Iberdrola is the world’s most sustainable electricity company for the seventh consecutive year, according to the Clean200 ranking prepared by Corporate Knights and As You Sow, after analysing more than 8,000 corporations worldwide.

Since the previous edition, the company has climbed five positions to rank 17 among the 200 largest listed companies included in the classification based on their revenues derived from sustainable activities, in accordance with Corporate Knights’ Sustainable Economy Taxonomy. With this achievement, Iberdrola demonstrates that it combines sustainability, energy security and competitiveness in its drive for electrification.

Clean200 is a joint initiative by As You Sow, a global leader in values-aligned investment, and Corporate Knights, an international firm dedicated to advancing a sustainable economy. Since its creation in 2016, this list has shown that companies focused on clean energy clearly outperform those linked to fossil fuels.

This international recognition adds to other recent distinctions: Iberdrola stands out among the leading companies in the electricity sector in the Sustainability Yearbook 2026 by S&P. It is also ranked among the top-performing companies in the Dow Jones Best-in-Class Indices, where it has been listed for 25 consecutive years, making it the only European utility to have been included in this select index since its creation. In addition, it once again receives CDP’s “A List” rating and is included in the main global ESG indices and ratings, including Moody’s ESG, MSCI, Sustainalytics, ISS-ESG, EcoVadis and FTSE4Good.
