ISO 14064-1 Corporate Carbon Footprint Verification

WECERT provides independent verification of organization-level greenhouse gas inventories and corporate carbon footprint reports based on ISO 14064-1 and ISO 14064-3 verification principles.

ISO 14064-1 verification helps organizations demonstrate that their reported greenhouse gas emissions, boundaries, activity data, emission factors, calculations, assumptions, and supporting evidence have been independently reviewed against defined criteria.

UNDERSTANDING GHG VERIFICATION

What Is ISO 14064-1 Verification?

ISO 14064-1 specifies the requirements for quantifying and reporting an organization’s greenhouse gas (GHG) inventory. Independent verification, carried out in accordance with ISO 14064-3, evaluates the reliability, completeness and material correctness of the reported GHG information against agreed criteria.

Verification provides greater confidence in your GHG data, supports transparent reporting, and strengthens your credibility with stakeholders.

Reporting vs. Verification

ISO 14064-1 • Quantify & report
ISO 14064-3 • Independently verify

THE VALUE OF INDEPENDENT VERIFICATION

Greater confidence in your corporate carbon footprint data and sustainability disclosures.

Who Needs ISO 14064-1 Verification?

ISO 14064-1 verification is useful for organizations that need credible, independently reviewed corporate GHG information.

Companies Preparing ESG Reports

Verification supports reliable organization-level carbon data for ESG reports, sustainability disclosures, and climate-related communication.

Manufacturing Organizations

erification of GHG inventories related to production facilities, energy use, fuel consumption, process emissions, and operational activities.

Exporters and Suppliers

Verification of corporate carbon footprint information requested by international customers, supply-chain partners, and procurement bodies.

Energy-Intensive Industries

Verification for organizations with significant electricity, fuel, thermal energy, or process-related emissions.

Logistics and Transport Companies

Verification of emissions related to fleet fuel consumption, transportation operations, facilities, and purchased energy.

Corporate Groups and Multi-Site Organizations

Verification of GHG inventories covering multiple sites, business units, facilities, or operational locations.

Food and Beverage Companies

Verification of emissions from production sites, cold chain operations, energy use, fuel consumption, logistics, and support activities.

Organizations Setting Carbon Reduction Targets

Verification provides a more reliable baseline for reduction targets, decarbonization plans, and performance monitoring.

Scope 1, Scope 2 and Scope 3 in Corporate Carbon Footprint Verification

Corporate carbon footprint verification may include Scope 1, Scope 2, and relevant Scope 3 emissions depending on the reporting boundary, intended use, verification criteria, and available evidence.

Scope 1 — Direct GHG Emissions

Direct emissions from sources owned or controlled by the organization, such as fuel combustion, company vehicles, process emissions, generators, boilers, furnaces, and refrigerant leakage.

Scope 2 — Energy Indirect GHG Emissions

Indirect emissions from purchased electricity, steam, heating, or cooling consumed by the organization.

Scope 3 — Other Indirect GHG Emissions

Other indirect emissions occurring in the organization’s value chain, such as purchased goods and services, logistics, business travel, employee commuting, waste, outsourced activities, use of sold products, and end-of-life treatment.

The verification scope should clearly define which emission categories are included, which are excluded, and how the organization justifies its reporting boundary.

Searching for an ISO 14064 Certificate?

Many organizations search for an “ISO 14064 certificate” or “ISO 14064 certification” when they need formal evidence that their corporate GHG inventory or organization-level carbon footprint report has been independently verified.

In practice, ISO 14064-1 is used for preparing and reporting an organization-level GHG inventory, while ISO 14064-3 is used for verification and validation of greenhouse gas statements. Therefore, the appropriate output is usually a GHG inventory verification statement, verification report, or corporate carbon footprint verification certificate, depending on the agreed verification scope and criteria.

WECERT supports organizations that need independent verification evidence for ISO 14064-1 GHG inventories, ESG reporting, customer requirements, sustainability disclosures, tender submissions, and corporate carbon management.

Corporate Carbon Footprint Verification Process

WECERT follows a structured verification process to review the organization’s GHG inventory and supporting evidence before issuing the agreed verification output.

Inquiry and Scope Confirmation

WECERT reviews the organization, sites, reporting period, intended use, GHG inventory boundary, selected criteria, and expected verification output.

Contract Review and Planning

The proposed verification scope is reviewed, and the verification plan is prepared, including criteria, level of assurance, materiality, required evidence, verification activities, and competence needs.

Document and Data Review

The verification team reviews the GHG inventory report, calculation files, activity data, emission factors, boundary statement, assumptions, exclusions, and supporting records.

Risk Assessment and Sampling

Areas where material misstatement may occur are identified, and samples of emission sources, records, calculations, and supporting evidence are selected for review.

Findings and Corrections

Findings related to errors, omissions, unsupported data, unclear assumptions, or inconsistent calculations are communicated for correction before final conclusion.

Final Verification Output

After verification activities and final review are completed, WECERT issues the agreed output, such as a verification report, verification statement, or corporate carbon footprint verification certificate.

ISO 14064-1 Verification FAQ

Whether you are implementing a corporate Carbon Footprint verification for the first time, the following questions address some of the most common topics organizations inquire about before embarking on their certification journey.

Corporate carbon footprint verification is an independent review of an organization-level GHG inventory or carbon footprint report. It evaluates whether reported emissions data, boundaries, calculation methods, assumptions, emission factors, and supporting evidence are complete, consistent, traceable, and materially correct against the agreed criteria.

ISO 14064-1 is used for organization-level quantification and reporting of greenhouse gas emissions and removals. It supports the preparation of corporate GHG inventories and organization-level carbon footprint reports.

ISO 14064-3 provides requirements and guidance for verification and validation of greenhouse gas statements. It is used to support the independent verification of GHG inventory reports and other GHG statements.

Many clients use the phrase “ISO 14064 certificate” when they need formal verification evidence for a corporate GHG inventory. The appropriate output may be a GHG inventory verification statement, verification report, or corporate carbon footprint verification certificate depending on the agreed scope and criteria.

The verification scope may include Scope 1, Scope 2, and relevant Scope 3 emissions depending on the organization’s reporting boundary, selected criteria, intended users, and available evidence.

Typical documents include the GHG inventory report, calculation files, boundary statement, electricity records, fuel records, refrigerant records, vehicle records, emission factor references, assumptions, exclusions, uncertainty assessment, and supporting evidence.

It may not be mandatory in every ESG reporting situation, but it is strongly useful when organizations need reliable, transparent, and credible greenhouse gas information for ESG reports, customer submissions, investors, tenders, and sustainability communication.

Corporate carbon footprint focuses on the emissions and removals of an organization. Product carbon footprint focuses on the emissions associated with a specific product or service across defined life cycle stages.

The output may include a verification report, GHG inventory verification statement, or corporate carbon footprint verification certificate depending on the agreed scope, criteria, and verification conclusion.

Verification itself does not reduce emissions. However, it improves the reliability of GHG data, which helps organizations identify emission sources, improve data quality, set reduction targets, and monitor carbon reduction actions.
