How Microsoft built the corporate playbook for scope 3 decarbonisation

Épisode 147

jeudi 13 novembre 2025 • Durée 40:49

In this episode, we speak with Julia Fidler, former Director of Market Development for Energy, Connectivity, and Sustainability at Microsoft, who shares how the company built partnerships that are reshaping corporate approaches to scope 3 emissions.

Fidler discusses:

How Microsoft’s early carbon fee on scope 1, 2, and 3.6 emissions created the foundation for treating business travel not just as a measurable category, but as a gateway to solving fuel emissions.
How Microsoft’s Sustainability Grant Program supported early exploration of emerging SAF markets through seed funding for consulting guidance and partnerships, creating a model for corporate innovation in hard-to-abate sectors.
Why Microsoft chose to support the most expensive SAF pathway (e-fuels/power-to-liquids) and how the concept of “green premium” enabled a three-way collaboration between Microsoft, Alaska Airlines, and Twelve.
How the partnership with IAG and the Chooose removed barriers for hundreds of Microsoft suppliers to purchase SAF for the first time.
Why Microsoft’s approach balanced carbon removal procurement with SAF investment alongside demand management, treating these not as competing priorities but as complementary strategies.

Fiddler also shares her journey from corporate travel management to leading industry-defining collaborations with airlines and SAF producers, and discusses how she’ll now be scaling these lessons globally through her new role at the RSB.

If you LOVED this episode, you’ll also love the conversation we had with Etosha Cave, Co-founder & Chief Science Officer of Twelve, who shares how the carbon transformation company harnesses CO2 from industrial waste streams to produce e-fuels. Check it out here.

How the oneworld BEV Fund is accelerating next generation SAF technologies

Épisode 146

jeudi 30 octobre 2025 • Durée 46:11

In this episode, we speak with Matthew Ridley, Director of Sustainability and Innovation at the oneworld Alliance, who shares the story behind the groundbreaking $150 million Sustainable Aviation Fuel (SAF) fund launched in partnership with the alliance’s member airlines and Breakthrough Energy Ventures (BEV).

Ridley discusses:

The alliance investment advantage: How pooling resources across oneworld members creates access to world-class venture capital expertise, superior deal flow, more diverse portfolios, and geographical networks.
Breakthrough Energy’s unprecedented value: Why partnering with BEV provides access to talent airlines struggle to attract, plus synergies with investments in nuclear fusion, energy transmission, and geologic hydrogen.
Next-generation focus vs. current needs: How the oneworld BEV fund targets technologies that can take aviation beyond 5-10% SAF adoption to truly change the trajectory of decarbonisation, complementing existing investments.
Breaking the alliance mould: How oneworld moved beyond traditional codeshares and interlining to tackle “initiatives of scale”, and how they attracted Singapore Airlines to join despite not being a oneworld member.
Reframing aviation’s challenge: Why the problem isn’t aviation itself, but rather the emissions from jet fuel, the only aspect of flight that hasn’t changed since the Kitty Hawk.

Ridley also shares insights from his seven years building IAG’s Hangar 51, where he led first-mover investments in ZeroAvia and LanzaJet, and explains why SAF isn’t a transition fuel but rather a permanent solution once emissions are addressed.

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

Épisode 48

jeudi 24 août 2023 • Durée 57:04

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.
