co2_graySpatial Informatics Group (SIG) brings top level expertise to carbon quantification, forest modeling, project support, documentation, monitoring and policy development. Our Carbon Offset Team has helped landowners in the development of over 8.3 million carbon offset credits on 533,000 acres under the Climate Action Reserve (CAR), California Air Resources Board (ARB) and Verified Carbon Standard (VCS). We have also developed the Forest Carbon Assessor™, an analytical tool which can assist in quickly determining a project’s feasibility by estimating carbon credits under a range of protocols from forest inventory data. We provide a full line of carbon offset services, including:

Project Assessment

  • Provide cursory or detailed estimates of marketable forest carbon credits
