Effective December 9, 2025, Dr Paul Bloom has been appointed President of Gevo and will succeed Gruber as CEO on the latter’s retirement. Bloom joined Gevo in 2021, playing a role in advancing the company’s technology and executing commercial strategy.
The SASHA Coalition has released a policy briefing that outlines the environmental and economic benefits of zero carbon emission technology, the challenges to achieving commercialisation and the policies needed to overcome them. It recommends policymakers introduce a mandate for all intra-EU flights of less than 400km to be zero carbon emission by 2040; ensure that green hydrogen is available for aviation; establish regional testbeds to demonstrate zero carbon emission aviation; and extend support for research and development. Coalition members include ZeroAvia, Hybrid Air Vehicles and Ecojet.
Private aviation company JETEX has become the latest strategic investor in Azzera’s digital carbon management platform. The aviation sustainability provider says the new investment will position the technology platform to continue evolving functionality, grow its international footprint and deliver new client-facing offsetting tools to its users’ customers. The company also confirms JETEX will act as a lead partner for a new tool, Azzera SAF Productivity Operations and Delivery (SAF POD), which will be accessible via the CELESTE platform. Under the agreement, JETEX will also work with Azzera to procure and manage SAF for its international fleet beginning in early 2026. The investment concludes Azzera’s $800,000 capital raise.
According to projections by aviation market intelligence company IBA, North America is currently the only global region on track to meet ICAO’s 2030 goal of a 5% reduction in CO2 emissions from international aviation through the use of SAF and other clean energies. All other regions, including Europe, Asia-Pacific, Latin America, Africa and the Middle East are forecast to fall short of the goal unless significant additional SAF capacity is developed, says IBA. The calculations were based by combining ICAO’s latest SAF production capacity data with IBA’s global fuel demand forecasts. Globally, says IBA, SAF facilities that are operational or under construction currently equate to around 4.5% of global jet fuel supply in 2025.
Maryam Al Balooshi, Senior Manager of the Environmental Affairs Office at the UAE’s General Civil Aviation Authority has been elected Chair of ICAO’s Committee on Aviation Environmental Protection (CAEP). She is the first from the Middle East to hold this position, which encompasses international responsibilities related to shaping the future of the aviation sector in reducing its environmental impacts. CAEP is a technical advisory body reporting to the governing ICAO Council and consists of 11 working groups and around 1,200 experts that are focused on key areas including aircraft noise, engine emissions, climate change, SAF and the development of environmental management tools.
XCF Global has completed initial site work at New Rise Reno 2 in Nevada, the company’s second SAF production facility, and with engineering, design and project planning underway, construction is planned to begin in 2026. Since inception, $350 million has been invested in New Rise Reno. New Rise Reno 2 represents the next phase of the company’s growth strategy, with an expected $300 million investment enabling XCF to double SAF production capacity to 80 million gallons annually. In November, XCF signed a MoU with global energy and commodities group BGN to jointly develop global distribution, marketing and offtake frameworks across Europe, the Middle East and other strategic markets.
France-based Beyond Aero, which is aiming to build the first electric business aircraft powered by hydrogen propulsion, has completed its feasibility study for a new aircraft manufacturing site. The facility would support production of 60 aircraft per year and create 225 jobs. The company’s BYA-1 six-passenger aircraft, capable of flying 1,500km, recently reached Technology Readiness Level 6 (TRL6) for its full-scale hydrogen-electric propulsion system and has completed France’s first manned, fully hydrogen-electric flight. Beyond Aero says it has secured over $50 million in funding and $1 billion in Letters of Intent.
UK leisure airline Jet2 has been awarded an A- rating by CDP in its latest climate disclosure assessment, widely regarded as the global benchmark for environmental reporting, with scores recognised by investors, regulators, governments and customers. Jet2 says the improved rating from B to A- demonstrates its leadership and best practice when it comes to decarbonising its operations, as well as setting science-based targets and developing robust plans to reduce emissions in the future. The carrier plans to reduce its carbon emissions per RPK by 35% in 2035 compared to 2019 and is introducing new, more fuel-efficient Airbus A321neo aircraft into its fleet, with 155 aircraft on order.
AfriSAF and the African Airlines Association (AFRAA) have signed a MoU that establishes a framework for collaboration to accelerate the deployment and production of sustainable aviation fuel across Africa. Under the MoU, the two parties will work together to support SAF adoption, develop bankable SAF production projects, strengthen feedstock supply chains and promote policies that enhance aviation safety, security, efficiency and environmental sustainability. They will collaborate on five joint initiatives: advocacy and policy support; capacity building and training; SAF project development; resource mobilisation; and feedstock mapping and sustainability. AfriSAF, says CEO Kwame Bekoe, is a digital marketplace, traceability platform and SAF project developer focused on aggregating and upcycling agricultural residues and other sustainable feedstocks across Africa.
The Lufthansa Group is further expanding its fuel efficiency programme OPS Sustainability. Since 2022, over 90 projects have helped save approximately 54,000 tonnes of jet fuel, thereby avoiding around 170,000 tonnes of CO2. The company has set itself the target of avoiding around 50,000 additional tonnes of CO2 annually across the group by the end of 2028, among other things by using new digital tools and data-based decision models. This corresponds to an additional fuel saving of over 15,200 tonnes. The measures include, for example, the use of digital applications that will enable even more precise decisions to be made in future about the amount of fuel required for a flight, optimised taxiing and approach procedures, more demand-oriented water loading and more precise flight planning.

