Invoices in, an audit-ready reduction plan out.

Scope 1 and 2 are arithmetic. Scope 3 is chasing suppliers for numbers they do not have in a format nobody agrees on, which is why most reduction plans quietly stop at the factory gate.

Zoru Earth takes an activity described in plain English, or an invoice as a file, and parses the emissions out of it. Automated supplier outreach keeps Scope 3 current instead of annual. What comes out the other end is a reduction plan an auditor will accept.

It runs across UK and overseas operations, which is the version of this problem that actually bites: multiple sites, multiple currencies, multiple grids.

The GHG Protocol splits emissions into three scopes: what you burn directly, what you buy as energy, and everything else in the chain either side of you. The first two are arithmetic against a meter reading. The third is most of the footprint for most organisations, and it is the one that comes from other people’s data.

That is why provenance matters more than precision. A total nobody can trace is worth less than a slightly rougher one where every line says where it came from: this invoice, this supplier response, this factor, on this date. When an assurance provider asks how a figure was reached, the answer has to be a record rather than a recollection.

Operating across borders makes the same point harder. Multiple sites, multiple currencies and multiple electricity grids mean the same activity carries a different footprint depending on where it happened and when, so the working has to hold that context rather than flatten it into one average.
