CDP
As the founder of environmental reporting, we believe in transparency and the power of data to drive change. Partnering with leaders in enterprise, capital, policy and science, we surface the information needed to enable Earth-positive decisions. We supported more than 22,100 companies and over 1,000 cities, states and regionsdisclose their environmental impacts in 2025. Financial institutions with more than a quarter of the world’s institutional assets use CDP data to help inform investment and lending decisions. Our team is truly global, united by our shared desire to build a world where people, planet and profit are truly balanced. To meet the scale and speed of today’s environmental challenges and market expectations, CDP is becoming two separate organizations – a commercial entity, CDP, and a non-profit CDP Foundation. They will be united in shared ambition: to surface new information, enabling Earth-positive decisions to protect future generations. More information to follow.
