What is the Carbon Data / ISO Audit page for?

Two artefacts from one set of figures. The data pack is the group's consumption and activity for a reporting year — energy, fleet fuel, business travel, purchases by cost head, headcount — measured where a meter reading, a fuel-card statement or a unit on a bill exists and otherwise estimated from spend at published rates, every figure labelled which, and no emission factors applied: it is what a consultant or assessor works from. The emissions report applies the UK Government's conversion factors to the same quantities — tonnes of CO2e by scope, the SECR disclosure, the Carbon Reduction Plan dataset, the reduction plan against the target — self-prepared and marked as not independently verified. Both preview, download and issue as frozen versions. You enter: The reporting period — a whole 1 April to 31 March year for anything a verifier will accept; the page warns when it is not; On the Emissions report view: the prior-year figures the group has published, the reporting boundary, the measured returns (waste, F-gas), meter readings keyed in or imported, the reduction projects with their expected tonnes, the Carbon Reduction Plan narrative and the ISO settings; On Documents: fuel-card statements and the off-ledger evidence — service logs, waste transfer notes, utility bills, last year's carbon report; Issue a report version, and the life of the evidence link a complete pack carries. Saral fills: Every quantity from the ledger and the modules: energy spend by utility and the kWh it implies, fleet from the vehicle register and fuel spend, travel from expense claims with actual miles by vehicle type, purchases by cost head and supplier, headcount by month — each line marked measured or estimated and every rate on the Assumptions tab with its source; Emissions by scope with the factor set for the year, the measured share of the footprint and where a document would improve it most, the intensity trend, and the gap between the trajectory and the target with how much the projects cover; A proposal from the latest DESNZ workbook — what we hold against what it says, with the cited row — for a person to apply; never applied by itself; The months with no activity recorded, the materials emissions from bill lines, and the read of last year's report to prefill the baseline. It produces: The data pack as a workbook and a PDF, and the emissions report, the SECR text and the director-signable Carbon Reduction Plan as PDF and workbook, previewed or emailed; A complete pack: the report with a read-only evidence link and the supplier documents embedded, every issued version frozen and re-downloadable from Saved packs. Where the settings live: This page's own facts are set on its Emissions report view — the baseline and target, the boundary, the ISO settings, the measured returns and the projects — and the reporting period in the header; the evidence-link life is beside the downloads. The data it reads is owned elsewhere: cost heads and the chart of accounts on Accounts → Account Reports, vehicles on Fleet → Vehicle register, travel on HR → Expenses, headcount on HR → Workers. The per-order carbon estimate on Buying → Settings → Carbon Estimates is a different thing and is not read here. The page needs the carbon permission.
