Some 877 companies have earned a place on CDP‘s 2025 Corporate ‘A List’, with 23 firms achieving a ‘Triple A’ ranking for leadership across climate change, forests and security.
The 877 firms named on the Corporate A List span all regions and sectors, the environmental disclosure platform noted, with companies located in Asia and Europe performing strongest – some 12% of A List firms were located in Japan, with a similar percentage in France and Türkiye. Representation was also high in Taiwan (8%), Portugal (9%) and Spain (9%).
The top firms account for 4% of the 22,000 organisations that were assessed for this year’s A List rankings, with more than 23,100 companies, cities, states and regions disclosing information through CDP in 2025.
‘An unmistakable signal’
“Markets are sending an unmistakable signal: clear, consistent environmental data is indispensable for sound decision-making,” commented Sherry Madera, CEO of CDP.
“The momentum behind disclosure in 2025 shows that organisations of every size and sector recognise the value of transparent information to strengthen resilience, support innovation and unlock investment. CDP’s A List reflects the leading examples of this ambition, but the real story lies in the global commitment to making environmental data visible and actionable. As investors, policymakers and companies rely ever more heavily on these insights, disclosure remains one of the most powerful drivers of Earth-positive progress.”

Environmental disclosure
Last year, 640 investors representing $127 trillion in assets requested environmental disclosure through CDP, while more than 270 major buyers sought information from approximately 45,000 suppliers through CDP’s Supply Chain programme.
CDP noted that since 2023, there has been ‘steady growth’ in the number of A scores achieved for climate (from 346 in 2023 to 751 in 2025), water security (from 101 in 2023 to 263 in 2025) and forests (from 30 in 2023 to 55 in 2025), indicating a ‘growing recognition by companies that climate and nature issues are deeply interconnected and must be addressed in parallel’.
There has also been an increase in the number of sub-national governments seeking to strengthen their climate and nature governance through disclosure, with more than 1,000 cities, states and regions reporting environmental information last year. Read more here.
