New research from Imperial College London and the German Aerospace Center (DLR) reveals that more efficient wide body aircraft tend to generate contrails with longer satellite-detectable lifetimes 🛫 This is due to their operational characteristics and higher flying altitudes These findings suggest a complex trade-off between aircraft fuel efficiency and climate impact, as longer-lived contrails can contribute more significantly to climate change 🌎 👇 Link in first comment Edward Gryspeerdt Marc Stettler #contrails #science #summerread ------------------------------------------------------------------------ 📸 : Imperial College

Condensation trails — or contrails — created by aircraft flying through cold and humid air can significantly warm the climate. Most contrails dissolve within a few minutes, but in certain conditions, they can persist in the atmosphere, spread out, and become clouds that trap outgoing heat. This represents an additional climate impact alongside aviation’s direct carbon emissions. In recent years, technologies and methods have been developed to predict and avoid some of the warming effects created by contrails. Prediction models can inform operators of the optimal flight path to avoid contrails while limiting potential additional carbon emissions. These efforts can be validated by satellite imaging, ground-based monitoring, and pilot reporting to improve model accuracy. There are additional challenges that can only be overcome through continued collaboration by stakeholders from across the aviation industry. RMI’s Contrail Impact Task Force has been working to share and expand on the latest science on the climate impact of contrails. Their latest comprehensive report explores potential contrail solutions and identifies potential barriers to implementing those solutions.

We are thrilled to have played a role in advancing RIVE Private Investment's sustainability strategy The diverse assets in RIVE's portfolio inspired us to innovate further, enhancing our flight tracking capabilities and developing advanced models for APU and turboprop utilization to accurately measure climate impact Notably, RIVE's fleet includes aircraft that support the social pillar of ESG, such as ambulance 🚑 and firefighting 🔥 aircraft We hope this comprehensive baseline will resonate within the organization and we look forward to our next steps together !

🌍 More data on aviation contrails ! #regulation ❓ Did you know ❓ ... 🛫 In 2023, the air route with the most contrail climate impact is 🇪🇸 Madrid - Bogota 🇨🇴 ✖ 3️⃣ In 2023, the route where contrail impact was the greatest vs direct CO2 emissions is 🇬🇧 London Gatwick - Gran Canaria 🇪🇸 Next year, the European Commission will start collecting data on one of the greatest impact that aviation has on climate change : contrail clouds produced by aircraft, which occasionally persist and greatly affect temperatures On each route, the times of departure ⏱ , the aircraft types 🛩 and type of fuel ⛽ greatly affect this contrail impact, more data below 👇 Do you have a route in mind ? Happy to check it for you #flight #sustainability #nonCO2 #MRV

✈ It matters more than you think what time of the day you fly 🌎 It's a known fact that #aircraft release the same amount of #CO2 regardless of their departure time. However, the #contrails they sometimes produce have a #climateimpact that's roughly equivalent to the CO2. What's interesting is that only a fraction of aircraft contribute significantly to this warming, and their contribution is influenced, in part, by the time they take off. French tech company Estuaire recently released a comprehensive analysis of worldwide flights in 2023, running them through a contrail prediction model to see which caused contrails and how big their impact was compared to local airport departure times. The picture is very clear. Contrail warming is at its highest for departures in the late afternoon and bottoms out in the early morning. It all depends on when contrails are warming and when they are cooling the planet. See more in the first comments below.

Contrail Opportunity Index Already dealing with huge challenges, airlines face a mammoth task to achieve their net zero targets, and are in urgent need of solutions. Reducing contrails, which account for a significant proportion of the sector’s total radiative forcing impact, offers a far more immediate upside opportunity. In this paper we draw on fresh research to quantify and understand that opportunity in the context of ongoing industry initiatives.

Yesterday, we had the opportunity to present our work to Damien Cazé, the Managing Director of the Direction Generale de l'Aviation Civile (DGAC) - the French Civil Aviation Authority We discussed several key topics: 1️⃣ The upcoming non-CO2 regulation and how our data platform supports the mitigation of warming contrail clouds 🌪 2️⃣ The inspiring scientific publications from Climaviation and the IPSL-Institut Pierre-Simon Laplace 🔬 3️⃣ The urgent need to intensify operational efforts by launching large-scale contrail avoidance trials 🛫 We would like to thank Frédéric Solano, Sandra Combet, and the Agence de l'Innovation pour les Transports for this opportunity For the next two weeks ahead of the Olympic Games in Paris, you can check the [Mobilités Innov'] exhibition and visit us at the Paris heliport along with Ascendance, AURA-AERO, HyLight, Turbotech Aero

🇪🇺 🛫 The European Commission is asking airlines to monitor their non-CO2 effects starting next year 🔈 A public consultation on this plan is open until July 29th What's the plan ? 🌍 Scope : Intra-european flights only initially 🌿 What : CO2, Contrails and NOx emissions 💻 How : Through an automated tool In preparation for this effort, I used Estuaire data to analyze the top 🔟 air routes within the EU, considering both CO2 emissions and contrails as factors of climate impact. This approach effectively accounts for a significant portion of the climate impact ✈ These 10 routes accounted for ~17,000 flights in 2023 👇 See the result on the last page below, the longer 🇪🇸 > 🇬🇧 routes are particularly impactful #sustainability #contrails #nonCO2 #regulation
