Recent studies have shown that the increasing temperatures resulting from climate change pose a direct threat to the lives and health of billions of workers globally, potentially leading to a global health and economic catastrophe. A recent report revealed that over 70% of the global workforce, equivalent to 2.4 billion workers, face severe health risks due to extreme heat, particularly in open areas and poorly equipped factories. The UN Secretary-General has warned of this escalating crisis, calling for urgent international cooperation to mitigate its impacts.

Africa tops the list of the most affected regions, with 93% of its workers facing extreme heat risks, followed by the Arabian Peninsula at 83%. Europe and Central Asia have also seen a sharp increase in these risks, rising by 17% since 2020. Heat stress poses a significant threat to workers’ health, leading to an increased risk of chronic diseases such as cardiovascular, respiratory, and kidney diseases, while also reducing productivity and negatively impacting the global economy. Additionally, there is an increased mortality rate, particularly among the elderly.

Studies predict that climate change will lead to a significant rise in heat-related deaths in the coming years, especially in the hottest regions. There is also an expected increase in deaths caused by droughts, floods, and wildfires. To mitigate the effects of extreme heat on workers, studies recommend a range of measures, including providing safe working environments, such as access to drinking water and shaded rest areas, updating systems and regulations, and fostering international cooperation to share expertise and knowledge in combating climate change.
