What's new in 2018?

New features in State of Global Air 2018:

Household Air Pollution

When wood, dung, peat, and other solid biomass are burned as fuels for cooking and heating, a combination of incomplete combustion and lack of ventilation can lead to high concentrations of particulate matter and other pollutants in the home.

The 2018 State of Global Air presents GBD data on the proportion of the population in each country around the world that relies on solid fuels and the resulting burden that such exposures to household air pollution have on human health.

Read more in the Report and on the Air Quality and Health Impact pages. Now you can also explore the data for household air pollution, in addition to fine particles and ozone. 

"Total" Air Pollution

Given that air pollution is a mixture of particulates and gases, no single measure of exposure to total air pollution exists. However, the State of Global Air presents the estimate of the total impact of air pollution as it is represented in the GBD project today (fine particulate matter, ozone, and household air pollution combined).

We’ve added GBD data on the combined disease burden from exposures to fine particles, ozone, and household air pollution for every country in the world. Read more in the Report, and on the Air Quality and Health Impact pages. Now you can also explore the data for total air pollution.

Major Sources

A new page What are the Major Sources of Outdoor Air Pollution? provides information on what sources contribute to population exposures to air pollution, with a focus on China and India. 
 

Future updates

Future versions of the State of Global Air may include additional pollutants, data on sensitive populations, and additional health outcomes and health metrics. Read more in What’s Next.
