Green guide

The BRE Green Guide assesses building materials and components in terms of their environmental impact across their entire life cycle. It is part of BREEAM (BRE Environmental Assessment Method) an accredited environmental rating scheme for buildings.

This data in the Green Guide is set out as an A+ to E ranking system, where A+ represents the best environmental performance / least environmental impact, and E the worst environmental performance / most environmental impact. BRE has provided a summary environmental rating – The Green Guide rating, which is a measure of overall environmental impacts.
