Reducing plane 'contrails' can help climate - study confirms A groundbreaking research conducted by the University of Cambridge, Aviation Impact Accelerator (AIA), unveils potential strategies for combatting climate change within the aviation industry. The study indicates that by minimising the formation of #contrails - persistent clouds created by aircraft flying through cold and humid airspace - we could reduce the impact of aviation on global Green House Gas heating by 40%. Contrails created by aircraft are proven contributors to raising ground temperatures due to their blanket effect in the sky. It is estimated that one in every 30 flight miles produces these persistent contrails. Taking advantage of atmospheric forecasts and data to reroute aircraft away from such flight paths could significantly alleviate the climate impact, the researchers suggest. The University of Cambridge study found one in 30 flight miles generated a "persistent" cloud when flying through particularly cold and humid airspace and suggests planes avoid these by rerouting at key points in flight paths. Prof Rob Miller, director of the university's Whittle Laboratory, said: "Aviation stands at a pivotal moment, much like the automotive industry in the late 2000s." The joint study, in collaboration with the Cambridge Institute for Sustainability Leadership, further recommends the implementation of 'living labs' or international trials to test the potential impact of these strategies. The aim is to facilitate the adoption of these solutions by the airline industry within the next five years. Additionally, the researchers emphasize the need for other comprehensive measures such as instituting system-wide efficiency gains to halve the entire aviation sector's fuel consumption by 2050, improving policies around sustainable aviation fuels, and implementing more research into potential hydrogen-powered aircraft. While the sector is striving to achieve net zero by 2050, it is apparent that more deliberate and aggressive actions are required to curtail the anticipated doubling of the aviation sector's climate impacts by 2050. #SustainableAviation #EcoFriendlyTravel #CambridgeResearch #AviationImpact #ClimateChange #Research #NonCO2 https://lnkd.in/dX7QjaHE

How Will #DualTacticsDrive Carbon Emission Reduction in #Aerospace? The future of sustainable aviation relies on a combination of groundbreaking technologies like hydrogen-powered and #electricaircraft, as well as the scaling of #SustainableAviationFuels. These innovations will revolutionize short-haul and urban air mobility, helping the industry achieve net-zero emissions targets and paving the way for greener skies by 2035 and beyond. #SustainableAviation #CarbonReduction #NetZeroAerospace #GreenSkies #SAF #ZeroEmissionAircraft #HydrogenAviation #ElectricAviation #CleanEnergy #FutureOfFlight

✈️ Airbus, alongside Rolls-Royce, DLR, and Neste, successfully conducted the world's first in-flight study using 100% sustainable aviation fuel (#SAF) on both engines of a commercial aircraft. The study revealed a significant reduction in soot particle emissions* and contrail ice crystals**, which can decrease aviation's climate impact by 26%. This breakthrough demonstrates SAF's potential to mitigate both CO2 and non-CO2 emissions, marking a crucial step towards decarbonizing air transport. *Soot particle emissions are tiny, black carbon particles released into the atmosphere from the incomplete combustion of fossil fuels and biomass. These particles can contribute to air pollution, climate change, and respiratory issues in humans. **Contrail ice crystals are clouds formed from the water vapor emitted by aircraft engines at high altitudes. When these water vapor molecules freeze around tiny particles in the exhaust, they form ice crystals, which can sometimes persist and spread out, potentially affecting climate by influencing cloud cover and reflecting sunlight. #SustainableAviation #SAF #Airbus #AviationInnovation For more details, read the full press release (https://lnkd.in/eEJXw5mq).

In-flight measurements from an A350 aircraft using 100% sustainable aviation fuel (SAF) show a significant reduction in soot particle emissions and formation of contrail ice crystals compared to using conventional aviation fuel Global model simulations estimate 26% reduction in contrails' climate impact when using 100% SAF https://lnkd.in/eKYjYCb3

100% Sustainable Aviation Fuel Cuts Emissions and Contrails – A Brave Step Towards Net-Zero 2050 Recent groundbreaking in-flight studies on the use of 100% Sustainable Aviation Fuel (SAF) have revealed significant reductions in non-CO2 emissions, including the notorious contrails. With SAF estimated to contribute 65% of the emission reductions needed for aviation to achieve net-zero by 2050, this innovation is nothing short of revolutionary. But what truly sets this research apart? The industry’s fearless approach to science – flying Airbus A350s through high turbulence zones to obtain live data. Dive into how these daring missions are paving the way for a greener aviation industry. Contrails, which form ice crystals and contribute to global warming, have long been a challenge. However, the latest research proves that using SAF can significantly reduce contrail formation, cutting down another major source of aviation’s environmental impact. For the first time, in-flight tests on commercial aircraft using 100% Sustainable Aviation Fuel (SAF) have shown dramatic reductions in non-CO2 emissions, including soot particles and contrail ice formation. Compared to conventional Jet A-1 fuel, the use of SAF reduced ice crystal formation by 56%, significantly lowering the climate-warming effect of contrails. Global climate models estimate that using 100% SAF can reduce contrails' climate impact by 26%. These findings are pivotal, as SAF is projected to contribute 65% of the emission reductions needed for aviation to reach net-zero by 2050. https://lnkd.in/dzrv8ivv Credits/Congrats to: - Neste MY Renewable Jet Fuel - Rolls-Royce - Airbus - German Aerospace Center (DLR) #SAF #sustainableAviation #Aviation #contrails #SustainableAviationFuel #ECLIF3 #Decarbonization

♻ As the world strives to make aviation more sustainable, we often focus on fuel efficiency and alternative fuels. However, it's essential to recognize the significant influence of weather, especially wind conditions, on aircraft emissions. This is why we joined forces with @TU Delft to investigate the correlation between flight emissions and weather conditions. By including space-based ADS-B and Spire Weather upper-wind data, the research led by Dr. @Junzi Sun highlighted the importance of including this data in CO2 assessment models and demonstrated the potential for accurate emission assessment at the flight level.

🌍✈️ Transforming Aviation with Flexible Use of Airspace (FUA)! ✈️🌍 Before FUA, rigid airspace restrictions by many countries forced aircraft to follow indirect routes, leading to unchecked increases in CO2 emissions. These restrictions often caused longer flight times, higher fuel consumption, and greater environmental impact.With the advent of FUA, the landscape of aviation has changed dramatically: Seamless Coordination 🤝: Enhanced collaboration between military and civil airspace controllers allows for dynamic airspace sharing. Direct Routing 🛫: Aircraft can now fly more direct routes, significantly reducing travel distance. Reduced CO2 Emissions 🌿: Shorter routes mean less fuel burned and lower emissions. Decreased Congestion 📉 Better airspace management reduces traffic and eases the workload on air traffic controllers. But there's more work to be done. We need increased cooperation and coordination among countries to make aviation even greener, safer, and less restrictive. After all, aviation plays a crucial role in saving our planet from global warming.Let's unite for a smarter, greener future of aviation! 🚀#Aviation #Environment #Sustainability #Innovation #AirTrafficControl #GreenAviation #CO2Reduction #Efficiency #FutureOfFlight
