Aviation Energy Analysis Model (AEAM)

Scenario-based projections of fleet size, sustainable aviation fuel diffusion, fuel consumption, and TTW/WTW carbon emissions for China civil aviation, 2025-2060.

Project Overview

The Aviation Energy Analysis Model evaluates decarbonization pathways for China's civil aviation sector. It links RPK/CTK demand, passenger and cargo fleet evolution, fuel competition between fossil jet fuel and SAF, and emissions accounting under TTW and WTW boundaries.

Fuel, Policy, Segment, and Scenario Structure

The model links fuel substitution, carbon pricing, aviation segments, and scenario analysis in a layered evaluation framework.
