Every lab, cloud and open-weight provider we track, with the evidence behind each score.
The only frontier lab with a peer-reviewed life-cycle assessment.
The most detailed per-prompt disclosure — attached to the fastest-growing footprint.
Small on-device models by default; the cloud part is opaque.
District heating from Finnish GPUs; a gas-to-fuel-cell pivot in New Jersey.
Created the AI Energy Score; runs its agents on other people's models.
Small open models, 80% renewable electricity, net zero by 2030.
Best-in-class water engineering, emissions 58% above its own baseline.
Runs its own operations on 100% renewables; its chips are the industry's footprint.
Built the AI Energy Score; hosts a million models on other people's clouds.
Half its electricity now green, PUE capped at 1.25, GPUs rationed by export rules.
The lowest disclosed water intensity, inside the largest and fastest-growing footprint.
Model cards disclose training emissions; Hyperion will be powered by new gas plants.
Open models anyone can benchmark; own data centres now 74% clean electricity.
Co-author of the AI Energy Score, with no footprint report of its own.
100% carbon-free for the public cloud; the AI campuses run on grid plus gas.
Own Kunlun chips, PUE 1.19, and renewable power stuck in single digits.
Built its brand on flared gas; builds Stargate on a Texas gas plant.

A safety-first brand with no environmental report — and gigawatts on order.
A single blog-post number, and gigawatts of gas-backed capacity on the way.
A trillion-parameter open model trained on sanctioned H800s; no footprint published.
A dinner-plate chip drawing 23 kW; six data centres; no environmental report.
Claims a tenth of the energy per token; measured by no one; now licensed to NVIDIA.
Search-augmented answers on other people's models, with nothing disclosed.
Every image costs five to ten chat prompts of electricity; nothing is disclosed.
China's biggest Nvidia buyer; 50 trillion tokens a day; no emissions data.
250,000 GPUs, 1.3 GW contracted, not one sustainability number.
First 'AI tiger' to list; a reported 1 GW all-domestic-chip campus; nothing on emissions.
Tens of thousands of GPUs for Microsoft and NVIDIA; not one environmental number.
81 gas turbines across two sites, most of them beyond their permits.
