Abstract

Inequalities in exposure to PM2.5 reflect disproportionate distribution of health risks across populations. This study assesses global PM2.5 exposure inequalities and associated trends since 2000. Results show that 118 countries reduced intra-country inequalities, but global disparities intensified due to widening gaps between developing and developed regions. By identifying pathways and country-specific contributions to global inequalities, we show that environmental policy shifts in major economies can rapidly reshape global inequality patterns.

期刊介绍: npj Climate and Atmospheric Science is an open-access journal encompassing the relevant physical, chemical, and biological aspects of atmospheric and climate science. The journal places particular emphasis on regional studies that unveil new insights into specific localities, including examinations of local atmospheric composition, such as aerosols. The range of topics covered by the journal includes climate dynamics, climate variability, weather and climate prediction, climate change, ocean dynamics, weather extremes, air pollution, atmospheric chemistry (including aerosols), the hydrological cycle, and atmosphere–ocean and atmosphere–land interactions. The journal welcomes studies employing a diverse array of methods, including numerical and statistical modeling, the development and application of in situ observational techniques, remote sensing, and the development or evaluation of new reanalyses.
