PtX Lab Talk sheds light on the effects of the new air traffic tax

Authorities are fueling aircraft before flying

Experts discussed whether the recently increased aviation tax can reduce emissions and what additional measures are needed for green aviation.

The new federal budget is having an impact on many sectors and projects. The aviation industry, which is urgently reliant on the development and production of sustainable aviation fuels, is also feeling the financial pinch. The market ramp-up of sustainable, synthetic fuels, so-called Sustainable Aviation Fuels (SAF), appears to be slowing down. The question arises as to how the availability of sustainable aviation fuels can be improved.

Can emissions in this sector be reduced by means of a higher aviation tax? What about the market ramp-up of power-to-liquid (PtL) paraffin? And what additional measures are needed? We talked about this on 29 February 2024 in our PtX Lab Talk on the topic of "The new aviation levy: Is the steering sufficient?". Over 70 interested people took part in the ninth edition of our digital event series.

All speakers agreed on one point: the cuts in the promotion of synthetic fuels based on renewable energies must be compensated in order not to slow down their market ramp-up before the start and to fulfil the SAF blending quotas. Reliable framework conditions are the foundation for this. The aviation levy, guarantees and long-term purchase agreements have been identified as suitable financing instruments. SAFs are in demand. However, there is a lack of production capacities and the necessary investment decisions. This could be remedied by establishing a capacity market for PtL kerosin.
