open-climate.ai Docs
Numbers checked against the live data on
open-climate.ai brings emission factors from many publishers onto one model, with each value's unit, region, system boundary, reference year, GWP basis and licence kept beside it. These docs explain how to use those factors and how to build on them.
Factor search and the matching agent#
Two products carry the open-climate.ai name.
Factor search is the published libraries put on one model and served to everyone: the search page, the factor pages, the exports and downloads, the read API and the SQL model behind them. It answers "which factor should I use, and can I defend it". Nearly all of these docs are about factor search. What is free, and what needs an account is every gate on it in one table.
The matching agent takes a file of your own purchase or activity lines and maps each line to a factor from factor search. It answers "here is my ledger, which factors apply". It runs from the matching page, which needs no account, or from the /v1 endpoints in the API reference, which need a key. If you build software and want it inside your own product, read Integrate our MCP server into yours.
How these docs are arranged#
Five sections, one per question you might arrive with. The sidebar marks the pages that show SQL or an HTTP request; on those pages every query is folded behind a plain-language line, and a Show code switch at the top opens them all when you want the query itself.
- Your first calculationTen minutes, no account and no code: find a factor, multiply, and write down what you used.
- The dataWhere the factors come from, what we changed on the way in, and what the model guarantees.
- Factor searchFind, read, compare, cite and export a factor, on the site, over HTTP or in SQL.
- Matching agentFor software vendors: put our matching tools in front of your own users, through your MCP server.
- ReferenceLook one thing up: a term, a code list, a table, an endpoint, or what changed and when.
- API referenceEvery endpoint, its parameters and a live request you can send, from the OpenAPI schema itself.
