Turning air quality data into action
We turn air quality data into answers people can act on. How does air pollution affect me? Will this intervention work? What would make the biggest difference for my community?

PCAP
LiveEstimates personal PM2.5 and NO2 exposure based on where you live, work, and travel — then shows what would make the biggest difference.
→RHEA
Research PreviewEvaluates whether air quality interventions actually work, using rigorous statistical methods that stand up to scrutiny.
→Aeolus
Open SourceOpen-source Python library for downloading, standardising, and analysing air quality data from monitoring networks worldwide.
→RHEA Case Study
Edinburgh's LEZ cut evening rush NO2 by 6.6 µg/m³
RHEA found a clear drop in NO<sub>2</sub> during the evening rush — concentrated between 4pm and 6pm, exactly when you'd expect a vehicle restriction to bite. The effect is statistically significant (p = 0.006).
