Animal Headcount Index
Tracks the size of farmed-animal populations. A measured fall in headcount lifts the sub-index; a rise lowers it.
Composite Sustainability Index.
CSI measures animal-agriculture pressure as a single index.
The Composite Sustainability Index is a modular, percentage-based benchmark for animal agriculture's ecological and ethical status.
Data state: provisional
The CSI turns several animal-agriculture signals into one readable index. Lower livestock counts, reduced emissions, lower land use and related improvements can lift the index. Worsening conditions can lower it. UNPT uses the CSI as a reference for its stability design, which means the index page must make every metric, source and validation step visible.
Headline CSI
Data state: provisionalThe value is computed from real national and international sources; “provisional” means it is not yet certified by a reproducible production pipeline, not that the data is synthetic. The 2026 reading is a ragged-edge nowcast: the head-count, GHG, animal-product output, feed and employment metrics move with real current sources (national statistics, Climate TRACE, national + USDA PSD production, ILO-modelled and national labour-force data); land use moves on a provisional geospatial nowcast — the official pasture-area source remains the reconciliation anchor, while current satellite and national land-cover products prevent the land-use signal from going stale. The trade and consumer metrics carry forward from 2023. The fully-measured base period is 2023.

Annual CSI. 2000–2023 are observed; the hollow 2024–2026 points are a ragged-edge nowcast — the head-count, GHG, animal-product output, feed and employment metrics move with real current sources (national statistics, Climate TRACE, national + USDA PSD production, ILO-modelled and national labour-force data), and land use moves on a provisional geospatial nowcast (driver-filtered forest conversion and national land-cover statistics; the official pasture-area source remains the reconciliation anchor). The trade and consumer metrics carry forward from 2023. Real values only, never fabricated. Hover or keyboard-focus a point to inspect it.

- Source status
- The provisional source bundle is free-public-WORLD-2026, last updated 31 Dec 2026 with 90.99% illustrative confidence. Validation checks: schema: passed; source-hash: passed; nowcast-carry-forward: applied; release-certification: not-run.
- Where the evidence lives
- The source registry, publication calendar, freshness and data-quality layer are on Global Optics.
Why is this snapshot provisional?
The headline CSI is computed from real national and international sources, but it is labelled provisional because the benchmark-certification gate fails closed: a snapshot becomes certified only once a reproducible production pipeline verifies a release. It is a transparency reading, not yet a certified benchmark — and “provisional” means uncertified, not synthetic.
Still required to certify
- No reproducible production pipeline has certified this release yet — two machines must independently produce the same snapshot and source-bundle hash.
- No publishable release certificate has been issued for this snapshot.

Protocol and feed status
- Dashboard
- Static CSI dashboard. The snapshot above is the published static reading.
- Live stream
- Live SSE feed disabled — the static export serves the latest published snapshot. This is the designed degradation, not an outage.
- Protocol mechanics
- No live intervention controller, no active mint, burn or rebase, no hard peg. v1 is fixed-supply (30,000,000,000 UNPT) and the CSI never changes user balances.
CSI products
Eight sub-index products compose the CSI.
Each sub-index is a first-class benchmark with its own figure, chart, signals and evidence; the CSI is their weighted composition over 101. Open a product for its detail, or follow it through to the source layer in Optics. Every value is illustrative and provisional until a reproducible production pipeline certifies a release.
Animal Agriculture Greenhouse-Gas Index
Tracks greenhouse-gas emissions attributed to animal agriculture. Lower emissions lift the sub-index.
Animal Agriculture Land-Use Index
Tracks land allocated to animal agriculture, including grazing and feed cropland. Less land use lifts the sub-index.
Animal Product Trade Index
Tracks traded volumes of animal products. A fall in animal-product trade lifts the sub-index.
Livestock Feed Production Index
Tracks feed grown for livestock. Lower feed production lifts the sub-index.
Animal Product Output Index
Tracks output of meat, dairy, eggs and other animal products. Lower output lifts the sub-index.
Animal Agriculture Employment Index
Tracks employment in animal agriculture as a transition signal. A measured decline lifts the sub-index.
Consumer Transition Index
Tracks the shift towards plant-based and alternative consumption. A rise lifts the sub-index — the only transition-positive metric.
How the CSI is calculated
The CSI is the weighted composition of eight sub-indexes.
The headline value is composed from the eight first-class sub-indexes above, one per methodology metric, with raw priority weights summing to 101. The table below shows each sub-index’s raw weight, its weight as a fraction over 101, its latest value and its weighted contribution, plus the direct-versus-composed parity status that gates composition mode.

CSI is the weighted average of the eight canonical sub-indexes, 101/101 of the total. A lens is never counted a second time.

Direct-vs-composed parity
Not yet verified.No parity record is published, so the direct-vs-composed gate is reported as not yet verified rather than as a pass.

Sub-index tiles (8 benchmarks)
CSI movement shows direction, not moral certainty.
A higher CSI score indicates a measured reduction in livestock-related pressure across weighted metrics. A lower CSI score indicates a measured increase in that pressure.
Every CSI update needs a source trail. Each update should show the source type, reporting period, validation state, anomaly state and update timestamp.
Methodology version and proof status.
The headline reading reflects the activated csi-v1.1.0 methodology, certified on the candidate proof chain. The production proof ledger is being regenerated under the same methodology; until that completes, the per-epoch ledger and composition records may still carry the prior csi-v1.0.0 figures.
Every published CSI and sub-index number carries an explicit data-state label and stays provisional until a reproducible production pipeline certifies a release.
