GHG Verification

GHG Verification & Assurance Services

Boost the credibility of your climate claims. ECG offers limited and reasonable assurance GHG verifications to meet regulatory and investor demands.

Independent verification of your greenhouse gas (GHG) data builds confidence with regulators, investors, and stakeholders. ECG provides third-party GHG assurance services to confirm that your reported emissions are complete, credible, and aligned with applicable standards and regulatory requirements.

Levels of Assurance: Which is Right for You?

We offer two distinct levels of GHG verification to meet your organization’s risk profile, regulatory obligations, and budget.

Limited Assurance: A cost-effective review using analytical procedures and inquiry. Ideal for smaller organizations or less complex inventories.
Reasonable Assurance: A comprehensive and high-confidence audit involving site visits, detailed data testing, and stakeholder interviews.

Our GHG Verification Process

Our verification methodology follows international assurance standards and delivers transparent, actionable findings.

Planning & Scope Definition: We establish the boundary, time frame, and emissions sources to be reviewed, tailored to your inventory and reporting needs.
Document Review: We assess emissions data, calculation methodologies, and reporting processes to ensure compliance with standards such as the GHG Protocol and ISO 14064-3.
Fieldwork (for Reasonable Assurance): Includes site visits, data testing, and interviews to confirm accuracy and identify discrepancies.
Final Verification Report: We issue a clear report with a statement of assurance and recommendations to enhance future reporting quality.

Why Verification Matters

Assurance provides more than credibility—it’s a strategic investment in trust and transparency.

Strengthen Stakeholder Confidence: Validated emissions data reinforces investor, customer, and public trust.
Prepare for Regulation: GHG verification is increasingly required under frameworks like the SEC Climate Rule and EU CSRD.
Ensure Data Quality for ESG Reporting: Verified data enhances submissions to CDP, TCFD, and other voluntary reporting platforms.
