Verification and Accreditation Requirements

Third-party verification of Emissions Report (only applicable to taxable facilities)

Verification involves an independent and objective assessment of the accuracy of the Emissions Report based on the implementation of the Monitoring Plan. The registered corporation is required to engage an NEA-accredited third-party verifier to verify each taxable facility’s Emissions Report annually, before submitting the Emissions Report to NEA by 30 June of the year following the end of each reporting period. Only information relating to reckonable greenhouse gas (GHG) emissions is subjected to third-party verification.

Verification Report submission and templates

Accredited verifiers shall use the following templates provided by NEA to prepare for the conduct of verification and the final verification report:

  1. Notice of verification template
  2. Verification plan summary template
  3. Verification report template

The templates can be downloaded from the Emissions Data Monitoring and Analysis (EDMA) system here.

Application for accreditation to conduct verification

Any Singapore registered company that wishes to provide third-party verification services in relation to the Carbon Pricing Act (CPA) shall be accredited by NEA. Accreditation involves an independent assessment by NEA on whether a verification company has the competence to carry out the verification of GHG emissions reporting in line with the CPA and its accompanying regulations.

NEA will inform the verification company of the outcome of the application within 30 days of receiving the complete application. Verification companies engaged by facilities to conduct verification on their Emissions Report shall complete the verification and submit the verification report to the facility and NEA before 30 June of the year following the end of each reporting period.

The verification company is required to read the Verification and Accreditation guidelines in detail and assess the company’s capabilities to meet the accreditation requirements before making an application to NEA. The application form can be found here.
