CBA collaborates with the Global Sustainable Enterprise System (GSES). The GSES platform is an online measurement system for sustainability. It allows companies to measure, monitor and certify their sustainability performance and immediately see areas that should be improved.

All measurements are based on internationally accepted norms and standards. The universally recognised certifications, initiatives and quality marks are guaranteed up-to-date and are consistently reviewed and validated by external objective auditors in 77 countries.

In addition to an annual internal check, CBA’s policies and progress are independently checked by a GSES auditor.
