Coverage

Data coverage notes

group-levelHafnium: USGS publishes no reserves estimate - USGS Mineral Commodity Summaries 2026 carries no quantitative reserves figure for hafnium - neither a U.S. nor a world total. USGS does not separately estimate reserves for this minor metal. The empty reserves table reflects the source's reporting grain, not missing strata coverage.
no dataNo commodity-decomposed recycling data - No USGS MCS Fig13 scrap rows. EU WEEE / battery EOL flows (Phase 6.1.1) are country-keyed only - see country profiles.
datedMaterial-flow analysis is historical - All 4 material-flow records date to 2000 or earlier (Yale STAF era). They describe the anthropogenic cycle of that period, not today's system.
datedEnvironmental footprint is dated - Cradle-to-gate intensity rows carry a 2008 inventory vintage (Nuss & Eckelman-era LCA). Current-process footprints are not yet in scope.

Methodology

How strata reads a commodity

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.
