Aircraft, trucks, and vehicles operating at airports emit gases from fuel combustion. Airplane engines release carbon dioxide, nitrogen oxides, contrails, and particulates. Despite improved fuel efficiency, CO2 emissions increased by 47% from 1990 to 2018.
Around 90% of aircraft emissions occur above 3000 feet altitude, affecting the ozone layer. Ground support vehicles at airports also emit harmful gases. Auxiliary power units, construction instruments, and stationary power sources contribute to emissions.
Nitrogen oxides emitted by aircraft contribute to ozone formation. At higher altitudes, these emissions have a greater global warming effect.
Aircraft and aviation equipment generate significant noise pollution. The noise can disrupt sleep patterns and increase cardiovascular risks for people living near airports.
Jet fuel, chemicals, and deicing fluids used at airports can lead to water pollution. Deicing fluids, in particular, can contaminate nearby water bodies and consume oxygen necessary for aquatic life.
The environmental issues associated with the aviation industry pose a threat to the sustainability of our ecosystem. Air pollution, noise pollution, and water pollution have adverse effects on both natural environments and human health.
Efforts are being made to address these issues. Companies are exploring the use of biofuels to reduce harmful emissions. Higher bypass engines are being employed to reduce noise pollution. Additionally, the concept of liquid hydrogen-powered aircraft aims to minimize harmful gas emissions by 2035.
As air transportation continues to grow, it is imperative to address the environmental impact it generates. Mitigating air, noise, and water pollution caused by aircraft and airport operations is crucial for long-term environmental sustainability.
