We aggregate and harmonize disparate air quality data from thousands of sources around the world and host the data on our first-of-its-kind free and open-source data platform. We connect users of this data across sectors and geographies to support an international learning environment.&nbsp; Air pollution is the largest environmental threat to human health worldwide and disproportionately burdens people living in low- and middle-income countries and in marginalized communities.

In partnership with the Clean Air Fund, OpenAQ will ensure that the vast amounts of data being generated by the cities participating in Breathe Cities is accessible and actionable to everyone. The project will bring all city data together in one place on an open data portal that has user-friendly tools that will enable anybody to understand and visualize the data in compelling and engaging ways, and will support the platform to be cloned and deployed on any local Breathe City and city government website.
