Reduce the climate impact of your flights %%by mitigating contrails%%

Contrails can trap heat and significantly increase aviation's climate impact. By adjusting flight levels on certain routes, airlines can avoid forming long-lived contrails and instantly cut total warming on optimized flights. Typically, less than 5% of flights would be candidates to be optimized.

We analyze flight plans with real-time weather and flight conditions to identify contrail-forming segments and recommend minor altitude changes to avoid them, with minimal impact on fuel burn or scheduling.

No, our software-based solution recommends flight level adjustments via flight dispatch or directly to the cockpit.

Contrail avoidance typically requires small vertical adjustments, often fuel-neutral or with negligible fuel penalty for major climate savings. Estuaire can model trade-offs and optimize for climate benefit within operational and business constraints.

While uncertainty remains in measuring contrail impact, the scientific community undoubtedly agrees that enough knowledge has been built to start mitigating the harmful impacts of non-CO2 emissions. At Estuaire, we believe that waiting for absolute certainty before mitigating contrail impacts would be a mistake. However, this conviction should not come at the expense of higher CO2 emissions, whose impact in the atmosphere lasts longer.
