Global death rates caused by household air pollution 2021, by region

Global death rates linked to household air pollution from solid fuels have more than halved between 1990 and 2021, to roughly 39 per 100,000 inhabitants. The highest global death rates from household air pollution in 2021 were observed in South Asia and Sub-Saharan Africa, at 77 and 65 deaths per 100,000 inhabitants, respectively. In comparison, the average death rates in high-income countries were just 0.06 per 100,000 inhabitants. One of the main factors for this stark difference is that many people lack access to clean cooking and heating fuels in developing countries. Nevertheless, regional death rates linked to household air pollution have improved markedly in over the past three decades.

自1990年至2021年，与固体燃料引起的家庭室内空气污染相关的全球死亡率已减半，降至每10万人中约39例。2021年，南亚和撒哈拉以南非洲的家庭空气污染导致的死亡率最高，分别为每10万人中77例和65例。相比之下，高收入国家的平均死亡率仅为每10万人中0.06例。造成这种显著差异的主要因素之一是许多发展中国家的人们缺乏清洁烹饪和取暖燃料。尽管如此，在过去三十年中，与家庭空气污染相关的区域性死亡率已经显著改善。
