Clean Routing surfaces the safest, healthiest routes between any two points, ranked by pollen and pollution exposure.
According to the Asthma and Allergy Foundation of America
According to research published in PNAS by Anderegg and colleagues
According to the World Allergy Organization
Clean Routing ranks every available path between two points by environmental exposure, returning the cleanest option with the data behind it.
Over 30 pollen allergens, including birch, oak, and ragweed, are factored into every route and categorized across trees, grasses, and weeds.
PM2.5, PM10, NO2, SO2, CO, and ozone are tracked simultaneously and factored into every route recommendation.
Forecasted routes show the best paths with the least pollen and pollution exposure ahead of any journey.
Every route comes with detailed concentration and risk levels along the path, perfect for personalization.
Clean Routing gives you complete control over how the experience looks, feels, and functions, across web, mobile, smartwatch, and in-vehicle environments.
Sanofi wanted to give allergy sufferers the confidence to go outside and breathe safely, and doing that meant building something that had never existed before. Working with the Allegra team, Clean Routing powered a navigation experience that ranks routes by live pollen and air quality exposure across 12 pollen allergens and 6 air pollutants.
The pilot launched at UN Climate Week NYC in September 2023, and six months later, Allegra Airways expanded to a pan-US release at SXSW, covering 9 million square kilometres of the United States.
Within weeks of launch, Allegra Airways generated 237 million impressions, created over 325,000 clean routes, drove $3M in sales, and won a Silver Lion at Cannes Lions 2024 in the Health and Wellness category.
