Clean200 2026

Just a decade ago, many questioned whether sustainability could meaningfully drive global markets. Today, publicly traded companies generating substantial revenue from clean energy, electrification, efficiency, and enabling technologies are reshaping the global economy.

The 13th edition of the Carbon Clean 200™ (Clean200™) identifies 200 companies selected from more than 8,200 global firms through a rigorous revenue-based methodology. On average, these companies now derive more than half of their revenue from sustainable activities, representing trillions of dollars in annual sustainable revenue.

The Clean200 highlights the corporate leaders advancing the transition to a low-carbon economy — and demonstrates that markets continue to reward companies aligned with long-term sustainability fundamentals.
