Abstract World over the air travel is the fastest growing source of greenhouse gases leading towards global climate change. Estimates show that each long distance flight of a 747 adds approximately 400 tons of CO2 to the atmosphere. Like elsewhere in Libya too with the expected threefold increase in air travel over the next 30 years, the reliability and environmental impact of aviation are becoming critical issues for the future of flight in the country. This paper is designed to present greener sky initiative indicating how Civil Aviation Technical College based at Sbia Libya in its march towards sustainable aviation is focusing on critical technologies like: (a) Integrated modeling of vehicles, atmospheric impact, and noise (b) optimization of new aircraft concepts and operations including environmental impact and (c) distributed, adaptive sensing and control. It treats sustainability is the way forward for aviation to be safe, efficient, affordable, responsive and healthy. Current research to replace conventional oil using numerous alternatives like hydrogen fuel in airplanes shows that the new technology offers not only reduced emissions but also offer advantages like lower takeoff weight, better long haul fuel efficiency and improved engine design opportunities. In addition it is found that H2 works well with fuel cells. Interesting findings to achieve aviation sustainability demonstrate that it is possible to meet the challenges of 4× larger fuel tanks, higher drag, higher empty weight, H2 production issues, new infrastructure, affordable cost, high technical risk, passenger acceptance and environmental effects. All it needs is an adequate attention in policy making, hydrogen infrastructure development, environmental concerns, regulatory actions, standards development, safety, storage, commercialization, through capacity development, education, and training.
