The Boeing CASCADE Climate Impact Model

Boeing has released CASCADE, a public climate‑impact model that lets users explore different pathways for aviation to reach net‑zero CO₂ by 2050. The tool combines global traffic and fleet data with scenario sliders for aircraft technology, operations, energy (including SAF, electricity and hydrogen) and offsets, providing time‑series emissions and efficiency metrics.

Designed for airlines, policymakers, energy providers and researchers, CASCADE stands out for its life‑cycle perspective, accounting for emissions from production, distribution and use of alternative fuels rather than focusing only on in‑flight CO₂. For Azero2050 and the wider EU debate on ETS, CORSIA and SAF roadmaps, it offers an industry‑developed, transparent framework that can complement academic modeling and help stress‑test decarbonisation strategies under consistent assumptions.
