Air travel significantly contributes to global carbon emissions, with aviation accounting for approximately 2-3% of total greenhouse gas emissions. The combustion of jet fuel releases carbon dioxide and other pollutants, exacerbating climate change. As demand for air travel continues to rise, addressing these emissions is increasingly urgent. Potential solutions include the development of more fuel-efficient aircraft, investment in sustainable aviation fuels, and implementing carbon offset programs. Additionally, encouraging alternatives such as train travel for short distances can help mitigate emissions. By prioritizing sustainable practices within the aviation industry, we can reduce the environmental impact of air travel and promote a greener future.
