Verification
ISO 14064-1 ve ISO 14064-2 Verification Process
Corporate Carbon Footprint Verification Service and Greenhouse Gas Reduction Validation and Verification Services
1. Preparation for Verification
Obtaining Information and Documents Related to Verification from the Company/Client/Facility and Making Notifications
In accordance with the approved Verification Contract, the Verification and Validation Operations Coordination Unit contacts the responsible personnel of the Greenhouse Gas Inventory Team of the Company/Client/Facility regarding Greenhouse Gas Monitoring and Reporting. It requests the Greenhouse Gas Inventory Plan, the Greenhouse Gas Declaration, and other necessary information and documents (other than the annexed documents) through the “Verification Information and Document Request Form.” The Coordination Unit also requests and reviews relevant Information Management Procedures, Calculation Documents, and similar materials.
2. Planning of the Strategic Analysis
Selection, Impartiality Assessment, and Appointment of the Verification Team
According to the ISO 14064 and Other Specific Greenhouse Gas Programs Pricing Instruction, if no verification service has been provided to the client/company/facility within the last two years, an on-site Strategic Analysis is mandatory.
For facilities where no on-site Strategic Analysis is to be conducted (as specified in the contract), only the office phase of the Strategic Analysis will be performed, and the Strategic Analysis Form will be completed.
Notification and Approval of the Strategic Analysis and Verification Team
If no objections are raised by the Client/Company/Facility regarding the team members listed in the Strategic Analysis & Verification Team Notification Form, it is deemed that the Strategic Analysis and Verification Teams are approved and that no commercial relationship or conflict of interest exists.
In case of any changes to the team members, a revised Strategic Analysis & Verification Team Notification Form is sent via e-mail to the GHG Monitoring and Reporting Officer of the Client/Company/Facility for approval and declaration of impartiality.
Transfer of Information and Documents to the Strategic Analysis Team
The Verification and Validation Operations Coordination Unit provides the verifier or lead verifier assigned to perform the Strategic Analysis with the necessary company-specific information and documents. The verifier or lead verifier reviews these materials, and if any information or documents are missing, requests them again through the Verification Information and Document Request Form by contacting the responsible personnel.
Scheduling of the Strategic Analysis
The verifier or lead verifier assigned to the Strategic Analysis prepares the schedule for both the office and on-site phases, and jointly determines the date of the on-site Strategic Analysis with the Client/Company/Facility.
3. Conducting the Strategic Analysis
Office Phase of the Strategic Analysis
To prepare for the on-site phase, the verifier or lead verifier examines the company’s information and documents, the Greenhouse Gas Inventory Plan, and the Greenhouse Gas Declaration for the relevant monitoring period. The verification scope of the Client/Company/Facility is assessed. After obtaining the necessary information, the relevant sections of the Strategic Analysis Form are completed, and preparations for the on-site analysis are finalized.
On-Site Phase of the Strategic Analysis
During the on-site Strategic Analysis, the verifier or lead verifier collects and reviews all relevant information and documents related to the activities of the Client/Company/Facility in order to determine the nature, scale, and complexity of the verification activities.
Identification of Data Flow Activities and Potential Verification Risks
This step is carried out to understand the facility’s data flow processes, activity data, and emission sources, and to identify potential risks that may arise during verification.
Even if no on-site Strategic Analysis is performed, Data Flow Activities must still be defined during the office phase, drawing from the previous year’s verification experience.
Preparation of the Strategic Analysis Result Evaluation Report and Completion of the Strategic Analysis
Before the completion of the Strategic Analysis, the lead verifier prepares the Strategic Analysis Result Evaluation Report to enable more effective verification planning.
4. Preparation for Verification
Review and Evaluation of the Verification Team’s Competence
Based on the pre-contract evaluation and the information obtained during the Strategic Analysis, the Verification and Validation Operations Coordination Unit makes any necessary team changes. The Coordination Unit appoints an Independent Review Team (IRT) composed of a lead verifier, verifier, and technical expert of equal competence but independent from the verification team.
The appointed members of the Verification and IRT Teams sign the Verification Team Appointment–Contract Form, confirming that they have no commercial relationship with the Client/Company/Facility that could compromise impartiality.