ICAO releases first-ever growth factor for airlines’ CORSIA offsetting requirements
18 December 2025
ICAO has confirmed governments participating in its CORSIA scheme will shortly be informing airlines of their first-ever carbon offsetting requirements under the international agreement. The emissions data collected or estimated from 138 member states was used to calculate the global growth of emissions from international civil aviation for 2024, the start year of the voluntary First Phase of the scheme, against a baseline of 85% of total 2019 CO2 emissions. By applying the Sector’s Growth Factor for 2024, which has just been released, to emissions data submitted by each airline, governments can calculate the amount of CO2 each airline needs to offset through the purchase of CORSIA Eligible Emission Units (EEUs). In other CORSIA news, following earlier recognition by ICAO under the Pilot and First Phase, Gold Standard and Verra have been approved to supply credits for its Second Phase (2027-2029). ICAO has also approved Isometric to issue its verified carbon removal credits to airlines under CORSIA.

Swiss advanced SAF technology startups Metafuels and Synhelion reach project milestones
18 December 2025
Two Swiss cleantech startups, Metafuels and Synhelion, have announced key milestones in plans to develop their advanced technology pathways to commercialise new-generation sustainable aviation fuel production in Europe. Zurich-based Metafuels has awarded a contract to McDermott for front-end engineering and design (FEED) of its Turbe project, a first-of-a-kind eSAF facility to be built at the Evos terminal in the Port of Rotterdam. The plant is expected to be the first commercial deployment of Metafuels’ proprietary methanol-to-jet technology, aerobrew. Also based in Zurich, Synhelion has signed a long-term offtake agreement with Swiss International Air Lines (SWISS) in which the airline will purchase at least 200 tonnes of solar jet fuel annually from 2027. In July, Synhelion delivered its first barrel of syncrude from its DAWN production facility to a refinery in Northern Germany, where it was processed into Jet-A1 aviation fuel and fed into SWISS’s flight operations infrastructure via the fuel supply system at Hamburg Airport.

PtX fuels have significant Asia-Pacific potential but face many barriers, finds report
16 December 2025
A new study has highlighted significant potential for Power-to-Liquids (PtL) and Power-and-Biomass-to-Liquids (PBtL) aviation fuels in the Asia-Pacific region. However, fragmented national strategies, immature technologies and insufficient planning for renewable electricity supply are among the key barriers to progress. Produced by the Roundtable on Sustainable Biomaterials (RSB) and FutureScaleX Insights, in consultation with a broad range of industry stakeholders, the study is billed as the first integrated assessment of the region’s preparedness to develop these next-generation fuels into “a credible pillar” of low-carbon aviation. Asia-Pacific, the world’s largest consolidated air transport market, is a region of high potential but uneven readiness, says the report, with clear gaps in policy coherence, stakeholder capacity and the investment frameworks needed for large-scale production and deployment. It argues progress is achievable if countries across the region combined their respective strengths instead of acting independently.

