Why disclose environmental data?

Demand for environmental disclosure has increased significantly. Business and public sector leaders have noted the importance of transparency on environmental issues, with many national governments making environmental disclosure mandatory.

CDP’s data enables capital market actors to compare companies’ environmental commitments and performance for informed decision-making. It’s why hundreds of financial institutions with US$110 trillion in assets are requesting companies to disclose in 2026 – proof that the market values and continues to demand comprehensive environmental information.

Across all companies scored by CDP in 2025, 15% of companies are pulling ahead as environmental leaders, cutting emissions four times faster and unlocking US$218bn in value in the past year.

These range from transition plans and deforestation to supply chain duties. Reporting key environmental data is now mandatory in many major and emerging markets. Our “write once, use many” approach ensures organizations can turn a single disclosure into powerful market intelligence that fuels decision-making at all levels. Disclosing through CDP provides a competitive edge and enables organizations to get ahead of incoming regulation and market demands.

Environmental risk is financial risk, and the impacts are intensifying. Extreme weather, water scarcity, deforestation, plastics, and biodiversity loss are creating a domino effect of operational and financial pressures for businesses – yet they’re often overlooked.  

Scope 3 emissions are on average 26 times greater than a company’s operational emissions – yet many companies still lack visibility over their supply chains. Failing to measure and manage these supply chain impacts creates major blind spots, leaving businesses exposed to hidden environmental risks, missed opportunities and mounting regulatory pressure. 

CDP’s Supply Chain program enables members – over 270 leading corporate buyers – to track supplier impacts across climate, nature and plastics, providing actionable data to manage risks, meet regulatory requirements, and make smarter decisions. In 2025, almost 45,000 suppliers were requested to disclose through the program.

These include ICLEI, C40, WWF One Planet City Challenge, the Global Covenant of Mayors for Climate & Energy, RegionsAdapt Initiative, and Under2 Coalition. You can also measure your progress against UN-backed climate campaigns such as Race to Zero and Race to Resilience. CDP-ICLEI Track streamlines your reporting experience through one questionnaire.

These include investors and companies. All data is uploaded to our Open Data Portal so you can compare and benchmark progress over time.

Data collated from cities, states and regions is central to informing policy and decision-making on the road to an Earth-positive economy. By reporting through CDP, your impact reaches far beyond the city boundaries and is used by entities such as the United Nations, the IPCC, and World Bank.
