🔥 Extreme heat is quietly reshaping the global economy.

Every year, the equivalent of 300+ million full-time jobs are lost — not to layoffs, but because work has simply become too hot to do.

In 2024 alone:
• 639 billion work hours lost worldwide
• Shifts cut short and projects delayed
• Power cuts and transport disruptions
• Workers falling ill and incomes disappearing

Outdoor workers are hit first — and hardest. Construction workers, farmers, street vendors and delivery drivers face rising risks as temperatures climb.

🌍 2.3 billion workers — one in four people worldwide — are already affected.

Extreme heat is no longer just a climate issue. It is a growing economic crisis that demands coordinated action.

UNDRR is working with partners to strengthen heat-risk governance and protect people, livelihoods and economies.
