​Sustainable aviation fuel is a type of fuel that can be used by aircrafts, without causing harmful emissions or depleting natural resources. Sustainable aviation fuel can be made from renewable sources, such as biomass, waste, algae, or synthetic gas. Sustainable aviation fuel can reduce the greenhouse gas emissions and air pollution caused by aviation, as well as increase the energy security and diversity of the aviation industry. Sustainable aviation fuel is a key solution to address the environmental and social challenges of aviation, and to make it more compatible with the global goals of sustainability.
