We are working on a big box store in Europe striving to achieve this credit, but differences between the standard Green Label Plus and ACP approaches seems to be causing questions related specifically to caprolactum. We have found a supplier of a carpet with GUT certification, which in almost every category seems to be more stringent than CRI requirements; however, we have been unable to determine whether/how much caprolactam may or may not be in the carpet. As this substance is specifically mentioned in the text of the ACP, we are concerned GBCI may reject our selection and prevent us from earning the IEQc4.3 credit. Does anyone have any experience or additional useful knowledge related to this potential issue?

Under the potentially useful category, I was looking at IARC categories today and your caprolactam is the only Group 4 chemical/compound listed which means that is it is 'potentially not carcinogenic to humans'. Since IARC is a cancer registry, there is likely no correlation between that and VOCs. But I found it interesting when I read your post after reading that this morning. (We're working on a cancer center.)
Wiki says it is a precursor to Nylon 6 which is in a lot of carpets in the US and is a better place to start.
