Oregon Third Party Verification Program

Division 272 of the Oregon Administrative Rules was adopted in May 2020 to establish third party verification requirements for verification of data submitted to the Greenhouse Gas Reporting and Clean Fuels Programs. Independent third-party verification improves data reliability and provides the necessary assurances that people doing business in Oregon are accurately calculating emissions and correctly meeting DEQ reporting requirements. The data collected by these programs is considerable and will continue to grow in breadth, depth, and importance.


Interested in becoming an approved verifier or verification body in Oregon?

Individuals and businesses interested in providing verification services in Oregon must receive approval from DEQ. Verifiers work with regulated parties to ensure that the data they submit to DEQ conform with the regulations. DEQ staff are currently developing the application, training and approval process.

A prerequisite for approval is accreditation through the California Air Resources Board (CARB) and/or the American National Standards Institute (ANSI). For more information about this process, please read the PDF below:
