Sustainability reference
Forty-three impact pathways across seven sectors — the specific routes by which everyday production reaches the systems that absorb it.
SCROLL
Each pathway carries a superscript pointing to the reference that documents it. These are topic-level references from primary agency and intergovernmental publications — they establish the mechanism and its sector, not a specific figure. The grouping into seven sectors, and the single air / water / soil tag on each row, are editorial judgments; several pathways reach more than one medium. Check the source before citing any number.
