Sustainable aviation fuels (SAFs) are alternative fuels designed to reduce the environmental impact of air travel. They are produced from renewable resources, such as plant materials, waste oils, and other sustainable feedstocks. SAFs can significantly lower greenhouse gas emissions compared to traditional jet fuels, making them a key component in efforts to combat climate change. These fuels can be used in existing aircraft engines and infrastructure without requiring major modifications. By blending SAFs with conventional jet fuel, airlines can gradually transition to more sustainable practices while maintaining safety and performance standards. This innovation supports the aviation industry's goal of achieving net-zero emissions by 2050.
