Tesoro Anacortes Refinery — United States
Refinery in United States. Approximate location 48.49437, -122.56252.
RefineryUnited StatesCO₂ estimate (modelled)
Tesoro Anacortes Refinery is a refinery in United States. Its listed capacity is 119,000 BBL per day. 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 Marathon Petroleum Corp. By capacity it ranks #55 among 119 oil refineries in United States. It emits about 1,308,701 t CO₂e a year from Climate TRACE. That is 0.23% of the CO₂e from the 1,910 facilities in United States that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 28% above the national median for this sector.

In context: how this facility compares
At 119,000 BBL per day, Tesoro Anacortes Refinery is well above the median refinery in United States (89,200 BBL per day). 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 1.3M t CO₂e/yr (Scope 1), Tesoro Anacortes 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 €98.6M/yr.
Measured CO₂: 1.2M t/yr — verified GHGRP (reporting year 2023) (9% below the modelled estimate). Modelled estimate 1.3M t/yr (Climate TRACE), high-confidence match, cross-checked via the measured-vs-modelled dataset (n=711).
Carbon price: EU CBAM €75/t · EU ETS €85/t, September 10, 2026, refreshed live via Carbon Hub. CO₂: measured (GHGRP RY2023), cross-checked vs Climate TRACE. Indicative carbon value, not the cash bill — free allocation applies; not compliance advice.

Local climate
Tesoro Anacortes Refinery sits in a warm-summer Mediterranean climate zone (Köppen Csb), at 48.5°N in the northern hemisphere.
Köppen zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
Site climate & environmental severity
This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1394 W/m² to ambient — roughly 1.07× the loss at a 20 °C reference. Reference-surface calculation at a 150 °C surface from WorldClim climate normals (ASTM C680 / ISO 12241) — an indicative per-climate comparison, not a measurement of this site’s specific equipment. Open method dataset: DOI 10.5281/zenodo.20787408 (CC BY 4.0).
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
