Cosmo Oil Sakai Refinery is a refinery in Japan. Refineries heat, fractionate and chemically transform crude oil into fuels and petrochemical feedstocks through energy-intensive distillation and cracking — extremely demanding on steam generation and heat recovery. It is operated by Cosmo Oil. It emits about 855,661 t CO₂e a year from Climate TRACE. That is 0.52% of the CO₂e from the 105 facilities in Japan that have an emissions figure in IndustryAtlas.

In context: how this facility compares

Subsector: oil-and-gas-refining. As refinery, it requires high process heat (typically 200–600°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Refineries heat, fractionate and chemically transform crude oil into fuels and petrochemical feedstocks through energy-intensive distillation and cracking — extremely demanding on steam generation and heat recovery.

Carbon cost and Scope 1 emissions

At its reported 856k t CO₂e/yr (Scope 1), Cosmo Oil Sakai Refinery carries no domestic carbon price, and its products are not CBAM-covered goods, so there is no border-carbon liability. At the EU ETS reference price (€75/t) the emissions carry an indicative carbon value of €64.5M/yr.
