Our Question Bank
CDP is committed to turning a single disclosure into powerful market intelligence that supports organizations to make Earth-positive decisions. We work tirelessly to ensure our question bank can be used by a wide range of stakeholders, including capital markets actors, regulators, and supply chain partners.
CDP’s approach to simplifying disclosure is our unrivalled alignment with the existing body of frameworks and standards. In 2026, we have made questionnaire updates to strengthen our alignment across the board: expanding to ocean for the first time, enhancing our forests scope, and improving plastics questions.

CDP runs the world’s only independent environmental disclosure system, evolving our questionnaire and forging powerful partnerships to ensure disclosed data goes further and faster.
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.
Note, cities, states and regions disclose on climate only through their respective questionnaires, while the States and Regions questionnaire has a forests module.

Improving corporate awareness through measurement and disclosure is essential to the effective management of carbon and climate change risk.
Water Security
The world faces a water crisis impacting the stability of the global economy – a major financial risk to companies that also serves as a significant opportunity.

Forests
CDP provides companies, financial institutions, states and regions with opportunities to measure and manage their forest-related dependencies, impacts, risks and opportunities.

Plastics
CDP is committed to scaling plastics disclosure and encouraging a shift from a linear model of plastics production, commercialization and usage to a circular economy.

Biodiversity
Companies and capital markets can measure their biodiversity-related dependencies to better manage their impact, risks and opportunities.
