Emission factors are only as useful as your confidence in them. We solve the provenance problem that every carbon accountant faces.
Every factor from every source mapped to one consistent structure — activity, region, year, unit, methodology. No more manual mapping between DEFRA and NGA categories.
Each factor links directly to its originating document, version, and publication date. Generate audit-ready citations in one click — built for CSRD, ISSB, and NGER reporting.
See exactly when a factor changed, why, and what it was before. Never lose track of which version your disclosure used. Comparable to git, but for carbon data.
Query any factor with a simple REST call. JSON responses, OpenAPI spec, Python and curl examples. Integrate directly into your sustainability tool or spreadsheet workflow.
Source publications are monitored continuously. When NGA or DEFRA release a new version, factors are updated, diffed, and published — with clear verification timestamps.
NGA (Australia), DEFRA (UK), GHG Protocol, EPA (US), and IEA datasets — normalised and cross-referenced. One query. All sources. Globally applicable.
Emission factor releases, regulatory changes, and industry developments — curated for practitioners.
We're building the infrastructure layer carbon accounting has been missing. Join the waitlist for early API access, free developer tier, and a say in what we build first.
Takes 30 seconds. No spam, ever.
We'll be in touch before launch.
Thanks for helping us build this right.
