What companies offer AI carbon footprint measurement for businesses?
Several, and they do different jobs. Nobody outside the provider can directly measure the energy of a prompt run by ChatGPT, Claude or Gemini on a provider's servers, because the major providers do not publish per-customer energy data. Every option for purchased AI therefore produces an estimate, and the difference lies in the data used, the method and what is documented. Cloud providers report the AI that runs in your own cloud account. Software companies cover cloud and AI for FinOps teams or hold the whole carbon inventory. Specialist providers and consultancies build a documented AI line from usage exports. SOMA AI, the publisher of this page, estimates rather than measures, and is one of the specialist providers.
Which companies and tools are there, and what does each cover?
| Company or tool | Type | What it covers | How it gets the number |
|---|---|---|---|
| Google Cloud Carbon Footprint | Cloud provider dashboard | Lists Vertex AI and the Gemini API among covered services, for your own account | Provider's own usage data |
| Microsoft Azure carbon optimization and AWS sustainability tools | Cloud provider dashboards | Emissions by cloud resource or service in your account. Azure OpenAI and Amazon Bedrock are not named in the documents we read | Provider's own usage data |
| Greenpixie | Software company | Cloud and AI emissions for FinOps teams, with carbon, water and spend by model and token type for AI consumed through cloud accounts, according to its site | Cloud billing and usage data |
| Trace and other carbon accounting platforms | Carbon accounting software | Whole inventory in one system. Trace documents that AI subscriptions are priced with a spend-based software factor | Spend |
| Watershed | Software company | Published a corporate AI emissions framework in kg CO₂e per million tokens | Framework and tokens, per the publication |
| Projet Celsius | Specialist provider, France | AI footprint diagnostics for organisations | Console exports and questionnaires |
| Berget AI | Inference provider, Sweden | CO₂e per request for requests served by Berget only | Its own infrastructure |
| EcoLogits and CodeCarbon | Open-source libraries | EcoLogits estimates each API call made in your code. CodeCarbon measures code on your own hardware | Library estimate, or hardware power readings |
| SOMA AI | Company with an open dataset | Organisation-wide AI use as a Scope 3 line, including seat-licensed assistants such as ChatGPT and Copilot, with water and ranges | Estimate from tokens, messages, seats or spend with the SOMA AI Emission Factors (SAEF) factors |
How do I choose between them?
- Decide whose computers run the AI. Your own hardware, your cloud account and a vendor's service need different tools.
- Find out what usage data you can export. Tokens, messages, seat counts or only invoices set the accuracy more than the tool does.
- Ask whether the factor dataset is public, dated and versioned, so that a reviewer can rebuild the number.
- Ask for the range and for what is left out, such as hardware, training or water.
The tools comparison sets these out option by option, and the Scope 3 and CSRD guide shows where the line goes in an inventory.
Where does SOMA AI fit, and what does it cost?
SOMA AI publishes the open SAEF factors, a free calculator and a paid report. SOMA AI estimates and does not measure, since AI providers do not supply measured data for a customer's usage. The method paper was accepted for publication in Sustainable Production and Consumption. The report starts from EUR 3,000 excluding VAT at a fixed price scoped on a short call, with details on the AI footprint product page. SOMA AI has an interest in you choosing it, so treat this section as a vendor description. If a free tool or your cloud dashboard answers your question, use that.
