Environmental Services, Inc., (ESI) is accredited by the American National Standards Institute (ANSI) under ISO 14065:2013 for greenhouse gas (GHG) validation and verification bodies, including: ISO 14064-3:2006, ISO 14065:2013, and validation/verification of assertions related to GHG emission reductions and removals at the project level for Land Use and Forestry (Group 3). ESI is also an Accredited Offset Verification Body of Offset Project Data Reports for the California Air Resource Board. Our accreditations underline and reinforce our ability to meet the stringent requirements for independent, third-party validators and verifiers of the leading GHG programs.

ESI first established their Forestry, Carbon, and GHG Services Division in 2007. Since then, we have completed numerous validation and/or verification projects across the United States and around the world. The GHG validation/verification services provided by ESI ensure that GHG emissions reduction/removal assertions within defined projects are accurate, transparent, and credible.

The ESI philosophy and technical approach stresses experience, competence, communication, and above all, responsiveness to the needs of our clients. We are confident that we can provide additional value to you and your company through the successful validation and verification of your GHG reduction/removal projects.

In order to ensure that your project is validated and/or verified correctly and with complete transparency, ESI has developed a number of guidelines and policies designed to protect and promote the third-party relationship as a validator/verifier. Read our Guidelines & Policies>>>
