The cost of inaction: Quantifying the impact of climate change on health in low- and middle-income countries

This report aims to address the existing knowledge gap and provide a deeper understanding of the interconnection between climate and health, in terms of the risks to human health and the economic burden of these risks. Specifically, it provides a quantitative assessment of the potential impacts of climate change based on the number of cases and the number of deaths resulting from selected vector- and water-borne diseases, stunting, and extreme heat.

This report also provides an assessment of the economic cost of climate change on health (in terms of both morbidity and mortality). The analysis covers 69 low-income and middle-income countries with national populations exceeding 10 million people in the base year 2020. These 69 countries comprise 96 percent of the total population of all low- and middle-income countries (LMICs).
