Welcome to Sustainability in The Air, the world’s first podcast dedicated to sustainable aviation. The show is brought to you by SimpliFlying, the world’s leading aviation marketing strategy firm.

The realm of sustainable aviation is going through a phase of rapid development - from new technologies to sustainable aviation fuel. Airline, airport and travel executives often struggle to make sense of what seems to be a wild-West scenario.

It's about time someone took the leadership to help make sense and guide the industry toward best practices for getting to net zero.

Welcome to the first episode of Sustainability In The Air podcast. We launch the podcast on Earth Day 2022 with the discussion between Shashank Nigam, CEO at SimpliFlying and Tony Douglas, Group CEO at Etihad Aviation Group. 
 
 Going forward, trust will require airlines, airports and the entire industry to share how to build a sustainable future. No airline is doing as much as Etihad Airways when it comes to taking measures proactively on sustainability and also communicating about them. In the interview, Tony shares with us the journey of sustainability that Etihad has been on, including the stories of The Sustainable 50 aircraft, why he's betting on carbon offsetting as an immediate solution and the launch of the world's first green loyalty program.

CarbonClick CEO Dave Rouse and COO Michelle Noordermeer share how radical transparency helped them deliver market leading carbon offsetting programs to top airlines. They open up about the mistrust around planting trees and how it can be overcome. Finally, they share innovations in the field that make carbon offsetting possibly one of the only effective and scalable methods achieving carbon neutral flight today.

The United CEO has committed to twice as much SAF as the rest of the world’s airlines combined, has invested in multiple green technology startups and is personally motivated to leave the world a better place for his seven kids. We deep dive in this engaging conversation.

Co-Founder of Universal Hydrogen John-Paul Clark dives deep into how hydrogen is a strong medium term solution.

JetBlue Technology Ventures is unique because it's a corporate venture fund owned by an airline with a mission to further the goals of the entire industry - none of which is more important today than a net-zero future. Amy Burr dives deep into how she and her team are identifying technologies that will make flying greener and perhaps magical too.

Dr Patrick Gruber, CEO of Gevo, deep dives into using alternative feedstock, blockchain technology and building trust through transparency.

Greg McDougall discusses early adoption of technology, flying the world’s first  fully-electric commercial airplane and the electric Beaver.

Representing the interests of airports and airport operators across the world, Airports Council International (ACI World) fosters collective action within the industry. With nearly 712 members, and operations spanning 1,925 airports in 171 countries, ACI World contributes to the safety, security and sustainability of global aviation.

In this episode, we talk to ACI World’s Director General Luis Felipe de Oliveira who explains how, as significant emitters of greenhouse gases, airports play a pivotal role in aviation’s journey to net zero. 

On average, airports account for roughly 5% of aviation’s carbon footprint. Airports have varying carbon footprints due to their geographical, cultural and economic intricacies. This, as Luis Felipe puts it, makes each airport a mystery that needs to be understood and unlocked in its specific context. 

We'll learn about how ACI World is nudging airports to be more sustainable through their six-level carbon accreditation programme; the promise and pitfalls of hydrogen and sustainable aviation fuel; the solar energy and green building ecosystem; and the need for the industry to communicate its achievements and challenges as one cohesive unit.

eVTOLs (electric vertical takeoff and landing) or ‘air taxis’ refer to aircraft that use electric power to take off and land vertically, and are particularly useful in urban areas afflicted with traffic congestion.

In this episode, we talk to Adam Goldstein, CEO and Founder at Archer Aviation. He shares how the company focuses on designing and developing eVTOLs, which they believe will “unlock the skies” and enable everyone to reimagine how they live, travel and manage time. 

Goldstein says these vehicles – which can carry four passengers and a pilot – will not only change the way people move but also allow people to get a lot of time back. “Imagine the trips that you've been taking in your car – it would take you 60, 90, even 120 minutes of sitting in traffic. But you could instead fly to your destination in five or 10 minutes”, he asserts. Such a future is actually closer than we think. Archer aims to get its aircraft certified by the end of 2024 and, along with its partner United Airlines, will begin commercial eVTOL flights in 2025.

If you LOVED this episode, you’ll also love the conversation we had with United Airlines’ Scott Kirby on how the airline is pushing the sustainability envelope. Check it out here.

As the industry leader in aviation analytics, Cirium assists the aviation industry in predicting future trends through its rich datasets that date back to 1947 and cover over 400,000 aircraft!

In this episode, we talk to Jeremy Bowen, CEO at Cirium. He shares how the company is empowering the industry to reach a more sustainable future with the most accurate aircraft emissions data.

Cirium has a wealth of data that airlines can use today. Their highly-accurate Global Aircraft Emissions Monitor is a valuable starting point for any airline that wants to seriously plan emissions reduction – and, eventually, hit net zero. After all, without the data to measure current baselines, any effort to go green will be a shot in the dark.  

We’ll also learn about the complex data set underlying the emissions calculator; how Cirium ensures their data is transparent, independent of bias and validated; why the future of corporate travel may include carbon budgets; and how one company switched a large corporate travel account from one airline to another based on carbon efficiency considerations.

If you LOVED this episode you’ll also love the conversation we had with International Council on Clean Transportation’s Dan Rutherford on the data behind sustainability and the trajectory airlines and governments need to follow to get to net-zero emissions. Check it out here.

SATAVIA wants to solve a majorly ignored aspect of aviation’s climate impact

In this episode, we talk to Adam Durant, Founder & CEO of SATAVIA, about the groundbreaking work being done in the field of contrail reduction and its implications on the environment.

Contrails are the long, thin clouds that often form behind an airplane in cold and humid conditions when water vapor freezes around small dust and soot particles from the engine. Although they look harmless, contrails are made up of small ice crystals that trap heat in the earth’s atmosphere and contribute to global warming – one study suggests contrails are responsible for as much as 57% of aviation’s warming impact. 

