Aggregated overview of publicly known Sumitomo Osaka Cement sites — capacity, CO₂ intensity, annual emission estimates and links to primary references (company reports, GCCA GNR, IEA, USGS, EU ETS).
Official website ↗Sumitomo Osaka Cement Co., Ltd. — Japanese cement maker combining clinker production with advanced-materials businesses, and a heavy user of industrial waste and sewage sludge as kiln inputs. src ↗
Each fact carries a citation badge: src links to the primary reference (Wikipedia entry, annual report or investor relations); a dashed badge means no curated source is on file and the link runs a public search.
Group-level figures cover all business lines (cement, aggregates, ready-mix) and may exceed the sites tracked on this map.
Benchmark: world avg 585 kg/t (GCCA GNR 2022) · IEA 2030 target ≈ 500 kg/t
Estimate = plant capacity × intensity. Not audited emissions.
