Iberdrola España's governance and sustainability system

A comprehensive and market-leading regulatory framework

Learn about Iberdrola España’s Governance and Sustainability System, which is its internal system of rules and is made up of its own rules and policies based on the Purpose and Values of the Iberdrola Group, as well as other Group-level compliance rules that have been approved by Iberdrola, S.A. and adopted by Iberdrola España.

In the performance of its responsibilities and the exercise of its decision-making power, Iberdrola España, S.A.U. (the “Company” or “Iberdrola España”) has approved its own set of internal rules, referred to as the Governance and Sustainability System.

The Company’s Governance and Sustainability System was created as an organised internal system of rules for the first time on 11 July 2014, adopting the Group-level corporate policies and other internal regulations approved by Iberdrola, S.A., in its capacity as the holding company of the Iberdrola Group, of which Iberdrola España is a part, and which were therefore applicable thereto. 


Since then, the Company’s Governance and Sustainability System has been constantly evolving in parallel with the development of Iberdrola España and its controlled companies, such that the Company’s own specific regulations now go far beyond those adopted from Iberdrola, S.A.

In accordance with the foregoing, Iberdrola España’s Governance and Sustainability System is made up of both specific rules approved by the competent bodies of the Company and rules, foundations, policies and principles approved by the Board of Directors of Iberdrola, S.A. in its capacity as a holding company and which, in view of the applicability of these regulations to the Iberdrola Group as a whole, the Company has adopted as its own and incorporated into its Governance and Sustainability System.

This regulatory framework is structured into four books:
 

  • (i) an introductory book, which includes the Ethical and Basic Principles of Governance and Sustainability of the Iberdrola Group as well as the Purpose and Values of the Iberdrola Group.
  • (ii) book one, which includes the By-Laws and the rules governing its corporate organisation.
  • (iii) book two, with the Corporate Policies approved by the Board of Directors and grouped into four blocks: transparency and good governance; human and social capital; natural capital and sustainable value chain.
  • (iv) book three, which contains a robust regulatory framework relating to internal audit, risk management and corporate control, as well as compliance. 

Iberdrola España develops its strategy in accordance with a purpose and certain values to which all of the entities and persons forming part of the Iberdrola Group are committed, the common denominator of which is the achievement of the corporate interest and the social dividend, within the framework of its firm commitment to sustainability. 

It has an equally firm commitment to unwavering vigilance and the punishment of acts that are illegal or contrary to law or the Governance and Sustainability System, which is expressed in the approval of a range of Compliance rules, notably the Code of Conduct for Directors, Professionals and Suppliers, which is intended to ensure that the conduct of the Company, its professionals and its value chain is in accordance with ethical principles, the law and the Governance and Sustainability System.
