Alternative aviation fuels are in the starting blocks: Today, there are two reliable production processes and half a dozen pathways that will be certified in the foreseeable future. Their technical safety has been proven with more than 1,500 successful test flights internationally. The success of this is important because without an increase in the use of alternative aviation fuels, ambitious national and international climate protection goals cannot be achieved. The German Federal Government is correct in setting sight on using alternative fuels for aviation, as is documented in its Mobility and Fuel Strategy (Mobilitäts- und Kraftstoffstrategie, MKS),  in order to reduce greenhouse gas emissions in the entire transport sector by 40 per cent by 2020, in comparison to 1990.

Nevertheless, biofuels are more expensive and therefore not yet able to compete with fossil kerosene. In order to change this and to enable alternative aviation fuel to be broadly deployed in the next few years, all stakeholders working in the aviation industry and the political sphere must co-operate. It is necessary to agree on standards and objectives and to create a reliable framework of conditions.

Biofuels must also be intensively developed further in order to

  • obtain the highest possible yield in the smallest possible area;
  • promote the production of food crops and energy crops to avoid any competition;
  • increase the use of waste and residual materials, as well as newly developed raw material pathways such as algae, which do not require the use of agricultural land.
