About GreenCircle Certification

GreenCircle Certified, LLC was established to ensure specificity in third-party certification after encountering many unsubstantiated claims in the marketplace. Since 2009, GreenCircle has offered forward-thinking companies a competitive advantage by providing specific, third-party certification of environmental claims. GreenCircle's rigorous evaluation process provides independent verification that claims of sustainable aspects of products and operations are valid. Manufacturers, suppliers, regulators, occupants, and consumers can be assured that products labeled with the GreenCircle Certified mark have been thoroughly assessed and their claims verified to applicable standards.

As today's consumers become more informed, there is an increasing demand for honesty and transparency from potential suppliers. Third-party certification demonstrates that a product or operation is in compliance with its sustainability claim. GreenCircle certification helps establish brand integrity and develop consumer confidence, which is key to building your brand in the current marketplace.
