SkyNRG says […]
  • Two major industrial collaborations have been established in Japan to progress ambitions for large-scale production of sustainable aviation fuels (SAF) in the country, writes Tony Harrington. In the first project, sponsored by Japan’s Ministry of the Environment, six prominent corporations have joined forces to demonstrate the extraction of carbon dioxide from industrial exhaust gases, and its conversion into SAF as part of a broader plan to also drive regional revitalisation […]
  • Acknowledging the importance of sustainability as the sector rebuilds from the Covid-19 pandemic, airline industry body IATA is to add environmental sustainability to its training curriculum. It says a recent survey of 800 industry training professionals identified sustainability as a top training need and has launched the new programme with the University of Geneva (UNIGE). With new Director General Willie Walsh now in place, IATA has elevated the role of […]
  • In March the Greener by Design Group of the Royal Aeronautical Society, together with the Institute of Atmospheric Physics at the German aerospace research organisation DLR, jointly organised a virtual conference entitled ‘Mitigating the climate impact of non-CO2 – Aviation’s low-hanging fruit’. The conference provoked a Commentary article in GreenAir last month from Professors Keith Shine and David Lee arguing that “low-hanging fruit may be superficially attractive, but only if […]
  • New Zealand’s aviation sector has consistently shown a pioneering commitment to sustainability, and is now embracing a move towards electric propulsion, reports Tony Harrington. Regional airline Sounds Air has just announced it will acquire three Heart Aerospace ES-19 electric airliners, emerging as the first Asia-Pacific operator to choose the Swedish all-new aircraft. The carrier’s switch to electric aircraft comes at a time of significant national focus on sustainability, as the […]
  • As part of its ‘Jet Zero’ strategy to ensure the aviation sector meets the national target of net zero emissions by 2050, the UK government is considering whether to mandate the provision of standard, reliable and accurate environmental information to encourage travellers at the time of booking their flights to choose the greenest option. Such information, says the Department for Transport (DfT) in a consultation launched last month, could help […]
  • Embraer has announced a package of sustainability initiatives, headlined by a commitment to achieve carbon neutral operations by 2040, and to actively develop electrification, hybrid propulsion, sustainable aviation fuels and “other innovative energy alternatives” to reach net zero emissions by 2050, reports Tony Harrington. The Brazilian manufacturer of regional and corporate jets has pledged to develop products, services and disruptive sustainable technologies, including a zero-emission e-VTOL aircraft by 2026, to […]
  • Cargo operator DHL Express and Brazilian airline Azul have become the latest carriers to join the early pacesetters in making commitments to take delivery of all-electric aircraft in the coming years, reports Mark Pilling.

  • Two UK sustainable aviation fuel (SAF) projects in the UK have been announced that involve British Airways, one to investigate a commercial facility that would produce more than 100 million litres per year of jet fuel made from atmospheric CO2 and the other to recycle carbon from UK wood waste and turn it into SAF. Partners on the projects include US company LanzaTech and its offshoot LanzaJet. Project AtmosFUEL is […]
  • Following closely behind the release of the European Commission’s ReFuelEU Aviation sustainable aviation fuel (SAF) blending mandate proposal, the UK’s Department for Transport (DfT) has opened an eight-week consultation on its own proposal for a UK SAF mandate. In common with the EU, the UK mandate would likely start in 2025 and place obligations on jet fuel suppliers but otherwise the two schemes differ in how the mandate should be […]
  • Eight proposed sustainable aviation fuel (SAF) projects have been shortlisted by the UK’s Department for Transport (DfT) to share up to £15 million ($20m) in grant funding to support early-stage development of large-scale SAF production plants in the UK. All selected projects have the potential to reduce emissions by more than 70% on a lifecycle basis when used in place of conventional fossil jet fuel, said the DfT. The plants […]
  • A substantial component of aviation’s climate impact is presently caused by non-CO2 effects, most notably contrail formation; if weather conditions are right, these can evolve into so-called contrail cirrus. A recent assessment of the drivers of climate change due to aviation estimated the present-day climate effect of contrail cirrus was 65-70% greater than that of CO2, albeit with a significantly greater uncertainty. Clearly, if that contribution could be mitigated, it […]
  • The UK government has opened a public consultation on an action plan for the UK aviation sector to reach its net zero emissions by 2050 target, which it calls ‘Jet Zero’. Its draft strategy relies on a combination of five different measures: making airspace system efficiencies, building a sustainable aviation fuels (SAF) industry, developing zero emission aircraft technology, using cost-effective market-based measures and working to influence the behaviour of air […]
