Extreme Heat Costs Bangladesh $1.8 Billion and 465,000 Jobs Annually, World Bank Reports

Dhaka, July 30, 2026 — Extreme heat is costing Bangladesh an estimated $1.3 to $1.8 billion annually, equivalent to 0.3-0.4 percent of its Gross Domestic Product (GDP), according to a new World Bank report that paints a stark picture of the economic impact of rising temperatures on the country's workforce and export industries. 🌡️ The report, titled "A Livable Future: Protecting Jobs and Growth from Extreme Heat in South Asia's Cities", was released on July 29, 2026, and highlights the growing threat that extreme heat poses to Bangladesh's economy. 📊

🏭 The impact is most acute in the capital, Dhaka, where heat renders 3 percent of annual working hours unworkable, effectively erasing the equivalent of 465,000 full-time jobs every year. The losses rise sharply on days when temperatures exceed 37°C, according to the World Bank analysis. 📈

🌡️ Key Findings of the World Bank Report

📊 The report reveals several alarming statistics about the impact of extreme heat on Bangladesh's economy:

• 💰 Annual GDP loss — $1.3-1.8 billion (0.3-0.4% of GDP) in 2024
• 👥 Jobs lost in Dhaka — 465,000 full-time equivalent jobs annually
• ⏰ Working hours lost — 3% of annual working hours in Dhaka
• 🌡️ Critical threshold — losses rise sharply above 37°C
• 📈 Future projection — losses expected to more than double by 2080
• 🏙️ Dhaka 2080 projection — 7.4% of productive hours lost

🌐 At a regional level, the report found that extreme heat is costing South Asia nearly the equivalent of 31 million full-time jobs every year and is on track to reduce the region's economy by nearly 7 percent by 2050. As South Asia prepares to add 280 million working-age people by 2050, rising temperatures represent one of the greatest threats to jobs, productivity, and long-term economic growth in the region. 🌏

👕 Threat to Bangladesh's RMG Sector

🏭 The World Bank report specifically highlights the threat to Bangladesh's readymade garment (RMG) sector, the country's dominant export earner accounting for over 80 percent of merchandise exports. The report cites an analysis by the International Labour Organization (ILO), the International Finance Corporation (IFC), and Cornell University's Global Labor Institute:

"The apparel sectors of Bangladesh, Pakistan, Vietnam, and Cambodia could forgo up to $65.8 billion in export earnings by 2030 if heat stress goes unaddressed."

⚠️ This multi-billion-dollar threat to the RMG sector is particularly concerning for Bangladesh, where millions of workers — predominantly women — work in garment factories that often lack adequate cooling systems. The report also noted that heat stress in Bangladesh's garment factories has been linked to an increased risk of violence and harassment against women workers unable to meet production quotas during extreme heat periods. 👩‍🏭

🌱 Bangladesh's Green Transformation Efforts

✅ Despite the challenges, the World Bank acknowledged Bangladesh's proactive efforts to address heat stress through green transformation initiatives:

• 💰 Green Transformation Fund (GTF) — government-backed fund launched in 2016 to help manufacturers invest in energy- and water-efficient equipment and better working environments; grew from a handful of factories into a sector-wide transition
• 🤝 IFC Partnership for Cleaner Textile — reinforced the GTF through sustainability-linked lending
• 🏅 LEED-certified factories — Bangladesh had over 270 Leadership in Energy and Environmental Design (LEED)-certified apparel factories by the end of 2025, one of the highest concentrations globally

📊 The World Bank emphasized that directed finance can shift the trajectory of heat-related losses. The GTF model demonstrates how targeted financial support can drive sector-wide adoption of sustainable practices, creating cooler and safer working environments while reducing energy consumption. 🌿

📈 Broader South Asia Context

🌏 The World Bank report places Bangladesh's experience within the broader South Asian context, where extreme heat is becoming an increasingly urgent economic challenge:

• 👥 31 million jobs — equivalent full-time jobs lost annually across South Asia
• 📉 7% GDP reduction — projected for South Asia by 2050 if heat trends continue
• 👶 280 million new workers — South Asia will add this many working-age people by 2050
• 🌡️ Rising temperatures — one of the greatest threats to jobs and growth in the region

🌐 The report underscores that the challenge is not unique to Bangladesh — countries across South Asia face similar threats. However, Bangladesh's unique vulnerability stems from its high concentration of labor-intensive manufacturing (particularly RMG) in urban centers like Dhaka, where the urban heat island effect compounds rising global temperatures. 🏙️

🔮 Recommendations and Way Forward

📋 The World Bank report suggests several strategies for addressing the economic impact of extreme heat:

• 💰 Expand directed finance — scale up the Green Transformation Fund model to reach more factories
• 🌡️ Invest in cooling infrastructure — retrofit factories with efficient cooling systems
• 📊 Heat-resilient urban planning — design cities to mitigate urban heat island effects
• 👩‍💼 Worker protection policies — implement heat-stress protocols and adjust working hours during extreme heat
• 🔬 Research and monitoring — track heat-related productivity losses and target interventions
• 🤝 International cooperation — share best practices across South Asian countries

📈 For Bangladesh, the stakes are particularly high. With the RMG sector facing a potential $65.8 billion export earnings loss by 2030, investing in heat resilience is not just an environmental imperative — it is an economic necessity. The World Bank's recognition of Bangladesh's Green Transformation Fund as a successful model provides a roadmap for scaling up climate adaptation efforts in the industrial sector. 🌱

🌐 As global temperatures continue to rise, Bangladesh's experience offers important lessons for other developing countries with large labor-intensive manufacturing sectors. The country's proactive approach — through green financing, LEED certification, and international partnerships — demonstrates that targeted interventions can mitigate the economic impact of extreme heat while supporting sustainable industrial growth. 🎯
