Compare the same service, not just the same square metre
Align area, life, finish and repeat deployments before comparing impacts.

Compare outcomes. Show the assumptions.
Useful comparisons begin with the same functional outcome and a valid method. Missing data should produce a clear action plan, not a precise invented footprint.
Align the function
Specify area, appearance, service life, actual or planned deployments and required components.
Choose the boundary
Show manufacturing, graphic refreshes, transport, storage, maintenance and treatment assumptions where relevant.
Keep factors attributable
Record exact identifiers, units, source, version, geography, year and applicable method. Organisational reporting factors are not a complete materials LCA database.
Separate scenario from history
Planned reuse and hypothetical avoided activity remain estimates. Preserve observed deployments and outcome evidence separately.
