As the demand for flights increases, the global aviation industry faces the challenge of transforming to become more sustainable. The article suggests six pathways to set aviation on a greener future course. Decarbonizing aviation is essential due to its significant environmental impact, with global carbon dioxide emissions from aviation surpassing a gigaton in 2019. With demand expected to double or triple by 2050, sustainable solutions are imperative to mitigate the industry's carbon footprint. The pathways proposed include adopting sustainable aviation fuels, advancing hydrogen and electric propulsion, optimizing air traffic management, and implementing policies that incentivize sustainable practices. Sustainable aviation fuels, derived from renewable feedstocks, can cut carbon dioxide emissions by up to 80% compared to conventional fuels. Zero-emission technologies like hydrogen-powered aircraft and electric propulsion are crucial for long-term decarbonization. Improving efficiency in flight operations and ground activities through various measures like continuous descent operations and performance-based navigation can reduce fuel consumption and emissions. Policy frameworks focusing on carbon pricing and stringent criteria are essential for achieving net-zero emissions, with global initiatives targeting carbon neutrality by 2050. Additionally, addressing alternative transports such as private aviation, a growing contributor to emissions, is vital for a sustainable aviation future.
