  1. $340,729 spent. Air Quality Data Platform: To meet the needs of air quality researchers, community advocates, journalists and other air quality changemakers, OpenAQ provides the worlds largest open-access, open-source air quality data platform. In 2025, we aggregated new data from ~3,400 locations, including ~1,400 locations in low- and middle-income countries, reaching a total of more than 22,000 locations in 141 countries. We saw a 187% increase in registered users, totaling more than 19,000. Active API use leaped by 550% to 2,700 per quarter and active OpenAQ Explorer use increased by 34% to 250 per day. ~175 publications cited their use of OpenAQ, an average of over 14 per month.
  2. $198,314 spent. Community Engagement: Through webinars, trainings, speaking engagements, conference attendance, one-on-one meetings, impact stories and more, we introduced potential new users to the OpenAQ data platform and supported existing data practitioners. Through our Clean Air Community Ambassador program, we provided professional leadership training to 10 emerging air quality leaders from the world's most polluted regions. We connected air quality data producers and users across sectors and geographies to support an international learning environment. These and other outreach activities have resulted in greater use of the platform for air quality analysis and clean air advocacy.
