The State of Global Air (SoGA) is a research and outreach initiative to provide reliable, meaningful information about air quality around the world. This reports provides an overview of air pollution levels and associated health impacts in cities around the world. Since urban areas are often hotspots for poor air quality, city-level data can help to inform targeted efforts to curb urban air pollut...

The Health & Air Quality program area provides policymakers with Earth observations to enhance decision-making about public health, with a special focus on environmental health and infectious diseases. We provide managers and policymakers with Earth observations that inform decisions about air quality standards, public policies and government regulations for economic and human welfare....

With much of the world's population residing in urban areas, an understanding of air pollution exposures at the city level can inform mitigation approaches. Previous studies of global urban air pollution have not considered trends in air pollutant concentrations nor corresponding attributable mortality burdens. Authors aimed to estimate trends in fine particulate matter (PM2·5) concentrations and ...

Ozone and PM2.5 are current risk factors for premature death all over the globe. In coming decades, substantial improvements in public health may be achieved by reducing air pollution. To better understand the potential of emissions policies, studies are needed that assess possible future health impacts under alternative assumptions about future emissions and climate across multiple spatial scales...

The AP-HRA forecasts the expected health effects of policies impacting air quality under various policy, environmental and socioeconomic circumstances. The paper presents the concept of AP-HRA and offers an outline for the conduct of AP-HRA for different scenarios, explaining in broad terms how the health hazards of air emissions and their origins are measured and impacts are quantified....

HAPIT estimates health changes due to interventions designed to lower exposures to household air pollution (HAP) of household members currently using unclean fuels (wood, dung, coal, kerosene, and others). HAPIT currently uses background disease rates and relationships between exposure to PM2.5 and health outcomes described as part of the Institute for Health Metrics and Evaluation's 2013 Global B...

Ce rapport présente un aperçu de l'état de l'air et de ses impacts sur la santé en Afrique. Il rassemble les données du projet Global Burden of Disease et une récente étude qui porte sur l'évaluation à l'échelle mondiale des sources de pollution atmosphérique qui permettent d'évaluer les tendances, les sources et les charges de morbidité associées dans cette région, avec un regard particulier sur ...

Nine out of the world’s 10 cities with the worst air pollution are in South Asia. Concentrations of fine particulate matter (PM 2.5) in some of the region’s most densely populated and poor areas are up to 20 times higher than what WHO considers healthy (5 µg/mᶾ). It causes an estimated 2 million premature deaths in the region each year and incurs significant economic costs. Controlling air polluti...

This article estimated the ambient PM2.5- and ozone-attributable health burden globally from transportation tailpipe emissions globally in 2010 and 2015. The study builds on previous estimates of the health burden from transportation emissions that report transportation air pollution-related mortality estimates for earlier years....

This study analyzes the health and climate impacts associated with projected diesel HDV exhaust emissions in G20 economies under four scenarios: currently adopted policies, expanded adoption of Euro VI-equivalent standards, potential next-generation emission standards, and accelerated fleet renewal programs....
