For this report, CDP has selected 2 separate samples; a sample of all 6,937 companies that responded to CDP’s climate change questionnaire in 2018; and a global 500 sample based on market cap.
For this report, we have also provided some high-level analysis of the full 6,937 companies that responded to CDP’s climate change questionnaire, and covers companies responding to investor, and supply chain member requests. This was done to provide a more holistic view of CDP’s reporting population and identify key trends at an industry or geographic level.
CDP created a global 500 sample using Bloomberg's Terminal. We identified the 500 biggest corporates by market capitalization on the day of extraction (13th February 2019). Of the 500 sample, 366 (73%) responded to CDP's climate change questionnaire in 2018. These 366 companies represent USD$28.7 trillion of market cap, or 74% of the total global 500's market cap, USD$38.9 trillion.
