Eight metrics — real-world trajectories, 2000–2026 (provisional)

How to read this: each line is the real-world trajectory of the metric, indexed to its year-2000 baseline of 100, so a rising line means that activity is genuinely increasing — the Animal Headcount line rises because head-counts are rising. The legend and readout show each metric's aggregated world total in physical units (head, tonnes, hectares, people); the lines stay indexed so all eight share one scale. For seven of the eight (head-counts, emissions, land use, trade, feed, output and farm jobs) a rising line means more animal-agriculture pressure, which pushes the headline CSI down — the CSI consumes the inverse of these. Only the plant-based transition (consumer) rising is good for the CSI. Use the View buttons to switch between the real-world activity and the CSI sub-index the index consumes; the readout shows both numbers for the selected point.

All eight metrics on one shared index scale (2000 = 100), reflected into real-world orientation from the published sub-index histories so a rising line always means the activity is rising. Each line ends at its last published value — a true ragged edge. Headcount (to 2026), GHG (to 2026), Land use (to 2026), Trade (to 2026), Feed (to 2026), Output (to 2026), Employment (to 2026), Consumer (to 2026) now extend past 2023 on real current sources (national statistics, national production and Climate TRACE); the remaining metrics end at 2023, FAOSTAT's latest, held flat for the composite but not drawn as observations here. The shared scale spans every metric (roughly 59 to 173), so a recent move of a few index points is a small but real slope, not a flat line. The CSI consumes the inverse of the seven animal-agriculture metrics, so the headline CSI falls as they climb. Select a metric above to trace it; hover or keyboard-focus a point to inspect it. Illustrative/provisional until a reproducible production pipeline certifies a release.
