Sustainable flight refers to aviation practices that aim to reduce the environmental impact of air travel. This includes using more fuel-efficient aircraft, optimizing flight routes, and implementing alternative fuels, such as biofuels or hydrogen. These efforts help lower greenhouse gas emissions and minimize noise pollution. Additionally, sustainable flight involves innovations in technology and design, such as electric or hybrid planes. Airlines and manufacturers are increasingly focusing on sustainability to meet regulatory requirements and consumer demand for greener travel options. By adopting these practices, the aviation industry can contribute to a more sustainable future for our planet.