Transfer of Information and Documents to the Lead Verifier
The Coordination Unit provides the Lead Verifier with all previously obtained information and documents, as well as the results of the Strategic Analysis, necessary for performing the verification activities.
5. Verification Planning
Contribution Analysis
Using the information from the Strategic Analysis and the company, the Lead Verifier conducts a Contribution Analysis to determine which data flows and measurement points contribute most significantly to estimated emissions, thus requiring greater verification focus.
Assessment of Verification Risks
Following the identification of potential verification risks for each data flow and process step during the Strategic Analysis, all potential risks are evaluated considering the related control activities.
Verification Planning
To conduct verification effectively, a competent team must develop an appropriate Verification Program and Testing Plan.
Verification planning begins with an effective Strategic Analysis. For each data flow at the facility, process and control activities are identified. The verification team plans and performs its verification to assess the effectiveness of control activities and compliance with defined procedures.
Preparation of the Verification Program
Based on the Contribution Analysis and Verification Risk Assessment, the Lead Verifier prepares the Verification Program, which defines the scope, nature, and timing of verification activities.
Preparation of the Data Sampling Plan
The Lead Verifier prepares the Data Sampling Plan in accordance with ISO 14064-1 and the Risk Assessment results, applying analytical procedures and data analysis for verification purposes.
Notification of the Verification Field Test Plan to the Facility
Before visiting the facility, the Lead Verifier agrees on the Verification Field Test Plan with the GHG Monitoring Officer of the Client/Company/Facility. The agreed plan is sent to the facility at least one week in advance.
6. Conducting the Verification
During process analysis, the verification team must collect sufficient evidence to form a reasonable assurance verification opinion by performing various checks and tests.
The verification team examines whether the facility’s Greenhouse Gas Inventory Plan and Information Management Procedures are implemented and up-to-date.
Data flows and control activities are evaluated according to the defined procedures. Any data inconsistent with expectations or showing significant deviations are re-evaluated statistically to assess their effect on verification risk.
Data Verification
During field sampling, the appropriate sampling method is selected per the Data Sampling Method Instruction, and records are traced from emission calculations to primary data sources. The verification team reviews how data are monitored both in office and field stages.
Uncertainty Assessment
The verification team evaluates the uncertainty of all measuring instruments in accordance with the Measurement Equipment Control and Uncertainty Assessment Instruction, records measurements in the Measurement Uncertainty Calculation Form, and verifies the accuracy of instruments on-site.
Collection of Verification Evidence and Creation of Verification Findings
During verification, if clarification is required on certain issues, the verification team requests explanations via the Feedback Form, which is sent to the Client/Company/Facility by e-mail.
Identification and Correction of Non-Conformities, Misstatements, and Improvement Recommendations
Responses to Feedback Forms and findings identified during verification are documented in the Non-Conformities, Misstatements, and Improvement Recommendations Tracking Form. These are submitted to the Lead Verifier for approval before being communicated to the facility.
7. Final Review and Preparation of the Verification Report
The Verification Report is first drafted in Word format, and all non-conformities and findings are corrected therein. The Lead Verifier reviews and finalizes the report in printable format.
When forming the verification opinion, the Lead Verifier considers:
If no significant non-conformities or misstatements exist in the GHG Declaration, a Reasonable Assurance Verification Opinion is issued.
If significant non-conformities or material misstatements are present, an Adverse Verification Opinion is issued, specifying the non-conformities and misstatement amounts.
In cases of adverse opinions, a conservative estimated emission value is also indicated.
Once the report and opinion are finalized, they are sent to the Independent Review Officer for review.
8. Independent Review and Completion of Verification
The Verification and Validation Operations Coordination Unit appoints the Independent Review Team (IRT) using the Verification Team Appointment–Contract Form. Members confirm impartiality by signing the form.
.
The Independent Review Lead Verifier has the authority to objectively review and, if necessary, reject the draft verification report and internal documents..
.
Following a positive independent review, the finalized Verification Report is printed and the necessary annexes are prepared by TMGD A.Ş. personnel. The approved Greenhouse Gas Declaration is then sent to the Client/Company/Facility together with the Verification Report.
