BRE Environmental Profile
Type III Environmental Product Declarations (EPD) based on following standards:
– ISO 14040:2006 and ISO 14044: 2006 Life Cycle Assessment
– ISO 14025: 2006 Type III Environmental Labels
– ISO 21930: 2007 Environmental Product Declarations for Construction Products

BRE Impact Categories Units
Climate change Kg CO2 eq. (100 yr)
Water extraction m3 water extracted (gross)
Mineral resource extraction Tonnes of mineral extracted
Stratospheric ozone depletion Kg CFC-11 eq.
Human toxicity Kg 1,4 dichlorobenzene (1,4-DB) eq.
Ecotoxicity to fresh water Kg 1,4 dichlorobenzene (1,4-DB) eq.
Nuclear waste (higher level) mm3 high level waste
Ecotoxicity to land Kg 1,4 dichlorobenzene (1,4-DB) eq.
Waste disposal Tonnes of solid waste
Fossil fuel depletion MJ
Eutrophication Kg phosphate (PO4) eq.
Photochemical ozone creation Kg ethene (C2H4) eq.
Acidification Kg sulphur dioxide (SO2) eq.
Normalisation
– The impact of one European citizen per year
– Allows direct comparison of impacts
Environmental Issue Impact
Climate Change 12.3 t CO2 eq. (100 yr)
Water extraction 377m3
Mineral extraction 24.4 tonnes
Stratospheric ozone depletion 0.217 kg CFC-11 eq.
Human toxicity 19.7 t 1,4-DB eq.
Ecotoxicity to fresh water 13.2 t 1,4-DB eq.
Higher level nuclear waste 23700 mm3
Ecotoxicity to land 123 kg 1,4-DB eq.
Waste disposal 3.75 tonnes
Fossil fuel depletion 6.51 toe
Eutrophication 32.5 kg PO4 eq.
Photochemical ozone creation 21.5 kg C2H4 eq.
Acidification 71.2 kg SO2 eq.
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 do you get from an Environmental Profile?

Environmental Profiles Report
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
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.
