GHG Protocol.
The accounting basis beneath every emissions figure on the platform — activity data, factors and boundaries, with an evidence row for each value.
The GHG Protocol Corporate Standard defines how an organisation sets its boundary and accounts for direct (Scope 1) and purchased-energy (Scope 2, location- and market-based) emissions; the Scope 3 Standard covers fifteen value-chain categories. Every figure is activity data multiplied by an emission factor, and both halves need evidence.
What the disclosures rest on.
| Disclosure area | Data required | Evidence that supports it |
|---|---|---|
| Organisational and operational boundary | Entities and facilities in scope; consolidation approach | Entity register, ownership and control records |
| Scope 1 | Fuel combusted, process and fugitive emissions by source | Fuel meters, fuel invoices, process records, refrigerant logs |
| Scope 2 | Electricity, steam, heat and cooling purchased; location- and market-based factors | Utility meters and bills, supplier contracts, energy attribute certificates, grid factors with vintage |
| Scope 3 | Activity data by category — purchased goods, capital goods, fuel- and energy-related, transport, waste, travel, use of sold products and the rest | Supplier declarations, invoices, logistics records, waste manifests, spend data as a fallback |
| Emission factors | Factor, unit, source and year for every calculation | Factor library with provenance (DEFRA, EPA, IPCC and national grid factors) |
| Base year and recalculation | Base-year inventory and recalculation policy | Base-year records, policy document, recalculation log |
From requirement to output, on synthetic figures.
Scope 1 for one facility and one month, showing both halves of the calculation.
| Requirement | Data | Evidence | Check | Output |
|---|---|---|---|---|
| Scope 1 — activity data | Diesel consumed at Facility A, May | Fuel meter reading MTR-A-014 (measured); diesel invoices INV-2605-0187 … 0193 (reported) | Meter vs invoices within 0.5 % | Litres of diesel, with two agreeing sources |
| Scope 1 — emission factor | Diesel, stationary combustion | Factor library entry: source, unit, year | Factor year matches the period; unit conversion recorded | kgCO₂e per litre, with provenance |
| Scope 1 — result | Activity × factor | Calculation lineage kept with the figure | Reviewed by the sustainability lead | 1,245 tCO₂e · PASS · Data-Trust 92 / 100 |
| Scope 2 — location-based | Electricity purchased, all facilities | Meters and bills; grid factor with vintage | Meter vs bill; factor vintage matches period | 4,753.4 tCO₂e (30-day total) |
| Scope 3 — category 1 | Purchased goods, top suppliers | Supplier declarations via evidence requests | Supplier figure vs public disclosure where available | Supplier-level figures with status |

What is in place, and what is not yet.
- Scope 1 and Scope 2 computed as activity data × factor, with an evidence row per valueDemonstrated
The KPI engines and factor library shown across this site; every value opens to its records.
- Factor library with provenance (DEFRA, EPA, IPCC, national grid factors)Demonstrated
Each factor carries its source, unit and year; the vintage used is recorded with the figure.
- Scope 3 categories 1 and 4 and supplier outreachDemonstrated
Supplier evidence is collected through the supplier portal and cross-checked against public disclosures where they exist.
- All fifteen Scope 3 categories mappedPlanned
Remaining categories are held as reported evidence; category-by-category engines are roadmap work.
- Market-based Scope 2 with contractual instrumentsPrepared
Energy attribute certificates and contracts are held as evidence and applied by the preparer; automated matching is roadmap work.
- Base-year recalculation logPrepared
Recalculations are versioned with the figures; the policy is held as a document.
Answers, at a glance.
Does EcoVeraZ follow the GHG Protocol?
Emissions figures on the platform are computed as activity data multiplied by emission factors, with boundaries, factor provenance and calculation lineage kept with each figure, consistent with the Corporate Standard and Scope 2 Guidance. EcoVeraZ is not affiliated with the GHG Protocol.
Where do the emission factors come from?
From a factor library that records the source, unit and year of every factor — DEFRA, EPA, IPCC and national grid factors — so the vintage behind any figure can be checked.
Is Scope 3 covered?
Purchased goods (category 1) and upstream transport (category 4) through supplier evidence today; the remaining categories are held as reported evidence until their engines are built.
The GHG Protocol standards are under revision by their issuers; the versions cited were current at the review date. Framework names are the property of their respective owners and are referenced for identification only. EcoVeraZ prepares evidence for disclosure and review; it does not certify compliance and does not issue assurance opinions.
