text: CDP recognizes companies with high-quality disclosure in its annual scoring process, with top companies making it onto CDP's so-called A-list.
  Scores are calculated according to a standardized method which measures whether and how well a company responds to each question. A company goes through four main steps, starting with disclosure of their current position, moving to awareness which looks at whether a company is conscious of its environmental impact, to management, and finally leadership.
  A high CDP score is supposed to be indicative of a company's environmental awareness, advanced sustainability governance and leadership to address climate change.
