CDP and the Global Reporting Initiative (GRI) have published a detailed document explaining the similarities and differences between the GRI’s G4 Guidelines and CDP’s 2015 climate change questionnaire and CDP’s 2015 water questionnaire for the first time. The linkage document outlines how reporters can efficiently use or adapt the same data in both reporting processes, and links CDP questions to GRI indicators and also GRI indicators to CDP questions. It is hope that this approach will make the document more helpful for companies.

The document about how GRI's G4 guidelines and CDP's 2015 climate change questions are aligned is available on following link.
