Aircraft across the world utilize many different types of engines. However, the majority of these aircraft, even turboprop and piston-powered aircraft, have a negative effect on the environment. Each engine, especially jet engines that are used on commercial airliners and private jets, emits greenhouse gases like carbon dioxide. Many of these gases are found in contrails, and they may also include nitrogen oxide and other particles. These gases can adversely impact the climate due to polluting gases. Additionally, aircraft also emit sulfate and soot while flying, which can also impact the environment negatively. These particles may also interfere with air quality.
