EU-GPP for Roads
1.3.2 How the life cycle impacts of construction materials are addressed
The award criteria available to procurers are, in decreasing level of ambition and technical complexity, as follows
1. Life Cycle Assessment (LCA): The carrying out of a Life Cycle Assessment (see comprehensive criterion B14). This requires bidders to evaluate the life cycle impacts of the main road elements.
6
EU-GPP for Roads
The following stages in the procurement process …..
A. Selection of the design team and contractors;
B. Detailed design and performance requirements;
C. Construction or major extensions;
D. Use of the road;
E. Maintenance and operation;
F. End of life

EU-GPP for Roads
B14.LCA performance of the main road elements ….
This criterion may only be applied where a Bill of Quantities for a reference road is to be provided to bidders as the basis for comparison or where designs submitted by different bidders are to be compared during a competitive process.
Additional technical guidance shall be followed during the procurement process, as provided in Annex B (LCA option).

EU-GPP for Roads
Annex B Supporting guidance for criterionB14(comprehensive criterion): Option 2 -LCA analysis
As a minimum the following impact category indicators, identified in EN 15804, shall be used:
• Global Warming Potential (GWP);
• Formation potential of tropospheric ozone photochemical oxidants(POCP);
• Depletion potential of the stratospheric ozone layer (ODP);
• Acidification potential of soil and water (AP);
• Eutrophication potential (EP);
• Abiotic Resource Depletion Potential for elements(ADP_elements);
• Abiotic Resource Depletion Potential of fossil fuels (ADP_fossil fuels)
