Methods and sources

Standards, regulations and controlled datasets

Calculation methods, legal frameworks and reference datasets are versioned independently. Historical results retain the exact versions used.

Return to workspace
01No silent substitution

Missing official records remain missing. Estimates and scenarios are labelled at input and output.

02Version at calculation time

Source, edition, validity period, formula and evidence state are written into the result record.

03Separate method from law

ISO, GHG Protocol, EU rules, national methods and programme instructions remain distinct but linked.

04Evidence before assurance

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.

EUEnergy Performance of Buildings DirectiveEU-2024-1275
active

Building life-cycle GWP readiness records product quantities, data coverage, scenarios, reference period, operational energy and the applicable national calculation method.

Primary source
EUESPR Digital Product Passport readiness2024-framework
active

Readiness model only. Product-specific delegated acts determine required passport content.

Primary source
EUEU CBAM certificate prices2026-quarterly
active

Quarterly prices apply in 2026. Weekly prices apply from 2027.

Primary source
EUEU CBAM definitive period2026-definitive
active

Calculation records lock the exact price, input basis, methodology version and evidence state used at calculation time.

Primary source
EUEU Construction Products RegulationEU-2024-3110
active

Product identity, intended use, technical specification, performance information, conformity and digital information are modelled separately from the EPD.

Primary source
EUEU Deforestation Regulation2026-implementation
upcoming

The workspace records applicability, traceability, geolocation, legal-production and risk evidence. Official submission remains in the EU information system.

Primary source
EUEuropean Sustainability Reporting Standards2026-revised-adopted
pending scrutiny

Version is retained separately from earlier ESRS datasets because the delegated act is subject to parliamentary and Council scrutiny.

Primary source
EULESS low-emission steel classification referencecurrent-methodology-reference
active

Classification is not calculated unless the current controlled LESS methodology, boundary rules and assurance requirements are installed.

Primary source
EUREACH Candidate List screeningofficial-export-required
requires import

The checker only returns definitive matches from the imported official dataset. It never infers absence from an incomplete dataset.

Primary source
EUVoluntary sustainability reporting standard2026-revised-adopted
pending scrutiny

Workspace sections are evidence-oriented; authoritative datapoint imports should be refreshed once scrutiny is complete.

Primary source
GLOBALCarbon footprint of productsISO-14067-2018
active

Product carbon-footprint readiness is linked to the life-cycle study record and the exact data and impact method used.

Primary source
GLOBALConstruction-product environmental declarationsISO-21930-2017_EN-15804-A2
active

Construction EPD records preserve module scope, reference service life, product category rules and verifier state.

Primary source
GLOBALFacility greenhouse-gas inventoryworkspace-1.0
active

Factors are never hard-coded as universal truth. Every factor must carry geography, year, unit, source and version.

Primary source
GLOBALFacility greenhouse-gas inventoryworkspace-2.0
active

Factors are never hard-coded as universal truth. Every factor carries geography, period, unit, source, version and quality state.

Primary source
GLOBALFacility greenhouse-gas inventoryworkspace-3.0
active

Factors are never hard-coded as universal truth. Every factor carries geography, period, unit, source, version and quality state.

Primary source
GLOBALGreenhouse-gas inventories, projects and verificationISO-14064-series-current
active

Organisation inventories, project reductions and validation or verification are distinct data and governance objects.

Primary source
GLOBALIEA near-zero emissions steel numerical screenIEA-2024
active

The 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 source
GLOBALIndustrial decarbonisation scenarios and delivery controlsworkspace-4.0
active

Measures, interactions, capital recovery, pathway timing and delivery controls are recorded separately. Results are scenarios, not engineering guarantees or forecasts.

Primary source
GLOBALLife-cycle assessment study architectureISO-14040-2006_14044-2006
active

The workspace supports study design, boundaries, data quality and review records. It does not include a licensed life-cycle inventory database.

Primary source
GLOBALProduct life-cycle GHG accountingGHGP-Product-2011
active

The GHG Product Standard is mapped alongside ISO 14067 without merging their requirements.

Primary source
GLOBALResponsibleSteel production and claims referenceV2.1.1-current
active

Certification, progress level, product declaration and chain-of-custody claims require the current ResponsibleSteel rules and assurance process.

Primary source
GLOBALSteel site and product emissionsworkspace-4.0
active

Site, 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 source
GLOBALType III environmental declarationsISO-14025-2026
active

Programme rules, PCR, declared unit, indicator set, independent verification and publication state are separate controlled records.

Primary source
UKUK CBAM readiness2027-readiness
upcoming

Readiness and applicability only until final operational rates and all subordinate rules are loaded.
