Abstract Using lightweight materials in aircraft structures, especially carbon fiber reinforced polymer (CFRP), can be an option for achieving aviation's ambitious emission reduction goals. However, using CFRP associated with adverse environmental and economic impacts, which relativize its potential benefits. Nevertheless, the extent of advantages disadvantages increased use entire airframe is still uncertain, as existing studies relate to specific components or estimated weight savings. This article aims close this gap by developing detailed life cycle inventories (LCIs) structures analyzing impacts during production use. Furthermore, reinforcement effects from sustainable aviation fuels (SAFs) such are investigated determine overall impacts. For purpose, three configurations different content modeled design program “Preliminary Aircraft Design Optimization”. Afterward, LCIs developed, assessment costing applied. Subsequently, analysis conducted where SAFs replace fossil kerosene investigate further reductions The results indicate that increasing reduces Despite higher costs, more cost‐effective flight operations possible. Additionally, there a effect through content, reduce climate‐damaging emissions several magnitudes compared alone.
