Abstract:
The aviation sector contributes 2.5% of global greenhouse gas (GHG) emissions, with projected growth leading to a tripling of emissions by 2050. In response, the International Civil Aviation Organization (ICAO) introduced the Carbon Offset and Reduction Scheme for International Aviation (CORSIA) in 2016, aiming for carbon-neutral growth from 2020 onwards. This study provides an overview of the CORSIA framework and its methodology for calculating life cycle emissions values for Sustainable Aviation Fuels (SAF). A case study on animal fats as a SAF feedstock highlights methodological challenges in reconciling different legislations and geographical boundaries. Using Life Cycle Assessment (LCA), the study evaluates the environmental impacts of processing animal fats into SAF. The findings emphasize the importance of ongoing updates and refinements to address emerging challenges and technologies in SAF production. CORSIA is a critical component in decarbonising the aviation sector, enabling the international aviation sector to monitor GHG emissions and focus on promising decarbonisation options. Ongoing data collection and model improvements are essential to meet climate objectives and ensure CORSIA&9;s success, contributing to the development of sustainable aviation bioenergy strategies and policies.
