Sustainable Skies World Summit’s Post

We encourage our members to read the latest study from 4AIR as it sheds light on a critical topic for the business aviation community: non-CO2 emissions. While CO2 emissions are often the focal point of aviation’s environmental impact, research shows these emissions could account for only one-third of the industry's climate effect. The majority stems from high-altitude NOx emissions and contrail-induced cirrus clouds. To better understand business aviation's contribution, 4AIR conducted the largest flight-by-flight analysis of contrail and NOx emissions. 6,000+ flights and 27,000+ flight hours were examined using historical weather data and the CoCiP contrail prediction model. While this data is not meant to be representative of the entire business aviation industry, particularly as it covers only a non-representative sample of the aircraft types, mission profiles, and geographic concentration that business aviation covers, some of the key findings for business aviation are set out below: ✅Contrail mitigation in business aviation: There is a significant opportunity to reduce contrail impacts in Business aviation, potentially with minimal CO2 tradeoffs or even savings. ✅Substantial impact with minimal adjustments: Adjustments on just 50 flights out of 16,888 would have reduced the non-CO2 impact from this sample by more than 50% overnight. ✅Complexity of climate optimisation: A perfectly climate optimised flight will always be difficult in aviation due to the impacts aviation has, that unlike CO2, are not linearly related to the consumption of fuel and depend on background atmospheric conditions. ✅Focus on high-impact flights: Understanding the regional, seasonal, and altitude-dependent impacts of aviation will help to target flights with the biggest impact and better design effective operational or technological solutions.

The International Air Transport Association (IATA)'s Comparative Review of Aviation Net Zero Co2 Transition Pathways shares some interesting findings, including " In terms of absolute emissions reductions by various mitigation options, we found that the mitigation potential of a given option is determined again by the purpose of the roadmaps". It also states that "Sustainable Aviation Fuel (SAF) is assumed to deliver the highest emissions savings in the energy transition of the aviation sector to reach net zero by 2050", ranging between 24-70% reduction, highlighting the importance of #SAF in coming years of sustainable aviation.

Amazing to see the BALIS 2.0 Project featured on Aviation International News. After we announced the great news, our CEO Josef spoke to Charles Alcock about the future of the project, and how it is crucial to invest in alternative fuel sources if we want to succesfully decarbonize the aviation industry. Prof. Dr.-Ing. Josef Kallo discusses how in the long term, prioritising SAF is "a false hope" and will won't result in emission-free aviation, hindering our climate change efforts.

💡Can we reach our 2050 climate goals? The aviation industry faces significant challenges in achieving climate-friendly or even climate-neutral flying by 2050, according to a report from the Office for Technology Assessment at the German Bundestag (TAB). The report emphasizes the need for a mix of technologies: 🔌electric propulsion 🛫sustainable fuels 🌿green hydrogen ⛽fuel optimization ✈️aircraft efficiency improvements However, achieving climate-neutral aviation by 2050 seems unlikely without more drastic measures such as taxation or quotas. Despite efforts to develop sustainable aviation fuels and alternative propulsion technologies, significant hurdles remain, including technical complexity, scalability, and infrastructure challenges. At CAPHENIA, we're preparing for our debut in the sustainable aviation fuel industry with our renewable kerosene! Get ready to take-off with us!

Important commentary from Chris Lyle on the aviation emissions problem. ✈️ Capping aviation emissions is crucial to meet climate goals, given the limitations of sustainable aviation fuels (SAF) and alternative propulsion technologies. Despite technological and operational advances, they won't suffice. Emissions capping at airports, directly targeting emissions rather than flight numbers, is proposed as a viable solution.

🛫 Successful Take Off! New Policy Brief on Aviation is Out. Did you know that aviation accounts for 2.5% of all global and 5% of the EU’s total annual CO2 emissions and is the fastest-growing emitter in the transport sector? While efforts are being devoted to reducing the sector’s emissions, both globally and in the EU, aviation is not yet on track for net zero. Today’s European regulatory frameworks are crucial to shaping the sector’s progress toward net zero. Therefore, our five policy recommendations are:  🚄 Foster robust alternatives to short-haul flights 💰 Leverage carbon pricing for a sustainable aviation transformation 🔬 Invest heavily in research, development, demonstration, and innovation 🖋 Introduce ambitious, yet realistic, SAF mandates with clear sub-targets for Power-to-Liquid (PtL) fuels ☁ Tackle aviation’s non-CO₂ emissions head-on, especially contrails Learn more about how to ensure European aviation not only aligns with Europe’s 2050 carbon neutrality objective but also mitigates non-CO2 effects, addressing the sector’s total warming impact, in our new policy brief below!

Aviation's sustainability journey encompasses understanding Scopes 1, 2, and 3 of the Greenhouse Gas Protocol: direct, indirect, and supply chain emissions. Yet, Scope 4, often overlooked, holds significant importance. Scope 4 emissions, also known as avoided emissions or positive impacts, present both opportunities and controversies in aviation's environmental discourse. In our latest ab initio primer, we delve deep into the nuances of Scope 4 emissions, distinguishing genuine low-carbon efforts from greenwashing tactics. As aviation strives towards greater sustainability, it's crucial to discern between meaningful actions and superficial claims. Join us in exploring the complexities of aviation sustainability and uncovering strategies to effectively manage emissions in the industry. Stay informed and engaged as we navigate towards a greener future for aviation.

The aviation sector stands at a crucial crossroads, with only about 10% of the global population currently flying, a number set to rise as incomes increase. However, this growth brings challenges: aviation accounts for around 2.5% of global CO2 emissions, and we risk falling short of our net-zero targets by 2050 without immediate action. Recently, during the Transatlantic Sustainable Aviation Partnership at MIT, representatives from the UK, US, and EU unveiled a bold five-year plan aimed at achieving net-zero emissions by 2050. This plan outlines four key Sustainable Aviation Goals (SAGs) that focus on immediate action and long-term technological advancements: 1- Operation Blue Skies: Establishing Airspace-Scale Living Labs by 2025 to optimize airspace operations and enhance sustainability. 2- Systems Efficiency: Governments must commit to driving systems-wide efficiency improvements, unlocking gains through collaborative strategies by 2030. 3- Truly Sustainable and Scalable Fuel: Reforming Sustainable Aviation Fuel policies to enable scalability beyond biomass by incorporating carbon-efficient synthetic production techniques by 2030. 4- Moonshots: Launching experimental demonstration programs to scale transformative aviation technologies, generating vital data and expertise for deployment by 2030. These goals require immediate collaboration between governments, industry leaders, and policymakers. By addressing both existing technologies and pioneering innovations, we can steer the aviation sector toward a sustainable path. #Sustainability #Aviation #NetZero #Innovation #ClimateAction #SustainableAviation
