Standards, regulations and controlled datasets
Calculation methods, legal frameworks and reference datasets are versioned independently. Historical results retain the exact versions used.
Missing official records remain missing. Estimates and scenarios are labelled at input and output.
Source, edition, validity period, formula and evidence state are written into the result record.
ISO, GHG Protocol, EU rules, national methods and programme instructions remain distinct but linked.
Ownership, review, change history and control status are recorded before any external verification claim.
Installed methodologies
Status describes the installed source package, not legal advice.
Building life-cycle GWP readiness records product quantities, data coverage, scenarios, reference period, operational energy and the applicable national calculation method.
Primary sourceReadiness model only. Product-specific delegated acts determine required passport content.
Primary sourceQuarterly prices apply in 2026. Weekly prices apply from 2027.
Primary sourceCalculation records lock the exact price, input basis, methodology version and evidence state used at calculation time.
Primary sourceProduct identity, intended use, technical specification, performance information, conformity and digital information are modelled separately from the EPD.
Primary sourceThe workspace records applicability, traceability, geolocation, legal-production and risk evidence. Official submission remains in the EU information system.
Primary sourceVersion is retained separately from earlier ESRS datasets because the delegated act is subject to parliamentary and Council scrutiny.
Primary sourceClassification is not calculated unless the current controlled LESS methodology, boundary rules and assurance requirements are installed.
Primary sourceThe checker only returns definitive matches from the imported official dataset. It never infers absence from an incomplete dataset.
Primary sourceWorkspace sections are evidence-oriented; authoritative datapoint imports should be refreshed once scrutiny is complete.
Primary sourceProduct carbon-footprint readiness is linked to the life-cycle study record and the exact data and impact method used.
Primary sourceConstruction EPD records preserve module scope, reference service life, product category rules and verifier state.
Primary sourceFactors are never hard-coded as universal truth. Every factor must carry geography, year, unit, source and version.
Primary sourceFactors are never hard-coded as universal truth. Every factor carries geography, period, unit, source, version and quality state.
Primary sourceFactors are never hard-coded as universal truth. Every factor carries geography, period, unit, source, version and quality state.
Primary sourceOrganisation inventories, project reductions and validation or verification are distinct data and governance objects.
Primary sourceThe screen applies the IEA 2024 scrap-adjusted numerical threshold to physical production emissions per tonne of crude steel. It is not certification or a product label.
Primary sourceMeasures, interactions, capital recovery, pathway timing and delivery controls are recorded separately. Results are scenarios, not engineering guarantees or forecasts.
Primary sourceThe workspace supports study design, boundaries, data quality and review records. It does not include a licensed life-cycle inventory database.
Primary sourceThe GHG Product Standard is mapped alongside ISO 14067 without merging their requirements.
Primary sourceCertification, progress level, product declaration and chain-of-custody claims require the current ResponsibleSteel rules and assurance process.
Primary sourceSite, route and product boundaries remain explicit. User-entered data are not presented as standard-conforming unless the complete applicable method and verification requirements are met.
Primary sourceProgramme rules, PCR, declared unit, indicator set, independent verification and publication state are separate controlled records.
Primary sourceReadiness and applicability only until final operational rates and all subordinate rules are loaded.
