4PLANET IMPACT / ISSUE
Material-intensive construction
Buildings and infrastructure consume large quantities of minerals, metals and other materials and embody substantial life-cycle impacts.
Why it matters
Construction decisions affect resource extraction and embodied emissions as well as operational energy use.
What the sources establish
UNEP's 2025/2026 buildings report identifies buildings and construction as a major source of emissions and material demand.

Published action
No project on this issue has passed the IMPACT publication gate yet. That is not evidence that no work exists.
Known and not established
- Do not infer building-level performance from global sector averages; material quantities, lifetime and energy system matter.
- This issue record is source-grounded context, not proof that any particular project, action or intervention is effective.
