We have just launched the first large real-time global crowd-sourced carbon dioxide map. The data comes from more than 500 open source AirGradient air quality monitors that are run by engaged citizens around the world. This marks a significant milestone in environmental monitoring, especially in the context of ever-increasing CO2 levels, which we recently saw increase by a record-breaking 5ppm compared to last year.
