CDP Global 500 Report 2011: Accelerating Low Carbon Growth

The 2011 edition of the annual CDP Global 500 report examines the carbon reduction activities at the world’s largest public corporations.


2011 Leaders

Introduction to the Carbon Disclosure Leadership Index (CDLI) and the Carbon Performance Leadership Index (CPLI)

Each year, company responses are reviewed, analyzed and scored for the quality of disclosure and performance on actions taken to mitigate climate change. This results in a disclosure score and, where sufficient disclosure exists, a performance score.


Disclosure scores

  • Disclosure scores are an assessment of the quality and completeness of a company’s response; they are not a measure of a company’s performance in relation to climate change management
  • Scores are plotted over a 100-point normalized scale
  • Companies are assessed based on their level of disclosure of carbon emissions measurement techniques and subsequent public disclosure
  • Companies with the highest disclosure scores are listed in the CDLI

Performance bands

  • Where a company’s disclosure score is 50 or more, its performance in contributing to climate change mitigation, adaptation and transparency is assessed and ranked in a performance band
  • In 2011 there are six performance bands (there were four bands in 2010)
  • Companies with the highest performance bands that meet additional CPLI criteria are listed in the CPLI

Analysis of the CDLI and CPLI provides insights into the characteristics and common trends among the leading companies on carbon disclosure, and highlights good practices in reporting, governance, risk management, emissions reductions and other areas. Interrelations between the CDLI and CPLI companies are analyzed to determine if those companies with better data use it within the business to drive value adding activities. The financial performance of CDLI and CPLI companies is examined and compared against the benchmark index of the Global 500.
