Our contracting processes are executed in accordance with applicable local legislation and are based on criteria that promote sustainable development and the principles of free competition, equal treatment and non-discrimination, and transparency. The above, through clear references to codes of conduct, including the Group's Human Rights Policy, the Code of Ethics, the Zero Tolerance Plan for Corruption and Global Compliance Programs.

The Company's acquisition procedures are designed to ensure quality of service with full respect for the principles of economy, effectiveness, timeliness, equity and transparency, being reviewed continually to ensure alignment with Company policies.

In addition to meeting the requested quality standards, the services of our suppliers must also go hand in hand with the adoption of best practices in terms of Human Rights and working conditions. For Enel Chile, it is of fundamental importance to evaluate our suppliers in terms of respect for human dignity, non-discrimination, inclusion, freedom of association and collective bargaining, safety and health at work, environmental responsibility, impact on communities, dissemination of principles relating to respect for Human Rights throughout the value chain, and respect for privacy.

Together with our suppliers, we work to define new metrics and promote co-innovation towards decarbonization and the circular economy, which has a positive impact on both production processes and purchasing techniques. For the most strategically important goods categories, we require global product environmental declarations to objectively quantify, certify and report the impact of the entire acquisition life cycle (i.e. water consumption, CO₂ emissions, impact on the ground, etc.).

ISO 14001 certification or equivalent is always required for product groups that are considered high environmental risk, and on-site audits of our contractors are also carried out.
