Problem
The aviation industry faces increasing pressure to reduce its environmental impact, encompassing CO2 emissions, non-CO2 effects like contrails, and lifecycle considerations. Airlines, lessors, and investors need comprehensive data and analytics to make informed decisions, comply with regulations, and achieve sustainability goals. Existing carbon calculators often lack the breadth to address these complex factors.
Solution
Estuaire provides a software platform that analyzes the environmental impact of commercial aircraft flights, processing data on CO2, NOx emissions, contrail formation, and aircraft lifecycle. By integrating flight positions, weather data, aircraft ownership details, and passenger load factors, Estuaire generates a comprehensive environmental impact dataset. The platform enables users to monitor climate impact, simulate decarbonization levers such as next-generation aircraft and sustainable aviation fuels (SAF), and plan a cost-optimized decarbonization journey. This allows aviation stakeholders to make data-driven decisions, comply with EU-ETS and CORSIA regulations, and implement effective sustainability strategies.
Target Audience
Estuaire targets airlines, aircraft lessors, aviation investors, and carbon analytics firms seeking to monitor, plan, and reduce the environmental impact of aviation. Airports can also use the platform to comply with Airport Carbon Accreditation (ACA) requirements.
