Transparent by design
Every number on your dashboard links to the inputs that made it and the cited factors behind it.
- DESNZ emission factors — the same UK government figures used in official greenhouse-gas reporting. Source cited on every result.
- Pinned calculations — your historical results are locked to the factors in use when you entered them. New factor releases never silently change old data.
- Browse the catalogue — every formula and every emission factor is publicly readable without signing up.
- Household data stays yours — no selling, no ads. Invite housemates to share one account.
