Advancing Sustainable Aviation Evaluating the Role of Alternative Fuels and Green Technologies in Reducing Carbon Emissions

Abstract

The aviation industry is a significant contributor to global greenhouse gas emissions, necessitating urgent strategies for carbon reduction to meet international climate targets. Sustainable aviation, driven by alternative fuels and green technologies, has emerged as a pivotal solution to mitigating environmental impacts. This study evaluates the potential of alternative fuels, such as sustainable aviation fuel (SAF), biofuels, and hydrogen-based fuels, in reducing carbon emissions while maintaining operational efficiency. It also examines advancements in green technologies, including electric and hybrid-electric propulsion systems, aerodynamic innovations, and lightweight composite materials, that collectively enhance fuel efficiency and minimize emissions. By analyzing recent developments and case studies from leading aviation companies, the study highlights both the opportunities and challenges associated with implementing these solutions on a large scale. The key barriers such as high production costs, infrastructure limitations, and regulatory constraints are critically assessed. Findings suggest that a combination of alternative fuels and green technologies can significantly reduce aviation’s carbon footprint if supported by strong policy measures and industry-wide collaboration. This research underscores the need for continued investment, cross-sector partnerships, and innovation to achieve long-term sustainability goals, ultimately positioning the aviation sector as a leader in global efforts to combat climate change.
