Definitely an interesting insight on emissions in high-altitude, that could be leading to even worse effects. Transport & Environment (T&E) super post!

Hmmm - not sure that new aircraft contrail more because they're designed to fly higher. More data required to convince me. I don't doubt that newer types were observed generating more contrails - I know and trust one of the authors of the paper - Marc Stettler However, although technology might have a small effect, I suspect the main cause of the new aircraft flying higher is the different relative positions of the two types in their respective family plans. The paper does not identify the 2 types - I think the older aircraft is a 767-300ER and the newer one a 787-8, based on the paper's description. The following also applies for the A350-900 and A330-300 (if they are the 2 types in the paper). If one of these guesses is correct, the 767-300ER cruise altitudes should be compared with 787-10's as both represent their type's sizing variants. The 787-8 uses the same wing as the -10 with much lower weights (so it flies higher) - just as the 767-200ER does. https://lnkd.in/eCT3-tPd

Heirloom Carbon: A New Hope in Climate Change Mitigation Heirloom carbon is an emerging concept that involves capturing and securely storing carbon dioxide (CO₂) from the atmosphere to help combat climate change. This approach aims to preserve carbon for future generations, much like a family heirloom, ensuring that it remains out of the atmosphere long-term. Several methods are employed to achieve this, including planting and managing forests, enhancing soil carbon storage, using marine plants, and implementing advanced technologies like direct air capture and carbon capture and storage. Geological methods such as enhanced weathering and carbonate formation also play a crucial role. The significance of heirloom carbon lies in its potential to provide sustainable, long-term solutions to reduce greenhouse gases, thereby mitigating global warming. However, the road ahead includes challenges like scalability, economic viability, and ensuring the permanence of stored carbon. Despite these obstacles, ongoing advancements and increased investment in this field offer hope that heirloom carbon could become a key strategy in global climate efforts, helping to secure a healthier planet for future generations. #Heirloom #CarconCapture #CO2Removal

A great news story: BCG is on track to halve our emissions intensity by 2025 and remove the remaining emissions by 2030. A classic example of reduce AND offset remaining emissions.

#Contrails, what they are and what we can do about them. There are more ways we can reduce aviation's #climateimpact in the AIA's 2030 Sustainable Aviation Goals at report.aiazero.org.

IETA and AlliedOffsets have published their joint forecast for the impacts of #CORSIA on the carbon markets. As a hard-to-abate sector, carbon offsetting is crucial to address the aviation industry’s residual emissions.     At Net Zero Climate Investments, we support the transition to global net zero with our high-quality emission reduction projects.

Impressive new technology but the numbers reveal quite how far it is away from being a climate game changer: 🚗 Removes emissions from less than 8,000 US cars (or 0.2% of registered vehicles in Houston) 💰 Costs $1,000 a ton 📈 Needs to scale 27x to 1m tons by 2030 and 1000x to 1bn tons by 2050 Full story by Ragnhildur Sigurðardóttir for Bloomberg Green https://lnkd.in/dRayK5Hy

The science is clear: Keeping 1.5°C within reach will require reaching #NetZero CO2 emissions by midcentury. 🚫🏭 Over 90 countries have set #NetZero targets. Never before has there been such ambition for achieving deep #EmissionsReductions. But target setting is just the first step.
