Changes to the 2026 questionnaire
From accelerating climate impacts to resource insecurity and biodiversity loss, markets need intelligence that fills critical data gaps. High-quality data helps organizations navigate risk, build resilience and identify opportunities for Earth-positive action.

We are committed to:
Deepening alignment with global standards;
Expanding our coverage to ocean; and

CDP’s single corporate questionnaire empowers companies to better assess the full extent of the environmental risks, impacts and opportunities in their operations, supply chain, product and service offerings, and financial decisions, and to understand how environmental relationships are connected. A record 3,500+ companies disclosed on climate change, deforestation and water security together in 2025.
