Extreme heat could make outdoor work increasingly unsafe across Indian cities, leading to significant job-equivalent labour losses and economic costs, according to a World Bank report. New Delhi, Kolkata, Mumbai and Chennai are projected to lose hundreds of thousands of full-time jobs by 2050 as working hours become unsafe.

The losses rise sharply on days when temperatures exceed 37°C

The World Bank warns that extreme heat threatens South Asia's jobs and economic growth, urging urgent action for resilience.
