Environmental footprint
The Environmental Footprint (EF) is part of the GSES Sustainable Product Footprint certification. The EF is based on existing life cycle assessment (LCA) standards: ISO14040, ISO14044, PEF, ISO14025 and EN15804.
The following LCA indicators (Cradle to Gate) are measured and registered in GSES’ EF:
- Global warming potential (kg CO2);
- Freshwater use (l fresh water);
- Acidification Potential (mol H+ eq)
- Energy, primary, non-renewable use (MJ)
| EF pillar indicator | Scoring indicators EF (0% - 100%) | |
|---|---|---|
|
Global Warming Potential (GWP in kg CO2eq) Cradle to Gate per kg product |
0%, 10%, 25% Building products without an LCA/EPD: 0%, 5%, 15% |
High = 0% for GWP > 0,5 CO2eq/kg Medium = 10% for 0 < GWP <0,5 CO2eq/kg Low = 25% for GWP < 0 CO2eq/kg |
|
Acidification Potential (ADP in mol H+ eq) Cradle to Gate per kg product |
0%, 10%, 25% Building products without an LCA/EPD: 0%, 5%, 15% |
High = 0% for AD > Om05 mol H+ eq/kg Medium = 5% for 0,01 < AD < 0,05 mol H+ eq/kg Low = 15% for AD < 0,01 mol H+ eq / kg |
|
Energy, primary, non-renewable (PENRT in MJ) Cradle to Gate per kg product |
0%, 10%, 25% Building products without an LCA/EPD: 0%, 5%, 15% |
High = 0% for PENRT > 100 MJ/kg Medium = 10% for 5 < PENRT < 100 MJ/kg Low = 25% for PENRT < 5 MJ / kg |
|
Fresh water use (FW in I*) Cradle to Gate per kg product |
0%, 10%, 25% Building products without an LCA/EPD: 0%, 5%, 15% |
High = 0% for FW > 100 l/kg Medium = 5% for 5 < FW < 1001/kg Low = 15% for FW < 51/kg |
