Extreme Heat is Costing India Billions


 
From 1950 to 2022 there has been over a 250% increase in the frequency of days of extreme heat in India. The International Institute for Environment and Development defines temperatures at 35c or above as extreme. At this point workers operating at moderate intensity lose half of their labour capacity according to the International Labour Organisation (ILO).

Extreme Heat is Costing India Billions




A report produced by Lancet estimated that 181 billion potential working hours were lost in India due to heat exposure in 2023. This was a 50% increase from the 1900-1999 annual average. Consequently, there was a potential income loss of $141 billion that year due to labour capacity reduction. With the frequency of days of extreme heat continuing to rise, this heat cost burden will continue to grow.
