Adverse effects of occupational heat stress in the context of the changing climate on working populations are subtle but considerably harmful. However, social dimensions and impacts of climate change-related occupational heat concerns on workers' safety and health, productivity and well-being are often overlooked or relegated as minor issues in social impact analyses of occupational heat exposure due to climate change. This paper offers a conceptual framework based on an appraisal and synthesis of the literature on social impacts of climate change-related occupational heat exposure on workers' safety and health, productivity and social welfare and the quest to localise and achieve sustainable development goals. A sustained global, national, institutional and individual collaborative involvement and financial support for research, improved adaptation and social protection strategies, predominantly in the developing world, where a large number of people work outdoors, can reduce heat exposure and boost the resilience and adaptive capacity of workers to facilitate efforts to achieve sustainable development goals.
