Sustainable value chain
We ensure a fair, transparent and ethical value chain
At Iberdrola, we take responsibility for encouraging our suppliers to improve their environmental, social and ethical performance through initiatives that promote excellence in sustainability management.
Our suppliers are a fundamental part of the Iberdrola Group’s operations and strategic players in the transition towards a decarbonised economy. As such, they are considered business partners and a key pillar in achieving our sustainability goals. That is why we seek to ensure a fair, transparent and ethical value chain, involving our suppliers from the very first point of contact with the Group, always taking a proactive approach to their needs and supporting them in developing new capabilities.
Supplier assessment model
At the Iberdrola Group, we are committed to ensuring that 85% of our main partner companies are subject to sustainable development policies and standards by 2028. To achieve this, we have a supplier assessment model based on criteria used globally to measure corporate responsibility across three areas: environmental, social and governance.
Accordingly, we consider 43 variables to calculate the SCORE of each of our suppliers, grouped into the Environmental (40%), Social (30%) and Governance (30%) dimensions. These factors include compliance with human rights, management of risks arising from climate change, circular economy strategy and contribution to sustainable development. We also send tailored improvement plans to suppliers whose sustainability levels do not meet the required standards.
As a result, we became the first company to receive AENOR’s Sustainable Procurement Strategy certification [PDF], in recognition of our cross-cutting commitment to sustainability throughout the company’s value chain. With this recognition, AENOR has certified that the procurement processes carried out by the Iberdrola Group generate the greatest possible positive environmental, social and economic impact throughout the entire life cycle of the service or product.
Procurement and supplier management
The high volume of procurement carried out by the Iberdrola Group serves as a driver of growth in the countries where the company awards contracts, fostering their business, industrial and social development through job creation across the entire supply chain.
To ensure responsible and efficient management of the value chain, we rely on key principles that underpin our relationships with suppliers, including the following pillars:
-
Awards
We promote and recognise the excellence of our suppliers through the Global Supplier of the Year Award, which is held as a single global event every three years.
-
Dialogue and satisfaction
We are firmly committed to understanding the satisfaction levels and expectations of our supplier companies. A key tool in this regard is the Supplier Satisfaction Survey, conducted every two years, which allows us to understand suppliers’ expectations and perceptions regarding the procurement process, their relationships with the Procurement team, their communication channels and the Company in general.
-
Human rights
We promote compliance with human rights among our suppliers. We offer the online awareness module ‘Human rights and your company’, which is available to all suppliers, their employees and stakeholders.
-
Equal opportunities
We understand equal opportunities for suppliers as the procurement of goods and services from companies without distinction based on gender, race, ethnic origin or any other condition, ensuring that everyone has the same opportunities to participate in tenders and become part of our supply chain.
-
Innovation
We have a Supplier Innovation Programme aimed at promoting and accelerating the development of new products and services that address the Company’s future needs and help it respond to the challenges facing the sector.
