Sustainability In The Air

How FLIGHTKEYS promises major climate gains at a minimal cost

Jul 18, 2024

Alejandra Martín Frías from FLIGHTKEYS discusses contrail avoidance in aviation to reduce climate impact, highlighting simulations showing up to 73% reduction in contrail energy forcing with less than 0.11% increase in costs. The challenges of contrail avoidance, the industry's hesitance, and the importance of non-CO2 emissions are explored.

Quick takeaways

Contrail avoidance is crucial for aviation sustainability due to its significant impact on non-CO2 warming effects similar to CO2 emissions.

Flightkeys' research shows reducing contrails can have a substantial impact at minimal cost, offering a cost-effective solution for airlines.

Despite promising results, airlines exhibit reluctance to adopt contrail avoidance due to operational complexities, highlighting the need for further studies and collaboration.

Deep dives

The Significance of Contrail Management in Aviation

Contrail avoidance is being recognized as a crucial element in aviation sustainability efforts due to its impact on non-CO2 warming effects similar to CO2 emissions. Studies suggest contrails are as warming as CO2 emissions, making their reduction a priority for airlines globally.

In this episode, we talk to Alejandra Martín Frías, Head of Sustainability Research at FLIGHTKEYS, who shares insights into the company’s research on contrail avoidance and its potential impact on aviation sustainability.

Condensation trails, also known as contrails, are long, thin clouds that often form behind an aircraft in cold and humid conditions when water vapour freezes around small dust and soot particles from the engine. Although they look harmless, contrails are made up of small ice crystals that trap heat in the earth’s atmosphere and contribute to global warming.

Frías delves into the complexities of contrail formation and its impact on climate, highlighting that non-CO2 emissions from aviation may be as significant as CO2 emissions in terms of climate impact. She explains the challenges of implementing contrail avoidance strategies, including weather unpredictability, operational complexities, and the industry’s hesitance to participate in non-CO2 emissions monitoring.

Recently, FLIGHTKEYS was part of a study that simulated contrail avoidance for about 85,000 flights. The study, published in February 2024, analysed two weeks of American Airlines flights in June, and two weeks in January. Frías shares that the study demonstrated significant reductions in contrail energy forcing (up to 73%) with minimal increases in fuel consumption and overall costs (less than 0.11%!).
