Rising heat in the workplace implies severe effects for Least Developed Countries, Small Island Developing States (SIDS) and emerging economies with high concentrations of outdoor labour and industrial and service sector workers operating in ineffectively climate controlled conditions. Its consequences imply effects for a majority of the Sustainable Development Goals (SDGs), including poverty (SDG1) and hunger (2), health (3), education (4), gender (5) and income inequalities (10), good jobs and growth (8), and sustainable cities and communities (11).
