What benefit do Sustainable Aviation Fuels (SAFs) offer in terms of lifecycle greenhouse gas emissions compared to traditional jet fuel?
Answer
Potentially reducing them by up to 80%
Sustainable Aviation Fuels (SAFs) are identified as a critical component for achieving decarbonization in air travel, which currently relies heavily on traditional jet fuel. The primary advantage of using SAFs is their significant potential impact on emissions; when analyzed across their lifecycle, they can reduce greenhouse gas emissions by as much as 80% compared to conventional fossil fuels. Despite this potential, the text notes that scaling up production remains a major challenge, as SAFs currently constitute less than 0.1% of total aviation fuel use, necessitating overcoming high production costs to meet ambitious future adoption goals.
