Crusoe
Built its brand on flared gas; builds Stargate on a Texas gas plant.
In plain words
How scores workCrusoe scores 45 out of 100 — middle of the pack. Some disclosure or clean-energy commitments, offset by rising emissions or blind spots. Confidence in this score is good confidence (B).
What helps
- Water · Closed-loop cooling at Abilene evaporates no water in normal operation; the city's mayor puts annual use at about half a day of municipal consumption.
- Conduct · Sites in wind-rich West Texas and uses closed-loop cooling rather than evaporative towers.
What hurts
- Carbon · Abilene pairs the ERCOT grid with roughly 360 MW of on-site gas by January 2026 and a proposal for 41 more turbines running nearly year-round.
- Commitments · 'Climate-aligned' positioning but no dated net-zero, 24/7 carbon-free or water target.
- Conduct · Abilene's generators and turbines were authorised through Texas 'permit by rule' filings with no public notice or comment.

Crusoe began by running computers on natural gas that would otherwise be flared at oil wells, claims 2.7 million tonnes of CO₂e avoided since 2018 and says Crusoe Cloud runs on 100% renewable energy; in 2025 it sold the flare-mitigation and bitcoin business to NYDIG. It is now the developer and operator of Stargate Abilene for Oracle and OpenAI: 1.2 GW, closed-loop cooling on a wind-heavy Texas grid, plus 10 gas turbines and 62 diesel generators permitted by rule, with 41 more turbines proposed. Its impact reports count 'Scope 4' avoided emissions, a category no standard recognises.
Key figures
Per-prompt and fleet metrics. Hover a title for what it means; open “How we got this number” for the working.
ecogpt.co estimate; no company figure.
How we got this number
Crusoe builds and runs the Abilene campus for Oracle and OpenAI; the dominant workload is ChatGPT, whose own figure is 0.34 Wh per average query. Uncertainty roughly ±3×.
On-site cooling only, so comparable with Google and OpenAI's figures.
How we got this number
0.34 Wh per prompt × 0.1 L/kWh (estimated WUE for closed-loop cooling). Counting the water evaporated to generate the electricity adds ≈0.61 mL.
Location-based: what the grid actually emitted. Renewable certificates would bring the market-based figure near zero.
How we got this number
0.34 Wh × 420 gCO₂/kWh (Texas grid plus on-site gas, location-based).
Location-based estimate for the AI fleet only; not comparable with a full corporate inventory.
How we got this number
800 MW × 8,760 h × 80% utilisation × 420 gCO₂/kWh (Texas grid plus on-site gas). Compute only — nothing else the company does is counted.
How we got this number
Abilene's first 200 MW came online in September 2025 and the campus is sized at 1.2 GW; the sites Crusoe operates grow several-fold in a year.
How we got this number
Crusoe describes Abilene's cooling as closed-loop with no evaporation in normal operation; a small allowance covers make-up water and peak days.
How we got this number
ERCOT ran on roughly 40% wind and solar in 2025; Abilene's on-site gas lowers the blend, while Crusoe Cloud's Iceland region is fully renewable.
Hardware & materials
The chips, power, copper and future e-waste behind the fleet — the part sustainability reports leave out
GPUs, TPUs or custom accelerators the company runs. Analyst figures are in H100-equivalents, company figures in physical chips.
How we got this number
Abilene is planned for 450,000 GB200s and was roughly two thirds built by mid-2026; Crusoe Cloud's own regions add tens of thousands more. The chips at Abilene belong to Oracle, but Crusoe operates the site. ±2×.
Megawatts the AI fleet pulls. One megawatt runs roughly 750 US homes.
How we got this number
Abilene energised 200 MW in September 2025 and is building toward 1.2 GW across eight buildings by mid-2026; Crusoe Cloud's Iceland and US regions add a few tens of MW.
Terawatt-hours per year. One TWh is a year of electricity for about 95,000 US homes.
How we got this number
800 MW × 8,760 h × 80% utilisation. Compute fleet only.
CO₂e emitted making the chips and servers before they answer a single prompt.
How we got this number
300,000 accelerators × 514 kg CO₂e each (chip plus share of the host server). Emitted in manufacturing, before the first prompt is served.
Tonnes of server hardware that will be retired in three to five years.
How we got this number
300,000 accelerators × 17 kg of server hardware each. Tomorrow's e-waste unless reused; generative AI could produce 2.5 Mt of it a year by 2030.
Tonnes of copper in cabling, busbars and transformers.
How we got this number
800 MW × 27 t of copper per MW (cabling, busbars, transformers).
Diesel backup units or gas turbines at the data centres, permitted or observed.
How we got this number
As site operator; 41 more turbines and 18 generators proposed.
Share of retired servers and parts given a second life.
Kilograms of antimony-equivalent, the life-cycle unit for scarce minerals consumed.

Incidents and developments involving this company
Stargate Abilene adds 41 gas turbines and 62 diesel generators under a permit written for dry cleaners
A Floodlight and Texas Tribune investigation found Stargate's Abilene campus was authorised to run 10 gas turbines and 62 backup diesel generators through Texas 'permits by rule' that need no environmental study, public notice or comment — and has applied to add 41 turbines and 18 generators more.
Stargate Abilene pairs the Texas grid with ~360 MW of on-site gas
OpenAI's flagship Stargate campus went live in September 2025 with 200+ MW and is scaling toward 1.2 GW. Cleanview's tracking shows 29 gas turbines ordered and roughly 360 MW of behind-the-meter generation built by January 2026.
