Sustainable Aviation Fuel (SAF) is often described as “too expensive.” But what really drives this perception? In our upcoming webinar, The Cost of Compliance, we will unpack the true cost elements behind SAF and explore how greater clarity can shape investor confidence, airline appetite, and financing conditions.
Moderated by Andrew Doyle (Cirium), the expert round will feature a dynamic exchange of views from across the aviation value chain. Speakers include Dana Shoukroun(Invest Through Flying), Nikhil Sachdeva (Roland Berger), Dorottya Durucsko (Wizz Air), and Gregoire Le Comte (European Commission, DG MOVE).
Topics include:
Breaking down the “SAF premium”: what it is, how it impacts airlines, and the degree of transparency or negotiability in supplier pricing.
Mechanisms to narrow the price gap – from long-term offtakes and pooling to subsidies and market incentives.
The role of transparency in improving bankability, financing terms, and long-term contracting.
How EU SAF allowances can support offtakers, including eligibility criteria and procedures for allocation and pay-out.
Join us for a deep dive into the economics of SAF and what they mean for airlines, suppliers, and financiers navigating the path to compliance. Registration opens soon!

From transition to delivery: Lahiru Ranasinghe on steering easyJet’s decarbonization effort
impact sat down with Lahiru Ranasinghe, easyJet’s recently-promoted Director of Sustainability, who shared how the airline is shifting gear — from long-term planning to delivering tangible progress on its path toward Net Zero. Having led the development of easyJet’s Net Zero strategy, Lahiru now oversees delivery across all sustainability fronts — from flight operations and engineering to ground activities. The airlines’ aim is to build internal capabilities to progressively reduce its’ environmental impact.
🌍 With aircraft delivery delays still impacting the sector, easyJet continues to prioritize fuel-saving operational efficiencies across Europe, one of the world’s most complex airspace environments. But there’s a limit to what airlines can do alone — airspace modernization across Europe is essential to unlock 10% emissions reductions industry-wide.
🚀 Scaling SAF and Supporting Innovation easyJet is actively meeting SAF mandates across its 30+ European bases, while also pushing for progress on eSAF policy as part of Project SkyPower. Long-term, the airline sees hydrogen as the only viable route to truly zero-carbon flight for its short-haul network — and is backing its development accordingly.
📉 Tracking emissions reduction The airline uses emissions intensity (CO2 per RTK) as its main progress metric. easyJet also closely monitors peers’ sustainability efforts to benchmark its own, but sees the journey to Net Zero as an industry-wide challenge that requires collective progress.
💬 “We cannot afford to be one of the few heavy emitters left in the world when we get into the 2040s and 2050s,” Lahiru notes. “There’s a lot at stake.”

During our recent IMPACT on sustainable aviation members call, Arnaud Namer, CEO and co-founder of ATOBA energy, shared his vision for solving the financial roadblocks in sustainable aviation fuel production.
With 25 years in aerospace and decarbonization, Arnaud brings deep experience to a complex challenge: Producers need financial certainty and airlines need affordable, competitive SAF. But with over 250 SAF projects proposed, a patchy and/or unstable policy landscape, few players can afford the due diligence or risk exposure required.
Enter Atoba Energy’s aggregation model:
Pools long-term offtake from multiple producers & airlines
Spreads risk across feedstocks, technologies, and timeframes
Offers indexed pricing (via General Index) for transparency and thus addresses airlines‘ concerns about competitive disadvantage
Helps secure ROI for producers, and competitive SAF for airlines
Aggregation isn’t just a financial tool — it’s a strategic lever for scaling SAF and managing transition risks across the value chain.
Thanks to Arnaud for unpacking ATOBA‘s approach — and showing how financial structuring can accelerate aviation’s path to Net Zero.
Can commercial aviation realistically develop and adopt the new technologies crucial to achieving Net Zero by 2050? This questions was addressed during impact’s first webinar on June 12, hosted by ISTAT as one of its Learning Lab sessions.
Aviation stands at a critical juncture in its decarbonization journey. The path to Net Zero will be shaped by technology — but what’s truly possible over the next 15 years? The expert round, moderated by Michael Halaby (MUFG), featured Jonathon Counsell (IAG), Sandrine Lacorre (CFM International), Dan Rutherford (ICCT) and Julian Renz (ZeroAvia) for a lively discussion on topics including
🔍 What’s a realistic trajectory for aviation’s technology shift? 🛩️ How big a step can Airbus and Boeing take by 2035? 🔥 Can gas-turbine innovation still surprise us? 🚀 Is a new tech player capable of launching a mainline airliner by the late 2030s? 📉 What are the risks of inaction vs early-mover advantage? 🐉 Could China emerge as a disruptive force in global aviation?
How can lessors align SAF with their leasing interests? SAF is essential to aviation’s path to decarbonisation – but supply isn’t scaling fast enough. Lessors can help change that.
In a recent interview, Eduardo Mariz, Senior Analyst & Sustainability Lead at Ishka, and Dr. Ulrike Ziegler, Managing Director of impact, spoke to Dr. Amy Ruddock, SVP of Sustainable Aviation at Willis Lease Finance Corporation (WLFC) about how lessors can play a bigger role in making SAF commercially viable. WLFC is leading by example, currently investing in a 14,000-ton-per-year SAF facility in the UK through Willis Sustainable Fuels.
The company’s first SAF production facility will be located near Teesside International Airport, where the UK plans to build its first SAF handling waterside terminal. WLFC’s facility will use Carbonshift FlexFeed – an innovative technology that is ultimately designed to produce power-to-liquid (PtL) fuel but can flexibly use bio-methane or green hydrogen as its input.
Among the key reasons for WLFC’s decision to invest in SAF production in the UK are: 1. Long-Term Industry Commitment: WLFC sees sustainable aviation as critical to its long-term success and competitiveness 2. Favourable Regulatory Environment: UK policies, including SAF mandates, revenue certainty mechanisms, and carbon reduction targets, provide market clarity and support investment
Why should lessors engage in SAF? 🔸 Helping de-risk SAF financing – Integrating SAF certificates into lease contracts could unlock bankable offtake agreements, a major hurdle for SAF developers 🔸 Gaining a competitive edge – Lessors acting as SAF offtakers can offer airlines better access, particularly in regions with limited supply 🔸 Adapting to an evolving aviation landscape – Expanding their role beyond leasing allows lessors to align with industry sustainability demands and regulatory shifts
What’s in it for lessors? ✅ Future-proof their business as sustainability regulations tighten ✅ A growing multi-billion-dollar market with rising demand ✅ Stronger airline partnerships by supporting decarbonisation goals
As Amy highlights: “Any investment in lowering carbon is a commercial investment too – it’s an investment in the future of the industry.”
