The international non-profit organization, CDP (formerly Carbon Disclosure Project) has established the world’s largest repository of data on key environmental parameters (particularly carbon and energy) as reported voluntarily by companies and cities.  Climate data is collected from over 5,000 companies annually and used for investment decisions by many organizations, including financial information platforms. Thus, it is important that the climate data submitted are accurate and supported by reasonable assumptions. One of CDP’s strategic aims is to promote third-party verification as an integral part of the disclosure process to meet the growing demand for reliable and accurate data.

Importance of Third-Party Verification 

Numerous benefits are realized by a reporting entity from an independent verification of CDP climate change and sustainability data and information.  

  • Higher CDP response scores
  • Improved stakeholder perceptions
  • Increased data reliability
  • Carbon inventory improvement
