 259 bn labour-hour losses (2001–20), costing $600 billion annually.
- Recent Spike: In 2024, heat stress alone led to an estimated 247 billion labour-hour losses.
- Output Decline: Productivity drops ~2% per °C rise, reaching ~4% decline during extreme heat days.
- Thermal Stress: Factory temperatures in clusters exceed 35–40°C, far above the safe threshold of 30°C.

Heat-Induced Productivity Crisis
- Labour Loss: Extreme heat leads to loss of ~259 billion work hours annually, causing massive economic losses and reduced national productivity.
- Factory Slowdown: Rising temperatures force factories to cut working hours and reduce output by up to 50%, affecting industrial efficiency.
- Health Stress: Heat levels above 35°C cause fatigue, dehydration, and heatstroke, significantly lowering workers’ physical capacity and safety.
- Supply Pressure: Strict global deadlines push factories to risk worker health or face financial penalties, burdening vulnerable labourers.
- Future Risk: By 2030, India may lose 5.8% working hours (~34 million jobs), threatening jobs, incomes, and supply chains.
Heat Stress Challenges
- Policy Gap: Heat stress is poorly recognised in labour frameworks, despite India losing ~259 billion work hours annually due to extreme heat.
- Labour Protection: Labour codes lack clear heat safety norms, even as factory temperatures often exceed 35–40°C against the safe 30°C limit.
- Infra Deficit: Costly cooling systems and retrofits limit MSMEs, with many units unable to invest despite rising heat disruptions.
- Buyer Pressure: Global brands impose strict deadlines and penalties, as seen during COVID-19, when $2.8 billion orders were cancelled, burdening workers.
- Data Deficit: Limited monitoring of indoor heat and worker health persists, even though studies show productivity drops ~2% per 1°C rise.
Way Forward
- Policy Integration: Recognise heat stress as a supply chain risk and integrate it into policies like the National Action Plan on Climate Change (NAPCC) and Heat Action Plans.
- Heat Action Plans: Mandate workplace heat protocols such as cooling breaks and health checks, as seen in the Ahmedabad Heat Action Plan, reducing heat mortality.
- Climate Finance: Enable green financing via concessional credit and ESG norms. E.g., schemes such as SIDBI’s support for MSMEs can fund cooling technology and water systems.
- Labour Safety: Strengthen occupational safety laws with provisions like drinking water, shaded rest areas, and guidelines under the Occupational Safety, Health and Working Conditions Code, 2020.
- Tech Innovation: Promote R&D grants for cooling wearables, heat-tolerant cotton, and energy-efficient manufacturing processes.
“Nature cannot be fooled.” India’s textile growth cannot rely on ignoring labour’s thermal limits; a shift to climate-smart, worker-centric and resilient supply chains is essential for sustaining livelihoods and global competitiveness.
