Iberdrola named the world’s most sustainable electricity company for the seventh consecutive year, according to Clean200

Iberdrola has been recognised as the world’s most sustainable electricity company for the seventh consecutive year, according to the Clean200 ranking compiled by Corporate Knights and As You Sow, which evaluates more than 8,000 companies worldwide.

Since the previous edition, Iberdrola has climbed five positions to rank 17th among the 200 largest publicly listed companies included in the ranking, which assesses revenue derived from sustainable activities in accordance with Corporate Knights’ Sustainable Economy Taxonomy. This recognition highlights Iberdrola’s ability to combine sustainability, energy security and competitiveness through its commitment to electrification.

Clean200 is a joint initiative between As You Sow, a global leader in values-aligned investing, and Corporate Knights, an international organisation dedicated to advancing a sustainable economy. Since its launch in 2016, the ranking has consistently shown that companies focused on clean energy outperform those linked to fossil fuels.

This international recognition adds to other recent distinctions. Iberdrola is ranked among the leading electricity companies in S&P’s Sustainability Yearbook 2026 and remains a constituent of the Dow Jones Best-in-Class Indices for the 25th consecutive year, making it the only European utility included since the index was created. The company has also once again earned a place on the CDP “A List” and is included in the world’s leading ESG indices and ratings, including Moody’s ESG, MSCI, Sustainalytics, ISS-ESG, EcoVadis and FTSE4Good.
