Emissions Data API
The FootprintLab Emissions Data API delivers verified emission factors and spend-based carbon data over a REST endpoint. This enables you to plug peer-reviewed environmental data straight into your platform, ledger, or reporting workflow.
Built for product and data teams in fintech, accounting, ESG and procurement software. Hosted in Australia, OAuth2-secured, and backed by the same peer-reviewed IELab data behind every FootprintLab dataset.
What the API does.
Four operations cover the integration: search the factor database, calculate impacts from activity data, match activities with AI, and process many queries in a single batch.
Also available: POST /calculate/batch, POST /convert-currency for spend correction, and discovery endpoints that enumerate valid field values.
What the data looks like.
Every search returns structured impact-factor records. Here's the full shape of one, and the dimensions you can filter by.
Wrapped in { num_records, records[], info }
From card transactions to Scope 3.
The API maps to Merchant Category Codes, so transaction and expense data become emissions directly, with no classification layer to build. It also speaks ANZSIC, ISAPC, NAICS and UNSPSC, so procurement, accounting and ESG teams can query in the codes they already use.
Get the price basis right.
Factors come in two price bases, so you get the exact numbers you need.
Each response includes the source, version, method and data year behind the factor, so you can verify it or cite it in a disclosure.
How to get access.
Included from the Core plan upward. Request access and we provision your OAuth2 credentials. The full reference, quickstart and Postman collection are public, so your developers can evaluate before you commit.