Durant talks about how addressing contrail formation is an important sustainability problem that can be tackled effectively with current technology and resources. He says that only “persistent” contrails, formed by about 5% of flights, are at fault. Moreover, he emphasises that not all contrails are harmful; some even have a cooling effect. He suggests a strategic approach, avoiding contrails that cause warming while possibly utilising those that have a cooling effect. 

Overall, while delving into the fascinating science of contrails and the technical details of how SATAVIA’s software helps airlines such as Etihad and KLM avoid contrail formation, Durant stresses the importance of looking beyond carbon emissions to fully grasp and manage the aviation sector's impact on climate change.

If you LOVED this episode, you’ll also love the conversation we had with ex-Etihad CEO Tony Dougas who shared how Etihad is paving the way for the entire industry to move a step closer to net-zero. Check it out here.

In our first-ever bilingual episode, we talk to Preeti Jain, Head of Net Zero Transition Program at the International Air Transport Association (IATA). Jain provides an in-depth look at the challenges and opportunities in scaling up sustainable aviation fuel (SAF) to help aviation achieve its goal of net zero emissions by 2050. 

The interview is presented in two parts: English followed by Hindi. 

Jain discusses the current SAF landscape, highlighting the stark mismatch between demand and supply. Emphasising the need for greater SAF production, she estimates that a 1000-fold increase is required by 2050, amounting to roughly 300 new SAF plants each year. This rapid scale-up, however, is hindered by several challenges: inconsistent policy support, high capital costs and under-developed feedstock supply chains.

IATA’s strategy for overcoming these challenges involves a multi-pronged approach focusing on feedstocks, technology development, policy support, and collaboration across stakeholders. Jain emphasises the need for policies that encourage SAF production and adoption, and commends the U.S. Inflation Reduction Act and California’s Low Carbon Fuel Standard as good examples. She sees potential in leveraging existing refinery infrastructure for SAF production, and expects SAF’s cost to decline over time as more facilities are deployed and technologies mature.

Jain also discusses the potential for SAF to deliver benefits beyond emissions reductions, such as improved energy security and rural economic development, particularly in emerging economies with large agricultural sectors. She also emphasises the critical role of collaboration across the aviation industry, governments, and civil society to build a thriving SAF ecosystem.

In this episode, we talk to Akshat Rathi, award-winning senior climate reporter for Bloomberg News. Rathi is the host of Bloomberg’s podcast Zero that explores the policies, tactics and clean technologies pushing for a zero emissions future. He is also the author of the book Climate Capitalism, which tracks the unlikely heroes driving the fight against climate change.

Rathi argues that for years the aviation industry has sheltered behind the label of being “hard to decarbonise”, which is not only a misconception, but has also stalled the industry’s progress towards net zero emissions. He advocates for correctly pricing flights to account for their true environmental cost, a move that could bring an end to “ridiculously” cheap flight tickets.

Rathi also discusses the potential of sustainable aviation fuels (SAF) in decarbonising aviation and the need to overcome cost barriers through policy support and corporate commitment. Further, he delves into the role of electric aviation in transforming short-haul travel and regional aviation.

In Rathi’s view, the aviation industry stands at a crossroads, and the choices made now will determine not just the future of flying, but our ability to meet global climate targets. As he puts it, “We have to start to think about those technologies, because we do need decarbonised solutions.”

In this episode, we talk to Ali Warrington, Senior Campaigner at Possible, a UK-based climate charity that enables people to take practical action on climate change. 

Possible has been at the forefront of climate action and has been instrumental in lodging formal complaints against airlines like Virgin Atlantic and British Airways for their greenwashing claims. The charity, along with other climate groups has also taken the  UK government to court over its Jet Zero strategy.

Warrington believes that the aviation industry’s current approach to sustainability is dramatically insufficient. She points out the limitations of the current decarbonisation solutions – including sustainable aviation fuels (SAF), hydrogen, and electric aircraft – and expresses scepticism about their scalability and effectiveness. She also expresses concern about the enormity of resources, both natural and monetary, that would be needed to make these solutions a reality. Ultimately, Warrington states, demand reduction is the only pragmatic way to cut aviation’s share of emissions.

Warrington also points out the inequality in air travel in the UK – just 15% of people take 70% of flights annually, with half the population not taking any flights at all. She supports the idea of a frequent flyer levy, to progressively tax individuals on the number of flights they take. She also emphasises the need for a systemic change in global travel infrastructure, and advocates for a shift towards train travel or other low-carbon transportation options, whenever possible.

In this episode, we talk to Alejandra Martín Frías, Head of Sustainability Research at FLIGHTKEYS, who shares insights into the company’s research on contrail avoidance and its potential impact on aviation sustainability.

Condensation trails, also known as contrails, are long, thin clouds that often form behind an aircraft in cold and humid conditions when water vapour freezes around small dust and soot particles from the engine. Although they look harmless, contrails are made up of small ice crystals that trap heat in the earth’s atmosphere and contribute to global warming. 

Frías delves into the complexities of contrail formation and its impact on climate, highlighting that non-CO2 emissions from aviation may be as significant as CO2 emissions in terms of climate impact. She explains the challenges of implementing contrail avoidance strategies, including weather unpredictability, operational complexities, and the industry’s hesitance to participate in non-CO2 emissions monitoring.

Recently, FLIGHTKEYS was part of a study that simulated contrail avoidance for about 85,000 flights. The study, published in February 2024, analysed two weeks of American Airlines flights in June, and two weeks in January. Frías shares that the study demonstrated significant reductions in contrail energy forcing (up to 73%) with minimal increases in fuel consumption and overall costs (less than 0.11%!).
