About Estuaire
Estuaire, a data-focused company originating from Paris, is dedicated to mitigating the environmental footprint of the aviation sector. Founded in 2022 by former Airbus employees Augustin de Vulpian and Thomas Pical, the firm provides detailed analytics on aviation's various pollution factors, including CO2, NOx emissions, and the warming effects of contrails. Both founders leverage their extensive aerospace engineering backgrounds from their time at Airbus, where de Vulpian specialized in aircraft performance and operations, and Pical focused on flight physics and aircraft performance, to inform the company's technical approach.
Read full description
The company's core offering is a data platform that equips airlines, aircraft lessors, and carbon calculators with actionable metrics. This service enables clients to precisely measure, report, and ultimately reduce their environmental impact. By integrating a wide array of data sources—such as flight schedules, air traffic control information, and weather patterns—Estuaire's models can calculate the climate impact for every individual flight worldwide. This allows for a granular analysis that goes beyond simple CO2 output to include non-CO2 effects, which are a significant component of aviation's climate impact.
Estuaire operates on a B2B model, providing its data and analytics as a service to businesses within the aviation ecosystem. The platform helps clients comply with environmental regulations and meet their own sustainability targets by identifying specific operational improvements. Having secured backing from investors like XAnge and being part of the Station F ecosystem, Estuaire is positioned to expand its role in the industry's decarbonization efforts.
