CAAFI (Commercial Aviation Alternative Fuels Initiative) is a cooperative effort among interested stakeholders to bring commercially viable, environmentally sustainable alternative aviation fuels (e.g., aviation biofuel) to market. The potential of these fuels to reduce airline CO2 emissions is anticipated to complement and possibly exceed reductions from technical and operational improvements. CAAFI is co-sponsored by the Aerospace Industries Association (AIA), Airports Council International - North America (ACI-NA), the Airlines for America (A4A) and the Federal Aviation Administration (FAA). CAAFI consists of approximately 450 organizations and more than 800 stakeholders. These include members of other U.S. and non-U.S. government agencies and trade associations, as well as energy producers, university faculty, nongovernmental organizations and consultants. CAAFI functions as a clearinghouse, facilitating the exchange of information about and coordination of private-sector and governmental initiatives supporting the development and commercialization of "drop-in" alternative aviation fuels (i.e., fuels that can directly supplement or replace petroleum-derived jet fuels). CAAFI is also exploring the long-term potential of other fuel options. == Function and focus == CAAFI primarily serves as a means of exchanging information and coordinating stakeholder efforts. This is done through the holding of technical workshops, outreach to domestic and international aviation, energy, and financial industry forums, and communication with the news media. CAAFI participants are evaluating alternative jet fuels in teams focused in four areas: Fuel Certification and Qualification--to ensure the safety of any alternative fuels given the demanding environment posed by aviation operations, participants have created a new jet fuels approval process via the ASTM International standard setting body. Fuel approval enables the safe use of alternative jet fuels and guarantee manufacturer, user and regulatory confidence in them. Three alternative jet fuel production pathways have been approved to date with seven others in progress (see Certification and Qualification of Alternative Jet Fuels section below). Research and Development--to improve understanding of the broad range of new fuel production technologies and feedstocks that can be applied to aviation, participants are sharing analyses and identifying and coordinating research activities. Environment--to assess the spectrum of environmental impacts of any alternative fuel options developed, participants are working to measure engine emissions that affect air quality and quantify the full life-cycle greenhouse gas emissions resulting from the fuel production process including feedstock extraction and transport, fuel processing, fuel distribution and land use changes. Business and Economics--to facilitate the deployment of alternative jet fuels in the marketplace, participants are connecting fuel producers and consumers, evaluating the business case for use of alternative jet fuel, and identifying opportunities for deployment. CAAFI participants meet regularly to update the state of alternative jet fuel developments in these areas, identify gaps and hurdles, and decide on next steps required in the research, development and deployment process. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Commercial Aviation Alternative Fuels Initiative」の詳細全文を読む スポンサード リンク
