Frequently Asked Questions

  • About Verification and Training Programs
    Verification improves the consistency, comparability, and credibility of Higg Index data. It also reduces the need for multiple, proprietary audits for facilities so that resources can be effectively used in other areas, such as performance improvement. By measuring and verifying sustainability performance, the industry is able to identify and address hotspots, drive industry transformation, and achieve transparency. Through collectively verifying sustainability data, Cascale members and Higg Index users can address the urgent, systemic challenges together.
