The Environmental Defense Fund is improving urban air quality management with Air Insights, a suite of open-source tools designed to help cities translate pollution data into actionable public health interventions.
Cities globally collect unprecedented volumes of air quality data, yet technical and capacity gaps frequently prevent municipal authorities from converting these metrics into effective clean air policies, according to the Environmental Defense Fund. For over a decade, scientists have partnered with urban centers to pioneer analytical methods and track pollution hotspots.
Air Insights combines these capabilities into a single, cohesive package to guide city teams, community leaders, and researchers. According to the Environmental Defense Fund, interested cities can contact the team via an online form to become an Air Insights city, share a good use case, or reach out directly at edfair@edf.org.
Written in Python and hosted on GitHub, the open-source code package integrates directly with existing municipal air management systems through user-friendly example notebooks. The platform adapts to individual city requirements by offering four distinct core capabilities.
Municipal teams utilize the toolkit to answer critical questions regarding local pollution dynamics. The system identifies pollution hotspots, traces contributing sources, evaluates the efficacy of existing environmental policies, monitors long-term pollution trends, and assesses the reliability of local datasets for regulatory action.
The package grants access to specialized instruments such as the Air Tracker tool, which traces the trajectories of multiple pollution spikes across time to isolate recurring patterns and potential emission sources. Heat map visualizations, demonstrated in deployments across Rio de Janeiro, illustrate how municipal operators visualize complex pollutant pathways.
The Environmental Defense Action Fund PAC separately filed its fundraising and expenditure reports covering the period from Oct 1, 2026 -Oct 14, 2026, according to the Environmental Defense Action Fund PAC reporting data which notes that the data may contain refunds given to the committee, that names are hidden for individual donations below $250,000, and that the data doesn’t include operating expenditures and transfers to other committees.
Cities interested in integrating the open-source analytics package can access implementation resources through the developer network.