Airfreight giants DHL Express and FedEx announce big US SAF deals
16 December 2025
Two of the world’s largest airfreight companies, DHL Express and FedEx, have announced fresh deals to buy sustainable aviation fuel in the US, advancing separate commitments that by 2030, SAF will comprise at least 30% of their jet fuel. In the biggest transaction, DHL will procure 83 million gallons (240,000 tonnes) over three years from US energy major Phillips 66, initially for delivery to Los Angeles International Airport and later to other Californian gateways including San Francisco International Airport. Meanwhile, Memphis-based FedEx has started using SAF at Chicago O’Hare International and Miami International airports, more than doubling its US uptake. In Chicago, it has procured 1 million gallons of neat SAF from Air bp, delivered as blended product, while in Miami it has signed with Associated Energy Group (AEG) for 3 million gallons of blended SAF. These two deals follow a 3 million-gallon SAF purchase at Los Angeles in May.

Asia-Pacific study reveals pessimistic outlook for SAF uptake by 2030 as Singapore details levy
15 December 2025
A new assessment of sustainable aviation fuel across the Asia-Pacific region highlights low expectations of usage by 2030 without urgent policy support, saying multiple countries have proposed and discussed SAF targets but few have firm targets or clear implementation mechanisms. The report, based on a comprehensive survey of mostly APAC-based stakeholders across the SAF sector, concluded with “a pessimistic outlook for SAF penetration by 2030 under the status quo,” and recommended fresh measures including acceptance of book-and-claim procurement programmes in SAF mandates and a switch from volumetric usage targets to carbon intensity-based targets to more accurately reflect the emissions of different types of new fuels. Meanwhile, Singapore has released details of its SAF levy that is to apply from October 2026.

Supply shortage means airlines have no chance of meeting a 10% SAF by 2030 target, says IATA chief
11 December 2025
Targets set by airlines to have a 10% mix of sustainable aviation fuel in their fuel consumption by 2030 will be impossible to achieve, believes Willie Walsh, Director General of industry body IATA. Following a year of SAF not being produced in the volumes expected, the pace of progress towards the industry’s net zero emissions by 2050 ambition was disappointing and worrying, he briefed journalists. While the net zero target was still possible and the airline industry remained committed, it was becoming more and more challenging and more expensive, he said. He was particularly critical of regulators imposing mandates on the use of SAF that was not available and “price gouging” jet fuel suppliers that passed on their mandate compliance fees to airline customers. IATA revealed SAF output is expected to reach 1.9 Mt in 2025, nearly double that in 2024, but growth is projected to slow to 2.4 Mt in 2026, making up 0.8% of total jet fuel consumption, up from 0.6%.

New Zealand initiatives announced on electric aircraft, hydrogen refuelling and carbon removals
8 December 2025
Air New Zealand has commenced testing of a battery-electric BETA Alia CX300 aircraft, ahead of commercial evaluation of cargo flights with a second aircraft in 2027. Together with a technical team from the manufacturer, US-based BETA Technologies, the airline will perform flights throughout the country, assessing the aircraft’s performance in various manoeuvres and conditions. It will also use the aircraft to evaluate ground infrastructure including electric charging equipment and handling services, as it explores options to help decarbonise its operations. In a parallel initiative, the airline has committed to buy 8,000 tonnes of internationally verified, New Zealand-sourced, nature-based carbon removals by 2030. And separately, New Zealand engineering group Fabrum and Australian hydrogen aircraft start-ups AMSL Aero and Stralis Aircraft are collaborating at Christchurch Airport to progress hydrogen-powered flight.

EU states to mobilise 500 million euro support for early-mover eSAF production startups
5 December 2025
The European Union has launched the eSAF Early Movers Coalition, which brings together member states that have committed to scaling up the production of synthetic aviation fuels (eSAF). Eight states have so far announced their participation – Austria, Finland, France, Germany, Luxembourg, Netherlands, Portugal and Spain – with the intention of mobilising at least €500 million ($580 million) for large-scale eSAF projects. The coalition members will seek to provide financial support for the organisation of double-sided auctions – a revenue certainty mechanism for eSAF producers – with the first auction planned for 2026. The initiative follows the recent release by the European Union of its Sustainable Transport Investment Plan (STIP), a set of measures to accelerate investment in the energy transition of the aviation and maritime sectors.
