High-income-country per-capita material footprint (UNEP International Resource Panel "raw material equivalents" consumption-based metric) has not declined materially over 2000-2022 -- mean change across the high-income panel is within +/-10% of 2000 levels -- despite a documented decline in territorial CO2 emissions over the same window. The consumption-based material-throughput stagnation refutes green-growth claims of broad-based decoupling and supports the PK-degrowth offshoring critique that headline emissions decoupling reflects production relocation rather than throughput reduction.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
SUPPORTED iff (a) pooled HIC mean MF/cap 2022 / 2000 in [0.90, 1.10] (i.e. < 10% decline AND < 10% rise -- the "unchanged" claim), AND (b) territorial-minus-consumption decoupling gap > 5 percentage points (offshoring signature visible). REFUTED if MF/cap pooled mean fell by > 15% (decoupling claim defensible) OR rose by > 15% (footprint expanded, not "stable"). PARTIAL between bounds. METHOD_VALID requires UNEP IRP / OWID material-footprint panel for >=15 of 20 HIC sample countries 2000-2022; if MF series unavailable, full inconclusive on the primary leg.

Two-leg descriptive test on the high-income panel 2000-2022. Leg A (material-footprint stagnation): population-weighted mean MF/cap 2022 / 2000 within 0.90-1.10 (not materially declined). Leg B (territorial-vs-consumption divergence): population-weighted mean territorial CO2/cap 2022 / 2000 < 1.0 AND consumption-based CO2/cap 2022 / 2000 declines by less than territorial-side declines (offshoring signature). Country-level dispersion reported. Also reports MF/GDP intensity (which has declined in some HIC countries) -- the distinction between intensity-decoupling and absolute-MF decoupling is the spec's headline finding.

The consumption-based material-throughput stagnation refutes green-growth claims of broad-based decoupling and supports the PK-degrowth offshoring critique that headline emissions decoupling reflects production relocation rather than throughput reduction.

Notes
PK-degrowth offshoring critique against the headline-decoupling claim. UNEP IRP material-footprint per capita is the canonical consumption-based throughput metric (Wiedmann et al. 2015; Hickel & Kallis 2020). Series is not on disk in current OWID vintage of this repo (per material_footprint_cap_feasibility notes). Spec hard-gates inconclusive on the MF leg until UNEP IRP fetcher lands or OWID slug coverage extends. TODO genuinely unregistered data sources flagged here: - UNEP IRP material-footprint accounting (NOT a registered publisher in publishers.yaml). owid:material-footprint-per-capita slug exists but is not on disk in current vintage. Either register UNEP IRP directly OR extend the OWID fetcher to pull the material-footprint slug.
