Hannah Ritchie’s analysis visualizes food emissions using Poore and Nemecek’s published meta-analysis. It separates livestock, crops, land use and supply-chain contributions, explaining category boundaries and the distinction between food-system and global totals.
Keep denominators and system boundaries visible; categories cannot be combined safely until overlaps and exclusions are resolved.
A synthesis of published estimates, not newly collected emissions measurements. Food-system categories and global totals have different denominators; the historical estimates are not a live inventory.
AI use: Not reported in the source.
The inspected source does not report AI-assistant use by its authors.
A useful public example is not an assessment of a reader, a publisher or a Better Loop member.
Authored practice suggestion
Use material you are allowed to work with. This suggestion is preparation; it does not record a completed task or an improvement.
Category totals reconcile to their stated denominator; overlaps are explained; every numerical claim is traceable to the chart or its cited study.
Private practice needs no account. Your configured model provider may process the evidence you select.
