Planes Utilize Most Fuel During Takeoff

The world's airlines use some 205 million tons of aviation fuel (kerosene) each year, producing greenhouse gases such as carbon dioxide, nitrogen oxides, ozone, sulfur dioxide, and methane. Jet fuel is the second-largest expense to airlines after labor and can amount to 20 percent of companies' operating expenses.

The Intergovernmental Panel on Climate Change (IPCC) report in 1999 found that aircraft are responsible for 3.5 per cent of greenhouse gas emissions worldwide. Flight is one of the fastest-growing emission sources, and no technological fixes are in sight.
