Audited planning profile
This shared ten-year profile applies a 3× editable baseline across 120 model periods to the household food compare model.
Use the difference between option A and option B; keep the scale and horizon identical for both. Define a consistent allocation rule so shared usage is not counted twice. Use a wide uncertainty range; small recurring assumption errors compound substantially over ten 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.
