Aviation taxation and subsidies
Aviation taxation and subsidies includes taxes and subsidies related to aviation. Taxation is one of several methods to mitigate the environmental impact of aviation.
EU aviation fuel taxation
Taxation of aviation fuel in the European Union is regulated by the Energy Taxation Directive (2003/96/EG) of 27 October 2003. This prohibits the taxation of commercial aviation fuel, except for commercial domestic flights or by bilateral agreement between member states. As of 2023, commercial aviation fuel is currently tax exempt under the legislation of all member states of the European Union. This tax exemption has been criticised on environmental grounds. Jet engines using kerosene fuel developed rapidly after 1950.
Sustainable biofuel
Sustainable biofuel is biofuel produced in a sustainable manner. It is not based on petroleum or other fossil fuels. It includes not using plants that are used for food stuff to produce the fuel thus disrupting the world's food supply. Low-carbon fuel standard In 2008, the Roundtable for Sustainable Biofuels released its proposed standards for sustainable biofuels. This includes 12 principles: "Biofuel production shall follow international treaties and national laws regarding such things as air quality, water resources, agricultural practices, labor conditions, and more.
Cirrus cloud
Cirrus (cloud classification symbol: Ci) is a genus of high cloud made of ice crystals. Cirrus clouds typically appear delicate and wispy with white strands. Cirrus are usually formed when warm, dry air rises, causing water vapor deposition onto rocky or metallic dust particles at high altitudes. Globally, they form anywhere between above sea level, with the higher elevations usually in the tropics and the lower elevations in more polar regions.
Black carbon
Chemically, black carbon (BC) is a component of fine particulate matter (PM ≤ 2.5 μm in aerodynamic diameter). Black carbon consists of pure carbon in several linked forms. It is formed through the incomplete combustion of fossil fuels, biofuel, and biomass, and is one of the main types of particle in both anthropogenic and naturally occurring soot. Black carbon causes human morbidity and premature mortality. Because of these human health impacts, many countries have worked to reduce their emissions, making it an easy pollutant to abate in anthropogenic sources.
