Audited planning profile

This household half-year profile applies a 4× editable baseline across 6 model periods to the household gas projection model.

USE THIS PROFILE TO

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

DECISION RULE

Review both the projected result and the assumed recurring change before relying on the forecast. Use household totals and include irregular shared costs rather than only one person's spending. 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.
