Graphite

This commodity's rows from strata's GCAM-CMM input bundle - graded supply curves (USGS reserves × benchmark cost model, 1975 USD/kg per GCAM convention), demand intensities, and the basis lineage that says exactly what each figure counts. These are inputs toGCAM: strata is the data; the model and its runs are PNNL's. Every file keeps its provenance header.

• no dataNo commodity-decomposed scrap or end-of-life flows - No USGS MCS Fig13 scrap rows. EU WEEE / battery EOL flows (Phase 6.1.1) are country-keyed only - see country profiles.
• datedExport-restriction inventory ends 2020 - The OECD industrial-raw-materials inventory (vendored snapshot) reports HS-line measures only through 2020; restrictions enacted since are not reflected in the measure table.
• narrowConsumption geography is single-economy (United States) - Reported consumption covers one economy only - the world usage split must be read from trade flows, not from a consumption table.

The eight-stage lens, the observed-vs-estimated membrane, stage-honest supply, per-stage concentration, ownership resolution and the demand lens - the full method is illustrated live on copper, nickel and lithium.
