Audited planning profile

This conservative half-year profile applies a 1.2× editable baseline across 6 model periods to the household waste compare model.

USE THIS PROFILE TO

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

DECISION RULE

Use the difference between option A and option B; keep the scale and horizon identical for both. Use this profile when protecting downside matters more than optimizing the headline result. Review the assumptions midway because prices and usage may already have changed.

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.
