CDP: Global Environmental Disclosure System

CDP operates the world's largest environmental disclosure system, maintaining the richest and most comprehensive dataset on corporate and governmental environmental action. Since 2000, CDP has mobilised stakeholders across enterprise, capital markets, policy, and science.

Overview

CDP (formerly Carbon Disclosure Project) is an independent, not-for-profit organisation running the global disclosure system for investors, companies, cities, states and regions to manage their environmental impacts. The platform covers climate change, water security, forests, and plastics. Organisations can disclose through CDP either at the request of Capital Markets Signatories (major investors) or as Self-Selected Companies demonstrating voluntary commitment. With operations across 50+ locations and 90+ countries, CDP provides the standardised framework that enables meaningful comparison and drives environmental action globally.

Frequently Asked Questions

Common questions about CDP compliance

What are the CDP scoring levels?
CDP uses an A to F scoring scale: A (Leadership) demonstrates best practices and environmental stewardship; B (Management) shows good environmental management; C (Awareness) indicates understanding of environmental issues; D (Disclosure) represents the initial reporting step; F indicates insufficient information or no response.
Is CDP disclosure mandatory?
CDP disclosure is currently voluntary for most organisations. However, companies may be requested to disclose by investors (Capital Markets Signatories) or customers (Supply Chain members). The global trend is toward mandatory environmental reporting, and CDP helps prepare organisations for future requirements.
What does CDP disclosure cost?
Administrative fees range from $1,055 to $6,500 depending on the service tier (Essential, Foundation, or Enhanced). Some exemptions apply for organisations only requested through Supply Chain membership or certain investor programs.
How do I achieve an A-list score?
A-list companies demonstrate leadership through comprehensive disclosure, verified emissions data, science-based targets, and evidence of environmental best practices. Third-party verification of emissions is typically required for A-list consideration.
What verification is required?
100% verification is required for Scope 1 and Scope 2 emissions to be scored. Third-party verification is encouraged and typically required for higher scores. CDP provides guidance on acceptable verification standards.
When are CDP questionnaires open?
CDP questionnaires typically open in April each year, with a submission deadline in early July. Scores are released at year-end or early in the following year. A-list companies are publicly announced.
Can private companies disclose through CDP?
Yes, private companies can disclose through CDP's Private Markets platform or as Self-Selected Companies. This demonstrates voluntary commitment to environmental transparency and helps prepare for future reporting requirements.
How does CDP align with TCFD?
CDP questionnaires are aligned with TCFD recommendations, covering governance, strategy, risk management, and metrics and targets. Completing CDP disclosure provides much of the information needed for TCFD-aligned reporting.
