Aviation faces a steep climb toward decarbonization. While sustainable aviation fuels (SAF) offer a path forward, high costs and limited supply make them difficult to scale. Hydrogen remains a long-term goal, but the technical challenges of cryogenic storage keep it decades away from commercial use. Beyond fuel, the industry struggles with the environmental trade-offs of speed. Supersonic travel increases fuel consumption and releases emissions higher in the atmosphere, complicating climate goals while the sector seeks a viable, zero-carbon alternative for long-haul flights.
