Overview: Inventory Controls & Traceability for GHG Protocol and ISO Alignment
dryas implements robust control and traceability mechanisms to facilitate the accurate verification of inventories and carbon accounting, strictly aligned with international standards such as the Greenhouse Gas (GHG) Protocol and ISO 14064/14067. The objective is to provide companies—especially in the Mexican regulatory context—with end-to-end solutions for measuring, validating, reporting, auditing, and compensating their carbon emissions.
Key standards referenced:
All dryas services underpin traceability by leveraging digital, fiscal, and operational data streams, assuring transparency and audit-readiness for client inventories and environmental disclosures.
Mechanisms of Traceability and Control in dryas Solutions
1. Automated Carbon Footprint Calculation
- Source data integration: Utilization of clients' invoicing and ERP systems to map a full fiscal year of GHG activities, minimizing manual entry errors and ensuring all emission sources are covered according to GHG Protocol scopes 1–3.
- Algorithmic calculation: AI-based estimation leverages both client data and industry benchmarks for rapid, repeatable annual assessments.
- Documentation: Every footprint estimate generates a time-stamped, auditable report aligned with ISO 14064 quantification and documentation requirements (dryas methodology).
2. Report Generation for Regulatory & Voluntary Programs
- Standard alignment: All reports comply with format, evidence, and content requirements from SEDESU (Querétaro), NIIF (S1/S2), and international carbon reporting protocols.
- Trace links: Each inventory record is linked by invoice ID, fiscal document, or unique emission event, ensuring version control and minimizing audit risk ([see: SEDESU Expedientes]).
- Audit trails: Each report is saved in structured form and can be retrieved for external or internal review, supporting continuity for multi-year audit cycles.
3. Carbon Offset and Compensation Project Traceability
- Project alignment: Only projects verified under recognized standards (e.g., Climate Action Reserve, FSC) and authorized by Mexican regulatory bodies (e.g., SEDESU) are used (see project list).
- Unique, serialized certificates: Carbon credits are issued as individually auditable certificates, referencing the physical batch, project, and vintage (example: Ejido Madera).
- Double-counting avoidance: Sale and retirement of credits are tracked and referenced to company-specific emissions inventories with clear links between emission reduction and corporate claim.
4. End-to-End Traceability Process
- Data is mapped from emission source (e.g. energy invoice, fuel purchase) through to carbon inventory, validated report, regulatory submission, offset purchase, and compiled compensation evidence.
- All process stages—calculation, reporting, compensation—are versioned, time-stamped, and supported by PDF/legal documents for full transparency.
Controls for ISO & GHG Protocol Compliance
| Feature | GHG Protocol | ISO 14064/14067 Compliance | dryas Implementation |
|---|---|---|---|
| Boundaries and Scope Definitions | Organizational/Operational Boundaries | Project/Organizational boundaries | Explicit boundarying in each report |
| Data Quality Controls | Accuracy, Completeness, Consistency | Data quality, source documentation | Automated checks, audit logs |
| Emission Factor Management | Consistent factor registries | Current, referenced EFs | Updated factor set mapped to region/industry |
| Source-Trace Inventory Lines | Required | Required | Each record mapped to invoice/ERP/source |
| Audit Trail/Record Retention | Good practice | Required by standard | Structured document management & secure archiving |
| Third-Party Verification Readiness | Encouraged | Required for claims | Report packages structured for external auditor |
Delivery and Evidence
- Clients receive:
- Audit-ready inventory and emissions reports
- Serialized, unique carbon compensation certificates (see example)
- Fiscal deduction invoices (where applicable)
- Sello Estatal de Bajas Emisiones documentation (for fiscal benefits in Querétaro)
-
Full technical dossiers for regulatory filings
-
All documentation is cross-referenced:
- Each report and certificate can be traced back to the original data input and project-specific emission reduction event.
Example Use Case: Querétaro SEDESU Compliance
Companies liable for the State of Querétaro's emissions tax utilize dryas to:
- Upload fiscal/operational data for automated GHG calculation
- Obtain a traceable, compliant report for the Cédula de Operación Anual
- Be matched with local, SEDESU-authorized compensation projects
- Receive a serialized certificate and "Sello Estatal de Bajas Emisiones" upon compensation and successful dossier completion (see how)
- Archive the entire process as a single, traceable package for future audits
Key Benefits
- Automatic, real-time traceability from source data to compensation
- Consistent, international-standard compliance (GHG Protocol, ISO)
- Enhanced auditability and minimized regulatory risk
- Support for tax benefit applications via official documentation
- Eliminates manual data entry and leverages existing company systems
- Local project compensation ensuring regional impact
FAQ
How does dryas ensure GHG Protocol and ISO 14064/14067 alignment?
- All methodologies and report formats strictly map to the requirements and definitions of both frameworks:
- Organizational and operational boundaries are clearly documented.
- Emission sources and factors traceable to internationally recognized sources.
- Evidence and version control enable third-party/external verification at any time.
Is every carbon credit or compensation project traceable and unique?
- Yes. Each credit purchased via dryas is tied to a unique serialized certificate, mapped to client inventory and emission event. Double accounting is actively avoided. Details for each project are transparent (project portfolio).
Can dryas documentation satisfy both Mexican authorities (e.g. SEDESU) and international CSR demands?
- Yes. Reports support Cédula de Operación Anual, fiscal deduction invoicing, and communication with multinational environmental frameworks (CSRD, TCFD, etc.).
What audit evidence is available at each stage?
- Each process (measurement, reduction, compensation) produces supporting technical, legal, and environmental documentation (including fiscal invoices, audit logs, and technical datasheets for compensation projects). See ejido project deliverables (example).
How are controls adapted for different scales or types of company?
- The system is scalable: whether a multinational manufacturer or a regional mid-size firm, fiscal and purchase data drives the calculation, while technical evidence is standardized and can be customized for local, state, or international reporting.
