The global aviation industry is striving towards achieving net-zero carbon emissions by 2050, with major airlines committed to sustainability practices. However, supply chain challenges, including delays in delivering fuel-efficient aircraft and engines, pose significant barriers. Manufacturers' inability to meet promised timelines due to raw material shortages, labor constraints, and pandemic disruptions hinders airlines' efforts to reduce emissions. Operating older aircraft increases fuel consumption and emissions, impacting both sustainability and operational costs. Collaborative efforts, such as manufacturers fulfilling commitments, streamlining supply chains, and investing in R&D, are essential. Airlines advocate for government support and regulatory reforms to facilitate sustainable aviation solutions. Governments play a crucial role in funding research, incentivizing sustainable fuel production, and establishing global standards. Despite challenges, innovative solutions like electric/hybrid aircraft and hydrogen-powered planes offer hope for a greener future. The industry's collective effort involving stakeholders' collaboration, innovation, and accountability is key to achieving net-zero emissions and ensuring sustainable aviation.
