With the Carbon Pricing Act (CPA) mandating registered corporations to submit Emissions Reports annually for relevant facilities, as well as emerging grants and loans for Greenhouse Gas (GHG) reduction projects, reporting of GHG emissions is now more pertinent to the industry than ever before. In order to be a responsible business and a market leader in the industry in today’s climate, companies must put accountability into practice through transparent reporting and verification of their GHG emissions.

Industrial Smoke

TEMBUSU Asia  has a team of GHG verifiers that supports companies in such projects by providing verification services for carbon abatement in accordance with ISO 14064-3 which covers two aspects: Validation and Verification. Validation involves an analysis of carbon project data and documentation. TAC will deliver a validation opinion statement to ensure adequate GHG emission reduction against the project objective. Verification is an evidence-based approach that ensures that reported GHG emission data and information is true and fair. 

TAC upholds and maintains our impartiality which may exist between consultancy and third-party validation/verification services by continuously identifying and mitigating risks to independency arising from our activities. Read our commitment to impartiality here.

Information about validation/ verification process

Our validation/verification process starts with understanding project scope, objectives and criteria from the client during the pre-engagement stage. TAC shall ascertain the availability of resources and threat to impartiality before proceeding with the proposal submission. Upon acceptance of proposal by client, TAC moves into planning of validation/verification activities by conducting strategic and risk assessment and preparing validation/verification plan. Notice of Verification will be issued to the client prior to site or virtual audit at the end of planning stage. During validation/verification process, TAC will remotely sample data for desktop analysis prior to site or virtual audit. Finally, TAC will conclude its opinion in a report. Draft report will be reviewed prior to the issuance of the validation/ verification report and statement.
