Methodology

How GreenDsk reports are built.

Transparent ESG reporting, built around data quality and clear boundaries. This page summarizes how GreenDsk calculates Scope 1 and Scope 2, how it handles Selected Scope 3 & Readiness, how data quality and buyer-readiness are determined, and what GreenDsk explicitly does not claim.

Scope 1 & 2 calculation basis

Scope 1 emissions are calculated from on-site fuel combustion and owned vehicles using emission factors maintained in the GreenDsk calculation engine. Scope 2 is reported on a location-based basis (grid average) and, where supplier-specific contractual instruments (RECs, PPAs, green tariffs) are provided, on a market-based basis. Each calculation records the result, source, confidence, and factor version used.

Selected Scope 3 & Readiness

Selected Scope 3 & Readiness helps screen all 15 Scope 3 categories, calculate business travel where data is provided, and document readiness gaps and next data steps for other relevant categories. Each category is marked Relevant, Not relevant, Unsure, or Not enough data yet, with a status of Calculated, Readiness only, or Not included, and an explicit Included in disclosed emissions total: Yes/No.

Calculated Selected Scope 3 currently includes business travel where data is provided. Other Scope 3 categories are shown as readiness screening, not as calculated emissions, and are not part of the disclosed emissions total. This is not a complete Scope 3 inventory.

Data quality framework

Every input field captures a source ("Known" vs "Estimated") and a confidence level (High / Medium / Low). The report rolls these into a single Data Quality (DQ) grade and shows the underlying breakdown. Buyers can see exactly which fields are evidence-backed, which were estimated, and which were documented as unavailable.

Buyer-readiness status

Each report is assigned a buyer-readiness status — Buyer-ready, Needs review, or Not ready — derived from validation checks and the data quality score. Buyer-readiness is GreenDsk's internal assessment of whether the disclosure is suitable for common buyer review. It is not a third-party rating, assurance opinion, or guarantee of buyer acceptance.

Versioning & reproducibility

Each report records the methodology version and calculation engine version used at the time of generation. Regenerating a report with new inputs produces a new versioned snapshot; prior versions remain accessible for buyer comparison.

Review limitations and what GreenDsk does not claim

  • Reports are based on self-reported facility data. GreenDsk reviews for completeness and reasonableness but does not independently verify source documents.
  • GreenDsk is not an audit, assurance, or certification body.
  • GreenDsk does not provide legal or regulatory advice, and is not a substitute for filings required of public companies or covered entities.
  • Full CSRD, ESRS, ISSB, or SEC programs require additional process, controls, and assurance that GreenDsk does not provide.
  • The Scope 3 section is a relevance and readiness assessment with selected calculations — it is not a complete Scope 3 inventory or complete value-chain emissions accounting.
  • Buyer-readiness is an internal indicator, not a guarantee of buyer acceptance.
  • Emission factors evolve. The factor and methodology version is shown on every report.
GreenDsk reports are based on self-reported facility data and reviewed for completeness and reasonableness. They do not constitute independent third-party assurance, audit, certification, legal advice, regulatory filing, or guaranteed buyer acceptance.
