Aviation has a long and successful record of improving fuel efficiency over time; however, it is still facing significant pressure to reduce its greenhouse gas (GHG) emissions and offset emissions that may result from growing demand for air travel. Industry stakeholders have committed to a wide range of measures for reducing GHG emissions, such as further fuel efficiency improvements, advanced air traffic management techniques to shorten routes, more efficient operations, and market-based and regulatory measures to further reduce emissions. Perhaps the most promising approach for reducing aviation GHG emissions is the use of alternative fuels. These fuels can also reduce surface emissions, which could also be a barrier to the growth of aviation. Environmentally beneficial alternatives to current Jet A fuel are in the early stages of commercialization, although rapid progress is being made in their development. It is important for stakeholders to understand how these new fuels will fit into the current system, how they will move from fuel production sites to airports, and what is involved on the part of the airports to accommodate the fuels and deliver them to aircraft. |
