Supply chain ' lacks market coordination ' Hader and Bauer say that there is “ a lack of market coordination along the supply chain ”, and that this is preventing progress on sustainable aviation technologies .
To improve things , they say , original equipment manufacturers ( OEMs ) “ need to clearly communicate technology roadmaps with suppliers ”, adding that governments “ must also commit to increased funding and clearer policies ”.
The Roland Berger consultants say that , of all aviation industry suppliers , systems suppliers are making the most progress , because “ they are concentrating on electrification of onboard systems and other weightor energy-saving solutions to

Bauer adds that aerostructure and interiors suppliers are also focusing on reducing weight , as well as improving recycling loops for materials . Yet it is propulsion suppliers that have the biggest impact on aircraft sustainability .
The majority , says Hader , “ are currently focusing much of their efforts on sustainable aviation fuels ( SAF ) in combination with more advanced conventional engines ”.
Three quarters of respondents to Roland Berger survey say these two things are their first or second priorities , while a quarter say hybrid propulsion is a main priority and just 16 % say hydrogen . “ Electric propulsion , which is mostly
