Factory Data– Outputs– Inputs – Energy– Transport– Emissions – Waste

Weightings
– Required to achieve relative importance
– ..and for a single score– Created by a panel of 10
European experts.– Peer reviewed– Geographically specific to
Europe
– Basis of BRE Ecopoints
100 Ecopoints = impact of 1 EU citizen per year

What don’t you get from an Environmental Profile?
Qualitative Impacts
- Responsible sourcing - Social impacts
Economic Impacts - Life cycle costing
Physical Properties- Thermal properties- Acoustic properties
Emissions In-situ- IAQ and VOCs

Benefits of an Environmental Profile
• Green Guide Rating can be used to compare:– Materials with similar functions– Specifications with similar functions– Building designs over their expected
lifetimes
• Credits in BREEAM
• Product differentiation
• Competitive advantage
• Open new markets
![Page 19: Environmental Profiling and EN15804 EPDs](https://reader035.vdocuments.us/reader035/viewer/2022081503/568168b9550346895ddfa2c9/html5/thumbnails/19.jpg)
Cross-listing against Existing Certificates
Criteria for cross-listing:– The product to be cross-listed against must
have an existing Environmental Profile Certification.
– The product to be cross-listed must have no additional manufacturing by the owner or by the company buying in the product. (It is the same product that has been certified e.g. re-branded with a different name)
– Cross listing is dependent upon valid certification of original product.
