Climate protection
Aviation affects the climate far beyond CO₂ emissions – primarily through so-called non-CO₂ effects such as water vapor, nitrogen oxides, and contrails. The decarbonization and defossilization of aviation is therefore a complex challenge and requires holistic solutions. The focus is not only on technical solutions, such as sustainable aviation fuels (SAF), but also on political framework conditions and market-based approaches. Strategies and roadmaps at the national, European, and global levels are intended to pave the way for climate-neutral aviation by 2050.
Sustainable Aviation Fuels
Sustainable aviation fuels (SAFs) play a central role in the transformation of aviation towards more climate-friendly aviation. They enable significant CO₂ savings compared to fossil kerosene. At the same time, SAFs differ significantly in terms of their environmental impact, economic scalability, and technical maturity. This article highlights the most important production routes, regulatory requirements, sustainability assessments, and market developments—and shows how SAFs can contribute to climate-neutral aviation by 2050.
Framework conditions
Air transport is shaped by a variety of regulatory frameworks. These include SAF mandates, investment programs, regulatory requirements, and market-based systems such as the EU emissions trading system or the global compensation program CORSIA. The measures range from international regulations and European directives such as ReFuelEU Aviation to national measures such as the German Federal Climate Protection Act or aviation taxes, all of which play a role in the transformation of air transport.
