✈️ The Copenhagen Contrails Conference is almost here—time to get excited! ☁️

If you work in aviation, corporate sustainability, climate policy, or just want to geek out about one of the biggest untapped climate solutions, this is THE event for you.

We’ve got an incredible lineup of speakers, including some of the world’s leading contrail experts:

🌍 Marc Stettler (Imperial College London) will kick us off with a contrail masterclass, so we’re all on the same page from the start.

🛩️ Christiane Voigt (DLR) will examine how cleaner fuels can help mitigate contrails.

📡 Paul Hodgson (AIA, University of Cambridge) will outline the vision for scaling contrail management over the next 5-10 years.

But it doesn’t stop there! Airlines are already testing contrail mitigation strategies—we’ll hear firsthand from TUI Airline, DHL, and others about how they’re piloting these new ways of flying.

For the policy-minded folks, we’re diving into some of the biggest questions:

🛑 How do we manage uncertainty in contrail impact modeling?

🔎 Carrot or stick? What’s the right approach for regulating contrails?

Expect great discussions from leaders at top climate organizations, including:

💡 Andrew Chen (RMI)

💡 Diane Vitry & Carlos López de la Osa (T&E)

💡 Jayant Mukhopadhaya (ICCT)

💡 Matteo Mirolo (Breakthrough Energy)

💡 Aoife O’Leary (Opportunity Green)

💡 Anna Stratton (ClimateWorks Foundation)

And we can’t forget the tech innovators shaping the future of contrail management:

🛰️ Adam Durant (Satavia)

🛫 Alejandra Martin Frias & Raimund Zopp (Flightkeys)

📡 Julien Lopez (Thales)

💡 Maxime Meijers (Estuaire)

🌍 Nikhil Sachdeva (Roland Berger)

💡 Sebnem Erzan (Google)

🛫 Vincent de Haes (to70)

🚀 Plus, a special policy perspective from Dimitar Nikov, Policy Officer at EU’s DG CLIMA.

🔥 This is the conversation the aviation industry needs to have. And this is just a glimpse of what’s in store! There are many more speakers and sessions covering everything from operational strategies to cutting-edge modeling.

Go to Blue Lines’ educational website to explore contrails in depth.

(As regular readers of the Blue Lines newsletter know, contrails are the thin white streaks that airplanes sometimes leave behind in the sky, created from water vapor and engine soot. Some of these condensation trails can spread out and form high-altitude ice clouds (cirrus), which reflect some of the sun’s energy back into space while also trapping outgoing energy in the atmosphere, leading to a net warming of our planet equivalent to 1-2% of human-induced global warming. However, studies and trials indicate that it is relatively simple to avoid most warming contrails by flying around areas in the atmosphere that are prone to contrails. This climate solution—often referred to as contrail management or contrail avoidance—is what Blue Lines advocates for and hopes to see implemented globally.)

See you soon.
