The environmental impact of air travel is a growing concern due to the significant carbon dioxide emissions released at high altitudes, contributing to global warming. Despite the environmental challenges, flights continue to increase annually. To combat this, the aviation industry is focusing on greener alternatives. One significant solution is Sustainable Aviation Fuel (SAF), created from organic waste or by combining hydrogen with captured CO2, showing potential to reduce emissions by 65 percent. The first flight using 100 percent SAF was successfully completed by Virgin Atlantic, demonstrating its compatibility with current aviation infrastructure. Additionally, electric planes offer a promising future with zero emissions during flights, but are currently limited by battery technology. Hydrogen-powered planes, emitting only water vapor, are expected to be operational by 2035, requiring changes in aircraft design and ground infrastructure. While green aviation is still evolving, initiatives like analyzing flight data for greener options and promoting more efficient travel practices are underway to mitigate emissions. The future of aviation is aimed at achieving net-zero emissions, with innovations in Sustainable Aviation Fuel, electric aircraft, and hydrogen-powered planes paving the way for a more sustainable air travel industry.
