Great to see BBC News reporting on our 2030 Sustainable Aviation Goals report. Goal 1 - Operation Blue Skies - calls on aviation leaders to establish ‘Living Labs’ by the end of 2025 to address uncertainties in #contrail avoidance, which could reduce the #climate impact of #aviation by up to 40%. Contrails act as a blanket 🛏 in our skies, typically covering around 1/1,000th of the Earth's 🌍 surface at any one time. Whilst each contrail only last hours ⌛ , they're constantly replaced by the exhausts of aircraft flying in sky. Whilst there's significant uncertainty (+/-70%), the rate at which the contrail blanket warms the planet (the Effective Radiative Forcing) is estimated to be 57 mW/m2 - that's the same warming rate as 32 billion tonnes of CO2 in the atmosphere ♨ (for context, roughly 12 months of emissions from all sectors combined). It's crucial that we urgently act to create Airspace-Scale Living Labs to have the capability to test, learn, and pivot whilst operating within a realistic airspace environment. 🔬 ✈ #NetZero #SustainableAviation #NonCO2 Whittle Laboratory Cambridge Institute for Sustainability Leadership (CISL) https://lnkd.in/e9XJSCzN

The results of a European study into the impact of a widebody jet flown with 100% sustainable aviation fuel show a substantial 56% reduction in the number of contrail ice crystals produced by unblended SAF compared to Jet A-1 fuel, reports Tony Harrington for GreenAir News. The project, involving Airbus, Rolls-Royce, the German Aerospace Center (DLR) and SAF producer Neste, was the third stage of the Emission and Climate Impact of Alternative Fuels (#ECLIF) programme, with in-flight and ground emissions tests taking place in 2021. They worked together to quantify the reduction in engine soot particles produced by a Rolls-Royce powered Airbus A350 fuelled by Neste and trailed by a DLR research aircraft. In certain weather conditions, airborne vapour freezes around soot particles emitted by aircraft engines, creating cloudy canopies of ice crystals which can trap heat in the atmosphere. #sustainableaviation #sustainableaviationfuel #aviationnonco2 Mark Pilling Christiane Voigt Hartwig Hagena Mark Bentall Alexander Kueper Alan Newby Philippe Gmerek Falk Dambowsky Heiko Stolzke Matteo Mirolo Florian Allroggen Steven Barrett Vincent de Haes Carlos López de la Osa Dimitar Nikov Marc Shapiro Jason Taylor Estuaire Jonathon Counsell Adam Durant International Air Transport Association (IATA) Marie Owens Thomsen Jill Blickstein Andrew Chen Dr. Alejandro Block Hemant Mistry Sarah Wilkin Roger Gardner https://lnkd.in/eD357-ap

✈️ 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

One of the areas where aviation is getting noticed and admonished, is ConTrails. As an Avgeek I love them. But they do represent pollution of some sort. Here is a good article to read on the topic of some of the current research being done. For true #avgeeks notice the aircraft that did the research were prototypes! https://lnkd.in/geSBGBxt #Contrails #Airbus #boeing

🔹A recent study by Airbus, Rolls-Royce, the German Aerospace Center and Neste has shown that the use of 100% sustainable aviation fuel (SAF) in commercial aircraft can significantly reduce global warming. Compared to conventional Jet A-1 fuel, SAF showed a reduction in soot particle emissions as well as a 56% reduction in ice crystal formation, thus offering a potential solution to mitigate the climate impact of aviation. This study, which also assessed the reduction of greenhouse gas emissions, highlights the importance of SAF in achieving net zero emissions targets in the sector, underlining its viability for broader use in commercial aviation.

“The results from the ECLIF3 flight experiments show how the use of 100 percent SAF can help us to significantly reduce the climate-warming effect of contrails, in addition to lowering the carbon footprint of flying – a clear sign of the effectiveness of SAF towards climate-compatible aviation”, said Markus Fischer, DLR Divisional Board Member for Aeronautics. https://buff.ly/4eM9BE8 #Airbus #Climate #FlightStudy #CO2 #nonCO2
