Clean air is a human right and PHAN exists to protect it. We’re building a trusted global organization that fosters collaboration across public health, technology, and community sectors to prevent disease, reduce exposure to airborne threats, and support those already impacted by conditions like Long COVID. From pathogens to pollution and climate-driven hazards, we create accessible, repurposable tools that bridge research and real life, restoring public trust and helping people everywhere breathe safer and live healthier.
Join the Health Effects Institute’s State of Global Air initiative for an informative webinar on the State of Global Air 2025 report (releasing on October 23, 2025). The State of Global Air report and interactive website bring into one place a comprehensive analysis of the levels and trends in air quality and health for every country in the world. Please join us to discuss the key messages from the new State of Global Air 2025 report and opportunities for using the data for action on air pollution.
The goal of this webinar is to provide an overview of key messages from the State of Global Air 2025 report and discuss potential uses for the data.
