  • Why Mission Possible Partnership believes cross-sector collaboration can accelerate aviation’s path to net-zero
    In this episode, we speak with Dick Benschop, Chair of the Board at Mission Possible Partnership (MPP), an alliance of climate leaders focused on supercharging efforts to decarbonise hard-to-abate sectors.Benschop discusses:The challenge of decarbonising aviation amid rapid growth with focus on both efficiency and sustainable fuels.How blending mandates can break the “chicken and egg” problem between SAF suppliers and airlines, with Europe’s 2% mandate in 2025 serving as a catalyst for market development. Currently, there are 40 SAF plants in operation and 10 with Final Investment Decision (FID), representing about 50% of 2030 capacity needs, with 143 more plants announced*.The importance of smart environmental constraints over simple capacity caps, advocating for declining noise and CO2 emission limits that allow airlines to “earn their place” through innovation.The potential for electric and hydrogen aircraft to serve up to one-third of aviation energy demand by 2050, with electric planes operational by 2030 and hydrogen aircraft following by 2035.How breaking down silos between sectors can accelerate decarbonisation, using lessons from aviation’s blending mandates to inform solutions in other industries like green fertiliser production.Benschop emphasises that achieving net-zero aviation requires looking beyond individual sectors to system-wide solutions, highlighting the need for coordinated action across industry, government and consumers. *Note: The podcast mentions different figures for the number of SAF plants needed. The numbers cited above reflect MPP’s latest analysis, which shows that actual plants are larger than initially assumed, meaning fewer total plants are needed to meet 2030 capacity targets. If you LOVED this episode, you’ll also love the conversation we had with Andrew Chen, Principal for Aviation Decarbonisation at RMI, who shares the non-profit’s multi-faceted approach to aviation decarbonisation.

  • Why ClimateWorks Foundation believes strategic philanthropy is essential for the net zero transition
    In this episode, we speak with Anna Stratton, Associate Director, Aviation at ClimateWorks Foundation, a global platform for philanthropy that has granted over $2 billion to climate solutions across 50 countries. Stratton shares insights into how philanthropic funding can drive aviation’s transition to net zero while ensuring emerging markets aren’t left behind. She discusses:The crucial role of philanthropy in advancing sustainable aviation solutions through research, analysis, and policy developmentWhy Europe’s ReFuelEU policy sets a strong standard for sustainable aviation fuel (SAF) mandate with its long-term outlook to 2050, specific e-fuel requirements, and robust sustainability safeguardsThe potential of hydrogen for short and medium-haul flights, and the innovative approach of collaborating with shipping sector for infrastructure solutionsWhy contrail mitigation represents an exciting near-term opportunity for emissions reduction, and the importance of monitoring and verificationThe need to reimagine aviation growth, particularly focusing on high-flying groups like corporate travelersStratton emphasises that while industry focuses heavily on SAF, a comprehensive vision for net-zero aviation must include multiple solutions. She also outlines how philanthropy can strategically support civil society in driving aviation’s sustainable transformation, highlighting the need for both technological innovation and behavioural change.Please note: This interview was recorded in September 2024. ClimateWorks has since updated its 2024 transportation grants, with $5.5M allocated to aviation, $72.3M to road transportation, and $13.3M to maritime shipping, bringing the total to $91.1M. The updated data is available on their website.If you LOVED this episode, you’ll also love the conversation we had with  Sally Davey, CEO of Travalyst, who shares insights about transforming the travel industry through collaborative data initiatives.

  • How Heathrow’s SAF incentive aims to tackle critical barriers to adoption
    In this episode, we speak with Matthew Gorman, Director of Carbon Strategy and Sustainability at Heathrow Airport. With 16 years at the helm of Heathrow's sustainability initiatives, Gorman shares how one of the world’s busiest airports is tackling aviation’s climate impact while maintaining its crucial role in global connectivity.Gorman discusses:Heathrow’s Sustainable Aviation Fuel (SAF) incentive scheme, which creates a funding pool through landing charges to help airlines bridge the cost gap of SAF adoption. Starting at 0.5% in 2022, the target will reach 3% by next year, with approximately 20 airlines participating.The breakdown of Heathrow’s carbon footprint, highlighting that nearly 95% comes from aircraft operations, around 5% from ground activities such as surface access and the supply chain, and just 0.1% from direct operations (Scope 1).The future of hydrogen aviation, with expectations of first hydrogen-powered services in the early 2030s starting with turboprops, and how Heathrow is preparing infrastructure through research partnerships and dedicated testing facilities.Their innovative approach to NOx emissions reduction, targeting 18% reduction in airside operations and 60% in non-aircraft operations by 2030, driven by Heathrow’s proximity to London.Throughout the conversation, Gorman emphasises the critical balance between maintaining aviation’s connectivity benefits while achieving net zero, and how airports can lead the sector’s sustainability transition through influence and advocacy despite controlling only a small fraction of total emissions.If you LOVED this episode, you’ll also love the conversation we had with Christina Cassotis, CEO of Pittsburgh International Airport, who shares her ambitious vision for transforming the airport into a sustainable aviation hub.
