Compliance system
Endesa's comprehensive Compliance system ensures adherence to all commitments and obligations toward employees, customers, suppliers, and other stakeholders.
Our greatest strength lies in the diversity and scope of our Compliance system, which integrates criminal law, anti-bribery measures, taxation, competition, and data protection. Each area is supported by a dedicated team, appropriate procedures, and specific tools that facilitate efficient and effective performance to ensure compliance in each of these fields.
Our hallmark is a cross-cutting and inclusive approach to each of these areas within the organisation. This is made possible by our various Committees: the Supervision, Competition, Risk, and Risk Coordination Committees report to the Audit and Compliance Committee, which in turn reports to the Board of Directors.
Additionally, Endesa holds AENOR certifications for the UNE 19601, UNE-ISO 37001, UNE 19602, and UNE 19603 standards. In 2024, we were also awarded the Fiscal Transparency Seal by Fundación Haz, which recognises Endesa as a leader in best practices among IBEX 35 companies in General Issues of Transparency and Fiscal Responsibility.
Compliance system

Criminal and anti-bribery compliance
Our Criminal and Anti-Bribery Compliance System is built upon regulations, policies, and periodic risk evaluation and control actions that effectively prevent criminal offences. In 2017, we became the first IBEX 35 company to simultaneously obtain UNE 19601 and UNE-ISO 37001 certifications from AENOR , which are regularly renewed and remain valid to this day.
