Welcome to GHG Analytical


About Us

GHG Analytical is a California Air Resources Board (CARB) Accredited Verification Body. Our verification team draws on a wealth of experience in engineering, laboratory analysis, auditing, and emissions monitoring technology in the energy, oil, gas, manufacturing, refinery and electricity sectors. Our employees and parent organization, TEC Inc., have been providing environmental consulting and engineering services to Fortune 500 companies in California and the United States for 25 years.

  • We work with regulators to meet government goals while saving organizations time and money; our proprietary monitoring technology has saved national automobile fleet owners 90% of their operating costs for mandatory air-quality monitoring obligations.

  • Over two decades of experience in analogous fields, such as engineering calculations, environmental consulting, air monitoring regulations, and the energy sector.

  • Experienced verification team led by ARB accredited lead verifiers in every category except cement. 

  • One of the few verification bodies with a dedicated legal team that understands the rules and what facility operators must do to follow them.

  • In-house developed monitoring instrumentation and extensive experience with Continuous Emissions Monitoring Systems (CEMS); we can work with your monitoring systems already in place, or create an ARB-approved direct source sampling regimen. Whether you need a verification opinion or an emissions data report, our monitoring technology ensures accuracy and efficiency.


The primary goal of any verification is accuracy and integrity. Beware of competitors that will promise a positive verification opinion; there is no penalty if your reports cannot be verified as accurate, so long as steps are taken to ensure future verifiable reports.

Our goal is to make your life easier while accurately fulfilling your regulatory obligations. Contact us today, and we will tour your facility and provide you with a competitive quote for our services.
