The aviation sector risks missing its 2050 net-zero target as passenger demand grows and low-carbon fuel development lags. UK and Australia’s "jet zero" councils aim to drive greener aviation. Mark Toon of Cardiff University / Prifysgol Caerdydd argues their focus on incremental innovation won’t meet urgent emissions goals. "Offering guilt-free, zero-emissions flights would be transformative. Whatever the market dynamics, the urgency of the climate crisis is clear. Jet zero organizations hold the key to unlocking the type of change needed to make aviation sustainable — but only if they rise to the challenge." 💡Read more about this and other views on the #energytransition at Kathari News Perspectives: https://ow.ly/Kzgk50UmNXo

Are you aware of the significant measures the aviation industry is taking to combat climate change? 🌍 Sustainable Aviation Fuels (SAFs) are quickly becoming a pivotal component in the industry's mission to reach net-zero emissions by 2050. • The ability of SAFs to reduce CO2 emissions by up to 80% compared to conventional jet fuel is transformative.✈️ What's truly notable is the vast advancements being made in: - Technological innovation - Scaling production - Encouraging cooperative efforts to expedite the adoption of SAFs As it stands, SAFs are compatible with existing aircraft and infrastructure. This compatibility greatly facilitates the transition.👏 This is no longer a mere vision, but a reality that's taking flight. This kind of shift has the potential to not only revolutionize an industry but also our planet - assuring a sustainable future for all flights.💚 As we navigate towards this future, I'd love to hear your thoughts on the role of SAFs in steering the aviation industry towards net-zero emissions. #SustainableAviationFuels #NetZeroEmissions #ClimateChange #AerospaceTechnology

Four steps towards more sustainable aviation: remove clouds formed by contrails; slow down flights, upgrade planes, and ensure they’re flying in their optimal range; scale up production of sustainable aviation fuel; and explore new technology (e.g. hydrogen airplanes)

✈️ UNDERSTANDING THE IMPACT OF AVIATION ON CLIMATE CHANGE Aviation, while only contributing 2.5% of global CO2 emissions, plays a significant role in climate change. Here's why: 1️⃣ Carbon Footprint: Air travel's individual impact on climate change is substantial, though it's only a fraction of total emissions. In 2018, aviation emitted 1.04 billion tonnes of CO2, representing 2.5% of global emissions. 2️⃣ Complex Impact: Beyond CO2, aviation affects climate through various pollutants like contrails, soot, and sulfur aerosols. These contribute to a complex mix of warming and cooling effects. Surprisingly, CO2 accounts for less than half of aviation's warming impact, with two-thirds (66%) stemming from non-CO2 forcings. Contrails, for instance, emanating from water vapor trails in aircraft exhausts, hold the largest share of this warming effect. 3️⃣ Challenges in Decarbonization: Unlike other sectors, decarbonizing aviation is particularly challenging. While innovative solutions like hydrogen fuel cells and electric planes are emerging, they're still in early stages. However, despite emissions growth, aviation efficiency has improved significantly over the years due to advancements in aircraft design, technology, and higher passenger load factors. Awareness is key in addressing the impact of aviation on climate change. Let's explore solutions and support initiatives towards sustainable air travel. Together, we can make a difference for our planet! 🌏💚 #climateaction #aviation #sustainability #climatechangeawareness #climatechange #airplanes #greenhouse #ghg

Can slowing down planes help cut aviation’s carbon footprint? 🛫 📚 A new study from the University of Cambridge suggests it can. By reducing flight speeds and improving contrail coordination, the aviation industry could significantly cut its environmental impact over the next five years. One of the strategies included in the study is to reduce flight speeds by 15%, reducing fuel burn by 5-7%. ⏰ On the other hand, this might add 50 minutes to a transatlantic flight. The university’s analysis indicates that current policies leave the aviation sector far from achieving its climate commitments. The report outlines realistic and sustainable steps that, if implemented, could put the industry back on track towards meeting net-zero emissions by 2050. What are your thoughts on this plan? #Aviation #NetZero #ClimateAction #GreenTech #GreenNews #CircularEconomy #Sustainability #WasteManagement #Resourcify

We already know that sustainable aviation fuel (SAF) reduces CO2 emissions, but a new study confirms that it also reduces the non-CO2 emissions that impact climate change like ice crystals and soot. https://bit.ly/4cdFHrt #sustainability #sustainableaviation

Let’s be honest. If you’re reading this, you do not need a re-telling of the hard facts: 💚 You know that the aviation industry is going to be incredibly hard to decarbonise. 💚 You know that despite the seemingly insurmountable challenge ahead of us, the industry is committed to the 2050 net zero goal and exploring many significant approaches. 💚 You know that if we do nothing, our current contribution of 2-3% to global emissions will increase to as much as 25% by 2050. Given the state of affairs, the question of what the industry can do about sustainability is rife with controversy, speculation and divided opinions. In such a scenario, an airline executive working in sustainability might be tempted to give in to hopelessness or despair. At SimpliFlying, we attempt to provide an antidote to such pessimism. Our inaugural Sustainable Aviation Outlook report offers hope, reassurance, answers and some helpful suggestions along the way. 🔥 Grab your digital copy at https://lnkd.in/dyNdGUCA Special thanks to our partners Cirium and ENVEST GLOBAL for the rich and comprehensive data that has further helped us paint a vivid picture of the current aviation landscape. #sustainableaviation #futureoftravel #airlines #netzero

One of the most significant events addressing 𝐧𝐨𝐧-𝐂𝐎𝟐 𝐚𝐯𝐢𝐚𝐭𝐢𝐨𝐧 𝐞𝐦𝐢𝐬𝐬𝐢𝐨𝐧𝐬, a critical issue for the #aviation industry, was held last month in Montreal. The symposium hosted by the International Civil Aviation Organization continues to have a lasting impact. The event, which featured Greg Smallwood from ENVISA, aimed to raise awareness among all stakeholders about the #climate and #environmental impacts of these emissions from aviation operations, while fostering collaboration between different parties. Following this symposium, which Envisa closely followed, it’s important to stay updated on the key issues (summarized below and in the carousel) surrounding non-CO2 aviation emissions. Global experts on the topic gathered to deliver presentations and engage in panel discussions, exploring the current state of knowledge on non-CO2 emissions, their impacts, and potential #mitigation strategies. Here are the key takeaways: * There are significant uncertainties associated with the production of non-CO2 emissions by aviation, the impact of these non-CO2 emissions on the climate, and the effectiveness of options such as: - fuel and engine technologies - flight diversions - proposed policy tools * A metric for gauging the benefits is urgently needed for establishing comparisons between potential actions, given the different timescales of CO2 and non-CO2 emissions. * The climate forcing due to contrails is being assessed by increasingly sophisticated models, and the gaps are being addressed as more measurement data on atmospheric conditions, fuel composition, and engine technology becomes available. * Several organizations are developing tools for innovative operations such as flight re-routing to avoid ice-supersaturated regions in the atmosphere, including changing altitude and/or diverting around the affected regions. * The 𝐀𝐍𝐂𝐄𝐍 𝐧𝐞𝐭𝐰𝐨𝐫𝐤 will aid in bringing experts together to achieve consensus on what is currently known and what gaps remain. #aviationemissions #NONCO2 #sustainability #climate #envisainsights

✈️”We will continue to fly." Watch Elisabeth Wetterlund, Professor of Energy Technology at Luleå University of Technology, talk about sustainable aviation fuel as one of the keys to a fossil-free aviation industry. "There are ongoing developments to reduce the climate impact of aviation. For example the EU requires increased usage of sustainable aviation fuel from 2% in 2025 to 70% in 2050," Elisabeth says. #SkyFuelH2 #aviation #sustainability
