End to end contrail & non-CO2 management

Actively %%reduce%% warming contrail formation

Leverage latest weather forecast models to identify Ice Super Saturated Regions (ISSRs) where warming contrails form and fly around them.

Our flight optimizer can help you unlock large climate impact savings with tailored fuel burn constraints. Some “win-win” situations can deliver both fuel and contrail savings and we aim to ensure full compatibility with your existing fuel efficiency initiatives.

Frequently asked questions

Why do contrails matter in aviation?

Aircraft cause two types of warming. The first via greenhouse gas emissions, and the second via contrails. Contrails have a warming impact when they grow into cirrus clouds that trap heat into the atmosphere that would otherwise escape.

How does Estuaire properly model contrail impact?

Due to the nuanced nature of contrail formation, we combine various data sources to model contrail impact on a per-flight basis. These sources include ADS-B flight tracks, high-resolution realization (HRES) meteorology from the new DWD two moments model, and the contrail cirrus prediction model (CoCiP) developed by the The German Aerospace Center (DLR).

What elements impact contrail formation?

Persistent warming contrail formation is a result of several specificities: atmospheric conditions called Ice Super Saturated Regions (ISSRs), cruise altitudes, the amount of soot emitted via engine combustion, and the particulate matter as a function of fuel properties. ISSRs are cold, humid regions in the atmosphere and not all flights fly through them. That's why adjusting flight profiles of only certain flights can have significant climate savings.

Are airlines disclosing these impacts?

Currently, the European Union is the only regulatory body requiring the disclosure of non-CO2 impacts, including contrails. It applies to flights within the European Economic Area, but may expand to any flight arriving or departing the EEA in 2027.

Can Estuaire help my airline reduce our climate impact operationally?

Yes, Estuaire's flight optimization product identifies contrail-avoiding flight levels and high-impact routes to support operational strategies that reduce total warming, not just CO2.
