As for NSF 355, despite the name this standard is not really a "greener chemicals and processes" document as it does not offer metrics or a method (e.g., GreenScreen) to evaluate any of the chemicals reported by the standard and determine their relative health or sustainability anywhere along the life cycle. It does provide standardized data about the chemicals addressed which could facilitate comparisons between chemicals, albeit only "gate to gate" excluding all extraction information. It is quite controversial in the environmental health community as it does not require reporting of endocrine disrupting chemicals. I do not know of a published disclosure under 355 yet.
