GLJ has a 50+ year reputation built upon providing independent, accurate and reliable certification of reserves and resources for our broad clientele. Certification is becoming equally important in areas of sustainability and emissions management. As regulation continues to increase in this area, certification will increasingly become a requirement. Even when not required, an independent review of a project or report can be a valuable addition when recognized by your external stakeholders.

Our approach to certification of sustainability and emissions management initiatives and reports seeks not only to ensure accuracy but also to promote the desired operational outcome. We use our experience and expertise to confirm the product, system or service meets specifications and regulations. We then supplement that confirmation, when possible, with additional recommendations to further enhance the ability of the product, system or service to fulfill its intended purpose. Our intent is to expand your organization’s potential positive impact.
