Ensuring safety and health at work in a changing climate

A “staggering” number of workers, amounting to more than 70 per cent of the global workforce, are likely to be exposed to climate-change-related health hazards, and existing occupational safety and health (OSH) protections are struggling to keep up with the resulting risks, according to a new report by the International Labour Organization (ILO). The report, Ensuring safety and health at work in a changing climate, says that climate change is already having a serious impact on the safety and health of workers in all regions of the world. The ILO estimates that more than 2.4 billion workers (out of a global workforce of 3.4 billion) are likely to be exposed to excessive heat at some point during their work, according to the most recent figures available (2020). When calculated as a share of the global workforce, the proportion has increased from 65.5 per cent to 70.9 per cent since 2000.
