Industrial facilities in Norway — directory, sectors & CO₂

Industry mix (Norway)

Facility counts by sector, Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0).

The state of Norway's industrial emissions

Across the 45 Norway industrial facilities with an estimated CO₂ figure (Climate TRACE), total emissions are about 14.4 Mt CO₂e/yr. The single largest emitter, Equinor Mongstad Crude Oil Refinery (oil-and-gas-refining), accounts for about 18% of that. The biggest sectoral share comes from other-metals. Among facilities with a known operator, the top three — Equinor ASA, Norsk Hydro ASA, Sunndal Primary Production — account for roughly 37%. Most of these facilities sit in a continental Köppen climate zone.
