In the ‘sustainable development scenario’ (SDS), low-carbon fuels will meet 7% of international shipping and 9% of aviation fuel demand in 2030. However, current biofuel consumption is minimal in both these subsectors. Some progress has been made in aviation. Flights using biofuel blends have surpassed 200,000; a continuous biofuel supply is available at six airports; and policy support was enhanced in the United States and Europe in 2018. Still, aviation biofuel production of about 15 million litres in 2018 accounted for less than 0.01% of aviation fuel demand. This means that very significant market development is needed to deliver the aviation biofuel production required to be on the SDS trajectory in 2030. To scale up biofuel consumption, market and policy frameworks must be devised that reflect the international nature of these sectors. This task falls within the remit of the ‘International Civil Aviation Organization and the International Maritime Organization’.

Depending on the feedstock and processing route, biofuel GHG emission can be relevant. LCA methodologies applied on biofuel production and use have been developed during the last decades, producing reliable results, essential to support and stimulate the introduction of aviation biofuels for regular use. Sustainable aviation biofuel can mitigate about 80% of fossil jet fuel emission, offering the same energy service. For instance, LCA of aviation biofuel from sugarcane (DSHC, Amyris route) was evaluated and showed net life cycle emissions at around 15 g CO2eq/MJ, which means there was mitigation of around 82% of GHG emissions from fossil kerosene (IDB, 2013).
Biomass as a Source for Heat, Power and Chemicals

Aviation biofuel is a biofuel used for aircraft. It is considered by some to be the primary means by which the aviation 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 2011. Since then, some airlines have experimented with using biofuels on commercial flights (Wessof, 2017).
A carbon footprint analysis of renewable energy technology adoption in the modal substitution of high-speed rail for short-haul air travel in Australia
Published in International Journal of Sustainable Transportation, 2018
When compared to fossil fuel derived JETA1, the implementation of HRJ fuel for the air mode resulted in a 12%–49% reduction in CO2 emissions per passenger trip. As previously noted with relation to Figure 3, the wide variance in CO2 mitigation of the biofuel technology for the air mode was due to the increasing percentage share of biofuel over the longitudinal period. In 2056, with a maximum 60% biofuel share of fuel combusted for the air mode, the life cycle CO2 per air passenger trip was substantially reduced by 49%, demonstrating the significant mitigation potential of aviation biofuel technology.
