Audited planning profile

This shared daily profile applies a 3× editable baseline across 1 model period to the air travel change model.

USE THIS PROFILE TO

Compare resource use or environmental impact with the same boundary, quantity and time horizon.

DECISION RULE

Use the absolute difference for budgeting and the percentage difference for comparing impact. Define a consistent allocation rule so shared usage is not counted twice. Use a typical day and separately test peak or exceptional days.

NOT INCLUDED

Emission factors, lifecycle boundaries, grid mix, water stress and local waste treatment differ by source and location.

VERIFY BEFORE ACTING

Use a dated, regional factor from an official inventory or recognized lifecycle dataset and state the boundary.
