4. Application of LCA to Aviation Fuels

This comprehensive study examines the utilization of Life Cycle Assessment (LCA) in the context of aviation fuels, offering a critical evaluation of their influence on greenhouse gas (CHG) emissions. The research emphasizes the crucial significance of biofuels in effectively reducing CHG emissions across their entire lifecycle. This statement highlights the negative consequences of utilizing alternative fuels derived from fossil feedstocks on CHG emissions, even in cases where carbon capture and storage techniques are implemented. The aforementioned impacts are juxtaposed with conventional kerosene, thereby emphasizing the ecological ramifications associated with diverse fuel selections. The research identifies Biomass to Liquid (BTL) as the most favorable strategy in terms of mitigating CHG emissions, as it aligns with the Renewable Energy Directive’s mandate of achieving a 60% reduction in life cycle emissions. Additionally, it is worth mentioning that these technologies have already been widely adopted and implemented, enabling the diversification of fuel supply in response to the growing demand. The study additionally suggests that market dynamics, which can be influenced by escalating crude oil expenses or conditions of oil scarcity, may inherently drive the adoption of these fuels. This study not only offers substantial contributions to the ongoing discussion on the sustainability and environmental implications of aviation fuels but also establishes a foundation for further investigation in this crucial field of inquiry.
