It has been recognised that, due to the withdrawal of the Green Guide methodology in the current version of BREEAM UK New Construction, some manufacturers are not updating their product certifications against this environmental profiling scheme.
Therefore, where robust evidence can be provided that the composition and properties of such products or materials have not changed since they were certified, the expired Green Guide Rating may be used, where available.
This supersedes the guidance previously provided in relation to Green Guide validity in KBCN0798
