Climate change isn’t just about rising seas or melting glaciers anymore – it’s affecting how we work and live every single day. The World Health Organization (WHO) has warned that for every 1°C rise in global temperature, global warming slashes worker productivity by 2–3%. That means as the world gets hotter, workers everywhere, from farmers to office staff, are struggling to keep up.
Why Does Heat Make it Harder to Work?
Anyone who has tried to work on a scorching afternoon knows the toll it takes. When the body overheats, it works overtime to stay cool, draining energy, reducing focus, and causing fatigue. Outdoor workers like farmers, delivery staff, and construction crews are on the frontline of this struggle. But indoor workers aren’t spared either – hot, poorly ventilated offices quickly sap concentration.

Which Industries Are Most Affected?
Some sectors are taking the hit harder than others. Agriculture is especially vulnerable, with farmers forced to slow down under extreme heat. Construction projects often face delays because workers need more breaks. Manufacturing plants, where machinery generates additional heat, also see declines. Even transport and logistics feel the pressure when schedules get disrupted due to temperature spikes.

What Does This Mean for Economies?
When global warming slashes worker productivity by 2–3%, it’s not just about tired workers; it hits entire economies. Lower productivity leads to reduced output, service delays, and more spending on healthcare as heat-related illnesses rise. Developing nations, with large labor-intensive sectors, are especially vulnerable.
Wealthier nations, on the other hand, may find themselves pouring money into air conditioning, altered work hours, and new safety measures. The International Labour Organization (ILO) already estimates that climate-linked productivity losses are costing billions globally.
Economic Impacts of Heat-Related Worker Productivity Loss (2023–2024)
Category | Loss or Impact | Source / Context |
|---|---|---|
Global Income Loss (2023) | ≈ $835 billion | Due to heat exposure and lost working hours—record high globally. |
Working Hours Lost (2023) | 512 billion hours | Equivalent to massive economic output loss. |
GDP Loss – Low-HDI Countries | ~8% per worker (average) | Low-HDI countries heavily impacted in 2023. |
GDP Loss – High-HDI Countries | ~1% per worker (average) | Less affected compared to low-HDI nations. |
Potential OSH Savings | Up to $361 billion annually | Estimated savings from implementing occupational safety and health measures. |
Economic Costs Forecast | $100 billion (2020) growing toward $500 billion by 2050 | Illustrates escalation of heat-related productivity losses. |

Can Anything Be Done to Protect Workers?
The solution, experts say, needs to happen on two levels:
- On the global stage, cutting emissions and slowing warming is critical. Events like COP28 highlight this urgency.
- At the workplace level, though, changes can happen right now: shaded rest areas, plenty of drinking water, shorter or flexible shifts, and better ventilation. Companies are even exploring climate-friendly uniforms and cooling tech to shield workers from heat.
If global temperatures keep rising, work may need to adapt, such as shorter shifts, night work, or more automation, just to maintain productivity. The WHO’s warning is clear: addressing climate change isn’t only about protecting the planet – it’s about safeguarding workers and their well-being. Smarter workplace practices, innovative solutions, and sustainability measures are essential today to ensure people and economies can thrive in a warming world.
