Lead GHG Verifier Training for Saudi Aramco | DEISO Case Study

From Internal Practitioners to Lead GHG Verifiers: Building Enterprise-Grade Carbon Governance Capability for Saudi Aramco

---

Executive Summary

DEISO delivered a five-day, intensive “Lead GHG Verifier Professional Training Program” in Tokyo for a specialized team from Saudi Aramco. The program addressed critical capability gaps in emissions calculation, verification, and reporting across Scopes 1–3. Through a structured, hands-on approach aligned with ISO 14064 and GHG Protocol standards, participants transitioned from operational practitioners to verification-ready professionals capable of leading internal GHG assurance processes.

Client Profile

• Organization Type: Global Integrated Energy Company
• Region: Saudi Arabia
• Team Profile: Environmental & Sustainability Professionals
• Capability Level: Intermediate → Advanced (Verification Track)

---

Strategic Challenge

Despite strong operational expertise, the client team faced several structural challenges:

• Fragmented understanding of Scope 1–3 emissions accounting
• Limited exposure to verification methodologies and assurance frameworks
• Inconsistent application of ISO 14064 requirements
• Lack of internal capability to lead verification-ready reporting processes
• Difficulty in handling complex Scope 3 categories and emission factor selection

These gaps posed a risk to:

• internal audit readiness
• regulatory alignment
• external disclosure credibility

---

DEISO Intervention

DEISO designed and delivered a 3-in-1 integrated professional program, combining:

1. GHG Emissions Calculation (Scopes 1–3)

• Full lifecycle accounting across direct and indirect emissions
• Structured Scope 3 categorization and boundary definition
• Emission factor selection logic using global databases

2. GHG Verification (ISO 14064-3 Aligned)

• Verification planning and risk-based assessment
• Data validation techniques and audit trail development
• Identification of material misstatements and inconsistencies

3. GHG Reporting (ISO 14064-1 & GHG Protocol)

• Structuring compliant GHG inventories
• Reporting frameworks aligned with international disclosure standards
• Integration of Scope 3 Calculator tools for indirect emissions

👉 The program was engineered not as training, but as a capability-building system for internal verification leadership.

Technical Execution

The program was delivered over 5 full business days (40 hours) and included:

• Hands-on Scope 1–3 modeling using Excel-based frameworks
• Application of GHG Protocol Scope 3 calculation tools
• Step-by-step verification simulation exercises
• Structured walkthrough of ISO 14064 Parts 1, 2, and 3
• Cross-industry analytical exercises to strengthen methodological adaptability

Real-World Case Studies Applied

• Oil & Gas: Upstream and operational emissions modeling
• Chemical Industry: Methanol production lifecycle emissions
• Electronics: Smartphone manufacturing and supply chain Scope 3 complexity

Participants worked directly on these cases to:

• apply boundary setting
• select emission factors
• validate datasets
• prepare verification-ready outputs

---

Measurable Outcomes

By the end of the program, participants achieved:

• Full Scope 1–3 calculation capability across multiple industries
• ~65% improvement in emission factor selection accuracy
• Significant reduction in calculation and reporting inconsistencies
• Ability to independently structure ISO 14064-compliant GHG inventories
• Capability to perform internal pre-verification checks and validation workflows
• Enhanced confidence in handling complex Scope 3 categories (Category 1–15)

---

Strategic Value for Participants

Participants transitioned from:

Data handlers → Verification-capable professionals

This enabled:

• Internal leadership of GHG verification processes
• Reduced reliance on external consultants for data structuring and validation
• Improved readiness for:
  • ESG disclosures
  • carbon reporting frameworks
  • third-party assurance

---

Why This Matters

Most GHG training programs focus on theory or tool usage.

This program delivered:

• verification-grade capability
• standards-aligned execution
• real-world application across industries

👉 The result is not just knowledge — but operational readiness for enterprise carbon governance.
