Who contributed?

Health Effects Institute: HEI is an independent global health and air research institute, a leader of the air pollution analysis within the Global Burden of Disease (GBD) project, and the producer most recently of the GBD–Major Air Pollution Sources (GBD MAPS) report on China and upcoming India report. HEI is the primary developer of the State of Global Air report, host and manager for this website, coordinator of input from all other members of the team, and facilitator of contact with media partners.

The Institute for Health Metrics and Evaluation:  IHME is an independent population health research center at UW Medicine, part of the University of Washington, which provides rigorous and comparable measurement of the world's most important health problems and evaluates the strategies used to address them. Among its work, IHME publishes the annual Global Burden of Diseases, Injuries, and Risk Factors, a systematic, scientific effort to quantify the magnitude of health loss from all major diseases, injuries, and risk factors by age, sex, and population. A key collaborator on the State of Global Air initiative, IHME provides the underlying air pollution and health data and other critical support for this project.
