Experience

Experience is the Difference

Environmental Services, Inc. (ESI) is a progressive leader in the development and provision of services within the emerging greenhouse gas (GHG), ecosystem services, third-party validation and verification and carbon sequestration markets both nationally and internationally. We maintain our position on the forefront of these emerging markets by continually working with forward-thinking clients and seeking out new projects.  Our constant drive to understand the intricacies of the rapidly changing ecosystem services and greenhouse gas markets allows us to provide expert advice and proven services to our diverse clientele.

Broad Experience and Specific Science

From the small, forest service management company to the largest timber growers in the world, and from entrepreneurs forging new technologies in carbon sequestration to City, County, State, and Country governments; ESI provides services to a wide array of commercial, governmental, and social organizations seeking to  produce creditable products and maximize their return on investment in environmental markets.

ANSI Accredited Verification and Validation

ESI is accredited by the American National Standards Institute (ANSI) under ISO 14065:2007 for greenhouse gas (GHG) validation and verification bodies.  The scope of accreditation includes ISO 14065:2007, ISO 14064-3:2006, and verification/validation of assertions related to greenhouse gas emission reductions and removals at the project level for Land Use and Forestry (Group 3). To achieve the accreditation, ESI successfully completed an exhaustive review and assessment process during which our unique ability to provide independent and impartial validation and verification of greenhouse gas emissions reductions was demonstrated. This accreditation underlines and reinforces our ability to meet the stringent requirements of the leading greenhouse gas reduction and carbon offset registries/protocols including Verified Carbon Standard (VCS), Chicago Climate Exchange (CCX), and Climate Action Reserve (CAR).

Experienced Scientists and Project Managers

We have a highly experienced group of project managers from a broad range of specializations. Our project managers are drawn from our team of talented practitioners where each individual spends thousands of hours in the field ensuring a ground-up understanding of the science, the processes, client needs, and best-practice methodologies.
