Open Air Quality Data: The Global Landscape

Open Air Quality Data: The Global Landscape is the only global assessment of whether and how national governments are producing and sharing air quality data with the public.

OpenAQ—an NGO that hosts the world’s largest opensource, open-access database of real-time and historical outdoor air quality measurements—analyzed countries across the world to determine which have government-level air quality monitoring programs and whether and how those governments are opening their monitoring data to the public

This report finds that only a small subset of countries are providing fully transparent air quality data. Many countries don’t fully open their data, and many of the most populated, polluted countries have no national air quality monitoring at all.
