Iberdrola leads S&P's Sustainability Yearbook 2025
Iberdrola leads the electricity sector in the Sustainability Yearbook 2025, produced by S&P, having received the Top 1% S&P Global CSA Score distinction. The largest European electricity company by market capitalisation has obtained the best score in the Dow Jones Best-in-Class Indices, the former Dow Jones Sustainability Index.
Sustainability Yearbook 2025 is a yearbook that includes 780 companies selected through the Corporate Sustainability Assessment (CSA) methodology of 2024, which classifies the companies analysed in a ranking by sector.
The CSA is the leading evaluation formula in its field, helping companies to establish the link between sustainability and their business strategies. It covers more than 13,000 companies worldwide and involves an annual examination of companies‘ sustainability practices and allows for comparison of companies’ performance across a wide range of industry-specific economic, environmental and social criteria. These criteria are relevant to the growing number of investors focused on sustainability and are expected to be financially relevant to their corporate success.
This leadership is in addition to the fact that Iberdrola has been included in the Dow Jones Best-in-Class Indices for 25 consecutive years, making it the only European utility to have been included in the index throughout this time.
The electricity company, one of the three largest in the world with a value of around 87 billion euros, has met the S&P requirements for inclusion in the index. It complies with an increasingly demanding methodology that includes more than 120 sections related to sustainability, distributed in three general pillars: respect for the environment, social commitment and good corporate governance.
Iberdrola is a world leader in sustainability. Once again, it has received the highest rating of ‘A List’ from CDP in the list of the world's most transparent companies on climate change, thanks to its commitment to disclosure, transparency and environmental action. In addition to the Dow Jones Best-in-Class, it is present in the main international sustainability indexes such as Moody's ESG, MSCI, Sustainalytics, ISS-ESG, EcoVadis and FTSE4Good, among many others.
Self-sufficiency and the fight against climate change
Iberdrola continues to make progress in its commitment to energy self-sufficiency and in its proactive role as an active agent in the fight against climate change. Iberdrola already exceeds 44,000 megawatts (MW) of installed renewable capacity worldwide and has an emission-free electricity production of 84%.
