 used for aircraft
Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air, or, in general, the atmosphere of a planet. An aircraft counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines.Although...

. Aviation biofuel is widely considered by the aviation industry to be one of the primary means by which the industry can reduce its carbon footprint. After a multi-year technical review from aircraft makers, engine manufacturers and oil companies, biofuels were approved for commercial use in July of 2011. Since then, multiple airlines have begun the use of biofuels on commercial flights. The focus of the industry is on second generation sustainable biofuels that do not compete with food.

Rationale for aviation biofuels

Aviation's share of the greenhouse gas emissions is poised to grow, as air travel increases and ground vehicles use more alternative fuels like ethanol and biodiesel. Currently aviation represents 2% of global emissions, but is expected to grow to 3% by 2050. In addition to building more fuel efficient aircraft and operating them more efficiently, changing the fuel source is one of the few options the aviation industry has for reducing its carbon footprint. While solar, electric and hydrogen propelled aircraft are being researched, it is not expected they will be feasible in the near or medium term due to aviation's need for high power-to-weight ratio
Power-to-weight ratio
Power-to-weight ratio is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power sources...

 and globally compatible infrastructure.

Concerns and challenges

There are challenges that lie ahead with bio-fuels. Bio-fuels that are vegetable oil based have a tendency to gel at slightly higher temperatures. This can be rectified with agents that are currently used for petroleum based fuels. Studies now underway, are looking at how best to utilize bio-fuel technology as a share of all transportation fuel needs in the United States. Even a percentage of overall use can and will pay large dividends both environmentally and economically.

Industry commitments and collaborations

The International Air Transport Association is an international industry trade group of airlines headquartered in Montreal, Quebec, Canada, where the International Civil Aviation Organization is also headquartered. The executive offices are at the Geneva Airport in SwitzerlandIATA's mission is to...

 (IATA) supports research, development and deployment of alternative fuels. IATA thinks a 6% share of sustainable 2nd generation biofuels is achievable by 2020, and Boeing supports a target of 1% of global aviation fuels by 2015. This is in support of the goals of the aviation industry reaching carbon neutral growth by 2020 and a 50% decrease in carbon emissions by 2050 (relative to a 2005 baseline)

A group of interested airlines has formed the Sustainable Aviation Fuel Users Group (SAFUG). The group was formed in 2008 in cooperation with support from NGOs such as Natural Resources Defense Council
Natural Resources Defense Council
The Natural Resources Defense Council is a New York City-based, non-profit, non-partisan international environmental advocacy group, with offices in Washington DC, San Francisco, Los Angeles, Chicago, and Beijing...

 and The Roundtable For Sustainable Biofuels (RSB). Member airlines represent more than 15% of the industry, and all member CEOs have signed a pledge to work on the development and use of sustainable biofuels for aviation.

Boeing is joining other aviation-related members in the Algal Biomass Organization (ABO).

Environmental Benefits

A life cycle assessment by the Yale school of forrestry of jatropha, one source of potential biofuels, estimated a reduction in greenhouse gasses up to 85%.. In addition, biofuels do not contrain sulfur compounds and thus do not emit sulfur dioxide.

Many different standards exist for certification of sustainable biofuels. One such standard often cited by airlines is the one developed by the The Roundtable For Sustainable Biofuels .
