CDP 2011 disclosure scores


 Introduction to carbon disclosure scores


The disclosure score reflects the comprehensiveness of a company’s response in terms of the depth and breadth of its answers. The score is normalized to a 100-point scale and covers issues such as:

  • The extent to which a company measures its carbon emissions
  • The comprehensiveness of the information that it provides on climate-related actions
  • The depth of information given on the issues climate change presents to the business
  • Whether a company uses a third party for external verification of its data in order to promote greater confidence and usage of the data.

Not all company responses are scored. Some samples – samples are groups of companies based on market capitalization – are not scored.

It is important to note that the carbon disclosure score is not a metric of a company’s performance in relation to climate change management, because the score does not make any judgment about mitigation actions. A company’s disclosure score is based solely on the information disclosed in the company’s CDP response.


 What does a CDP carbon disclosure score represent?


Generally, companies scoring within a particular range suggest levels of commitment to, and experience of, carbon disclosure. Indicative descriptions of these levels are provided below for guidance only; data-users should read individual company responses to understand the context for each business.

High (>70)
Senior management understand the business issues related to climate change and are building climate related risks and opportunities into core business.

Midrange (50–70)
Increased understanding and measurement of company-specific risks and opportunities related to climate change.

Low (<50)
Limited or restricted ability to measure and disclose climate related risks, opportunities and overall carbon emissions.

  • Be among the top-scoring companies. The threshold for inclusion is set by the report-writer for their sample.
