Our accreditations underline and reinforce our ability to meet the stringent requirements for independent, third-party verifiers of the leading GHG reporting regulations and voluntary programs.

ESI first received its organizational-level accreditation in 2011. Since then, we have completed numerous GHG reporting verifications under scopes such as oil and gas, manufacturing, and pulp and paper. The independent, third-party GHG verification services provided by ESI ensure that GHG emissions assertions within defined facilities 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 verification of your GHG Emissions Inventory.

In order to ensure that your emissions inventory report is 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 verifier. Read our Guidelines & Policies>>>
