Audited planning profile
This lean five-year profile applies a 0.75× editable baseline across 60 model periods to the air travel change model.
Use the absolute difference for budgeting and the percentage difference for comparing impact. Treat the lean scale as a lower-bound plan and test whether essential fixed costs still fit. Treat maintenance, replacement and compounding assumptions as material over five years.
Emission factors, lifecycle boundaries, grid mix, water stress and local waste treatment differ by source and location.
Use a dated, regional factor from an official inventory or recognized lifecycle dataset and state the boundary.
