Quirks

energy + ghg axes only - no water (study reports acidification/eutrophication proxies, not m3/kg)
2008-vintage ecoinvent 2.2; co-product allocation drives 42/63 metals; single global average, not per-process-stage

v1 emitter for the dossier environmental section, replacing the registration-gated Argonne GREET. Vendored-CSV CacheOnlyFetcher; 50 of 61 strata commodities covered (industrial minerals out of a metals LCA).
