Best of 2025: The ideas that defined aviation’s climate debate
Sustainability In The Air
Intro
Shashank Nigam introduces the special year-end episode and frames aviation's real inflection point in 2025.
In this special year-end episode, we explore conversations with industry leaders revealing where sustainable aviation truly stands in 2025.
- Matt Gorman, Director of Carbon Strategy at Heathrow Airport, reveals airports control just 0.1% of their carbon footprint directly but use landing charges to incentivise SAF adoption.
- Tamara Vrooman, CEO of Vancouver Airport, explains moving their net-zero target forward to 2030 by leveraging control of central infrastructure.
- Lena Wennberg, Chief Sustainable Development Officer, and Therese Forsström, Head of Environmental Department at Swedavia, explain achieving fossil-free operations in 2020 and how they are looking to support fossil-free domestic flights in Sweden by 2030.
- Aaron Robinson, Vice President of SAF at International Airlines Group, identifies airlines’ reluctance to adopt SAF as a cultural problem rooted in safety-first mindsets that resist innovation.
- Matthew Ridley, Director of Sustainability at The oneworld Alliance, discusses their $150 million fund with Breakthrough Energy Ventures for next-generation SAF.
- Trevor Best, CEO of Syzygy Plasmonics, details their photocatalytic technology converting biogas into SAF at smaller scales, targeting jet fuel parity.
- Tim Boeltken of INERATEC explains their modular e-fuel technology deployable wherever green hydrogen is produced.
- Marc Allen, CEO of Electra, describes how electric aircraft will succeed by enabling new capabilities like 150-foot takeoffs rather than competing with jet fuel.
- Billy Thalheimer of Regent introduces Seagliders – wing-in-ground effect vehicles offering new transportation for coastal routes.
- Jolanda Stevens, Program Manager for Zero Emission Aviation at KLM, emphasises airlines’ responsibility in enabling hydrogen and electric aircraft.
- Luke Farajallah, CEO of Loganair, discusses how their mandatory £1 carbon levy receives almost no passenger complaints.
