Aggregated overview of publicly known Summit Materials sites — capacity, CO₂ intensity, annual emission estimates and links to primary references (company reports, GCCA GNR, IEA, USGS, EU ETS).
Official website ↗Summit Materials, Inc. — US aggregates and cement producer combining Continental Cement with the former Argos USA assets across more than 20 states. 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.
Not enough data to plot.
Benchmark: world avg 585 kg/t (GCCA GNR 2022) · IEA 2030 target ≈ 500 kg/t
