The Aerospace Industries Association (AIA) is the trade association representing the nation's aerospace and defense manufacturers.

This term is broader than SAJF as it includes fuels sourced from petroleum alternatives that may not be considered sustainable, such as coal.

ALTA is a private law entity nonprofit comprised of airlines in Latin America and the Caribbean, which aims to combine and coordinate the efforts of its members to facilitate the development of air transport in Latin America and strengthen the channels of collaboration and communication between those for mutual benefit of industry and its users.

A United States based nonprofit organization whose membership is comprised of owners and operators of liquid pipelines.

API is a national trade association that represents all aspects of the United States' oil and natural gas industry.

An entity within the Department of Energy that advances high-potential, high-impact energy technologies that are too early for private-sector investment. ARPA-E projects have the potential to radically improve U.S. economic security, national security, and environmental well-being. ARPA-E empowers America’s energy researchers with funding, technical assistance, and market readiness.

A research partnership with cost-sharing among academia, industry, and government, focused on environmental aviation topics and alternative jet fuel.

ASTM International, originally known as the American Society for Testing and Materials (ASTM), is a voluntary standards development organizations. ASTM International specifications are used for the certification of jet fuel.

A widely utilized specification that defines the properties of aviation turbine fuel for civil use and describes fuels found satisfactory for the certification and operation of aircraft and engines. The specification can be used as a standard in describing the quality of aviation turbine fuels from the refinery to the aircraft.

This practice covers and provides a framework for the qualification and approval of new fuels and new fuel additives for use in commercial and military aviation gas turbine engines. The practice was developed as a guide (e.g. for those seeking ASTM D7566 adoption of a new synthetic jet fuel blending component) by the aviation gas-turbine engine Original Equipment Manufacturers (OEMs) with ASTM International member support.

This specification defines specific types of aviation turbine fuel that contain synthesized hydrocarbons for civil use in the operation and certification of aircraft and describes fuels found satisfactory for the operation of aircraft and engines.

Previous name of A4A

A synthetic jet fuel blending component produced from the conversion of alcohols to hydrocarbon chains (in the jet fuel range) through the use of thermo-chemical processes (dehydration, oligomerization, hydrogenation, and fractionation primarily)

The Energy Policy Act of 1992 defines alternative fuels as methanol, denatured ethanol and other alcohol; mixtures containing 85 percent or more (but not less than 70 percent as determined by the Secretary of Energy by rule to provide for requirements relating to cold start, safety or vehicle functions) by volume of methanol, denatured ethanol and other alcohols with gasoline or other fuels. Includes compressed natural gas, liquid petroleum gas, hydrogen, coal-derived liquid fuels, fuels other than alcohols derived from biological materials, electricity or any other fuel the Secretary of Energy determines by rule is substantially not petroleum and would yield substantial energy security and environmental benefits.

Fats and Oils derived from animal processing, being used for conversion into fuels, including: tallow - from beef, sheep, goat processing white grease / lard - from pork processing fish oil, shellfish oil, chicken fat

A term used to summarize the amount of energy that is equivalent to the amount of energy found in a barrel of crude oil. Also known as Crude Oil Equivalent (COE).

The Biomass Research and Development Board is an interagency collaborative effort among the White House Office of Science and Technology Policy and other agencies involved in biomass research and development. The Board, which "coordinates research and development activities concerning bio-based fuels, products and power across federal agencies," is co-chaired by the USDA, and the U.S. Department of Energy. The BRDB has a Technical Advisory Committee whose role it is to provide feedback to the chairs on the overall effectiveness of the program.
