This ranking highlights the companies that are spearheading the transition to a clean energy future, underscoring the commitment of global corporations to sustainability and environmental responsibility.
The Clean200 ranking is a widely respected index that identifies the 200 largest publicly listed companies based on their clean revenues, following the definitions outlined in the Corporate Knights’ Sustainable Economy Taxonomy. Iberdrola’s consistent presence at the top of this list reinforces its leadership in sustainable energy and corporate environmental responsibility.
