The purpose of the Greener Chemicals and Processes Information Standard is to provide the chemicalenterprise with a voluntary and standardized way to define and report the primary categories ofinformation, their respective data elements, and data quality objectives pertaining to the relativegreenness of a chemical product and its manufacturing process within one stage (i.e., gate-to-gate, asdefined in 4) of its life cycle. This information shall be provided by suppliers to communicate clearly, withtransparency and consistency, to help customers evaluate the relative greenness of a chemical productand process. The intent is for this information to be informative to life cycle assessments, but is not a lifecycle assessment itself.

The Standard further stipulates reporting a minimum set of social responsibility criteria that are applied tothe product and process claiming conformance.
